Abstract: A system and method deliver fluidized powder based on flue gas carrying waste slag and instant cooling steel slag. A first flue gas pipeline receives pressurized CO2-rich flue gas and in fluid communication with a fluidization air pipeline, a pressurization air pipeline and a supplementary air pipeline respectively and through them enters an upper discharge bin; a second flue gas pipeline receives the pressurized CO2-rich flue gas and in fluid communication with a gas-gas mixer, a dense phase discharge guide pipe first end extends into the upper discharge bin and receives high-pressure dense phase gas-powder flow of CO2-rich flue gas, and a dense phase discharge guide pipe second end is connected to the gas-gas mixer; a variable-pitch twin screw sealed conveyor discharge end extends into an upper discharge bin internal space, and is provided with an upwardly inclined gas-blocking segment.

Abstract: A burner includes a housing, a fan, a burning head and an ignition mechanism. An air inlet of the housing and an input end of the burning head form a pressure equalizing cavity. The ignition mechanism is arranged at an output end of the burning head. The burning head includes a main frame and at least one stable burning isolation strip, an interior of the main frame is divided into at least two ventilation areas by the stable burning isolation strip in a gas channel direction. A plurality of separation mechanisms is arranged in each ventilation area and divide the ventilation area into a plurality of through holes arranged in the gas channel direction, the through holes are used for allowing mixed gas to pass through and strengthening the mixing effect. The burning flame of a burning surface of the main frame can be divided into mutually independent flames by the stable burning isolation strip.

Abstract: A burner contains a burner component. The burner component includes a main frame and at least one stable burning isolation strip. An interior of the main frame is divided into at least two ventilation areas by the stable burning isolation strip in a gas channel direction. Several separation mechanisms are arranged in each ventilation area and divide the ventilation area into several through holes distributed in the gas channel direction. The through holes are used for a mixed gas of fuel gas and air to pass through and enhancing a mixing effect of the fuel gas and the air. The flame of a burning surface of the main frame can be divided into independent flames by the stable burning isolation strip so that the burning is more stable and fewer pollutants are emitted.

Abstract: A catalytic flameless combustion apparatus has a fuel inlet, a combustion-supporting gas inlet, a gas premixer, a combustion plate, an igniter, a gas deflector, a flameless combustion cavity, a catalyst filled in the flameless combustion cavity, a gas collection chamber and an exhaust port. The method for starting the catalytic flameless combustion apparatus includes initially combusting and heating the flameless combustion cavity and the catalyst filled therein with low power flame; and then increasing flow velocity and switching to high power flame for conducting catalytic flameless combustion. The catalytic flameless combustion apparatus can be used for various non-solid fuel combustion and heat extraction processes.

Abstract: The present application relates to the field of electric motor, particularly to a motor rotor structure with copper conductive bars. This application aims at solving the problem existed in the art, which is how to reduce stress concentration of the rotor iron core and how to avoid deformation of the copper end rings. The motor rotor structure of this application comprises a rotor iron core provided with rotor slots, copper conductive bars provided within the rotor slots, rotor end rings respectively provided at two ends of the rotor iron core. Each rotor end ring includes copper end rings and steel end rings. The copper end rings are alternately laminated with the steel end rings and welded together into a piece.
