【摘要】 富拉尔基发电总厂1号～4号炉均已成功地改造安装了自动可调叶栅煤粉分配器。此分配器能在运行中对空气和煤粉分配进行调节,实现了风粉分配由不可控制到有效控制,有效调整炉膛出口温度,避免或减轻炉内结渣,使锅炉的低负荷不投油稳燃能力得到大大增强,并且由于燃料在炉内燃烧被分为过浓燃烧和过淡燃烧两部分,使NOx排放量低于373mg/m3,机械不完全燃烧损失降低了1.166%,具有良好的经济效益和社会效益。更多还原

【Abstract】 Fulaerji Power Plant General Works has successfully modified and installed for boilers No.3 and No.4 a pulverized-coal distribution device fitted with auto-adjustable cascades. By using this device it is possible to regulate the distribution of air and pulverized coal during boiler operation, thus realizing the effective control of pulverized coal distribution. As a result, the furnace outlet temperature can be properly adjusted to eliminate or alleviate slag formation in the boiler. This in turn can greatly enhance the ability of the boilers to maintain a stable combustion at low loads without resorting to oil firing. Moreover, as the fuel during its combustion in the furnace is divided into two portions, namely, excessive thick and excessive thin, good economic and social benefits can be attained with NO_x emissions being lowered to less than 37.3 mg/m 3 and mechanical incomplete combustion loss reduced by 1.166%.更多还原
