热风炉的作用就是为污泥烘干机提供干燥所需的热源，而干燥的温度对物料的意义非常大。温度低的话，干燥时间过长，成本上升，温度过高可能会影响***终的品质。比如说出现物料焦糊情况。污泥烘干机可以干燥多种不同类型的物料，因此具体的温度范围也不相同，需要具体情况具体对待。   从热风炉热源的燃烧产生热量，然后输送到污泥烘干机筒体内部，在进气口的温度一般在300到800度之间，因为物料着火点不同，所以具体数值要依物料类型来定。热气流随着物料不断向尾部移动，在排出的烟气温度一般在200度以下。                    
     烘干机尾气温度过低则达不到干燥的效果，若尾气温度过高则物料自身携带温度也会过高，出料时煤泥与外界空气接触瞬间就会发生凝结现象，煤泥表面产生水珠，反而违背了干燥煤泥的目的。因此烘干机的尾气温度应控制，保证成品不受影响。   系统的看待烘干问题。把烘干机作为一个系统来设计，按烘干机的******通过能力来配套，严格要求相关设备达到性能指标．确保烘干机产量******时，热供应状态依然******。因此在干燥热源的选取上、热风炉的配套建设上、燃烧时具体温度的调节和控制方面需做好。
The effect of hot blast stove is needed for sludge dryers provide dry heat source, and the temperature of the drying of the meaning of the material is very big. Low temperature, drying time is too long, the cost rise, high temperature could influence the final quality. Such as material anxious burnt condition. Sludge drying machine can dry many kinds of different types of material, so the specific temperature range is not the same, need particular case is particular treatment. From the heat source of hot air stove burning heat, and then transported to the sludge dryer cylinder inside, in the temperature of the air inlet, generally between 300 to 800 degrees, because the material of ignition is different, so the specific value depending on material type. Stream as the material, which is moving towards the tail flue gas temperature in discharge generally below 200 degrees. The dryer exhaust temperature is too low to reach the effect of drying, if the exhaust temperature is too high material carries the temperature will be too high, when discharging coal slime will happen in an instant by contact with the outside air
