ABSTRACT:
To simplify control, decrease start-up time and improve efficiency, a heat storage device is provided connected to receive hot combustion gases from a burner, the heat storage device preferably including a vessel which contains a substance changing in phase between solid and liquid, and being heated by the exhaust gases from the burner. A heat pipe is in heat transfer relation to the substance, extending in a predetermined direction, and ducts, pipes or conduits conducting the combustion gases from the burner extend in parallel to the heat pipe, through the substance, or surrounding a vessel containing the substance. Preferably a group of heat storage units are joined to common inlet and outlet manifolds connecting combustion gases, arranged such that the flow speed of combustion gases further downstream is higher than that further upstream, to equalize heat transfer and hence storage capability and storage times of the individual units.
