摘要： A method and apparatus are provided for operating a pressurized reactor system (1) in order to precisely control the temperature within a pressure vessel (3) in order to minimize condensation, and to prevent the temperature from reaching a detrimentally high level, while at the same time allowing quick heating during start-up. Gas is circulated from one part of the inside volume to another to control the temperature of the inside volume, for example by passing the gas through an exterior conduit (7) which has a heat exchanger (8), control valve (9), blower (10) and compressor (11) associated therewith, or by causing natural convection flow of circulating gas within one or more generally vertically extending gas passages, containing heat exchangers, flow rate control valves or the like, entirely within the combustion vessel. Preferably, inert gas is provided as circulating gas. The inert gas may also be used in emergency shut-down situations, when reaction gas supply to the reactor is cut off, and inert gas is introduced into the reactor.

摘要： Hot gases from a pressurized fluidized bed reactor system are purified. Under superatmospheric pressure conditions hot exhaust gases are passed through a particle separator, forming a filtrate cake on the surface of the separator, and a reducing agent - such as an NOx reducing agent (like ammonia), is introduced into the exhaust gases just prior to or just after particle separation. The retention time of the introduced reducing agent is enhanced by providing a low gas velocity (e.g. about 1-50 cm/s) during passage of the gas through the filtrate cake while at superatmospheric pressure. Separation takes place within a distinct pressure vessel the interior of which is at a pressure of about 2-100 bar, and introduction of reducing agent can take place at multiple locations (one associated with each filter element in the pressure vessel), or at one or more locations just prior to passage of clean gas out of the pressure vessel (typically passed to a turbine).

摘要： A pressurized fluid bed reactor power plant includes a fluidized bed reactor (6) contained within a pressure vessel (5) with a pressurized gas volume (21) between the reactor and the vessel. A first conduit (16) supplies primary gas from the gas volume to the reactor, passing outside the pressure vessel and then returning through the pressure vessel to the reactor, and pressurized gas is supplied from a compressor (2) through a second conduit (4) to the gas volume. A third conduit (8, 11), comprising a hot gas discharge, carries gases from the reactor, through a filter (9), and ultimately to a turbine (1). During normal operation of the plant, pressurized gas is withdrawn from the gas volume through the first conduit and introduced into the reactor at a substantially continuously controlled rate as the primary gas to the reactor. In response to an operational disturbance of the plant, the flow of gas in the first, second, and third conduits is terminated, and thereafter the pressure in the gas volume is substantially reduced by opening pressure relief valves (19, 20) in the first and third conduits, and optionally by passing air directly from the second conduit to the turbine.

摘要： A pressurized fluidized bed reactor is provided utilizing a centrifugal separator having a gas space that is distinctly non-circular, preferably having a circularity of greater than or equal to 1.15. Most desirably the cyclone has a quadrate (e.g. square) cross section, and is disposed inside the pressure vessel along with the reactor chamber containing the fluidized bed. A number of ceramic candle or honeycomb filters may be provided connected to the gas outlet from the cyclone separator, within the pressure vessel, to filter the gas. This construction provides a minimized diameter of the pressure vessel because the reactor chamber with square cyclones is more compact than if conventional circular cross section cyclones are employed. Also a second pressure vessel is not needed for the candle or honeycomb filters since there is sufficient room within the pressure vessel to accommodate them.

摘要： A method and an apparatus for conveying particulate material of a reactor pneumatically from a high pressure delivery vessel (10) to a receiving vessel (40) at a lower pressure using gas discharging from the reactor as a carrier gas, by using an apparatus comprising a conveyor line (20) and a collecting vessel (30), which collecting vessel comprises means (50) to discharge carrier gas and means (54) to control the flow rate of the carrier gas, in which the pressure in the collecting vessel is controlled in such a way that the material has almost the same pressure as the delivery vessel when conveyed to the collecting vessel, from which it is transferred to the receiving vessel essentially at the same pressure as the receiving vessel.

摘要： The present invention relates to a combined cycle power plant comprising an air compressor (1), a gas turbine (5), a pressure vessel (11) and a pressurized circulating fluidized bed (CFB) reactor (10) enclosed by the pressure vessel. The CFB reactor includes a reactor chamber (12), means for leading hot combustion gases away from said reactor and one or more non-circular centrifugal separator(s) (13) for receiving and purifying the hot combustion gases. Disposed within the pressure vessel is further a bubbling fluidized bed heat exchanger chamber (12') in communication with the reactor chamber (12) and sharing a common wall section with said reactor chamber.
