The reusable warmers of the present invention also maintain a substantial degree of flexibility during their useful heat cycle.

Biomass was also used for heat production (16,980 TJ).

Heat pumps enable the efficient supply of useful heat, including environmental heat (ambient air, ground).

with or without the ability to recover useful heat;

The heat has to be produced at the site pressure and temperature levels required for the specific useful heat demand or market.

with or without the ability to recover useful heat.

Hcog is the annual consumption of useful heat from cogeneration in the year i

To make it clear, the écocompressor recovers fatal heat and convert it into useful heat and compressed air.

Conversion of the biogas to renewable electricity and useful heat with cogeneration / combined heat and power

This is what makes heat helpful in this individual scenario.

A closed cycle heat transfer device comprising a boiler (10) and a condenser (13), the condenser being used to recover useful heat by latent heat evaporation.

Carnot efficiency (fraction of exergy in the useful heat).
