Controlling Air Pollution from Boilers and Process Heaters

Boilers and process heaters are used at wide variety of facilities. 
  • Boilers burn natural gas, coal, wood, oil, or other fuel to produce steam.
  • Process heaters heat raw or intermediate materials during an industrial process.

Different federal regulations apply to these units depending in part on the size of the boiler, the type of fuel used and the type of pollutant being controlled.
