Abstract
Abstract A combined exhaust manifold and boiler unit for employing the hot exhaust gases from an engine to vaporize liquids such as the effluent from a septic tank with secondary heating coils available for vaporizing the liquid when the engine is not running. The unit either may be an integral or split housing of aluminum construction which maximizes heat transfer and minimizes manufacturing costs.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
193 words
An extruded evaporator unit for use with a fuel-burning engine having an exhaust system through which waste heat passes, said extruded evaporator unit comprising; an elongated housing having a bottom wall and spaced-apart sidewalls integral with said bottom wall to define a passageway, said housing having open end portions, said passageway having a substantially uniform cross-sectional area from one end to the otHer of said housing, a top wall formed integrally with said sidewalls, a pair of end walls attached to said end portions of said housing to form a first chamber in said housing, a second chamber formed with said housing on top of said top wall, said end walls including adapter means for connecting said exhaust system to said first chamber so that waste heat flows through said chamber, an outlet in said first chamber for waste heat flowing therethrough, connecting means for connecting said second chamber to a source of liquid to be vaporized, a steam outlet in said second chamber, at least one bore formed through one of said sidewalls and extending into said top wall, and electric heater means positioned in said bore for heating said top wall.
