Causes of large Resistance and insufficient Air supply in Oil-fired Hot Water Boiler systemThe hot water e 1 9 boiler system has great resistance and insufficient air supply: the reason is that the fuel particle size is mixed, the pulverized coal occupies the block coal gap, and when entering the grate, it is squeezed and dense by the gate, and the permeability is poor. First, the mass coal cannot be burned through, and there is still a red fire when the slag is discharged. Burn the slag blocking parts, slag carbon content is high; Second, coal leakage is serious; third, large resistance, increased blast, induced fan load, high power consumption. The furnace temperature is low, the coal quality is poor and the combustion condition is not good, the furnace temperature is low, sometimes even extinguishes, a large amount of unburned matter and ash powder blockage the economizer and air preheater, which causes the furnace to be in positive pressure combustion. Arrangement of part of reheater heating surface in hot water boiler In the region of higher smoke temperature, the heating area required by superheater is greatly increased. In order to reduce the flow resistance of the working fluid flow through the heater and increase the rigidity of the pipe, the superheater adopts a larger diameter pipe. In order to increase the ratio of radiation and heat absorption in the superheater system and make the steam temperature characteristics of the superheater steady, the radiant separator superheater and the semi-radiant rear screen superheater are arranged on the top of the boiler furnace. The separator superheater is arranged in the direction of furnace width, each of which is composed of a small screen, which not only increases the radiation heat transfer, but also prevents the rotating smoke flow to reduce the smoke in the width direction of the furnace into the superheater. The effect of temperature deviation.

"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 e 1 9 boilers 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. As of the end of November, this year's phase-out plan included 22 small businesses of 25 coal-fired boilers have completed 24 units, of which the use of special equipment to complete the cancellation of the registration certificate of 17.

City Commission by letter the person in charge, the next step, they will actively cooperate with relevant departments to intensify its efforts to strengthen the county has not yet out of the task of supervision and corporate efforts to accelerate the phase-out of the boiler has been using special equipment write-off registration certificate , guidance throughout the solid performance of the late acceptance procedures, and make due contributions to effectively improve the quality of atmospheric environment in Mianyang.
