Biomass gasification power generation technology, also known as biomass power generation systems, simply said, is a variety of low calorific value solid biomass energy resources, such as agricultural and forestry waste, organic waste through gasification conversion of biomass gas, purification, cooling after entering the gas turbine power generation technology.
Our company produces biomass stalk gasification furnace equipment is the most advanced equipment in the domestic market, the use of the most advanced gasification technology, the technology in the peer is also the first domestic. Compared with the existing similar products, its structure is more scientific, the performance is superior, the technology is more advanced. The calorific value of combustible gas production up to calories, can directly replace other combustible gas for industrial gas. In the aspect of environmental protection, the operation of the whole equipment without any sewage generated, completely avoid the secondary pollution of water; using new type catalyst, the complete elimination of the tar yield, no black smoke emission in the whole production process, flue gas emission standards higher than national standards. In terms of intellectual property, the company’s R & D team to master the core technology of the equipment, with independent intellectual property rights, access to a number of independent research and development patents. The equipment price is reasonable, the investment income is quite good, the short-term can recover the cost, has the very high promotion application prospect. The biomass waste raw material is converted into biomass combustible gas, which has the advantages of high gas cleaning, high utilization rate, convenient transportation and convenient combustion. The reduction of environmental pollution by biomass energy, which is conducive to the survival of the human environment, is an imperative measure.
Two, biomass gasification furnace equipment process
Biomass gasification furnace equipment comprises a feeding system, a gasification system and a control system. After the raw material is dried (water content less than 5%), the raw material is conveyed through the advanced automatic feeding device to the reactor feed inlet through the spraying device. Under a certain thermodynamic condition, the fuel gas and tar can be produced by the rapid pyrolysis and gasification of the heat carrier gas and catalyst in the reactor. After the gasification, the catalyst and the carbon slag are conveyed to the regenerative furnace through the automatic feeding device, and the catalyst is heated by the high temperature, so that the catalyst is regenerated and returned to the reactor for gasification. The catalyst is continuously heated and recycled, and the heat efficiency of the gas is improved.
Gasified gas. After multi-stage dust removal, removal of coke, cooling the gas that can be directly used clean combustible gas. The composition of combustible gas contains CO, H2 and CH4, the calorific value of gas is as high as Kcal/Nm3.

Construction of large and medium sized biomass gas power station. For internal combustion engine power generation, steam turbine power generation.
1, cost analysis
Biomass gasification power plant is the main cost of biomass fuel, labor costs, supplies, equipment maintenance, etc.. The local biomass fuels (such as straw) 200 yuan / tons of calculation, running 8000 hours in, comprehensive and direct operation cost is 0.42 yuan / degrees (equipment depreciation to 15 years), the annual profit 341.62 million yuan, investment recovery period is 1.33 years. The specific cost of power generation is as follows:
1.1 fuel costs
Power plant annual biomass (such as straw): 10, 000 tons, the acquisition price of 200 yuan / ton, the cost of biomass straw: 1.3 x 200=260 million / year;
1.2 sales revenue
KW power plant in 8000 hours, the total power generation 8 million degrees, the government purchase price of 0.75 yuan, the total income: 6 million yuan / year ( kwh electricity X 8000 hours / year X0.75);
1.3 biomass ash income
Biomass straw ash income:
Annual output of straw ash: tons of straw
Power plant straw ash income: 520 thousand yuan (yuan per ton x 200 yuan / ton)
1.4 biomass tar income
Annual production capacity of 390 tons of tar
Power plant annual tar income: $390 (tons x 1500 yuan / ton)
1.5 material expenses
Material cost: oil, water and so on, every year for the;
1.6 depreciation cost
Depreciation and amortization expenses: equipment, a total investment of 500 million yuan, fixed assets according to 15 year amortization, the residual rate is only 5%, and the rate of amortization was 6.67%. Depreciation expense and amortization expense: $.
1.7 maintenance cost
