Effect of Preheated Top Gas and Air on Blast Furnace Top …
WebForced air furnaces are available using four different fuels sources – natural gas, fuel oil, propane, and electricity. In general, they all work on the same principle: Heat from a fuel source is extracted in a heat exchanger or heating element inside the furnace. WebAs the flue gas becomes a less effective emitter of radiant energy, the firebox thermal efficiency drops. The second problem is that every excess pound of air ‘steals’ heat from the combustion process. Each excess pound of air entering the heater is an extra pound that must be heated to the furnace temperature. proyek blast furnace

All of the outside air and combustion products go out of the chimney to somewhere definitely outside. Very hot air from the burning of gas heats a metal piece called the heat exchanger. proyee
