Arani Ships Out its First Vapor Turbine
Hyderabad-based Arani Power System has dispatched 'Kalina cycle vapor turbine' for its overseas client. The vapor turbine is used to generate power from waste heat recovery from cement plant and is the first of this kind being designed and manufactured in India by Arani. It is ranked thir d in the world in power generation capacity by Kalina cycle. The Kalina cycle is principally a 'modified'rankine cycle. The transformation starts with an important process change to the Rankine cycle - changing the working fluid in the cycle from steam to a mixture of ammonia and steam vapor. Compared to the conventional century-old Rankine cycle, a Kalina cycle power plant may offer efficiency gains of up to 50 per cent for low heat energy sources such as geothermal brine at 150¦C to 210¦C.
