Technical Report of Generating Power from Low Thermal Energy from Screw Expander Power Generator

Since the technology of conventional boiler is developed in the year 1867, efficient/complete usage of steam produced in boilers is a great task & usage of steam containing low temperature & pressure is a major problem. Though the quantity of steam is low at the moment, in a long run Billions of dollars are wasted & being wasted since past 150years, more over fossil fuels are not properly addressed for effective utilization of energy. Renewable energy utilization, saving heat/thermal energy wasting available fossil fuels & other combustible fuels is a major problem. Even though waste heat recovery is implemented, steam containing low grade temperature, pressure is not being utilized properly. The drive to save energy and reduce emissions and industrial need to cut costs and improve energy efficiency, screw expander are invented to effectively deal with the technological issue of utilizing low grade waste energy recovery which has not been satisfactorily addressed by traditional methods. These are robust & can process wet steam, converting mechanical energy into clean electrical energy.
