摘要： The invention relates to a burner arrangement for a combustion chamber (12) in addition to an associated combustion chamber (12), in particular a gas turbine combustion chamber or a steam generator combustion chamber, comprising a plurality of burners (8), which are equipped for the combustion of fuel which contains carbon by supplying pure oxygen, which is effective as an oxidation agent. The aim of the invention is to obtain a burner arrangement which has a particularly high energetic degree of efficiency and particularly low residue emissions and at the same time maintains the construction and operation thereof simple and economical and reverts to suitable fuelling concepts. Also, the acceptable material temperatures of the encircling walls (6) surrounding the combustion chamber (12) must not be exceeded. The inventive first burner (8) is embodied in such a manner that the ratio (?), per time unit, of the amount of oxygen guided therein, in normal operation, for the stochiometrically required amount of oxygen is greater than for a second burner (8) which is arranged downstream from the direction of the flow of flue gas (14).

摘要： An improvement of a combustion furnace for a boiler in which it is possible to improve and uniformize the heat collection ratio of the furnace of the boiler. Moreover, this invention easily controls the temperature of superheated steam while the heating surface area is kept constant without altering the boiler construction and heat balance, and provides a zone temperature control to a boiler. The boiler according to the present invention is provided with a radiant heat transfer portion (15) in which at least one or more heat accumulating type burner systems are disposed in which a pair of burners (2, 3) for suppyling air for combustion and exhausting combustion gas through a heat accumulator (5) are caused to burn in an alternate fashion while combustion gas is discharged through the heat accumulator (5) from one of the burners which is not burning, so that excess heat energy that has not been consumed in the radiation heat transfer portion (15) is recovered when it is exhausted via the heat accumulator (5) of the other burners. In addition, in the boiler of the present invention, a plurality of heat accumulating type burner systems (1) are disposed in a direction in which water for the boiler flows, and the pair of heat accumulating type burners (2, 3) of the respective burner systems (1) are disposed in a direction that intersects the direction in which water for the boiler flows, whereby a temperature zone is formed by controlling combustion for each heat accumulating type burner system (1), thereby making it possible to control the distribution of the furnace heat collection ratio. Furthermore, the boiler of the present invention has the radiation heat transfer portion (15) in which at least one heat accumulating type burner system is provided, and is provided with a superheater (17) in which saturated steam is superheated by extracting a part of combustion gas from the radiation heat transfer portion (15), the combustion gas being exhausted directly out of the combustion chamber without passing through the burners (2, 3).

摘要： A method and apparatus for recovering sensible heat from a hot exhaust gas having an oxygen concentration of less than 21 vol% in a fuel-air fired combustion device. An oxidant stream comprising a gas having an oxygen concentration of greater than 21 vol% is introduced into the combustion process to form an oxidant mixture comprising the hot exhaust gas, the oxidant and any air present, the mixture having an average combined oxygen concentration of less than 21 vol%.

摘要： An arrangement and method in a boiler using fluidized-bed technology. The arrangement comprises a first space (1) of a furnace that comprises means for forming a fluidized bed (21), a second space of the furnace that does not comprise means for forming a fluidized bed, means for feeding fuel into the first space (1) of the furnace, a partition wall (3) that is at least mainly vertical and arranged between said spaces (1, 2) of the furnace to separate them from each other, the arrangement further comprising a roof structure (5) arranged above the first space of the furnace to separate the first space (1) of the furnace from parts of the second space (2) above it, the first space (1) of the furnace being connected to the second space (2) through a flow path (18), which flow path (18) is arranged on the side of the first space (1) of the furnace to lead gases (G) rising from the fluidized bed to the second space (2) of the furnace.

摘要： A method of combustion and an apparatus therefor in which separate streams of very lean and very rich fuel/oxidant mixture are combusted separately, the products of combustion therefrom being thoroughly mixed before final combustion takes place. The lean/rich primary combustion minimises combustion temperatures and pollutant formation, whilst the final combustion is substantially stoichiometric.
