An electric power generating system and method of operation is comprised of a waste-heat boiler adapted to a Rankine cycle provided with turbines for driving an electric generator. The waste-heat boiler uses exhaust combustion products from a fuel-fired device as a thermal heat source for vapor regeneration of an organic heat exchange fluid mixture used in the Rankine cycle.

A fuel cell stand-by energy supply system is provided for supplying electrical power to a device operated by power from an electrical utility in the event of a power failure. The system is comprised of a microcontroller which is connected to a detector capable of detecting power failure. The microcontroller monitors this detector and one or more conditions of the device to which electrical power is fed. The microcontroller operates a fuel cell switch to connect the fuel cell d.c. supply directly to the d.c. device or to a voltage conditioning circuit to produce an operative a.c. supply which is connected to the device to continue operation thereof during the power failure. The microcontroller monitors and manages the load in relation to the fuel cell power. The microcontroller also performs an autodiagnostic of the fuel cell.

An integrated air conditioning and hot water supply system for conditioning air and supplying hot water to a building is described. The system incorporates a hot water tank in the system which feeds a heat exchanger to heat air which is recirculated from the building when required during cool weather periods. A combined air dehumidification device and cooling device are also provided to dehumidify and cool return air from the building in a recirculation circuit when required by the building during warm weather periods. The cooling devices incorporate coils connected to the city water supply whereby to preheat a supply of water to the hot water tank. The combined circuit also cools fresh air and treats it to provide a source of heated air to regenerate a desiccant wheel which is used as the dehumidification device. A heat recovery ventilator is also incorporated in the integrated system to treat exhaust air from the building during cool weather periods and to admit warmed fresh air thereto.

An oxygen-enriched gas burner and method of operation thereof for incinerating and/or melting and/or vitrifying and/or performing thermal treatment and/or oxidizing ground/liquid waste materials and particularly, but not exclusively, contaminated waste materials. The burner comprises a body having annular chambers and defining an injection nozzle which is adjustable whereby to adjust the configuration of a flame and wherein the nozzle is provided, at the center thereof with an axial feed port through which the grounded solid/liquid waste material is injected within the flame. The waste material is fed axially within the flame under control pressure with the waste feed and flame configuration being adjusted independently from one another whereby the waste material is substantially incinerated without substantially affecting the combustion of the gas which would otherwise produce undesirable carbon monoxide and hydrocarbons.
