Description
Technical field
The utility model relates to the Biomass Energy Utilization technical field, especially a kind of biomass molding fuel and coal multifuel combustion power generating equipment.
Background technique
The research and development of biomass energy have become one of global heat subject, in the application process of biomass fuel, having only powdery living beings and coal to be blended in fluidized combustion or biomass molding fuel burns in the special-purpose stove of biomass molding fuel, do not burn in the grate firing boiler and have biomass molding fuel and coal to be blended in, this mode will become the important method that biomass molding fuel is widely applied.
The model utility content
The purpose of this utility model is to provide a kind of biomass molding fuel and coal multifuel combustion power generating equipment, can will generate electricity after biomass molding fuel and the coal mixed combustion.
The technical solution of the utility model is: a kind of biomass molding fuel and coal multifuel combustion power generating equipment, comprise grate firing boiler, the steam outlet of described grate firing boiler is connected with steam turbine by pipeline, this steam turbine and generator are in transmission connection, and the steam (vapor) outlet of gas-turbine is connected on the water intake of grate firing boiler through condenser, condensate pump, oxygen-eliminating device, high-pressure heater by pipeline.
Also be provided with exhaust tube on the described steam turbine to high-pressure heater, oxygen-eliminating device heat supply gas.
Described oxygen-eliminating device is provided with make-up pipe.
Be connected with the condensed water Circulation pipe that drives by circulating water pump on the described condenser.
The utility model in use, biomass compact fuel and coal multifuel combustion can be alleviated the conventional energy resource resource and face deficient pressure, the outlet fluid properties of biomass compact fuel and coal multi-fuel fired boiler can reach the standard of coal fired boiler substantially, put before this again, utilize biomass compact fuel and coal multifuel combustion Processes and apparatus, can save 1/3 fire coal at least; The industrial biomass compact fuel that utilizes in a large number will have conclusive effect, biomass energy NO to solving atmospheric pollution
xDischarge amount is well below conventional energy resource, and CO
2Discharge amount be zero, but living beings directly burning energy dissipation is hugely arranged, commercial Application can improve the combustion parameter of biomass compact fuel, reduces the loss of energy to the full extent.
