Direct-fired gas (oil) hot blast stove uses direct fuel combustion, hot air is formed after high-purification treatment, mixing, etc., and it comes into direct contact with materials, and is heated to dry or bake. This method reduces fuel consumption by about half compared to using steam or other indirect heaters. Therefore, without affecting the quality of the dried product, direct high purification hot air can be used.
The high temperature flue gas (1100 ~ 1350 ℃) produced by burning natural gas, liquefied petroleum gas (LPG), city gas, biogas, light diesel or heavy diesel is mixed with cold air and mixed into a certain temperature directly into the drying room or The baking room is in contact with the materials to achieve the purpose of heating and evaporating moisture. The gas (oil) hot air stove is a device that provides hot air for the next process.

引进国外先进技术，采用了强化传热方式和耐热钢材料，结构紧凑，体积小，寿命长； ● The introduction of foreign advanced technology, the use of enhanced heat transfer methods and heat-resistant steel materials, compact structure, small size, long life;
间接加热空气的方式，使烟气和空气各走其道，加热无污染，满足了对热风有清洁、防火和防爆要求的应用领域的需要； ● Indirect heating of the air, so that the flue gas and air go their separate ways, heating without pollution, meeting the needs of application fields that require hot air to clean, fire and explosion;
采用插入式热风循环风机，与热风炉换热体一体化安装，节省了场地，降低了噪音，减少了散热，并便于维护； ● Using a plug-in hot air circulation fan, integrated installation with the heat exchanger of the hot blast stove, saves space, reduces noise, reduces heat dissipation, and facilitates maintenance;
配有进口燃烧器，自动化程度高，可靠性强，控温精确。 ● Equipped with imported burners, high degree of automation, strong reliability and accurate temperature control. 油加热炉由于二次换热造成的热效率低的不足，节油节电，经济效益显著； The furnace directly outputs high-temperature air through a single heat exchange, and has high thermal efficiency, which makes up for the lack of low thermal efficiency caused by the secondary heat exchange of steam boilers and heat-conducting oil heating furnaces, saving fuel and electricity, and significant economic benefits;
运行费用低，与电加热烘干方式相比，仅为电加热运行费用的1/3； ● Low operating cost, compared with electric heating and drying methods, it is only 1/3 of the operating cost of electric heating;
热风温度高，间接式热风炉热风输出温度可达350℃，这无论是导热油加热炉和蒸汽锅炉都难以达到的； ● The hot air temperature is high, and the hot air output temperature of the indirect hot air stove can reach 350 ° C, which is difficult to reach regardless of the heat transfer oil heating furnace and steam boiler;
初投资低，可安装或架设于用热设备顶部、底部或一侧，不需加建炉房，在相同的供热量下，其初投资仅为导热油炉和蒸汽锅炉的一 ● The initial investment is low, and it can be installed or erected on the top, bottom or one side of the heating equipment. No additional furnace room is required. Under the same heat supply, the initial investment is only one part of the thermal oil furnace and steam boiler.
