this is called a heat exchanger
with an open campfire it may not be a physical object
with an electric heater it may be miles away at a power plant

What is the difference between a condensing central heating boiler and a combination boiler?
A combination boiler can use one of two different fuels to heat the water. Common combinations include natural gas/propane and oil, or wood and oil combinations. A condensing boiler uses a secondary heat exchanger to condense water vapour (steam) in the products of combustion down to water. Here's what that means: When any hydrocarbon (gas, propane, oil, even wood) burns, it gives off at least two "products of combustion. The carbon combines with oxygen to create CO2, carbon dioxide. The hydrogen combines with oxygen to create water vapour, or steam. (If combustion is "incomplete," there will be other trace products as well.) It's the water vapour or steam we're concerned with here. To boil 1 pound of water requires 960 BTUs of heat. Conversely, if you condense steam down into 1 pound of water, you will recover 960 BTUs. The fuel is burned in the "primary heat exchanger," where of course it releases a tremendous amount of heat into the water we're warming up. Then the "products of combustion" are drawn by a fan into the "secondary heat exchanger." When the water vapour or steam component of the products of combustion hits the relatively cool walls of this second heat exchanger, they condense down into liquid water. As they do, they release heat into the boiler water through the walls of the secondary exchanger. The liquid water then goes down a drain. Obviously, the boiler water has to be cooler than the steam component of the products of combustion in order for the heat to travel into it. So we make sure that this water is what's coming back to the boiler from the heating system. Again, for this method to work well, it's best applied in a "radiant in-floor" type heating system, where we don't heat the boiler water up to as high a temperature in the first place. --The HVAC Veteran
Is the furnace an internal or external combustion engine?
An ordinary furnace is not an engine at all, because it does not directly cause mechanical motion. The heat or expanding gases released in a furnace can be used to drive an engine, but that is a separate component from the furnace. If a furnace is used in this manner, the engine is an external combustion engine.
What are the two types of heat engines?
internal and external combustion engine
What are examples of heat engines?
internal and external combustion engine
What is the use of air preheater in boilers?
preheater is used to heat the air at Inlet of the furnace of Boiler By using Heat contents of Exhaust gases. This will minimize the fuel Consumption.

What are the two products of combustion of a candle?
Products include heat, carbon, and water.
What are the three products of combustion?
heat, smoke, toxic gases
What is an aluminum extruded heat sink?
A heat sink is a device or fixture that transfers heat from a component, such as the CPU or processor, it acts like a radiator in which it transfers the heat into the air. Aluminum is shaped by the extrusion process which is like squeezing tooth paste out of a tube.
What are two ways heat can be involved in chemical change?
heat can be one of the products as in a combustion reaction and it can be used as a catalyst
What products are produced in a complete combustion of natural gas?
3CO2+8N2+4H2O+heat
What are all the products of a hydrocarbon combustion reaction?
Carbon dioxide, Water Vapor, and Heat
What are the two products made during the complete combustion?
Mainly CO2 and H2O - Carbon Dioxide and Water. (Also heat, depending on if you are including it or not.) This can also be shown as an equation: Fuel + Oxygen → Carbon Dioxide + Water (and heat)
How does heat combustion of paraffin compare to heat combustion of propane?
how does the heat of combustion of propane compare to the heat of combustion of paraffin wax
What is the combustion triangle?
The triangle seen in combustion reactions on top of the arrow separating the reactants from the products is the Greek letter delta which means heat is added.
How is combustion made?
To combustion is to undergo combustion. Combustion is a process in which a substance reacts with oxygen to give heat and light.What are always the two products of a combustion reaction?A combustion reaction is when all substances in a compound are combined with oxygen, which then produces carbon dioxide and water.
