Make simple and crude, often for civil engineering, it then follows " northeast heated kang " design principle, thermal source utilization rate is low, flue gas and hot blast easily mix, and cause
After drying, food dust content increases, and the heavy metal index such as sulfur, phosphorus is too high；Another part air stove makes normalization relatively, but
Be design excessively backward.Heated to by the cold air of pipeline by the way of directly heating air line.Although it is this
Mode avoids flue gas and the problem of air mixing, but because flame directly heats pipeline, the service life of pipeline can be year by year
The pipeline leakage reducing and producing, the service life of air stove lowers significantly.And due to the temperature in fuel combustion process
Deviation cause export hot-air temperature unstable, in temperature, lower deviation can reach 10-15 degree.The change of this temperature causes
The color and luster of material drying changes thus affecting the selling price of material.
In terms of environmental conservation, mainly with coal as fuel, this results in the pollution to environment for traditional air stove, thus
It is faced with the problem prohibitting the use of or limiting use.
