Technical field
This technology belongs to technical field of power generation, and in particular to a kind of biomass power generation system.
Background technology
Currently, traditional generation mode mainly has water power and thermoelectricity, since water resource is less, it can be used for the river of power generation
Less, it and needs to build a dam, improves water and apply drop, energization conversion, and in the downstream in power station, four seasons flow can be because building
Dam and reduce, be unfavorable for the ecological balance.Since the water level of areal Various Seasonal is different, spring and summer water level is higher, power generation
Amount is sufficient, and autumn and winter water level reduces, lower power production, or even cannot meet normal electricity consumption amount demand.
Thermoelectricity is that generated energy is not influenced by the four seasons as conventional Power Generation Mode, can be opened according to the real-time requirement of electricity consumption
Generating set is opened, different electricity consumptions are met.But when being generated electricity with coal, because containing the oxidations such as a large amount of N, P, S in tail gas
Gas increases in air solid particulate matter content, serious crisis health in PM10, PM2.5 and air, destroys ecological ring
Border.Also, coal resources are limited, and the regeneration period is long, and coal resources national at present are depleted, are bound to find new
Generation mode substitutes traditional energy.
Present some areas are introduced using wind-powered electricity generation as the generation of electricity by new energy of representative, assembling on meagrely-populated high mountain,
Wind turbine rotation is driven by natural wind, electric energy is transformed wind energy into, realizes the utilization of clean energy resource.But Various Seasonal, wind speed
Different, generated energy can also be affected, also, due to the limited energy that wind-power electricity generation can supply, can only meet small model
Residential electricity consumption demand is enclosed, because without generalization.
Solar power generation also receives favor, but the place that can only be grown in the sunshine-duration uses, and solar panel
In production process, the pollution of generation be it is very serious, thus, solar power generation do not have objectively yet promote and apply can
Row.

Technical solution using the present invention：Using the biomass power generation system, using plant residue as fuel, after crops is received,
Crops are transported power plant, hearth combustion is transported to after broken, burner hearth screen formula overheated steam pipe is heated, high pressure is utilized
Superheated steam red switch steam turbine, steam turbine drive generator, to realize power generation.Crops in combustion, allow in burner hearth
Fuel oil and secondary hot-air are sprayed into, crops particle is promoted fully to burn in burner hearth；Ashes after burning, pass through lower furnace portion
Ash bucket discharge, can be used as organic fertilizer raw material.To realize that the conversion of the Multi-class propagation and energy of substance uses, it effectively prevent
Environmental pollution.
China is very large in area and thickly populated, as a large agricultural country, can all generate a large amount of agricultural crop straw every year, and many areas are straight
It connects crop straw burning, causes to cause serious haze weather, the life and health of serious crisis people.If by these agricultural crop straws
It puts together, is transported to biomass power plant, be used to generate electricity after broken, it is dirty can both to have reduced the environment brought by crop straw burning
Dye can also realize the multistage conversion of energy and clean utilization, at the same time it can also increase the income of peasant, realize three offices won
Face.
Using the technical solution, since tail gas then is mainly based on carbon dioxide, pollution can't be brought to air,
Then the ashes after can be used as organic fertilizer raw material, realize recycling for substance again, thus, as a kind of novel green
The biomass power generation mode of cycle has preferable promotion prospect and social benefit.
In addition, the system, relative to traditional coal power plant, equipment greatly reduces, burning is abundant, need not also be installed as
Phase processing equipment reduces the operation expense of generating set, increases economic efficiency.
