Combustion Efficiency and Excess Air

May 12, 2006 · Based on the numbers posted the boiler is less efficient by 2 or 3 percent because the higher flue temperature means less heat is being transferred. The draft over the fire should be checked. Ideally it should be -.01"W.C. The O2 reading is also a little high 4-5% would be more ideal.

heat to the water in the boiler. A 4-pass design provides four opportunities for heat transfer. The stack temperature of a 4-pass boiler will be lower than the stack temperature of a 2 or 3-pass boiler, of the same basic design, operating under similar conditions. Because of this fact, the 4-pass will have higher efficiency and lower fuel cost.

Stack gas measurements indicate an excess air level of 44.9% with a flue gas minus combustion air temperature of 400°F. From the table, the boiler combustion efficiency is 78.2% (E1). Tuning the boiler reduces the excess air to 9.5% with a flue gas minus combustion air temperature of 300°F. The boiler combustion efficiency increases to 83.1% (E2).

Incineration is a waste treatment process that involves the combustion of organic substances contained in waste materials. Industrial plants for waste incineration are commonly referred to as waste-to-energy facilities. Incineration and other high-temperature waste treatment systems are described as "thermal treatment".Incineration of waste materials converts the waste into ash, flue gas and heat.

Monitoring Boiler Stack Temperature - Boiling Point - YouTube

normally, as the operating pressure increases, the stack temperature in a clean, well-tuned boiler will also increase, anywhere from 75 to 100 degrees over the saturated steam temperature. As an example, a 350-horsepower boiler burning natural gas, firing at , 10 psig operating, and with an 80 degree F ambient, will indicate a stack temperature of approximately 320 degrees F.
