EFFICIENT LOW TEMPERATURE THERMAL DIFFERENCE STIRLING IN MUMBAI

History: Patented in 1816 by Reverend Dr.Robert stirling, this heat-engine was designed to replace notoriously dangerous steam engines during the industrial revolution. Stirling’s invention never replaced steam engines on a large scale. but it did drive the invention of better grades of steel and safer steam engines. How it works: Where steam engines require very high temperatures and pressures to function, the stirling  Engine uses an external heat source to cause expansion and contraction of the gas inside the  chamber, which in turn drives the piston.Simply apply a heat source that is 20 degree more than the environmental temperature and  your  Stirling Engine will run. Try a hot cup of tea or a very warm hand on a very cold day! What’s  Stirling  Engine? A Stirling engine is a heat engine that operates by cyclic compression and expansion of air or other gas, the working fluid, at different temperature levels such that there is a net conversion of heat energy to mechanical work.The engine is like a steam engine in that all of the engine's heat flows in and out through the engine wall.This is traditionally known as an external combustion engine in contrast to an internal combustion engine where the heat input is by combustion of a fuel within the body of the working fluid. Unlike the steam engine's use of water in both its liquid and gaseous phases as the working fluid, the Stirling engine encloses a fixed quantity of permanently gaseous fluid such as air or helium. As in all heat engines, the general cycle consists of compressing cool gas, heating the gas, expanding the hot gas, and finally cooling the gas before repeating the cycle.
