ABSTRACT:
This invention relates to method and apparatus used as an addition to any existing heating system--burning any fuel--for heat recovery from stacks and chimneys. It uses a suitable heat exchanger mounted at the apex of such stacks, by virtue of which location no natural draft is lost. The system includes a circulating pump, a thermostat, an expansion bottle, a condensate trough, a cap and dome which jointly serve to act as unloaders to protect the system liquid from being boiled off. Both sensible heat and the latent heats of moisture in the fuel and in the vapor produced as a combustion product, can be scrubbed out. The use is to effect economies and to reduce environmental contamination wherever fuels are fired.
