What is the operating principle of the gas ibr boiler steam trap valve model photo: With the national energy saving policies have been introduced, the traditional coal-fired industrial boilers gradually being replaced by gas-fired boiler, industrial power about a revolution in the field of energy saving and environmental protection are taking place. Many users of gas-fired boilers there are a lot of places do not understand, fast Boiler simple for everyone to explain some principles of operations on the gas boiler. 1, injected into the boiler furnace combustion head-mixed fuel and air, the combustion by the ignition device in the head of the full ignition gas furnace, a heating furnace to achieve a boiler, furnace tube effect. Generally begins, a good boiler, the combustion chamber can design a large capacity multi-curve, so that the heating area and stroke to increase the fuel in the furnace body, which can improve the thermal efficiency. Thus, the key gas-fired boiler combustion head, so that the air mixed gas and, after reaching a certain percentage in order to better enable complete combustion of fuel.
"Green Castle is the gold and silver mines," Mianyang City, Sichuan Province to respond positively to President Xi's philosophy of environmental protection, strengthen the construction of ecological civilization, and vigorously promote the city's air pollution control, focusing on small ibr boiler steam trap valve model photos county level and above cities out of coal, comprehensive enhance the transformation of 20 tons of steam / hour or more coal-fired boilers, let Mianzhou earth, the sky bluer, and more green, the water clearer.
In advance of the phase-out of coal-fired boilers, the city's focus on top-level design, in June this year issued a "county-level and above Mianyang urban area small coal-fired boilers work out program," clearly take demolition, renovation, clean energy alternatives and other measures , before the deadline to the end of March 2019, phasing out the county level and above urban area 10 steam tons / hour and the small coal-fired boilers (because of the promotion of cogeneration of small coal-fired central heating boiler replacement must be before the end of 2020 total phase-out). Not included in the program for the elimination of the objectives and tasks of various types of small coal-fired boilers, find an out of one.
Eliminate small coal-fired boilers for improving urban air quality has a positive effect. In Mianyang, a wine business one step ahead, we tasted the sweetness: switch to phase out coal-fired boiler gas boiler. Before coal-fired boilers, the company must invest a lot of money each year to buy coal used in the treatment of fly ash and slag above, and coal combustion will bring countless pollutants.
After starting gas fired boiler to boiler project, which began to corporate purchase and install a gas boiler, energy-saving cooking pot bottom, ice bucket, multi-cooler tube array, sewage tank 58 and other equipment (sets); and in 2017 December formally put into use. After coal to gas, coal storage area is no longer required, cinder storage area ,, new construction land for the enterprise, greatly reduce production operating costs. "
This year the city built-up area of the city's coal-fired boiler phase-out targets small task is 25 units. City Commission by letter, the Environmental Protection Agency, Bureau of Quality Supervision and other relevant departments to strengthen organizational leadership, establish long-term working mechanism, compaction work responsibilities, in close collaboration to promote the division of labor, and strengthen supervision to ask efficiency, strict examination and approval for the record, put an end to new coal-fired small boiler, strengthen propaganda and guidance, do a solid job of work to promote the service.
