Hot blast furnace: note the flow of air from the stove in the background to the two blast furnaces, and hot air from the foreground furnace being drawn off to heat the stove. Hot blast refers to the preheating of air blown into a blast furnace or other metallurgical process. As this considerably reduced the fuel consumed, hot blast was one of ...
A furnace needs no less than two stoves, but may have three. One of the stoves is 'on gas', receiving hot gases from the furnace top and heating the checkerwork inside, whilst the other is 'on blast', receiving cold air from the blowers, heating it and passing it to the blast furnace.
Diagram of a radioisotope heater unit. A radioisotope heater unit (RHU) is a small device that provides heat through radioactive decay. [1] They are similar to tiny radioisotope thermoelectric generators (RTG) and normally provide about one watt of heat each, derived from the decay of a few grams of plutonium-238—although other radioactive isotopes could be used.
A nuclear thermal rocket (NTR) is a type of thermal rocket where the heat from a nuclear reaction replaces the chemical energy of the propellants in a chemical rocket. In an NTR, a working fluid, usually liquid hydrogen, is heated to a high temperature in a nuclear reactor and then expands through a rocket nozzle to create thrust.

For example, a blast furnace may have several "stoves" or "checkers" full of refractory fire brick. The hot gas from the furnace is ducted through the brickwork for some interval, say one hour, until the brick reaches a high temperature. Valves then operate and switch the cold intake air through the brick, recovering the heat for use in the ...
A thermic fluid heater (TFH), [1] also known as a thermal oil heater, is a device used for indirect heat transfer through a thermic fluid. It heats the fluid to a desired temperature and then transfers that heat to various processes without any direct contact between the heating source and the product.
