US4301655A - Combination internal combustion and steam …

The generated steam in the engine supplements its power, and assists in controlling engine temperature. An improved cylinder head for a fuel injected internal combustion piston engine is channeled so as to form a miniature steam boiler at the combustion end of the cylinder bore enabling injected water to flash into superheated steam in a few milliseconds.

High Temperature Steam Uses - MHI-INC

For example with a boiler one needs a high 10 Bar and even then the saturation temperature is only 180 C -even at 100 Bars the saturation temperature is only 311 C. Steam generators operate routinely at 300°C, i.e. well above the inversion temperature.

The potential of SO2 for reducing corrosion in WtE plants | …

2014/6/25 · Due to the high-temperature boiler corrosion induced by chloride-rich fly ash deposits, steam generation in today's Waste-to-Energy (WtE) plants is typically designed only for 40 bar/400 °C as an economic compromise between acceptable corrosion rate and maximum power generation. The high-corrosive metal chlorides in the fly ash can react with SO2 forming low-corrosive sulfates. The

History of the Steam Engine: From Its First Invention to the …

As the steam vessel moves round, it is supplied with steam from the boiler, and that which has performed its office may either be discharged by means of condensers, or into the open air. Sixthly, I intend, in some cases, to apply a degree of cold not capable of reducing the steam to water, but of contracting it considerably, so that the engines shall be worked by the alternate expansion and
