The answer to how does a oil furnace work is rather easy. There is an oil burner here where the fuel from the storage tank of the furnace is pumped. The fuel here is pressurized and combined with sufficient air and this mixture of fuel and air is sprayed through a small nozzle into the fire box. This is ignited by the electric spark that is generated by the burner’s transformer and this flame heats the air in the heat exchanger to get expelled into the surrounding air. This is the answer to how does an oil furnace work.
If you want to know how does a gas furnace work, its heat is supplied by burning of natural gas. Here a mixture of gas and air flows into the burner to get ignited by the pilot. When this combustion occurs, the burner produces warm air to fill the heat exchanger chamber. Once this becomes hot, the air that passes around it absorbs warmth and passes into the air ducts to heat your home or office. This is how a gas furnace works.
If you see a blast furnace, you tend to wonder how the blast furnace works. Here the fuel and ore are supplied on the top of the furnace while air is blown into the bottom of the chamber to facilitate chemical reactions in the furnace. And if you want to know how a propane furnace works, it generally draws air inside to be warmed with flames of propane. This warmed air is then sent through the house through metal ducts.
Although you know how a furnace works, it is also important that you know how pressure switch works in furnace.
