摘　　要：提高管式加热炉的热效率,减少燃料消耗,能够达到节能减排的目的。减少管式加热炉炉体散热损失是提高加热炉热效率的方法之一。以两种常用的典型炉型为例,进行了炉墙外壁温度经济性计算与分析,认为在现行设计标准的基础上降低炉墙外壁温度,减少加热炉散热损失,提高加热炉热效率是可行的,在多个炉墙外壁温度的比选中,按照3年收回增加的投资成本考虑,确认炉墙外壁温度为60℃最为经济合理。Increasing heat efficiency and decreasing fuel consumption can achieve the purpose of energy conservation and emission reduction.Reducing the wall temperature to decrease the heat loss of tubular heater is one of the way increasing heat efficiency.This article takes two typical kinds of heater as an example,calculates the quantity of heat loss and lining under the different wall temperature,and discusses the economic condition.It is considered that reducing the wall temperature can decrease heat loss and increase heat efficiency on the basis of the current design standard,and 60 ℃ is the most economic condition during the three years payout period.
