Purpose of the development: Turbetexpanders-power generators based on jet-reactive (TDA-CPT) and vortex (TDA-VT) turbines are designed to generate electrical energy from the energies of compressed gas or steam.

Recommended application field: Energy (energy saving, alternative energy sources).

Technical characteristic: - power, kW - 100; - input pressure max, atm - 64; - pressure in a hibernation., Atn - 55; - input pressure min, atm - 6; - gas consumption with heating, kg / s - 1,1 ... 1,4; - weight of turbo unit, kg - 1670; - overall dimensions, mm - 1500; 700; 880.

Advantages over analogues: The main element of the TDA-CPT, which determines its prospects and main advantages, is the bladeless jet-jet turbine (SRT). Advantages of CPT allow creating TDA with payback period of 1-2 years, cheaper, simple, constructively and technologically, reliable and convenient in operation in comparison with TDA based on classical blade turbines. Turbogenerator power up to 500 kW can also be created on the basis of a vortex turbine, as well as a jet-jet turbine, is characterized by constructive and technological simplicity, cheap in manufacturing, but has a nominal operating mode at lower rpm. The last advantage of a vortex turbine makes it possible to create turbo-generators in a gearless version.

The development stage readiness: Ready for application

Technical and economic effect: The payback of the installation is up to 2 years.

Description of the development:
()
TDA-CPT consists of: - turboexpander on the basis of a jet-jet turbine; - single-stage reducer; - three-phase alternator, which uses an asynchronous motor; - automatic control, monitoring and protection systems; - power connection and energy control system, which is produced. The principle of the jet-jet turbine (CPT) is based on the transformation of the potential energy of the compressed gas into the kinetic energy of the jet flowing out of the traction nozzle and is at some distance from the axis of rotation. As a result, the reactive traction force on the traction nozzle and, correspondingly, the torque on the turbine shaft are formed, and when the shaft rotates, mechanical work is performed. Energy from the turbine shaft through the gearbox is transferred to the generator shaft and then converted into electrical energy.
