STIRLING ENGINE MICRO CHP SYSTEM

Objective

The project aims to demonstrate the viability of CHP on the smallest possible scale for the residential and small commercial market. It is intended to adapt existing Stirling Engine technology from its automotive application and to demonstrate its suitability for CHP production.
Altough the economic criteria for CHP are most difficult to achieve on an individual installation at this scale, the potential for replication makes this the most attractive market both in commercial terms and in the interest of society as a whole.
The aim is to demonstrate reliability in use, economic and efficient performance with low enegry costs and pollutant emissions.

The Stirling Engine Micro CHP is to be installed in four demonstration site. Two of the buildings are representative of the anticipated market (residential and small commercial) with sufficient diversity to highlight and overcome the potential obstacles to widespread replication. The other two sites are larger and will allow a range of operational requirements to be simulated. The SE-CHP unit comprises a natural gas fired Stirling engine driving a single or three phase operation. The gas burner is at the "hot" end of the Stirling engine with the "cold" end at a mean temperature of 70C. The latter is connected to the flow and return pipes of the radiator central heating system and provides the heat input to the dwelling for space heating and domestic hot water purposes in the same way as the currently installed gas boiler.
The generator is connected to the electrical distribution mains within the dwelling and meets the majority of the electrical load of the dwelling. Surplus generation capacity and peak load (e.g. when the CHP unit is made for the balance in summer) is supplied from the network and is metered. A credit is made for the balance imported and exported electricity at different rates.
