    Abstract: A two part heat recovery unit receives a high temperature gas mixture (2) in the lower, refractory-lined dwell furnace (4) wherein the gas is cooled to condense out liquid inert ash material. The cooled gas mixture exits the dwell furnace (4) vertically upward through a transistion duct (18) which includes a restricted throat (28). Additional ash and potassium seed compounds condensed from the gas mixture in the convective furnace (20) either form a loose flyash which exits the convective furnace (20) with the gas mixture via the backpass (24), or collect on the walls and heat transfer surfaces (22) of the furnace (20) as a liquid which runs downward toward the throat (28) and is there reentrained by the high velocity gas stream.

    Abstract: The water flow circuit for a heat recovery steam generator is a hybrid system which combines a circulating drum type circuit and a once-through circuit. A low pressure evaporator is designed for natural or forced circulation and a high pressure evaporator is designed for once-through flow. Orifices may be located in the inlet of the evaporator tubes for flow stability and an intermediate header between the evaporator and high pressure superheater improves stability, minimizes orifice pressure drop and equalizes pressure losses between evaporator tubes.

    Abstract: The flue gas temperature coming from an air preheater to a particulate collection device such as an electrostatic precipitation or fabric filter is reduced to improve the operation of the particulate collection device. This may be done by reducing the exit flue gas temperature from the air preheater or reducing the temperature after exiting. In one embodiment, air in excess of that needed for combustion is passed through the air preheater with the heated excess air either being dumped or used for a variety of purposes in the plant. A particular embodiment involves segmenting the air outlet side of a rotary regenerative air preheater and withdrawing the excess air from the segment where the dust loading is the lowest. Further, additional cooling of the flue gas can be provided by reducing the quantity of primary air that typically bypasses the air preheater and then providing other ways to control the primary air temperature to the pulverizers. The flue gas temperature may also be cooled after the air preheater by heat exchange or spray cooling with water.

    Abstract: A coal fired power plant includes the catalytic reduction of NO.sub.x in the flue gas and the catalytic oxidation of SO.sub.2 to SO.sub.3 followed by the hydration of the SO.sub.3 to H.sub.2 SO.sub.4 vapor and then the condensation to H.sub.2 SO.sub.4 liquid. The condensation takes place in a wet sulfuric acid condenser by heat exchange with incoming combustion air. A portion of the heat picked up by that combustion air is used to provide a portion of the heat for the condensate from the steam turbine. The combustion air is then fed to an air preheater and to the steam generator as primary and secondary combustion air.

    Abstract: A magnetohydrodynamic topping unit is added to a pre-existing fossil fuel steam generating plant by a system of conduits and a chamber which show the high velocity output gas of the generator, attenuate oxides of nitrogen, reduce the temperature of the channel output gas, and initiate recovery of seed material. The connecting system is arranged to recover heat from the output gas of the MHD channel by absorbing this heat in the feed water system of the steam generator. The addition of the MHD channel to the existing steam generator provides an alternate source of heat for the steam generator.
