Abstract: Because Spartina contains plenty of minerals such as chlorine and kalium, it could cause slagging during gasification. The authors researched and developed gasification techniques and equipment which are suitable to transform Spartina into clean gas and realize gas-heat-electricity triple cogeneration. The techniques improved utilization ratio of gasification equipment and accessory system, and realized large-scale and industrial utilization of Spartina. Independent, integrated and integrative resource-energy-environment Spartina energy system can be established by gas-heat-electricity triple cogeneration technology. It can transform low-cost and low quality resource into high quality energy(gas, electricity, heat) to meet the local energy requirements.
