摘要： An Advanced Uniflow Rankine Engine (“AURE”) that is effective and thermodynamically efficient at higher speeds (e.g., 400-1800 rpm) and has low torque output. This allows the AURE to be compact of size without the need for a massive foundation found in prior art steam engines. The AURE includes an admission valve assembly, a cylinder head/valve gear assembly, a cylinder/piston assembly, a crank shaft assembly, an external sump, and an integral condenser. The admission valve assembly includes a counterbalancing poppet valve and valve stem that creates counterbalanced unsupported areas that allow the poppet valve to operate at higher speeds. The AURE can be fueled by raw, unprocessed fuel, including biomass, to generate efficient energy in a smaller overall package.

摘要： A rotary external combustion engine wherein energy is supplied to a working space of the engine by direct injection into the stator of liquid water at a high temperature and pressure. The water acts as a heat-transfer medium. Some of the liquid water spontaneously vaporizes on injection, during the rotor. Liquid water is exhausted from the working space and recycled to an external heat exchanger for reheating prior to reinjection. The engine is capable of a thermal efficiency greater than that of the Rankine cycle.

摘要： An apparatus, system and method for generating power, utilising a novel mono-block reciprocating piston engine with reduced or zero harmful emissions. The mono-block comprises a composite internal combustion IC section and Organic Rankine Cycle ORC section. The mono-block engine comprises two or more cylinders each having a piston housed therein; a composite internal combustion IC section controlling the displacement of at least one of the pistons and; an Organic Rankine Cycle ORC section controlling the displacement of at least one of the pistons; wherein the IC and ORC pistons connect to and drive a common crankshaft of the mono-block engine power plant; and wherein the Organic Rankine Cycle operates by the heat generated by the combustion in the internal combustion section, and the displacement of the pistons in the ORC section is achieved by injecting heated and pressurised ORC fluid.

摘要： A flexible coal-fired power generation system includes a thermal system for coal-fired power generating unit and a high-temperature heat storage system connected in parallel, wherein: the heat storage system includes a heat storage medium pump (17), a cold heat storage medium tank (18), a hot heat storage medium tank (20), multiple valves, and a heat storage medium and feedwater heat exchanger (21). A heat storage medium heater (16) locates in the boiler (1) and is connected with both the cold heat storage medium tank (18) and the hot heat storage medium tank (20). Through the heat storage medium pump (17), the flow of heat storage medium that enters the heat storage medium heater (16) is adjusted to reduce the output of the steam turbine when the boiler (1) is stably burning.
