Micro-combined heat and power (mCHP) systems: Heat Call Process

Back

When there is a call for heat, the burner fires and starts the Stirling generator, producing about 25% of the full heat output.

Front

Function of the Burner in mCHP Systems

Back

The burner pre-heats the return system water, and hot flue gases pass across the heat exchanger to heat the system further.

Front

Supplementary Burner in mCHP Systems

Back

If there is more demand for heat, the supplementary burner ignites.

Front

Operation of the Stirling Engine

Back

The Stirling engine uses the expansion and contraction of internal gases to operate the piston without explosive combustion.

Water conservation is essential due to increased demands on water supply systems from population growth.

Back

True, as population growth increases demand on water supply systems, making water conservation crucial.

Uses of potable water include drinking, washing, bathing, and watering gardens.

Back

Potable water is used for drinking, washing, bathing, and watering gardens.
