Abstract
A boiler type of steam engine is described which uses a conventional boiler with an external combustion chamber which heats water in a pressure chamber to produce steam. A mixing chamber is used to mix the steam from the boiler with recovered recompressed steam. Steam from the mixing chamber actuates a piston in a cylinder, thereafter the steam going to a reservoir in a heat exchanger where recovered steam is held and heated by exhaust gases from the combustion chamber. Recovered steam is then recompressed while being held saturated by a spray of water. Recovered steam from a steam accumulator is then used again in the mixing chamber. Thus, the steam is prevented from condensing and is recovered to be used again. The heat of the recovered steam is saved by this process.
