The Working Priciple of Wood Stove Fan

Wood stove fan is an energy-saving and environment-friendly fan without power supply. Its working principle is that the temperature at the bottom of the fan always drives the fan to run, and the hot air generated by the fan operation is blown to all corners of the room, so as to save the cost of fuel or wood, and make the whole room more warm and comfortable.


The wood stove fan is driven by heat


The wood burner fans for sale have no special power supply (no power cord or plug), so it is self-sufficient and relies on the power generated by the motor to rotate the fan blades. Therefore, the wood stove fan uses equipment to generate electricity by itself. The equipment can generate voltage through the temperature difference between two objects. When the wood furnace fan is placed on the furnace and a fire is made in the furnace, the furnace body absorbs heat and transfers the heat to the lower half of the furnace fan by conduction when the fan is placed on the furnace surface. This is why furnace fan manufacturers often require that fans be placed on smooth and horizontal surfaces to promote maximum heat distribution from furnace to fan. 


The heat propagates upward along the fan to the location where the equipment is located, which is about half of that of a typical furnace fan. When the equipment transfers heat from the bottom (hotter) part of the fan to the top (colder) part, the current is generated due to the temperature difference. Therefore, you will see the wires protruding from the equipment to the diesel stove fan. Therefore, the heat conducted from the firewood stove through the bottom of the furnace fan will generate current because it is transmitted to the top of the fan through the equipment, and the generated power provides power for the motor driving the fan blades.


The wood stove fan can only work in a certain temperature range


Wood stove fans usually only work within a certain temperature range, and the hotter the stove runs, the fan can usually distribute more air. For example, stove fans are designed to operate in a temperature range of 80-250 centigrade. The fan will not turn on until the furnace reaches a certain temperature. If the furnace runs too hot, the fan may be damaged. Our fan has a built-in safety device (just a piece of metal) at the bottom, so when the temperature reaches too hot, the fan will lift slightly from the furnace and cool down. In order to help prevent the furnace from overheating due to excessive combustion, it is always beneficial to use the wood-burning stove thermometer to pay close attention to the temperature level.
