Furnaces
A furnace is a heating device used in home and industrial applications. Home furnaces are comprised of burners, a heat exchanger, a draft inducer, and venting, as well as a blower, controls, and safety devices. It works as heat, originating at the burners, is drawn into the heat exchanger by negative pressure. The resulting combustion produces hot gases that move through the chambers of the heat exchanger, heat the metal walls of the heat exchanger, and leave the furnace at about 120 degrees.
Industrial heaters work when fuel flows into the burner and is burnt with air provided from an air blower. The flames subsequently heat a set of tubes, which pass the heat onto the radiant section or firebox where combustion takes place. Heat then radiates to another set of tubes that contains fluid, which is heated to the desired temperature.
