Gas/oil hot air stove use oil or combustible gas as fuel and are burned through a burner to produce high-temperature gas. In the drying process and the wet granulation process, the hot air stove is a necessary related equipment,which provides the necessary heat source for the drier system. The heat of the high-temperature gas is transferred to the heated air after heat exchange by the hot blast stove. The heated air is sent in through a blower to absorb heat. After the temperature rises to the rated value, it is sent out from the hot air outlet for drying and heating. The series of gas/oil hot air stove has the features of high temperature,low pressure,accurate temperature control and high utilization of heat engery.
   

The series of gas/oil hot air stove has the features of high temperature, low pressure, accurate temperature control and high utilization of heat energy. The air pre-heater is set up in the tail of large hot air stove to improve the efficiency of the hot blast stove. The convective heating surface adopts a higher reasonable flue gas flow rate on the basis of rigorous calculation to ensure the full heat transfer of the furnace body and the high thermal efficiency of the hot air stove.
