煤粉予燃室是一种新型的煤粉燃烧方式。北京锅炉厂制造的 ＳＨＦ－２０／１３型锅炉在 采用煤粉予燃室后，锅炉炉膛体积热负荷高达 ２４０ｘ１０３［大卡／米３时］，锅炉外形尺寸大 为缩小，约可节省钢材３５％。 煤粉予燃室经过改进，采用了Ⅱ 、Ⅲ型予燃筒，３５°平面叶片旋流器并加装风粉均 匀板，在燃烧灰熔点高的烟煤时，已可连续运行１５天以上。试验研究说明煤粉予燃室 是可能很有前途的。 Pulverized coal combustion chamber is a new type of pulverized coal combustion. The SHF-20/13 boilers manufactured by Beijing Boiler Plant use pulverized coal to ignite the chamber, the boiler heat load volume up to 240x103 [Kcal / m 3 o'clock], the boiler greatly reduced size, saving about 35% . Pulverized coal to the combustion chamber has been improved, with Ⅱ, Ⅲ to the combustion cylinder, 35 ° plane blade swirler and the installation of wind powder uniform plate, burning high bituminous coal ash, it has been continuous operation for more than 15 days. Experimental studies show that pulverized coal combustion chamber may be very promising.
