针对北京某公司一台蓄热式加热炉因烧嘴排烟不畅而导致加热炉内压力升高问题进行了分析研究。为了维持加热炉内微负压的状态,改变了烧嘴的结构尺寸,确定了烧嘴空气进口处需要提供的压力。并通过分析确定了烧嘴空气进口处所加挡板的厚度。 A Beijing-based company for a regenerative heating furnace due to poor smoke exhaust furnace caused by the problem of increased pressure in the furnace were analyzed. In order to maintain the state of micro-negative pressure in the heating furnace, changing the size of the burner structure, to determine the pressure required to provide the burner air inlet. And through the analysis to determine the burner air inlet baffle thickness added.
