ABSTRACT:
An apparatus for heating a liquid by mixing combustion products therewith comprises a housing having a liquid reservoir compartment, a mixing chamber above the reservoir having a tortuous fluid flow path, a combustion chamber above the mixing chamber with a gas burner and apparatus for igniting and burning a mixture of air and fuel and an apertured water jacket at the upper end. A pump draws liquid from the reservoir and discharges it through the water jacket on the combustion chamber side wall to cool the burning mixture. The discharged liquid collects at the lower end of the combustion chamber and flows evenly throughout the tortuous fluid flow path (Raschig rings) in the mixing chamber to thoroughly mix hot combustion gases with the hot liquid mixture for maximum heat transfer. The mixture falls through an air space into the reservoir to separate the excess gases for venting to atmosphere. The heated liquid may be circulated through a hot water supply piping system for industrial usage. A coil submerged in the reservoir allows a second liquid to be heated thereby for use in a hot water supply system for residential or industrial usage. A second coil installed in the combustion chamber and coupled to the lower coil allows higher temperatures to be achieved.
