摘要： In a preheating steam generator, the feed water is distributed in a feed space (34) by inverted J-shaped tubes (50), so as to mix with the recirculation water passing out of the water-steam separators, which ensures the preheating of said feed water. In order to prevent the latter rising again above the upper edge (30a) of skirt (30) externally defining the space (34), use is made of one or more of the four procedures consisting of partly obstructing by a plate (52) the top of space (34), downwardly extending tube (50), increasing the diameter in the vicinity of their end and upwardly extending skirt (30).

摘要： A fluidized bed steam generating system in which a duct is disposed between a furnace outlet and a separator inlet. The duct is formed by first and second wall panels which are comprised of a plurality of parallel tubes extending perpendicular to the direction of the flow of the combustion gases. The tubes comprising the wall panels are bent and welded to a fin extending from corresponding portions of adjacent tubes to form a gas tight structure. The ends of the tubes are connected in fluid flow communication with first and second headers which enables cooling fluid to flow through the tubes for recovering heat from the combustion gases as they flow from the furnace into the separator.

摘要： A fluidized bed combustion method in which a recycle heat exchanger is located adjacent the furnace of the combustion system. A mixture of flue gases and entrained particulate materials from a fluidized bed in the furnace are separated and the flue gases are passed to a heat recovery section and the separated particulate material are passed back to the furnace. The walls of the furnace are formed by water tubes, and refractory metal material is placed adjacent the walls to control the heat absorption by the water passing through the tubes. The amount of refractory is selected in accordance with the desired operating temperature of the furnace.

摘要： A reactor in which a furnace and a heat recovery area are provided. A bed of solid particulate material including fuel is supported in the furnace and air is introduced into the bed at a velocity sufficient to fluidize same and support the combustion or gasification of the fuel. The products of combustion (or flue gases) pass upwardly through the furnace and transfer heat energy to the walls thereof to produce steam. Flue gases leaving the upper region of the furnace section are transported to a heat recovery area, which functions to remove additional heat energy from the flue gases for producing the steam. A flue gas by-pass system is provided which transports relatively hot flue gases from a lower region of the furnace section to the heat recovery area for improving isothermal operating conditions and optimizing reactor performance. One or more conduits pass flue gases directly from selected extraction points within the lower region of the furnace to an upper portion of the heat recovery area. A dust collector may be connected to the gas extraction conduits for separating particulate material from the flue gases, if needed.

摘要： A reactor in which a bed of particulate material including fuel is formed in one of two sections in a vessel. Air is passed through the bed at a velocity to fluidize said material and promote the combustion of the fuel. The air and the combustion gases mix and entrain a portion of the particulate material, and pass from the one section to the other section. A plurality of spaced parallel water tubes are disposed in the path of the mixture and entrained particulate material as they pass through the other section to separate the entrained particulate material from the mixture.

摘要： The production of water vapor is controlled in a plant for combusting fine-grained and dustlike solid fuels together with air in a combustion zone of a heat exchanger in the upper region of the combustion zone, a water vapor accumulator, which communicates with the heat exchanger, and a water vapor feed line leading from the water vapor accumulator to a turbine. The rate at which water vapor is produced is continually calculated and is compared with the desired value which is required by the turbine and the rates at which fuel and combustion air are supplied to the combustion zone are adjusted in accordance therewith. The combustion plant may comprise a fluidized bed cooler for cooling a part of the part of the combustion residue. That cooler may comprise a plurality of chambers provided with heat exchangers for an evaporation of feed water or for a super heating of water vapor. Any water vapor which is produced from feed water in said chambers will also be taken into account in the calculation of the total rate at which water vapor is produced in the combustion plant.

摘要： An improved steam generator having an auxiliary recirculation path in its secondary side is disclosed herein, as well as an improved method for mixing wet lay-up chemicals therein. The invention is particularly applicable to nuclear steam generators of the type including a secondary shell that contains a quantity of water, a bundle of heat exchange tubes, and a tube wrapper that concentrically surrounds the tube bundle for defining a downcomer path. The auxiliary recirculation path allows the water present within the tube wrapper to circulate through the downcomer path when the water level within the secondary shell is lowered below the upper edge of the tube wrapper during maintenance operations. The auxiliary flowpath, when used in combination with nitrogen sparging, allows wet layup chemicals injected into the downcomer path of the generator to be rapidly and uniformly mixed throughout the entire water inventory in the secondary shell, thereby minimizing generator downtime and radiation exposure to maintenance personnel.
