Heat Exchangers/Air Heaters
The Corporation offers a full line of flue-gas-to-air
heat exchangers to complement the WEBB series solid fuel burner.
These heat exchangers wipe the energy from any hot (12001800°F)
flue gas and preheat fresh ambient air to the desired temperature
rise. Ideal for industrial space heating, air make-up units,
indirect drying requirements and lumber kilns.
The system features Allen-Bradley/Rockwell Automation based
controls. This degree of control allows for touch-screen display,
control and manual or automatic equipment start/stop. The controls
can download all parameters at pre-set time intervals to a networked
PC for data recordkeeping of any tracked parameter. A modem connected
to the controls allows for remote monitoring and adjustment of
the system. Controls will volumetrically track inbound fuel consumption,
and outbound energy flow in Btu/hr. The controls command any
selected burner temperature. Controls also monitor all exchanger
temperatures and safety switches, fuel flow in pounds, exchanger
inlet and outlet temperatures and burner temperature and cause
system safety shut down in case of extremes.
Flue gas energy recovery is accomplished using a VW flue-gasto-air
exchanger. Flue gases are slightly diluted to 1,200°F ahead
of the exchanger. This exchanger wipes energy from the flue gases
and immediately dumps that energy directly to Your Company's
industrial facility to meet its hot air requirements or, if desired,
Attached drawings illustrate the flue-gas-to-air exchanger concept.
These drawings are of an actual 2 MM Btu/hr exchanger which has
been operating for over 7 years in Ohio. Performance has been
outstanding. The exchanger uses standard spiral duct as heat
transfer surface. It is self-contained in its own weatherproof
