Impact analysis and optimization of novel Arundo donax L.-coal co-firing on the operation of coal-fired power units
摘要
Abstract
Traditional biomass resources are rarely adopted by coal-fired power plants due to their seasonal availability and regional dispersion.A novel Arundo donax L.variety,characterized by high yield and robust adaptability to marginal lands such as tidal flats and coastal wetlands,offers a viable solution to these challenges.In this study,based on a 2×1 000 MW ultra-supercritical pressure once-through boiler,co-firing experiments of this novel Arundo donax L.were carried out,and its effects on thermal system,powder making system,and combustion characteristics of thermal power units were analyzed.The results show that the thermal power plant unit operation is stable after adding 15%Arundo donax L.particles.However,the stone coal discharge increases,the coal mill current is elevated by about 5%～10%,the maximum elevation of the coal mill inlet and outlet differential pressure is elevated by 10%～15%,the combustion intensity in the furnace decreases slightly.The low grindability index of Arundo donax L.is the key factor affecting the operation of the unit,and the study concludes that the torrefaction interval of about 250～300℃is the best interval to improve the grindability index of Arundo donax L.关键词
