What is Sealed combustion?
A grenade is an excellent example of a sealed combustion process. However, its is quite useless for everyday needs in that we want to benefit from the process, and therewith we must be able to control the speed of the combustion process. Sealed refers to the isolation of the combustion process from the living space. A campfire with a radiator filled with water over it, and piping and a pump to bring the hot water indoors to another radiator to provide heat, is a sealed combustion system as far as the living space is concerned. Bringing the fire indoors, the air supply for the fire must come from an intentional outdoor source, say through a pipe. The hot air to be circulated indoors is then isolated from the combustion chamber and the combustion system is “sealed” from an indoor perspective.
