A boiler or steam generator is any external combustion equipment, fired with any fuel, used to produce hot water or steam. Process heaters include any unit fired with any fuel which transfers heat from combustion gases to water or process streams, including reformers.
Dryers in which the material being dried is in direct contact with the products of combustion, cement or lime kilns, glass melting furnaces, or smelters, are not considered process heaters. Please see Drying Ovens.
A permit is required for all boilers, process heaters and steam generators with a rated heat input capacity of 1 million BTU per hour or greater or boilers, process heaters and steam generators of any size that are not fired exclusively on purchased quality natural gas, liquid petroleum gas, or any combination thereof.
Each boiler, heater or process heater will be permitted individually if rated at 1 million BTU per hour or greater.
A permit is required if the aggregate rated heat input capacity of all boilers, process heaters and steam generators used in the same process is 1 million BTU per hour or greater.
Regardless of the aggregate heat input, individual boilers or water heaters rated at under 1 million BTU per hour are subject to Rule 414.
For modifications of permitted equipment resulting in an increase in boiler rating, the fee is assessed in accordance with fee schedule 2 (see Rule 301, Section 308.3)based on the incremental increase in BTU/hr resulting from such change.
For modifications resulting in no increase in rating, the fee shall be based on Rule 301, Section 306.2.
