gas fired 4 ton steam boiler

Gas pressure hot water boiler pressure introduction gas hot water boiler: gas pressure hot water boiler pressure vessel belongs, as always pressure hot water boiler is full of water, so no water level, but to be fitted with pressure gauges, safety valves and thermometers. Circulating pump pressure hot water boiler heating system is generally used in water pump, which is pumping systems engineering backwater sent to the boiler, it is necessary to overcome the resistance of the systemic circulation, but also to maintain a certain pressure boilers, hot water does not guarantee high temperature vaporization . Pressure hot water boiler can not only supply low-temperature water, but also to supply hot water Features: 1, boiler design, manufacturing, supervision and inspection are strictly according to "hot water boiler Safety Supervision" ensure long-term security and stability of the boilers. 2, the boiler body is a shell type three return all wet back downstream pyrotechnic pipe structure, large combustion flame in combustion chamber a slight positive pressure, combustion heat load is low, less NOx emissions of harmful substances. Through advanced machine test bed to test several times to verify the boiler under various load operation can get good thermal performance, qualified flue gas emissions targets as well as a wide range of burner adapter. 3, before and after the boiler smoke box with a special heat insulation materials, high temperature, low thermal conductivity, good anti-radical quenching heat capacity, greatly extending the life of the smoke box. A lower smoke box is provided with a condensate drain, water condensed reduce corrosion of the pressure receiving member. 4, the boiler and each pot spout means disposed reasonable to optimize the pot water circulation, prevent scale generation, but also help to improve the water side heat transfer. Set hand hole, inspection hole in the poor circulation of weak links, to facilitate regular inspection and maintenance. 5, the temperature of the boiler smoke box structure compared to dry wet back boiler back, greatly reduced, the smoke box solves the frequent need to maintain the operation of the phenomenon; 6, a large volume of water boiler design, the load fluctuation of furnace not sensitive to large changes in the load range of users still apply. 7, industrial boilers professional artists and designers carefully designed appearance, novel and unique and yet with the surrounding environment coordination. Sino-Swiss boiler completely changed the image of heavy industrial boilers, industrial boilers is a new concept of low-carbon twenty-first century. Construction and installation points: 1 explosion-proof door is provided on the fuel, the rear of the gas-fired boiler or pipe smoke, explosion door location should be conducive to explosion venting. For gas explosion likely to endanger the safety of the operator occasions, should be installed on the guide tube pressure relief blast doors. 2. Installation of boiler and its auxiliary equipment, water treatment equipment should meet the technical requirements of the device manufacturer. Equipment foundation must be the arrival of equipment and after verification and design drawings before construction. 3. When mounting the device, the device should be avoided, to install the floor material are collected together. Column using a construction, the beam lifting device, must first verify that the carrying capacity of the beam, the column. 4. After the pressure test acceptance oil, gas, water, steam pipe installation, according to "Industrial metallic pipeline construction and acceptance" in GB50235-1997. The main construction practices and node configuration detail see National Building Standard Design Atlas. 02R110 "Gas (oil) boiler room engineering design and construction Atlas" 02R111 "small vertical, horizontal tank Atlas" 02R112 "Tank dome Atlas"

Gas-fired fired 4 ton steam boiler is an advantage on the device using an environmentally friendly energy-saving: With the designers re-design of mechanical innovation, simple and easy to operate equipment, gas steam boiler is not only relatively simple, and better ensure the safe operation of ; saving advantages: high-temperature low-pressure gas steam boiler with a characteristic greatly reduces the stress levels of heating equipment, less direct advantage is the reduction in equipment investment. Electric heating boiler and the boiler is mainly composed of electric control box and control system. Its characteristics are environmentally friendly, clean, no pollution, no noise, automatic, with limited energy and reduce prices significantly, as a new boiler electric heating boiler equipment increasingly being recognized. Electric heating the core member is electrically heated boiler, directly determines the life of the boiler, to select a non-metallic electrical heating tube (such as a ceramic heating pipe), because it is resistant to the load, a long life, and a water separation structure, the boiler Wing no leakage. Fuel gas boiler is not only fuel but also refers to the gas boiler. Previously no such dual-fuel boiler, burner because either fuel or gas, no dual fuel burners. With the rapid development of the world energy equipment, some European countries begin production and sales of fuel gas burner, dual fuel burner and boiler combination of organic birth of a new breed of boiler - fuel gas-fired boiler. It was also said that the proportion of contact with air, just the right amount of fuel and the amount of combustion air composition in order to achieve combustion efficiency, but also reduce gas emissions and achieve energy-saving dual, very convenient. Gas steam boiler may be configured according to the actual amount of steam required, thus reducing waste of energy. The higher the degree of matching the actual demand and supply theory, better energy-saving effect. Continuous sewage heat can be utilized by a heat exchanger, thereby increasing the water temperature deoxygenated water. Gas-fired steam boilers and other machinery and equipment, more in line with current environmental requirements, so it has been widely used.

The reason you need to know the boiler energy consumption (reheat steam temperature) reheat steam temperature problems 1. Circumstances reheat temperature rises 1.1 Move boiler furnace flame center, furnace outlet temperature increases (see main economic indicators No. 5 boiler exhaust gas temperature). 1.2 coal increased too fast. 1.3 Excess air amount is increased. 1.4 pulverizing system start-stop. 1.5 Automatic control of the reheater desuperheating water improper adjustment. 1.6 reheater sootblowing time poor choice. 1.7 feed water temperature is low. 1.8 the high pressure turbine exhaust temperature is high. Next to the 1.9 high leakage, high reheater inlet temperature. Hot and cold extraction section greater then 1.10. 1.11 boiler heating surface design is unreasonable, over-temperature reheater tube wall, forced cooling operation. 2. Reheat the following partial flame temperature is lowered center 2.1: burner tilt deviation, hem; burner is switched from the upper to the lower layer, the lower layer or to an excessive amount of the powder; volatile coal fraction is increased, the pulverized coal thinning, water reduction. 2.2 reheater heating surface fouling, slagging, fouling the interior. 2.3 Save reheat the heated drain valve. 2.4 automatic adjustment inappropriate, excessive reheater desuperheating water. 2.5 feedwater temperature. 2.6 economizer and water wall sootblowing time poor choice. 2.7 reduce the amount of coal too fast. 2.8 # 1, # 2 high pressure heater is disabled, increasing the reheated steam flow.

Fangkuai Boiler is a clean-up boiler equipment based on various excellent scientific and technological advancements, focusing on product development, manufacturing, and manufacturing that are more efficient, environmentally friendly, and energy saving, and meet the basic national conditions of environmental protection in China. In order to promote the rapid development of the heating furnace manufacturing industry, people-oriented, consider the specific requirements of customers in the manufacturing industry for heating furnaces in various industries.
