Industrial drying oven, drying furnace with indirect heat exchanger
1. Introduction
for
Gas Fired Hot Air Furnace
The direct fired furnace is a style of heater in which a burner provides hot gasses that transfers their heat energy for drying final products. It's customized designed and manufactured according to customer's detailed requirements.
Oil, natural gas and other fuel can combust to produce high temperature clean flue gas through oil or gas burner, and the flue gas can provide the hot air to the drying system directly as heat source or heating the air with the heat exchanger as heat source.
2. Working principlesWhen the fuel
is burned in firebox,high temperature smoke gas
is produced. Those smoke gas
is sent byhot air furnace which has strong exchange heating function to dried air. After quantity of heat is emanated,hot
fueling gas temperature
is decreased
to 250°C and
those gas are
exhausted by
fan. Fresh air is sent
to hot air
furnace by selected blow
fan machine. After absorbed heating energy, when air temperature reaches to specific degree, it is sent to outlet of hot air,while hot air temperature meet the highest limited point,the
burner will
stop
burning automatically or turn to small fire burning, when hot air temperature decreases to
the lowest preseted degree, burner start running again, the speed of heating can be adjusted by air inlet valve.3. Technical Parameters
