Conditions To Ensure Good Combustion In A Steam Boiler

Combustion Air - an overview | ScienceDirect Topics

Combustion air is drawn from the waste storage area for two reasons. First, it maintains a negative draft in the tipping area, preventing litter and odor from escaping the building. It also destroys the odor by exposing it to the high temperatures in the furnace. Underfire air is frequently preheated using steam

Boiler Energy Efficiency Measures

2020-7-13 · Thus high boiler outlet exhaust gas temperature could be a good indication of such fouled conditions. To remedy the case, maintenance practices should include boiler's soot blowing, de-scaling, good water, combustion adjustments (to reduce soot formation) and son on. For this purpose, the heat transfer areas of the boiler must be monitored.
