Direct gas hot blast stove uses direct combustion of gas, and then produces hot air through purification. Hot air contacts directly with materials, and then heating and drying materials. The heating characteristic of gas hot blast stove is that it saves about half of the fuel compared with other drying methods. At the same time, it is highly purified hot air, which will not cause harmful pollution to materials. Indirect gas hot stove, hot air does not directly contact materials, mainly applicable to materials that are not allowed to be polluted, such as food, medicine and materials with high temperature sensitivity. The indirect gas hot blast stove heats air by heat exchange, and achieves the effect of heating and drying by increasing the indoor temperature. 燃气注意使用的范围。
