Working principle and structural characteristics of 5 mw steam boiler

Steam boiler has brought great convenience to industry. Steam boiler has driven the development of the times. The following is a brief introduction to the structural characteristics and working principle of steam boiler. Steam boiler is a machine that mainly produces steam, and many people use it, but many of them do not know much about its structure and working principle. It makes use of coal, oil, natural gas and other water-tube steam boilers with limited capacity and pressure. There is a large desire to space, and easy to arrange, steam boiler in a variety of forms. Water is heated in the drum into steam, and the heat emitted by fire in the furnace is the principle of a steam boiler. Work of steam boiler Principle:

1, the heat generated by pulverized coal combustion in the furnace is first absorbed by the water wall through radiative heat transfer, and the water boiling of the water wall is vaporized, producing a large amount of steam into the steam drum for steam separation (except for direct flow furnaces). The separated saturated steam enters the superheater and continues to absorb the flue gas heat at the top of the furnace and the horizontal flue and the tail flue through radiation and convection, and enables the superheated steam to reach the required working temperature. The steam boiler for power generation is usually equipped with a reheater, which is used to heat the steam after the high-pressure cylinder does work, and the reheat steam comes out of the reheater to go back to the middle, and the low-pressure cylinder continues to do the work to generate electricity.

2. When the pulverized coal stove is working, The position of the center of the flame will affect the amount of evaporation, generally speaking, if the center of the flame is low, the amount of evaporation will be large, and the position of the center of the flame will also affect the temperature of the superheated steam or reheated steam, as well as the high value of the flame center and the small amount of evaporation. When the flame center is low, the superheated steam, especially the reheated steam temperature, will be low and vice versa.

3, the arrangement of burners, as far as coal powder furnace is concerned, there are many kinds of combustion modes, such as front and rear wall, tangential combustion, double tangential combustion, and so on, each of which has its own characteristics. The influence on steam can not be directly determined because the same furnace can not apply the above-mentioned arrangement methods at the same time.

Gas boiler Burner Failures and gas boiler burners Failures and - best  a gas boiler, gas boiler burner ignition misfire rod reasons: 1, the ignition bar gap interposed carbon residue with oil. 2, ignition rods fragmentation. moist. Leakage. 3, the distance between the ignition does not stick, too long or short. 4, ignition rods Insulation damage, short to ground. 5, ignition cable and transformer failure: cable, connector damage caused by a short circuit during ignition; transformer break or other fault occurs. Measures following five: Clear, renewal, adjust the distance, change and switching transformer. Second, gas boiler, but spark ignition rods misfire reasons: 1, the cyclone disc space ventilation is blocked carbon, poor ventilation. 2, dirty oil nozzle clogging or wear. 3, the throttle angle is set too small. 4, the firing bar from the leading edge from the oil nozzle tip inappropriate (too protruding or retracted) 5, the first solenoid valve is an oil debris blocking gun (gun small kerosene). 6, oily or too viscous to flow easily clogged or the oil filtration system the valve is not opened, so that insufficient suction pump, oil pressure. 7, the filter pump itself blocked. 8, the oil more water (boiling abnormal noise within the heater). Measures are: Clear; first wash, such as not renewed; turndown test; adjusting the distance (in 3 ~ 4mm as well); Remove cleaning (cleaning the parts diesel); Check tubing and oil filters, insulation equipment ; remove peripheral screw pump, carefully remove the cover inside out oil network, with immersion oil; renewal of the test oil. Third, when the gas boiler and turn the fire a small fire normal, off, or flashing instability reasons: 1, the air volume damper setting fire too. 2, oil fires micro switch valve (damper outermost that group) inappropriate setting (set throttle air flow rate is greater than the fire). 3, oleaginous easy to spray viscosity is too high (heavy). 4, and the nozzle plate spacing cyclone inappropriate. 5, fire nozzle worn or dirty. 6, the preliminary fuel tank temperature is too high, so that the steam not smooth oil pump oil feed. 7, fuel oil boiler water. Action: Test gradually reduced; heating temperature; adjusting the distance (between 0 ~ 10mm); clean or replace; approximately set to about 50 deg.] C; or drain oil change. Fourth, the noise increases gas boiler burner reasons: 1, cut-off valve is closed or the passage into the fuel shortage, an oil filter blockage. 2, the oil inlet temperature is low, the oil viscosity is too high or the temperature is too high the pump inlet. 3, oil pump failure. 4, fan motor bearing damage. 5, dirty fan impeller. Processing methods: ① the oil line check valve is open, if the oil filter is working properly, the filter cleaning pump itself. ② heating oil or reduce the oil temperature. ③ Replace the oil pump. ④ replace motor or bearings. ⑤ cleaning fan wheel.

April 8, 2019 China International Corrugated exhibition in Shanghai New International Expo Center, such as about the opening. Fast boiler as China's "most influential brand of industrial boilers," was invited to participate in the exhibition.

Check the bottom front of the hot water boiler to run fast boiler Henan small series for you to explain examination before the boiler 1, containing internal furnace inspection and application plans. 2. The stove and flue testing, stove and chimney soot and dirt should be removed. Gas hot water boiler with environmental protection, energy saving, Security Council, distinctive features automatic operation, it is very convenient application, and the other, since the operation of the tertiary industry, the New Deal judiciary incentive, gas hot water boiler increasingly suffered everybody pro-Lai. Adjustments for door ventilation ducts and flues, make sure the door is detailed and inseparable, knobs sure is handy, turned on and off label MUST be accurate. 3. Note the furnace to carry out inspection, inspection Security Council notes the situation is not good; the cock is not rotating flexible, convenient; all kinds of righteousness tables and handling equipment should be complete, fine, clean up. According to post-test, pressure gauge cocks should be in attitude. 4. The inspection system of process control. Boiler Biomass: Biomass vertical boilers, biomass boilers pillar. Biomass gas thermal oil heaters, biomass 5 mw steam boiler, biomass hot water boiler, biomass oil furnace. 5. inspection auxiliary facilities. Such energy conversion is steam boiler facilities, the kinetic energy of the oil in the heating furnace has a type of chemical energy, electromagnetic energy, heat energy, etc. smoke, and after converting furnace, must be provided externally output energy vapor, hot water, or inorganic heat carrier. 6. check combustion equipment, look at the ignition device is not a good situation; for the gear system, coal handling systems, ballast systems, brake test, no problem; Security Council spring gear box should be properly gripping and Moist; coal door right foot mark. Eagle iron neat detail, detail ballast plate, flexible pump power. 7. The auxiliary heating surface inspection, inspection aids (booster fans, pumps, etc.) coupled strong coupling; moderately loose belt; ample grease excellent; circulating cooling water smooth. According to the test, the protective cover mounting Security Council, an independent test run, deceleration always pay attention to an alternating current.
