How to reduce boiler heat loss
The difference between the total heat released by complete combustion of fuel in a boiler and the heat used in the boiler. It includes the heat carried away by boiler flue gas, the heat lost in the air around the furnace, the heat not released during fuel combustion or incomplete combustion, and the physical heat carried away by ash. These losses are expressed as the percentage of total heat released by complete combustion of the fuel.
Methods for reducing heat loss
Automatic combustion regulation is the regulation of fuel quantity under the premise of controlling the steam pressure at the outlet of the boiler to reach a certain value. In order to achieve reasonable combustion, it is necessary to control the combustion quality, control the ventilation system based on the oxygen content of the flue gas in the boiler exhaust, adjust the ventilation to maintain an appropriate amount of air excess coefficient, and reduce the heat loss of the boiler. Therefore, a complete combustion regulation actually includes boiler steam pressure regulation, combustion setting, combustion volume regulation, air volume regulation, furnace negative pressure regulation and drum control, and induced draft fan.
