烟囱是锅炉设备不可缺少的组成部分,有关它的设置的一些问题应予以足够的重视。锅炉的烟囱可导出燃烧反应的生成物,使释热过程得以继续不断地进行。它还可以产生排烟自然抽力,保持炉膛负压和减少引风机的功耗。强制通风的锅炉,烟囱主要作为烟气的扩散装置,使之达到环卫标准允许的程度。也有一些烟囱兼作水塔等建筑物支持之用。有时烟囱出了故障,对生产和安全的危害也是很大的。本文就小型锅炉烟囱的设置问题进行一些讨 The chimney is an indispensable part of boiler equipment, and some issues concerning its setting should be given sufficient attention. The chimney of the boiler can derive the products of the combustion reaction so that the heat releasing process can be continuously carried out. It can also generate natural exhaust smoke, maintain the furnace negative pressure and reduce induced draft fan power consumption. Forced ventilation boilers, chimneys mainly as a diffusion device of flue gas to make sanitation standards to allow the extent. Some chimneys double as water towers and other buildings support. Sometimes the chimney out of trouble, the harm to the production and safety is also great. This article discusses the setting of small boiler chimney
