Indirect Fired Air Heater
The indirect fired air Heater is made by Process Combustion Corporation located in Pittsburgh, Pennsylvania for the past 40 years. Their projects are mainly designed for, but not limited to, the chemical and petrochemical industries. They maintain strict quality control, follow environmental regulations. Their products have been used for combustion, heat transfer, pollution systems and incineration. Their knowledge in a variety of industries is beneficial to their customers. Their knowledge and experience of incinerating hazardous waste is extremely beneficial to a variety of industries. Their knowledge of heat exchangers, heat recovery boilers, wet scrubbers, bag houses and electrostatic precipitators, combined with VOC destruction and acid gas systems, is extremely helpful when designing, building and servicing these systems.
The original design for the 6 MM BTU/HR burner was for turning radioactive waste to glass for ease of disposal.
The original design process was to take Rad dirt (radiological waste),in drums, and feed the dirt into the system. The drums would be cut, and the iron magnetically removed. There is a 50’ X 9’ rotating trommel into which 555 degree Fahrenheit air is injected from the heat exchanger to create glass.
Components of the 6 MM BTU/HR Burner
The Indirect Fired Air heater when fully assembled is approximately 36 feet long, 7-1/2 feet wide and 5 feet tall. The exhaust stack is 30 feet in length and 30 inches in diameter.
The perforator has a temperature rating of 1000 degrees Fahrenheit with a set point at 1050 degrees Fahrenheit. The temperature rating at the exhaust end is rated at 413 degrees Fahrenheit.
The burner is fired by propane gas, with a 3inch valve on the input line. All piping, fittings and rack use a Sherwin-Williams industrial primer or equivalent, and finished with Sherwin-Williams special blue enamel unless otherwise noted. Valves and switches have standard manufacturer’s finish.
The controls are mounted inside a NEMA 4 Hoffman enclosure. The operation of the burner is PLC controlled. Some of the indicators for ease of operation and maintenance include, “interlocks completed”, “purging”, “ready to start”, “flame on”, and “reset required”. There are low and high pressure switches for controlling the propane flow. The exhaust stack is insulated with 1 inch Mineral Wool insulation with embossed aluminum jacket, and is designed for waterproof construction.
The Heat Exchanger Inlet and Outlet are both 18 inches in diameter. The inlet is rated at 170 degrees Fahrenheit and designed for 3/8 inch lateral expansion, and 1/8 inch vertical expansion. The Outlet is rated at 555 degrees Fahrenheit , and designed for 1 inch lateral expansion and 5/16 inch vertical expansion. It is insulated with 3 inches of Mineral Wool with an embossed aluminum jacket, and designed to be waterproof. The combustion air fan has a 20 H.P. Baldour motor, and is rated at 9000 CFM @ 8 inch W.C. It requires an 18 inch high, 4’4” x 3’2” pedestal for support. The two expansion joints are made from A36 Carbon steel, shop coat of Aluminum-Oxide and weigh approximately 250 pounds each. They have a 6’x16” inside flange opening and an approximately 3” wall.
The Fan Exchanger skid, fan silencer stand, burner skid and two lifting beams are made from A36 Carbon steel. All bolts, nuts, and washers are carbon steel high strength A325, grade five, unless otherwise noted. The external surfaces have one shop coat of High-Temperature Aluminum-Oxide.
The combined weight is approximately 2350 pounds.
The installation location should be able to sustain Dead Loads ranging from 1250 pounds to 6500 pounds, along with an additional 1000 pound snow load. The anchor bolts will maintain an overturning moment ranging from 40,000 Ft.-lbs. - 140,000 Ft.-lbs.
This unit was originally designed in 1996. It was purchased by a customer but never assembled or put into service.
