Abstract
Liquid accumulators which substantially include several or at least one type of energy generation, such as heatable to almost the temperature of fresh air by solar irradiation with the thermal supply of circulation heat, by refuse combustion with the recovery of waste heat, by recovery of waste heat from exhaust gases in the case of heating boilers and generators, and also usable in a continuous process for the production of biogas from small refuse in the sewage.
Claims6
A heat accumulator comprising
- (a) a container for a liquid heat transfer medium,
- (b) heat insulation surrounding the container and heat-insulating the container from the ambient atmosphere,
- (c) a combustion chamber in the container, the chamber receiving combustion air,
- (d) an exhaust ventilator arranged to exhaust gases from the combustion chamber,
- (e) a counter-flow heat exchanger surrounding the combustion chamber, the exhaust ventilator being arranged to cause the exhaust gases to flow therethrough for pre-heating the combustion air in the combustion chamber, and
- (f) a heat-insulating pad surrounding the combustion chamber for heat-insulating the liquid heat transfer medium from the combustion chamber.
