A boiler is an equipment unit that uses a fuel source (e.g. natural gas, propane, or oil) to produce hot water or steam. Boilers are used for heating water, space heating, and steam generation. Process heaters and steam generators are included under boiler equipment units.
Boilers do not include dryers in which the material being dried is in direct contact with the products of combustion (e.g. cement or lime kilns, glass melting furnaces, or smelters). Please see Drying Ovens.
What Needs a Permit?
Boilers, process heaters and steam generators with a rated heat input capacity of 1 million British Thermal Unit (BTU) per hour or greater.
Boilers, process heaters and steam generators of any size, that are not fired exclusively on natural gas, liquid petroleum gas, or any combination thereof.
Boilers, process heaters and steam generators that are used in the same process or connected to the same header and have a combined rated heat input capacity of 1 million BTU per hour or greater.
Additional Permitting Information
- Each boiler, process heater or steam generator will be permitted individually if rated at 1 million BTU per hour or greater.
- Any boiler, process heater or steam generator rated at 1 million BTU per hour or greater must be source tested after install. Units rated less than 5 million BTU per hour may test using a portable NOx analyzer instead of undergoing a full source test.
