Oil/Gas-Fired Hot Air Furnace:
A hot air furnace is a thermal energy conversion device that utilizes fuel (blast furnace gas, coke oven gas, converter gas, mixed gas, producer gas, calcium carbide furnace gas, natural gas, liquefied petroleum gas, diesel oil, heavy oil, pulverized coal, and waste, etc.) to release chemical energy through combustion in the furnace, heating low-temperature air to high-temperature air at a certain temperature. Hot air furnaces can also use other thermal energy (such as electrical energy and waste heat) to heat air.
Performance Features:
1. Wide applicability to fuel types; hot air furnaces can be manufactured for burning blast furnace gas, coke oven gas, converter gas, mixed gas, producer gas, natural gas, liquefied petroleum gas, chemical waste gas, heavy oil, diesel oil, pulverized coal, and other fuels.
2. Output hot air temperature control with temperature deviation within ±5℃.
3. Targeting the setpoint temperature, the fuel and air supply are automatically adjusted for ease of use.
4. Non-standardized design, highly targeted, better able to meet user requirements.
5. Wide output hot air temperature control range, suitable for drying needs in various industries.
6. Capable of continuously providing constant-temperature, constant-pressure, purified hot air.
7. Fully automatic operation, using imported electrical components, with high operational reliability and accuracy, capable of networked control with industrial configuration systems.
