中文摘要	介绍了清华大学新研制的一次煤粉浓缩加一次风预热自动控制装置组成的燃烧系统。该系统利用一次风管弯头来进行煤粉的浓淡分离 ,具有结构简单分离效果好的特点 ;通过温度的测量来控制预热调节门的开度实现对卷吸热烟气量的控制 ,能够适应不同煤种稳定着火的要求。利用该燃烧系统对丹东化纤股份有限公司热电厂的一台 15 0t/h的煤粉炉进行了改造并进行了 10个工况的运行实验 ,结果表明 ,该燃烧系统具有良好的煤种适应性和负荷调节性 ,在各种工况下可以保持燃烧稳定 ,并且燃烧效率高; A description is given of a combustion system newly developed by Tsinghua University, which comprises an automatic control unit for concentrating primary pulverized coal and preheating primary air. The combustion system utilizes a primary-air pipe bend to carry out dense/lean separation of the pulverized coal, and features a simple construction and good separation efficiency. Through temperature measurements it is possible to control the opening degree of a preheat-regulating valve, thus controlling the entrainment quantity of hot flue gases and achieving a stable ignition by adapting to various ranks of coal. By using the combustion system under discussion the retrofitting of a 150 t/h pulverized coal-fired boiler at the Thermal Power Plant of Dandong Chemical Fiber Co. Ltd. was implemented and operating tests at 10 different working conditions performed. Test results indicate that the combustion system can adapt well to various ranks of coal and to load variations. Under various operating conditions a stable combustion and high combustion efficiency can be attained.
