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.

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.

The selective catalytic reduction of nitrogen oxides to nitrogen is effected by reacting nitric oxide, nitrogen dioxide or a mixture thereof with a reducing agent consisting of an aliphatic carboxylic acid having 1 to 5 carbon atoms at a temperature ranging from about 250.degree. to, about 600.degree. C., in the presence of a catalyst comprising a metal oxide selected from the group consisting of vanadium oxide, copper oxide, nickel oxide and iron oxide, the catalyst being supported on a porous carrier. The process of the invention enables one to substantially completely reduce NO.sub.x to harmless N.sub.2 in an efficient, environmentally friendly and cost-effective manner.
