The combustion efficiency increases with increased excess air - until the heat loss in the excess air is larger than the heat provided by more efficient combustion. Excess air to achieve highest possible efficiency for some common fuels: 5 - 10% for natural gas. 5 - 20% for fuel oil. 15 - 60% for coal.
Industrial boilers are closed vessels that use a fuel source or electricity to heat water or generate steam for industrial heating and humidification applications. The basic concept of a boiler involves a heat source (furnace) and a heat exchanger (pipes or tubes) or heat transfer medium which allows water to be heated above its boiling point.
The purpose of a boiler is to provide hot water or to generate steam. While it can boil fluid, is does not have to. The hot water or steam produced by a boiler can be used for many different applications in many different industries. These industries include food processing, laundry, brewing, building, sewer cleaning.
