Abstract

The biomass gasification coupled power generation project of a power plant is the first biomass gasification and coal-fired coupled power generation project using agricultural and forestry biomass residues as the main fuel in China, and has completed 72+24 hours of full load test run in September 2018. With the formulation of relevant standards, in order to further improve the overall operational capacity of the project, and give full play to the demonstration significance of the national coal-fired coupling power generation technology transformation pilot project, scientific and technological research has been carried out in such aspects as electricity metering. By upgrading the electricity metering system, on the one hand, it can meet the latest technical requirements of the electric power industry standard “Coal fired coupled biomass power generation biomass energy calculation Part 1: Agricultural and forestry waste gasification coupling”, on the other hand, it can solve the problems encountered in existing equipment such as short operation time, large maintenance volume, and low accuracy of gas composition detection, improving equipment stability, while reducing heat value loss, and reducing production costs, Improve production efficiency.At the same time, after the heat value analyzer is changed, the measured heat value loss is reduced by 20%. Based on the annual utilization hours of the gasifier, about 6400 tons of biomass fuel loss can be recovered in one year, and the annual fuel cost recovered is about 2.56 million yuan.
