zhenghe/正和热风烘干炉 热风烘干机 按照输出介质洁净度不同可以分为直燃式热风(烟气)炉和间接式热风炉。 根据燃烧方式不同可以分为固定炉排热风炉、机烧热风炉，沸腾燃烧燃煤热风炉。 以燃料种类不同可以分为煤、生物质、石油液化气等，燃料种类的不同意味着燃烧装置的改变。 以输出风温不同，可以分为高温热风炉、中温热风炉、低温热风炉。 以热风炉换热器的摆布形式可以分为合置式和分置式，一般情况下，根据用户厂房情况合理选择，并不 能完全就说哪一种就好。 判断热风炉节能效果好坏z根本的一条就是达到热风温度换热后烟气温度的高低。烟气温度越低，热利用 率就越高，反之则热效率较低。
According to the cleanliness of the output medium, it can be divided into direct-fired hot air (flue gas) furnaces and hot air furnaces.
According to the combustion method, it can be divided into fixed grate hot air furnaces, mechanical firing hot air furnaces, and fluidized bed combustion coalfired hot air furnaces.
According to the type of fuel, it can be divided into coal, biomass, liquefied petroleum gas, etc., and the difference in fuel means a change in the combustion device.
According to the output air temperature, it can be divided into high-temperature hot air furnaces, medium-temperature hot air, and low-temperature hot air furnaces.
According to the arrangement of the hot air furnace heat exchanger, it can be divided into integrated and separate types., it should be reasonably selected according to the user's factory conditions, and it cannot be said that one type is always better than the other.
The fundamental for judging the energy-saving effect of a hot air furnace is the temperature of the flue gas after heat exchange at the target hot air temperature. The lower the flue gas, the higher the heat utilization rate; conversely, the thermal efficiency is lower.
