摘要： A reheat-and-regenerating type thermal power plant (A) using Rankine cycle has a water feed bypass (BW) which suppies high temperature fluid (28) produced in a large incineration plant (27) to a heat exchanger (29) and by which confluent feed water (Wg) resulting from the confluence of separated condensed-water (32), separated low temperature feed water (33), separated medium temperature feed water (34) and separated high temperature feed water (35) is supplied to a superheat conduction pipe (3a) through a heat exchanger conduction pipe (29a). The water feed bypass (BW) is installed separately from a feed water path (W), thus insuring an efficient use of the high temperature fluid (28) produced upon incinerating a huge amount of combustible wastes in the large incineration plant (27).

摘要： The invention relates to a method and an arrangement in the production of electric energy in a boiler plant of a pulp mill. Black liquor having a dry solids content of more than 80% and combustion air are fed into a furnace of a recovery boiler for combusting black liquor and recovering chemicals contained therein. The flue gases generated in the combustion are led into an economizer of the recovery boiler, in which economizer the feed water for the boiler is heated, and after the economizer to gas cleaning. The feed water is led from the economizer onto the steam-generating bank at a temperature below the saturation temperature and further into a superheater to produce steam having a pressure of more than 80 bar. The steam is led from the recovery boiler to a steam turbine to produce electricity. The temperature of the feed water being led into the economizer is regulated by means of bleed steam of the turbine so that the flue gases exit the economizer at a temperature of more than 250° C. and that after the economizer the flue gases are cleaned in at least a hot electrostatic precipitator and the cleaned flue gases are cooled by the combustion air or the feed water.

摘要： A method of selective catalytic NOX reduction in a power boiler and a power boiler with selective catalytic NOX reduction. Fuel is combusted in a furnace of the boiler and a flue gas stream that includes NOX is generated. The flue gas stream is conducted from the furnace along a flue gas channel to a stack. The flue gas stream is cooled in a heat recovery area, including an economizer section, arranged in the flue gas channel. At least a portion of the NOX is reduced to N2 in an NOX catalyst arranged in the flue gas channel downstream of the economizer section. The flue gas is further cooled, and heated air is generated in a gas-to-air heater arranged in the flue gas channel downstream of the economizer section and upstream of the NOX catalyst. The gas-to-air heater may be a tubular air heater or a heat exchanger with a recirculating heat transfer fluid.

摘要： A combined-cycle power generation system using waste matter as a fuel, which can be expected to improve in power generation efficiency without using an additional fuel. The system has a corrosive exhaust gas source (waste exhaust gas source) (1), a closed-cycle gas turbine (2), and a Kalina-cycle steam turbine (3). A ceramic heat exchanger (6) for the closed-cycle gas turbine (2) is disposed on a high-temperature side of the corrosive exhaust gas source (1). A heat exchanger (7) heats a mixed ammonia water fluid (11) for the Kalina-cycle steam turbine (3) by a high-temperature side exhaust gas from the closed-cycle gas turbine. A heat exchanger (9) evaporates a condensate of the mixed ammonia-water fluid (11) by heat remaining in the exhaust gas from the closed-cycle gas turbine. A heat exchanger (10) for the Kalina-cycle steam turbine is disposed on a low-temperature side of the corrosive exhaust gas source (1) to evaporate the mixed ammonia-water fluid (11) by heat remaining in the waste exhaust gas.

摘要： A combined cycle waste-to-energy plant is utilized to thermally convert municipal and industrial solid wastes into essentially complete products of combustion and use the combustion heat to produce steam and/or electrical power. The plant includes a building enclosure having a waste receiving area, a waste fuel separation and processing area, an incinerator area and a heat recovery and power generation area. Processed waste fuel is delivered to a series of incinerators by an automated conveyor and hopper system, and the waste fuel is burned in the incinerators by hot exhaust gas delivered thereto from one or more combustion turbines located outside the building and drivingly connected to electrical generators. Inlet air to the turbines is drawn from with the building to maintain its interior at a negative pressure, thereby preventing waste odors and pathogens from escaping from the building. Hot combustion turbine exhaust gas delivered to the incinerators is passed through a superheater, and a portion of the exhaust gas exiting the superheater is passed through a waste heat recovery boiler. Hot combustion gas discharged from each of the incinerators is passed through an associated combusion heat recovery boiler. Gas heat recovered in the superheater and the various boilers is utilized to produce steam which operates a steam turbine drivingly connected to an electrical generator. A portion of the steam generated may also be used for process purposes.
