Biomass gas is a combustible gas produced by the pyrolysis or gasification of biomass at high temperatures, using materials containing biomass such as crop straw, forest waste, edible mushroom residue, livestock manure, and sewage sludge as raw materials. Biomass gas contains 15.27% hydrogen, 3.12% oxygen, 56.22% nitrogen, 1.57% methane, 9.76% carbon monoxide, 13.75% carbon dioxide, 0.10% ethylene, 0.13% ethane, 0.03% propane, and 0.05% propylene.

Biomass gasification power generation technology refers to the process where biomass is converted into gaseous fuel within a gasifier. After purification, this fuel is directly fed into a gas turbine for combustion, driving the turbine to generate electricity. The gas produced from biomass gasification contains impurities such as ash, carbon deposits, and tar. These impurities must be removed through a purification system to ensure the normal operation of the power generation equipment.

The Watt Biomass Gas Power Generation Unit in Jinan, Шаньдун, incorporates industry-leading technologies such as gas combustion control and electronic control mixers. It automatically regulates the air-fuel ratio, featuring safety, reliability, high thermal efficiency, cost-effectiveness, and fully automated operation management. This straw-based gas power generation unit operates stably, is simple to operate, and boasts a high degree of automation. It balances economic benefits with environmental requirements while exhibiting minimal raw material constraints, capable of utilizing rice husks, straw, wood chips, wood shavings, coconut shells, palm shells, corn stalks, corn cobs, flax stalks, sugarcane bagasse, mango pits, peanut shells, and other agricultural and forestry waste materials for efficient power generation. This series can replace imported products, with overall technology at the forefront domestically.

Our factory can configure single-unit power ranging from 100KW to 800KW based on customer requirements. For projects exceeding 1MW installed capacity, we recommend using multiple 500KW units in parallel grid connection for optimal cost-effectiveness. This configuration ensures more stable power plant operation, easier maintenance, and lower upkeep costs.

The biomass gasification power generation system comprises five components: 1. Gasifier; 2. Gas purification system; 3. Carbon removal system; 4. Power generation system; 5. Equipment control system. The principle involves high-temperature anaerobic combustion of feedstock in the gasifier to produce combustible gas (with a calorific value exceeding 1000 kcal). This combustible gas passes through a cyclone separator, wet purification equipment (dry purification systems used in some regions), gas-liquid separation equipment, and electrostatic precipitators to purify and cool the gas below 40°C. It then enters the gas generator set for power generation. Carbon residue from gasified rice husks can be recovered via a carbon powder collection device. The entire system operates without manual intervention. Feed and discharge processes are controlled from the control room, with real-time monitoring and periodic recording of temperature, pressure, and gas composition.
