Thermal perspective description of regenerative hot air stoves
Thread Content
I would like to ask for a thermodynamic description of the heat exchange processes in the combustion chamber and the regenerative chamber of a regenerative hot air furnace~
A regenerative hot air furnace is, in fact, a regenerative heat exchanger
Fuel combustion generates hot flue gas that heats the heat storage material, which stores heat and thus its temperature rises. After passing through the high-temperature heat storage element, the cold air absorbs heat and its temperature rises, before being sent to the blast furnace.
I have seen regenerative flame arresters. It utilizes the large number of plates in the device to store heat, thereby absorbing the heat from the flue gas. Then, normal-temperature smoke is used to displace the heat from the panels, which saves energy and extinguishes the fire.
