Inspirit Charger

The Inspirit Charger has been developed over a number of years and is based upon a patented kinematic Stirling engine generator module. The Stirling engine, a virtually frictionless system powered by gas burner heat, drives a generator to produce up to 3kW of mains voltage electricity and is capable of exporting this electricity back to the utility grid via the UK’s G83 connection protocol.

Unlike an internal combustion engine where combustion takes place inside the cylinder, Stirling engines are “external combustion engines” operating at high efficiencies. The cycle is sealed and contains a constant volume of the working gas, inert and safe helium. The cycle works by expanding and contracting the volume of gas caused by temperature differentials at either end of the engine and hence the engine has a hot end and a cold end. The heat source is provided by the gas fired burner, used for central heating and for transmitting heat through a heat exchanger to the volume of gas in the engine. Cooling is supplied by water cooled heat exchangers taking the original heat away for use in the central heating system.

Heat produced by the combustion process has a number of uses: preheating of the incoming air/fuel mix, generation of electricity and heating of the water circuit.
