Flue Pipe - $375 to $850 Gas Valve - $225 to $1,050 Heat Exchanger Repair - $100 to $225 Heat Exchanger Replacement - $475 to $1,550 Igniter - $175 to $350 Oil Combustion Chamber - $175 to $625 Relay Switch - $165 to $330 ...
If the furnace is gas-tight as well as the doors, burner-lighting holes and flue offtakes then a furnace can be operated at high pressure. The furnace, however, must be lighted at atmospheric pressure and sealed (except for the flue) before increasing the flow to full value; the pressure...
The flue gas from the reformer heater (shown as a dotted line) is used to preheat the burner air and the gas to the reformer. In the HYL reformer, the top gas is cleaned and scrubbed, and then most of the CO2 is removed. This processed top gas is not sent to the reformer, but ...
A flue gas exhaust flue (the smaller diameter steel "pipe" that exits near the bottom left of the gravity furnace and connects to a brick chimney in our photo - and that larger diameter round duct at the top center of the gravity furnace. That large round warm air supply plenum or duct...
The barometric damper provided with the appliance must be properly installed on the flue pipe of the oil unit. The purpose of the damper is to limit the draft, if necessary, in the oil unit evacuation pipe. Since the evacuation pipe of the oil unit is connected to the evacuation pipe of...
They called an idiot who "solved" the problem by replacing the draft hood with straight flue pipe. My advice to fix the system led to bringing in someone who made it worse. I am disappointed to have to say I'm a bit overwhelmed by the complexity of this problem and I'm left ...

Furnaces don’t create carbon monoxide under normal conditions, in most cases it is produced because there is not enough combustion air or the flue pipe is not right (improper combustion). Back drafts among many other complex scenarios could give you a recipe for disaster. What is your life...
The oxides formed readily appear as entrained flue gas dust and may be recovered as such further downstream in the furnace exhaust gas system. During its travel through the top of the furnace, the extra reducing agent is thus brought in contact with air, and at the high temperatures in the...
A baffle (not shown) in flue 19 controls the pressure of the furnace atmosphere within outer cover 16. Again, the plenum chamber 22 and distribution pipe 26 can be replaced by conventional burners simply firing their product of combustion against inner cover 15. The heating arrangement disclosed...
