ECT is a small steam turbine co-generation system, which converts wasteful thermal energy from steam to electrical power. It is a two-stage velocity compounded impulse (Curtis type), partial/full entry, back pressure steam turbine intended for energy conservation in process industries using steam. It has an integral speed reduction gearbox suitable for coupling to generators or certain mechanical loads (blowers, pumps etc.,) upto a power level of 315 kW. The schematic shows a typical ECT installation (see brochure).

The Energy Conservation Turbine (ECT) can be used by any industry that currently uses a pressure reduction station (PRS) in their steam supply system. The ECT is installed in parallel with the PRS, to extract energy from the steam as it expands rather than simply throttle it as done by the PRS.

Brief write-up on the technology

Most industries that use steam raise steam at higher pressure than required by their plant equipment. The reason for this is that the minimum pressure generally offered by boiler manufacturers is 10.5 Kg/cm2, and by raising steam at higher pressure the size (and cost) of the steam lines between the boiler and process area comes down drastically. At the process area, the steam pressure is throttled down and controlled accurately by a Pressure Reduction Station (PRS) which senses and controls the down-stream process pressure. This steam then condenses in the process, transferring to the process the latent heat of vaporization. In the conventional PRV/PRS, lot of energy is wasted and by installing an ECT, this otherwise ‘wasteful’ energy is converted into electrical

ECT

Is designed to be a cost effective, rugged and reliable machine. It features an integrally machined turbine disc manufactured from a hardened stainless steel forging and a high-efficiency contoured nozzle for optimum aerodynamic performance. The high-quality bearings and precision ground helical gears ensure years of quiet, trouble-free operation. The ECT has a minimum number of components for high reliability. The ECT is offered to the market at a price, which will be paid back in about 9 – 18 months time (depending on the cost of steam generation). The turbine is coupled to an induction generator of 3000 rpm which will be load sharing with the grid/utility power. The extent of load shared is proportional to the steam flow and ECT is designed for a maximum power of 315 kW.
