What are the characteristics of biomass gasification power generation technology?
(1) The system supply and power station construction cycle is short, and the general contract signing to power station operation time is 4-6 months;
(2) Low total investment in power plants (including equipment, civil engineering, and installation)
(3) The system has sufficient flexibility and simplicity. Due to its composition of a biomass gasification furnace and a gas internal combustion engine (spark plug ignition), the special energy biomass gasification power generation system can be opened and closed at any time, with short startup and shutdown time, low requirements for operators, and low operating and maintenance costs
(4) The system has good cleanliness, and biomass itself is a renewable energy source, which can effectively reduce the emissions of harmful gases such as CO2 and SO2. However, the gasification process usually has a lower temperature (around 700-900 ℃) and a low amount of NOx generation, which can effectively control NOx emissions
(5) The system has high economic efficiency, and the flexibility of biomass gasification power generation system can ensure the effective and good economic efficiency of the technology on a small scale. At the same time, the gas power generation process is simple and the equipment is compact, which also makes the investment of biomass gasification power generation technology smaller than other renewable energy power generation technologies. Therefore, overall, biomass gasification power generation technology is the more economical power generation technology among all renewable energy technologies.
(6) Compared to solar power generation, wind power generation, and hydropower generation, biomass power generation systems can generate 7200-8000 hours of electricity annually with sufficient biomass energy, resulting in faster investment returns
(7) High utilization efficiency and economic benefits of gasification by-products: gas-phase products (combustible gas) are used for power generation, gas supply, and replacement of coal; The hot water produced during the gasification process can be used to provide hot water for bathing or several types of heating, and the liquid phase products (straw vinegar) can be used to prepare leaf fertilizer, deodorants, etc; Solid phase products (biomass charcoal) can be made into carbon based fertilizers, activated carbon, barbecue charcoal, etc;
