Expansion turbine – an electric power generation unit as a part of jet-reactive and vortex turbines

Function and area of implementation

Expansion turbine ‑ an electric power generation unit as a part of jet-reactive (ET-JRT) and vortex (ET-VT) turbines is used to produce electric power out of compressed gas or steam due to numerous power leaks in places where regulators and pressure reducers are mounted.

General technical characteristics, essence of invention

A paddle-free jet-reactive turbine (JRT) is a main ET-JRT element which makes it perspective and determines the main advantages. JRT transforms the potential energy of compressed gas into kinetic jet energy which flows from a tractive nozzle and is at some distance from the rotation axis. ET-JRT unit consists of expansion turbine as a part of a jet-reactive turbine; one-stage reducer; three- phase generator of alternating current performed by an asynchronous electric engine; systems of automatic control, checking and protection; system of power connection and control of the produced energy.

Comparison with world analogues, main advantages of invention

Existing world analogues are characterized by relatively high capital costs that do not provide the minimum acceptable payback period. The advantages of JRT enable to develop the ET with the payback period of 1-2 years. It is cheaper, of simple technology and design, safe and easy to use as compared to the ET on the basis of the conventional paddle turbines.
