How to address the severe sulfidation problem in the convection chamber of delayed coking heaters from an operational perspective
Thread Content
Sulfurization crystals often form in the convection chamber of the heating furnace in our workshop. Besides ensuring that the components of the fuel gas meet the required standards, what other measures are needed during operation?
It is possible to consider installing a steam soot-blowing system in the convection section; such systems were used in older boilers, but have been replaced by shock wave and acoustic soot-blowing methods recently. In fact, if the steam is superheated, it works very well.
There are many reasons for the formation of sulfurized crystals in the convection chamber of the heating furnace; trying to increase the temperature of the convection chamber might help. Additionally, it is necessary to eliminate any areas in the furnace where steam leaks through
Reduce the sulfur content in the fuel and increase the temperature in the convection section.
The raw material issue is very difficult to resolve; measures must be taken, and steam purging is a good approach
Steam soot blowers used in soot blowing systems tend to produce sulfides more easily
