摘　　要：通过对煤气炉通常的四种排渣现象的观察和分析,对其中炉温大大超过经典控制温度时,炉渣呈灰白色,含碳一般在10%以下,质松而脆,炉内蒸汽分解率、制气热效率也高的现象进行了合理的解释。提出了将操作区改在灰熔点(T_2)以上操作的建议。In this paper,the reasonable explanations are given out for that while the temperature of gas furnace is greatly higher than the traditional control temperature,the slag is white loose & brittle, containing less than 10% of carbon,and the high efficiency of steam decomposing and the high effi- ciency of heat for making gas,through abserving and analyzing the four kinds of common slags of gas furnace.Operation at the temperature above slag melting point(T_2)recommended.
