『Abstract
This work presents the development situation of biomass gasification
power generation technology in China and analyzes the difficulty
and challenge in the development process. For China, a large agricultural
country with abundant biomass resources, the utilization of biomass
gasification power generation technology is of special importance,
because it can contribute to the electricity structure diversification
under the present coal-dominant electricity structure, ameliorate
the environmental impact, provide energy to electricity-scarce
regions and solve the problems facing agriculture. Up to now,
China has developed biomass gasification power generation plants
of different types and scales, including simple gas engine-based
power generation systems with capacity from several kW to 3 MW
and integrated gasification combined cycle systems with capacity
of more than 5 MW. In recent years, due to the rising cost of
biomass material, transportation, manpower, etc., the final cost
of biomass power generation has increased greatly, resulting in
a serious challenge in the Chinese electricity market even under
present preferential policy for biomass power price. However,
biomass gasification power generation technology is generally
in accord with the characteristics of biomass resources in China,
has relatively good adaptability and viability, and so has good
prospect in China in the future.
