以煤为直接烧料的炉窑,在燃烧过程中不仅存在烟尘污染而且燃料浪费严重,操作条件恶劣,加热质量不佳。因此,采用标准煤气炉,建立供应煤气站,虽可同时为许多炉窑提供煤气,解决环境污染等问题,且使用也较方便。但这种煤气站的投资大,要使用中小块度优质煤。这对缺乏优质煤供应的中小单位自建正规煤气炉是困难的。简易半水煤气炉虽存在使用起来不如正规煤气站那样方使等缺点,但在使用它产生的热煤气时,煤气和焦油的物理热、焦油和部分粉粒 Coal directly fired furnace, in the combustion process not only exist soot pollution and serious fuel waste, poor operating conditions, poor heating quality. Therefore, the use of a standard gas stove, the establishment of gas supply station, although it can provide gas for many furnaces to address environmental pollution and other issues, and more convenient to use. However, this gas station investment, to use small and medium-sized high-quality coal. It is difficult for self-built regular gas furnaces for small and medium-sized units lacking high-quality coal supply. Simple semi-water gas furnaces, although not as good as regular gas stations, have disadvantages such as physical heat, tar and some particles of gas and tar when using the hot gases it produces
