摘　　要：原煤仓是火力发电厂制粉系统中一个重要环节,原煤仓形式的选择直接影响到电厂的安全稳定运行。通过对常规原煤斗煤仓方案和双曲线煤斗、中心给料机煤仓方案的技术特点和技术经济的分析比较,提出中心给料机方案为较为有效的原煤仓防堵形式。Coal hopper is one of the most important facilities of coal pulverizing system in power plant. The design of the form and structural shape of coal hopper is essential to the safety and stabilization of power plant. By comparing the technical characteristics and technical economical index of coal hopper with central feeder, normal and double -curve coal hopper, coal bin central feeder is determined as the comparatively rational design scheme of coal hopper.
