Abstract:
A steam engine comprising a chamber having a first inlet valve (200, 312) and a second outlet valve (200, 314); a reciprocating piston moveable within the chamber; wherein at least one of the first inlet and second outlet valve is coupled to a computer controlled mechanism (704) operable to open and close the valve. A double beat valve for use with the stem engine of the invention and a method of optimising steam supply to the engine chamber are also provided.
Abstract:
The present invention provides a compressor powered by a pressurized gas, whether steam or another working fluid, and a system for extracting work using such as compressor. The pressurized gas may comprise a heated working fluid in a gaseous state, to displace a piston in an input circuit, which in turn displaces a piston in an output circuit, thereby compressing a compressible fluid or displacing an incompressible fluid. A purpose of the compressor is to convert waste heat, heat generated by the combustion of biomass or other fuels, or heat resulting from the concentration of solar energy into useful power, whether configured to produce compressed air or pump water, which can displace the electricity otherwise used for this purpose, or to produce electricity or motive force directly, through a hydraulic circuit. The system for extracting work does so by an output fluid which is compressed or pumped by a pressurized gas powered compressor.

Abstract:
The invention relates to a cylinder piston unit, especially for steam engines with expansion by heat influx, which is constructed as follows: a piston guided in the cylinder element has a displacer, a heating device is mounted on the cylinder element for the stroke area of a non-compacting displacer, the working medium is supplied in a vapour or liquid state in the area of the upper dead point, the expanded working medium is discharged at least in the area of the lower dead point. A pore burner is assigned to the cylinder piston unit in an advantageous manner. To this end, the invention provides for heat transfer sections (B, C) of a pore burner (50) which surrounds the cylinder head (43) along part of its height to be arranged at the level of the warm section (41) of the cylinder in the stroke area of the displacer (3) and at the level of the cylinder head (43).
Abstract:
An improved procedure for cold start-up of closed loop boiler set and Cheng cycle system wherein the venting step, the boiler swelling problem and blowdown step of the conventional start-up are eliminated by use of an external pressure source (40) to increase the operating pressure in the evaporator section (12) which minimizes premature phase change and accompanying volume increase.
