Gasification furnace can directly convert any chemical raw materials, such as straw, wood chips and other combustibles into gas, with high calorific value and good combustion effect. By applying infrared combustion technology, a high furnace surface temperature (nearly 1000 degrees Celsius) can be obtained. Due to its ability to carry energy, infrared radiation does not require air as a propagation medium and has strong penetration capability. So the thermal efficiency is greatly improved, which shortens the heating time of the object, thus making the heating faster, shortening the labor time, and reducing fatigue.
