摘要

【目的】传统生物质因季节性强、区域性分散等问题不被火电厂所采用。目前，一种新型芦竹不仅产量大而且极易生存，可种植于滩涂与沿海湿地等边际土地，能有效解决上述问题。【方法】基于2×1 000 MW超超临界机组直流锅炉，开展新型芦竹掺烧试验，分析其对火电机组热力系统、制粉系统、燃烧特性等方面的影响。【结果】结果表明：添加质量分数15%芦竹颗粒后，火电厂机组运行基本稳定；但石子煤排出增加，磨煤机电流提升约5%～10%，磨煤机进出口差压最高提升10%～15%，炉膛内燃烧强度有所下降；芦竹可磨指数低是制约机组运行的关键因素，提升芦竹可磨指数最佳烘焙区间为250～300℃。

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.
