Description
Technical field
The present invention relates to the technical fields of heating equipment transformation, solid at electric heating more particularly, to a kind of coal-fired boiler reform
The method of body heat storage boiler.
Background technique
Coal-burning boiler refers to the boiler to burn using coal as fuel, and coal becomes heat after furnace chamber inner combustion, by cold water
Water, with for people to use.Coal-burning boiler mainly has burning drinking water boiler, heating and the bathing of supply boiled water according to purpose classification
Burning hot-water boiler, supply steam coal-fired steam boiler, boiling and the coal burning heat-conducting oil of drying boiler, above-mentioned several boilers
Have wide range of applications, long service life, operating cost is cheap, and many conveniences are provided for people's lives.However, coal-fired
The fuel of boiler is mainly solid fuel coal, and coal exists during burning and burns insufficient and reduce coal-fired pot
The thermal efficiency of furnace, and coal can generate a large amount of flue dust, sulphur and nitrogen oxide after combustion, and these noxious gas emissions arrive
In atmosphere serious harm can be caused to human lives and ecological environment.For this purpose, people install coaling system in boiler, so that
Coal burning more sufficiently, greatly improve the thermal efficiency of coal-burning boiler, meanwhile, it is de- that desulfurization also has been carried out to pernicious gas
Nitre processing, dedirt processing effectively avoid the harmful gas of discharge so that the flue gas of discharge reaches the discharge standard of environmental protection administration
Body.But it is needed coal grinding using above-mentioned coaling system into powder, and the process handled pernicious gas is more multiple
It is miscellaneous, it is also not easy to manage in operational process, also consumes a large amount of cost of investment, therefore the effect is unsatisfactory.It is sent out according to country
Exhibition reform committee, Environmental Protection Department, the Ministry of Finance, State General Administration for Quality Supervision, the Ministry of Industry and Information Technology, pipe office, state, National Energy Board in
" coal-burning boiler energy-saving Environmental-protection comprehensive promotes engineering construction scheme " issued in by the end of October, 2014, implementation content is required in Urban Thermal
Small-sized dispersion coal-burning boiler is eliminated in solenoid net overlay area, quickening, carries out concentrated supply of heating in the city, gradually forbids producing and using hand
Burning boiler and other backwardness type of furnaces, eliminate and fall behind coal-burning boiler, therefore, cause largely idle coal-burning boiler.
In view of the above-mentioned problems, people by coal-fired boiler reform at oil burning boiler, by coal-fired boiler reform at gas fired-boiler, or
Person is by coal-fired boiler reform at biomass boiler.Oil burning boiler primary combustion diesel oil, machine oil, kerosene, can be improved efficiency of combustion,
But the discharge of carbon dioxide and sulfide etc. still can be generated, further, since easily being led into water and air in oil burning boiler oil pipe
Cause is gone wrong frequently, and fuel oil transportation, the risk of storage are high, accident easily occur, need significant care.Gas fired-boiler it is main
Fuel is combustion gas, can be divided into natural gas boiler, town gas boiler, Coke-oven Gas Boiler, liquefied petroleum steam pot according to fuel
Furnace and methane boiler, using gas fired-boiler can full combustion fuel, thermal efficiency utilization rate is high, and the operational safety of boiler is stablized,
But gas fired-boiler is in the process of running, since water is burnt sky in improper, gas pipeline leakage of lighting a fire, misoperation, burner hearth
Etc. reasons, it may appear that explosion accident, explosion time, mainly furnace implosion be fried or entire Explosion of boiler proper.Biomass boiler refers to
Using biomass energy as the boiler of fuel, the energy mostlys come from organic substance, plant or the excrement of animal, using biology
Matter boiler keeps the space of burner hearth bigger, and internal structure makes the more abundant of biomass fuel combustion, additionally it is possible to avoid discharge sulphur
It is polluted caused by compound, still, fuel still can generate carbon dioxide gas during burning, so that ozone layer is destroyed,
Greenhouse effects are exacerbated, in addition, biomass boiler is also easy to slagging during burning, increase the maintenance in boiler operatiopn
The workload of cost and maintenance, and when boiler scaling is serious, can also force biomass boiler to reduce load operation, eventually by
Compel blowing out.
Summary of the invention
The purpose of the present invention is to provide a kind of coal-fired boiler reforms into the method for electric heating solid heat storage boiler, to solve
Existing in the prior art, for coal-fired boiler reform at oil burning boiler, discharge smoke pollution is big, and transports and store the mistake of fuel
Cheng Zhong, safety are low；Coal-fired boiler reform is easy to happen explosion at gas fired-boiler；Coal-fired boiler reform holds at biomass boiler
