Biomass gasification is a combined system of biomass dryer, gasifier and lime kiln, optimized for burning the product gas. After drying, bark or other wood residue is gasified in the CFB gasifier at high temperatures using a controlled amount of air. The resulting product gas is then burned in the lime kiln burner, which is optimized for product gas.
