What is the normal operating temperature of the outer wall of the heating furnace? It mainly refers to the heating furnaces in hydrorefining units and delayed coking units
Do you mean the part that is exposed to the air? At least it can’t be hot enough to burn people!
It’s all in accordance with the regulations set out in industrial boiler standards; the temperature shouldn’t exceed 50 degrees, right?
The construction acceptance specifications for industrial furnaces stipulate that the temperature outside the insulation layer shall not exceed 50 degrees.
It doesn’t exceed 50 degrees, and it’s not hot to the touch.
To reduce heat loss from the furnace walls of the radiant and convection chambers in heating furnaces, API560 or ISO17951-2003 \"Code for the Design of General Flame Heating Furnaces\" stipulate that, under conditions of an external temperature of 27°C and no wind, the temperature of the furnace body and the outer walls of the air preheater should not exceed 82°C, while the temperature at the furnace bottom should not exceed 91°C.
