Abstract

See full text

One embodiment of the present invention is a boiler for boiling water to produce steam, having (1) an evaporating section comprising (a) a combustion chamber for burning fuel with air and generating hot flue gas, (b) an evaporating heat exchanger around the combustion chamber for exchanging heat between the flue gas and water to produce the steam which exits the boiler; and (2) a condensing section comprising (c) a condensing heat exchanger for exchanging heat between the hot flue gas from the combustion chamber and a low-temperature water return having a temperature below approximately 100° F., generating flue gas condensate, which leaves the boiler, wherein the low-temperature water return is heated by the hot flue gas in the condensing heat exchanger before entering the evaporating heat exchanger for additional heating. The disclosed vacuum condensing boilers make vapor vacuum steam more efficient and economical for industrial, commercial, and home applications.
