In the winter season, Fushun City, the town of Dongzhou District hada Liaoning Province, this ancient village is undergoing a transformation heating, core change is the use of "provinces" biomass based fuel like diesel boilers.

Yao is the inventor in "provinces" biomass boiler. He said, "provinces" boiler, that is, to save money, labor, and material. Combustion and conventional combustion boiler essentially different, are in the normal combustion surface of the fuel from the outside and inside, top-down combustion, using a strong wind, or take pulverized fuel, and other physical and chemical techniques, cause the fuel in the shortest rapid combustion of the time. "Provinces" boiler contrary, starting from the bottom of the combustion of solid fuels, from the bottom up, a minimum amount of intake air by controlling the slow combustion. In 2013, the innovative energy-saving combustion technology obtained national patent, and Chinese Academy of Sciences Institute of Engineering Thermophysics, experts Tsinghua University, Tianjin University and Harbin Institute of Technology as "domestic initiative, the leading domestic" and suggested in our rural north conduct a comprehensive promotion.

Yao said in the last year, Dongzhou District not only invest in the construction of "provinces" biomass boilers, but also the laying of underground pipe network 3500 meters, central heating ancient village 30 farmers.

We understand that in 2016, Fushun City, has more than 600 households will be "provinces" boiler for the production and life. 2018, Fushun City, the ancient village of straw as a pilot village central heating, promoting the use of "provinces" boiler.

"With the gradual popularization of rural straw central heating, greenhouses can pick Heating, sustained economic heating greenhouses; straw waste form the commercial mode of operation into treasure, straw harvesting, transportation, storage, processing, a new farmers' income channels; the sky bluer, the water clearer, more green mountains, beautiful environment will inevitably become a new growth point of the rural economy but to embark on a modern intensive production, road projects of market-oriented operation, there is still a way to go. . "in Yao she said.

The essay serve a documented basis for joint project of erection and operation of biomass residue firing CHP (Combined Heat and Power) unit. 58 tons/hour of steam at 12 barg are generated in few heavy oil firing based fuel like diesel boilerss and consumed in production process. The basic assumptions are that saw dust or/and wooden chips with LHV (Low Heating Value) 18,000 kJ/kg will be fired in a fluidized bed boiler producing about 30 ton/hour steam (about a half of needed process steam). The steam flow, passing through a back pressure turbine, will generate electricity corresponding to difference of enthalpies of fresh steam generated in the boiler and of one needed for process. From the turbine outlet the steam will be used, as today, for the technological process of the factory.

Fire fighting methods inventory based fuel like diesel boilers in the boiler use, if a fire phenomenon, you know how to deal with it? Today, Xiao Bian teach you the recipe. When coal is poor or low load, it may be administered less number, to maintain a high pulverized coal concentration, but can not chipping operation or asymmetric operation. Load is less than 170MW, should remain A, B powder layer to stable operation, when any failure to a powder, should be administered stable combustion, the failure to the powder to be put into operation, combustion stability, and then exit the gun run . Adjustment of the amount of the low-load air supply, to maintain the oxygen 4-5%, and adjust the opening degree of the auxiliary windshield. If it is a bad case of fire, may be appropriate to increase the primary air temperature, wind speed reduces time, but not overshoot the spark plugs burned once or blocked ducts. When the job should be strictly periodic system and to reduce powder powder switching system, dust bunker normal position at least 2.5 meters, so that a stable working state bunker, at each adjusting shutter powder to powder, the powder as far as possible amount consistent and stable, no spark plugs to prevent dust and to dust gravity caused by combustion fluctuations. Should maintain acceptable fineness of pulverized coal, according to chemical analysis, after adjusting the test plate to open Classifier, coal is poor or low load, it may be appropriate to increase the fineness of pulverized coal, in order to facilitate combustion. Maintain normal milling system, powder separator shall not clogging the tertiary air pinkish large deterioration in combustion. Furnace can eliminate air leakage and air leakage milling system, all view of the fire without plugging holes, play Giocondo, etc. should be tightly closed. Value of the long should keep abreast of the situation of coal and coal quality fuel, combustion instability occurs when, such as when a fault powder, coal mutation, the differential signal changes drum is too large, the oil should immediately cast coal combustion stability and taking samples for analysis. High load, the premise of ensuring steam temperature, combustion can be appropriately adjusted to prevent the shift of the center of the flame, so that the furnace exit gas temperature rise, caused by coking. Operator adjusting the main steam temperature may be employed with positive pagoda wind run, the central flame stabilizer. Should be a bellows pressure control as a basis for wind speed, in time to observe the duct pressure and temperature, the premise of ensuring primary air duct is not blocked, a bellows pressure should not exceed 4000Pa.

The fuel used in different types of oil and gas based fuel like diesel boilerss produced by ZG boiler will also vary.
