Along with the strong appeal for clean environment and sustainable development, wood chip dryer is the finished product of such appeals. Being the NO.1 brand of China mining machinery, Fote has the responsibility to answer such appeals. The following content mainly introduces about one heating device, called hot air furnace. Hot air furnace, using the coal as fuel, often heats air in wood chip dryer by the way of indirect heat transfer. During the process of indirect heat transfer, there are generally two situations.

One is that wind pipes are installed in furnace. The coal air is in pipe layer while the flue gas is in shell. Heat energy, being offered by coal material, radiates the exterior wall of wind pipe. The heat energy, being transmitted from exterior wall, heats the cold air in inner pipe. The inlet mouth of furnace is for cold air while the outlet is for high-temperature clean air. The other is that heat-transfer oil flows freely from one exchanger to another. Then, heat transfer occurs in wood shavings dryer between cold air and hot oil. The indirect heat transfer enjoys the features of high cleanliness of hot air and no humidity changes of air. The structure of hot air furnace is relatively simple.

According to the difference of technical demands and heat exchange amount, you can take different heating ways. Since the radiation way of flame to pipe is in direct, the texture for making pipe should meet some basic demands.
