Unitary auxiliary electric power, steam supply and heating plant for building construction

Claim 1

A compact unitary, transportable, auxiliary steam turbine driven electric generator power and heating plant comprising: a generally closed rectangular enclosure including opposed vertical end walls and opposed vertical sidewalls and a top wall spanning the upper ends of said sidewalls and endwalls, a plurality of vertically spaced, horizontal partitions within said enclosure forming at least first, second, third, fourth and fifth separate compartments in ascending order, at least some of said partitions being formed of heat insulative mateRial, a fuel air mixture combustor carried within said first compartment, a boiler heat exchanger coil extending transversely within said second compartment, a plurality of horizontally spaced, vertical conductive walls within said third compartment, manifolds at either end of said conductive walls and forming therewith a combustion air preheater heat exchanger, a first condenser heater heat exchange coil extending transversely within said fourth chamber, a steam turbine driven electric generator within said fifth chamber, first conduit means fluid coupling said boiler heat exchange coil, said steam turbine and said first condenser coil and forming a closed loop path therebetween, first duct means within said partition separating said first and second chambers to effect flow of exhaust gas from the combustor over the boiler heat exchange coil and through said second chamber, second duct means within the partition separating the second and third chambers to direct exhaust gas after passage over the boiler heat exchange coil into the third chamber, an exhaust pipe fluid connected to said third chamber at the end of said chamber opposite that carrying said second duct means, an air inlet opening within an end wall of said enclosure at said fourth chamber introducing fresh air therein for passage over said condenser coil, third duct means extending through the partition separating said third and fourth chambers for directing heated fresh air into said third chamber for counterflow to and sealed from the exhaust gas for further preheating the combustor intake air, and fourth duct means within said third chamber at the end opposite that carrying said exhaust gas discharge pipe for receiving the preheated fresh air and conducting said preheated fresh air to said first chamber for intake by said combustor.
