Indirect combustion system

This system belongs to a clean and energy-saving indirect heating device, which is a fully integrated system including a heat exchanger, combustion chamber, burner, combustion fan, and gas valve group. The heater body is made of high-temperature alloy. Mainly used in a series of processes such as circulating ovens and dryers where hot gases must be isolated from combustion exhaust gases. The burner, combustion chamber (heat exchanger), and exhaust gas pipeline in the indirect air heater configuration industry form an independent unit, which is easy to install and provides performance.

This device integrates heat transfer between the combustion furnace body and the radiation section, with the combustion furnace body directly serving as the body of radiation heat transfer, greatly increasing heat transfer intensity while reducing equipment volume and consumables.

The principle of this heating device is that the fuel is fully burned in the combustion chamber, and the hot flue gas after combustion is exchanged for fresh cold air through an efficient plate heat exchanger. The specific process is as follows: the fuel and the required combustion air are introduced into the furnace through an external combustion machine for full combustion. The burned flue gas undergoes high-intensity radiation heat transfer and forced convection heat transfer to the clean air in the air duct through the furnace. Then, the flue gas enters the high-efficiency plate heat exchanger, undergoes forced convection heat transfer with the clean air in the adjacent channel through the partition wall, and is discharged through the flue gas outlet; Clean air enters the equipment through the air inlet and undergoes reverse forced convection heat transfer with the fuel flue gas in adjacent channels in the high-efficiency plate heat exchanger. Subsequently, the air enters the air duct outside the furnace to receive high-intensity radiation heat and convective heat from the flue gas in the furnace, and enters the drying process system of the clean hot air required by the user through the air outlet.
