High pressure steam enters, red, and exhausts, yellow. The uniflow type of steam engine uses steam that flows in one direction only in each half of the cylinder. Thermal efficiency is increased by having a temperature gradient along the cylinder. Steam always enters at the hot ends of the cylinder and exhausts through ports at the cooler centre.
The contract between Cyclone Power Technologies and Phoenix Power Group for the lower output WHE steam engine [21] states that Phoenix Power Group will make a $150,000 progress payment "Upon the completion of 200 hours of durability testing of WHE version 5.0 as conducted and/or overseen by OSU. The durability testing shall consist of the WHE ...
A company in India [22] manufactures steam-powered generators in a range of sizes from 4 hp to 50 hp. They also offer a number of different mills that can be powered by their engines. In matter of technology, notice that the Quasiturbine is a uniflow rotary steam engine where steam intakes in hot areas, while exhausting in cold areas.
Uniflow steam engine, a steam engine with a long uniflow cylinder that receives inlet steam at each end (for a double-acting engine) and exhausts through ports at the centre. Uniflow diesel engine, a two-stroke diesel engine with inlet through piston-ported fixed ports in the lower part of the cylinder, and exhaust through valves in the ...
The Cyclone Waste Heat Engine (WHE) is a single-acting, Uniflow steam engine.The two main variations are the WHE-25, a six-cylinder radial engine that was under development until November 2013, and the 3-cylinder WHE-DR that has been under development since. [2]
Supercritical steam generators are frequently used for the production of electric power. They operate at supercritical pressure. In contrast to a "subcritical boiler", a supercritical steam generator operates at such a high pressure (over 3,200 psi or 22.06 MPa) that actual boiling ceases to occur, the boiler has no liquid water - steam separation.
Johann Stumpf of Technische Hochschule Charlottenburg (today Technische Universität Berlin) is best known for popularising the uniflow steam engine, in the years around 1909, and his name has always been associated with it. The basic uniflow principle had been invented many years before.
The uniflow engine used poppet valves and half cylinders which allowed steam to pass into the engine was then used to create a high pressure environment that was key to the function of the uniflow engine. It was used in ships, steam locomotives and steam wagons but was displaced by steam turbines and later marine diesel engines. [50] [52] [53] [17]
