Problems with atmospheric pressure heating furnaces
Thread Content
The heating furnace has been operating under overload conditions, with high temperatures of the superheated steam and exhaust gases. What are some solutions?
Cooling zero can! ` It’s impossible to be sure
A water injection line is added at the inlet of the superheated steam line to control the outlet temperature of the superheated steam. Enhance heat exchange between flue gas and air to reduce the flue gas temperature.
If the load can be reduced, then reduce it. Another approach is to start with the steam in the convection section and increase its amount; during the flue gas preheating phase, a rubber hose can be placed there to spray some water.
Since it’s an overload, the load needs to be reduced in order to address the problem at its root. The other options are not sustainable solutions. If the overload persists for a long time, all the components of the furnace will be damaged, significantly shortening the equipment’s service life
