POWERMAX Rice Husk Gasification Power Plant
The POWERMAX rice husk biomass gasification power generation system (BGPS) converts rice husk (also called rice hull) into combustible gas, which is then used as fuel in a gas engine to generate electricity. Biomass gasification overcomes key disadvantages of rice husk, such as low flammability and inconsistent quality. With a small footprint and environmentally friendly operation, it is one of the most efficient ways to utilize biomass for power generation.
Key Requirement for Rice Husk Fuel
To ensure optimal performance in the rice husk gasification power plant, the moisture content of the rice husk must be less than 20%.
How the Rice Husk Gasification Power Plant Works
The process consists of three main steps:
- Biomass gasification – Rice husk is converted into syngas in the gasifier.
- Syngas purification – The raw gas passes through a purification system that removes dust, tar, and other contaminants to protect the gas engine.
- Power generation – The clean gas fuels a gas engine to produce electricity. Waste heat from the engine can be recovered for steam or hot water, and a combined cycle with a steam turbine can further increase overall efficiency.
Technology & System Models
POWERMAX offers modular rice husk gasification power generation systems covering capacities from 50 kW to 20 MW, with two main series designed specifically for rice husk:
- CFBG Series (Circulating Fluidized Bed Gasifier) – Suitable for 200 kW to 2000 kW applications. It accepts rice husk with moisture ≤20% and particle size ≤8–15 mm, delivering a gas calorific value of 1200–1300 kcal/Nm³.
- DFBG Series (Downdraft Fixed Bed Gasifier) – Ranges from 50 kW to 1000 kW. Requires rice husk moisture ≤16% and particle size less than 1 cm, producing syngas with a calorific value ≥1100 kcal/Nm³.
Both series integrate high‑efficiency generator sets (500–1000 rpm or 1500 rpm) equipped with Siemens alternators and advanced European engine control systems. Compared to conventional boiler‑fired systems, POWERMAX biomass gasification plants deliver a highly competitive solution for reliable rice husk electricity generation.
