Abstract:
The present invention relates to a gasification burner comprising a main burner, N-stage sub-burners arranged on the inner side of the main burner, where N is an integer greater than or equal to 1, the main burner and each stage of the sub-burners have independent fuel channels and oxidant channels respectively, the main burner and each stage of the sub-burners are arranged in a coaxial sleeves from outside to inside; the inner diameter of the main burner is larger than the outer diameter of the first stage of the sub-burners, and the inner diameter of each stage of the sub-burners is larger than the outer diameter of its next stage of the sub-burners; the gasification burner can ensure fuels and oxidants to be mixed fully and evenly in limited reaction space and residence time, accelerate combustion reaction rate, thereby improving fuel conversion rate and gasification performance; meanwhile, it can flexibly adjust flame shape without reducing the load of gasifier furnace by adjusting the load of the main burner and each stage of the sub-burners, thereby effectively avoiding overheating of the gasifier furnace to meet different production load requirements of project sites.
Abstract:
A burner assembly combines oxygen and fuel to produce a flame. The burner assembly includes an oxygen supply tube adapted to receive a stream of oxygen and a solid fuel conduit arranged to extend through the oxygen tube to convey a stream of fluidized, pulverized, solid fuel into a flame chamber. Oxygen flowing through the oxygen supply tube passes generally tangentially through a first set of oxygen-injection holes formed in the solid fuel conduit and off-tangentially from a second set of oxygen-injection holes formed in the solid fuel conduit and then mixes with fluidized, pulverized, solid fuel passing through the solid fuel conduit to create an oxygen-fuel mixture in a downstream portion of the solid fuel conduit. This mixture is discharged into a flame chamber and ignited in the flame chamber to produce a flame.

PROBLEM TO BE SOLVED: To provide a biomass center air jet burner for power generation which satisfies requirements with respect to development of an effective and efficient alternative means replacing coal combustion and a means capable of spreading combustion of a carbon-neutral fuel in power generation applications. SOLUTION: A burner throat 4 for passing air and fuel supplied to a burner assembly 1 and for discharging them into a furnace 3 is connected to the furnace 3. Core air 5 which is a part of secondary air 22 enters a core air duct 6, is adjusted by a core air damper 7, is continued via a core nozzle 8 through the burner assembly 1, and gets out of the core nozzle 8 via the burner throat 4. The secondary air 22 moves through an inner air zone 10 and an outer air zone 11, and is turned by a turning vane. In this way, ignition and combustion of the secondary air 22 which contacts a pulverized coal stream is facilitated. COPYRIGHT: (C)2011,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a novel recyclable energy source using, as a fuel, aluminum which can be stored easily and fed stably without harming environments or human bodies.SOLUTION: An energy generated as a result of a steady combustion of an aluminum powder and oxygen introduced into a combustion chamber is retrieved and utilized. The steady combustion of aluminum is executed by controlling either or both of the quantity of the aluminum powder and the quantity of oxygen introduced into the combustion chamber. The quantity of the aluminum powder is controlled by controlling the quantity of an aluminum powder swept by and taken into a carrier gas jet used for introducing the same powder into the combustion chamber or by controlling quantities of impurities mixed with the aluminum powder. The quantity of oxygen is controlled by controlling the mixing ratio thereof with a concomitantly introduced diluting gas. The alumina generated as a result of combustion is recovered, and aluminum obtained by reducing the former can be recycled as a fuel.
