25 tons capacity heavy oil steam boiler

25 tons capacity heavy oil steam boiler

The electric boiler, also known as the electric water boiler, the electric drinking water boiler, the electric tea boiler, and the electric tea stove, is divided into two types: continuous electric water boiler and split tank electric water boiler, which are designed to meet the needs of more people drinking boiled water. A kind of drinking water equipment using electric energy to produce hot water is developed, which is mainly suitable for the use of schools, hospitals, factories, supermarkets, shopping malls and other population-intensive units. The main component of the electric water heater is the electric heating tube which plays the role of heating. It is better to choose the electric heating tube with insulating material, which has high safety factor and long service life. Under normal conditions, it can work for 6-7 years. The electric hot water boiler is also called the electric heating boiler, the electric bath boiler, etc. The electric hot water boiler is the production hot water that adopts the latest electric heating technology and the control system design, satisfies the heating or the supply life, Fully automatic environmental protection boiler of hot water for bath. This kind of boiler is suitable for hot water and heating in hotels, villas, factory buildings, office buildings, government agencies, colleges and universities, hospitals, troops and other places with high appearance requirements. The electric boiler is divided into two types: direct heating type electric boiler and regenerative type electric boiler. As the name implies, the direct heat type electric boiler is no longer explained here, and the regenerative type electric boiler is based on The power sector encourages electricity heating during trough periods and enjoys preferential electricity prices, introducing a new, efficient and energy-efficient electric heating product. Regenerative type electric boiler is composed of heat storage water tank and auxiliary equipment, which makes use of hot water heating in heat storage tank to achieve the goal of using all or part of the low valley power from the purpose of making use of the hot water in the heat storage tank. Electric 25 tons capacity steam boiler is also called electric steam boiler. Electric steam boiler is a steam boiler which uses power source to heat and produce rated pressure. Steam boilers can be used in textile, printing and dyeing, paper making, food, rubber, plastics, chemical, pharmaceutical, iron and steel, metallurgy and other industrial products processing process Steam is required and can be used for heating, bathing, air conditioning and hot water in enterprises, institutions, hotels, schools, catering, and service industries.

01. The reason why the ignition rod of gas-fired boiler burner does not ignite: 1. There is carbon slag in the gap of the ignition rod, there is oil pollution. 2, the ignition rod is cracked. Damp. Leakage. 3. The distance between the ignition rod is not right, too long or short. 4, the distance between the ignition rod is not right, it is too long or short. 4. Ignition rod insulation outer skin is damaged, short circuit to the ground. 5, ignition cable and transformer failure: cable broken, connector damage caused by short circuit fire; The transformer is out of line or out of order. Gas-fired boiler burners failure, ignition rod non-ignition treatment measures are as follows: clear, replace, adjust distance, change wire, change transformer. Second, the reason why the ignition rod of the gas-fired boiler has sparks but does not ignite: 1. The ventilation clearance of the cyclone disc is blocked by carbon deposition and the ventilation is poor. 2, the oil nozzles are unclean, clogged or worn. 3, the setting angle of the air door is too small. 4, the distance between the tip of the ignition rod and the leading edge of the oil nozzle is inappropriate (too prominent or indented) 5, The solenoid valve of the first oil gun is blocked by debris (small fire gun) .6, the oil quality is too viscous to flow or the filtration system is clogged or the oil valve is not opened, which causes the oil pump to absorb insufficient oil, the oil pressure is low. 7, the filter of the pump itself is blocked. 8, Oil contains more water (boiling noise in heater). The measures to deal with spark but not ignition of ignition rod of gas-fired boiler are as follows: clearing; cleaning first, if no replacement; adjusting test; adjusting distance (3~4mm is good); remove cleaning (cleaning parts with diesel); check pipes and oil filters, insulation equipment; remove oil pump outer screws, carefully remove the outer cover and remove the inside net, wash with diesel; replace it with new oil. Third, when a small fire of a gas-fired boiler is turned into a fire, the reasons for its extinction or flickering instability are as follows: (1) the air volume of the air outlet of the fire is set too large. 2, The oil valve fretting switch (the outermost group) of the fire is improperly set (set higher than the air flow of the fire valve) .3, the viscosity of the oil is too high and not easy to atomize (heavy oil). 4, the distance between the cyclone disc and the nozzle is inappropriate. 5, To wear or soiled the nozzles of a fire. 6.The heating temperature of the reserve oil tank is too high, causing the steam to cause the oil pump to send oil unsmoothly. 7, the oil in the burning oil and gas hot water boiler contains water. Treatment measures to extinguish or flicker unstable when small fire of gas-fired boiler turns to fire normally: reduce test step by step; raise heating temperature; adjust distance (between 0~10mm); clean or replace; set about 50 ℃ or so; change oil or drain water. 4. Causes of noise increase in gas boiler burners: 1, shut-off valve or insufficient oil intake in the oil path, blocking of oil filter. 2, low inlet temperature, too high viscosity or too high intake temperature of pump. 3, oil pump failure. 4, oil filter blocking. 4, oil inlet temperature is low, viscosity is too high or pump inlet temperature is too high. 3. Fan motor bearing Damage. 5, fan impeller is too dirty. Treatment method for increasing noise of Burner in Gas-fired Boiler: (1) check whether the valve in the pipeline is open or not, and the oil filter is working normally. Cleaning pump itself filter screen. 2 oil heating or lowering oil temperature. 3 replacement pump. 4 replacement motor or bearing. 5 cleaning fan impeller.

01: the greatest benefit of economic use of gas-fired steam boilers is that they can save large amounts of material costs for enterprise users, without the need to spend heavy money on large amounts of coal-carbon fuel. Only clean natural gas can be used to burn and release the steam used. Natural gas can also increase the thermal effect and reduce the cost of material input for users. Safety: natural gas is well known as one of the safest non-toxic and pollution-free clean fuels, unlike liquefied gas or gas leaks that precipitate on the ground and even cause accidents. Gas-fired steam boiler is the safest way to choose natural gas in the process of transporting gas, and it is easy to leak. Being found to be used is therefore the safest way to use it. 3: the convenient gas-fired steam boiler is also the most convenient one in use, so it will be favored by the customers of various enterprises. Natural gas pipelines are as convenient as tap water for domestic use, and sustainable use will not be bothering you. It eliminates the cumbersome work such as transporting or stacking coal and cleaning coal residue. 4: clean gas-fired steam boilers are highly rated in the market because they are clean and clean in use and free of black pot bottom and exhaust gas pollution. So it's cleaner than any other boiler in use. One way, whether directed at operational work or surrounding residents or the business itself, can be cleaner without compromising physical and mental health.

After electric 25 tons capacity steam boiler shutdown, how to carry out maintenance in the long-term disabled electric steam boiler, furnace should pay great attention to external corrosion and maintenance problems. First, after power shutdown cooling steam boiler, the ash must be thoroughly cleaned and the heating surface fouling the upper grate, the lower portion of the furnace. Then to maintain a certain degree of natural ventilation flue. In general, in order desiccant moisture should be placed in the furnace, flue. The quicklime as a drying agent, within the furnace or flue gas per cubic meter should be placed generally about 3kg. After placing all the ventilation should be tightly closed doors. After the change of lime powder to be replaced. Low-lying position as boiler room, ground during shutdown severe flood tide, often approach should be used and placed a small fire to dry desiccant combination. If the boiler shutdown a long time, after the complete removal of soot coated with an anti-corrosion red lead paint in oil or other metal surface furnace. As for anti-corrosion maintenance methods inside the furnace shutdown, the shutdown Yaoan the length of time to be. In general, no more than one month shutdown maintenance wet available, more than one month should be taken to maintain dry. To note the following problems when a dry maintenance: desiccant boiler not in direct contact with the metal surface, may be mounted in a container such as the iron plate after the desiccant is placed, and a hole for shutting the other hand hole cover, valve steam, the water pipe change must cut lime powder should be replaced.

Beiqi Panther car 6 tons of steam condensing one fuel gas 25 tons capacity steam boiler project has been successfully completed. This series boiler adopt advanced design concepts, using the waste heat of flue gas cascade, with the use of the condenser and the economizer fully absorb the waste heat in the flue gas, the boiler efficiency has been greatly improved.

Why boiler furnace exhaust gas temperature increases heat losses the heat loss is largest in a boiler, furnace 6% is generally fed to the heat, the exhaust gas temperature increasing every 12 ~ 15 ℃, heat losses to an increase of 0.5%. Therefore, the exhaust gas temperature is one of the most important indicators boiler operation. Here are a few reasons may cause the furnace exhaust gas temperature rise: (1) heating surface slagging, fouling. Whether waterwall slagging furnace fouling, or superheater, convection bank, and economizer preheater fouling are due to increased resistance measured smoke, heat deterioration of the cooling effect deteriorates the flue gas, resulting in increased exhaust gas temperature. (2) the excess air ratio is too large. Under normal circumstances, the furnace outlet increases as the excess air ratio of the exhaust gas temperature rises. After the excess air ratio increases, while the amount of smoke increases, the speed increase of smoke, heat strengthening of exiled, but less than the degree of increase in heat transfer gas volume increases more. It will be appreciated as the tobacco rate increased, the time to heat to the flue gas working fluid left the heating surface. (3) leakage factor is too large. Tail shaft furnace and boiler flue negative pressure leakage is inevitable, and provides a heating surface allowed leakage coefficient. When the coefficient of air leakage increases, the influence of the exhaust gas temperature and overfire air coefficient increases similarly. And the closer the leakage furnace, exhaust gas temperature raising effect on the greater. (4) water temperature. When the turbine load is low or high pressure splitting when the heater temperature of the boiler feedwater will decrease. Generally, when the water temperature rises, if the amount of fuel is maintained constant, the temperature difference decreases economizer, economizer heat absorption decreases the exhaust gas temperature rises. (5) the fuel moisture. The fuel in the flue gas to increase the amount of water increases, and therefore the exhaust gas temperature rises. (6) boiler load. Although the boiler load increases, the amount of smoke, the amount of steam to the water, the air amount increases in proportion, but since the furnace exit gas temperature is increased, so that the exhaust gas temperature rises. After the load is increased to increase the furnace outlet temperature, followed by convection heating surface temperature difference increases, an increase in heat absorption, the more so the convection heating surface, the smaller the impact load change of a boiler exhaust gas temperature. (7) The fuel species. When burning low calorific value gas, since the furnace temperature is lowered to reduce the radiation heat transfer in the furnace, the low calorific value gas in a non-combustible components, mainly N2, CO2, H2O more, the amount of flue gas increases, the exhaust gas temperature rise high. Pulverized after burning oil, although oil-fired furnace outlet when the excess air ratio than the coal is low, but the little ash fuel oil, and no larger soot particles, larger ash particles in the flue gas absent the cleaning action of surface heating, convection heating surface more polluting. So bad combustion, often black smoke boiler flue gas temperature. When the tail has means ash ball, since the tail cleaner, the exhaust gas temperature is slightly lower than the burning coal. (8) milling system operation. Bunker has a reservoir of closed milling system is concerned, when the pulverizing system is running, because a portion of the water in the fuel into the furnace, the furnace temperature is reduced and the amount of smoke increases, the leakage into the pulverizing system is running as the primary cold air air into the furnace, to reduce the amount of air flowing through the air preheater to the exhaust gas temperature rises. Conversely, when the exhaust gas temperature is reduced pulverizing system outage.
