Improve The Thermal Efficiency of Industrial Boilers

Dec 17, 2019 · At this time, the heat transfer efficiency of the boiler will be greatly reduced and the incomplete combustion loss will increase. Therefore, reasonable control of the air-fuel ratio, as far as possible to reduce exhaust heat loss and incomplete combustion loss, is another way to improve the thermal efficiency of boilers.

Understanding Oxygen Measurement in Flue Gas Streams

Jun 29, 2021 · When combustion is more difficult, the excess amount may need to be higher. For example, a pulverized-coal-fired boiler will run around 3 to 4% excess O 2, and a municipal solid waste boiler will be even higher, perhaps 5 to 7% excess O 2. Most gas- and oil-fired installations will be well below 3% excess O 2. Controlling combustion
