Small businesses often use boilers to provide heat to their facility or as part of their industrial operation.  Boiler types include industrial, commercial, and institutional boilers which are subject to air quality regulations and requirements. 

Industrial boilers are used by heavy industry (e.g., metal and wood products manufacturing) to run processes or machinery or to produce heat or electricity. Most industrial boilers have a capacity between 10 and 250 million British thermal units (MMBtu/hr).

Commercial boilers are used by wholesale and retail trade, office buildings, hotels, and restaurants to supply steam and hot water for space heating. Commercial boilers are generally smaller than the industrial units with heat input capacities generally below 10 MMBtu/hr.

Institutional boilers are used in establishments such as medical centers, universities, schools, government buildings, and military installations to provide steam, hot water, and/or electricity. Institutional boiler systems are used for heating with hot water or steam. A majority of these are located at educational facilities and have heat input capacities generally below 10 MMBtu/hr.

Boilers can use a number of different fuels including coal (bituminous, sub bituminous, anthracite, lignite), fuel oil, natural gas, biomass (wood pellets or products), liquefied petroleum gas, and a variety of process gases and waste materials
