It has the advantages as following: small fluctuation controlling temperature, fuel conservation, so it has broad prospects of development and application.
由于它具有控制温度波动小、节约燃料等优点，具有广阔的开发应用前景。
2
It is believed that the quality change of material and fuel, especially the big reduction of coke thermal property, results in the furnace condition fluctuation.
认为原燃料质量变化，特别是人炉焦炭热性能的急剧下降，引发了炉况波动。
3
Because of there was advantages of little fluctuation for control temperature and saving fuel and so on, so this technique had worth of widely popularizing and application.
