Problems solved by technology

Therefore, regardless of coal or plant powder, once it comes into contact with the air compressed by the propeller above 195.35°C, some of the substances in the coal tar or wood tar will burn, and some of them will incompletely burn to produce soot. Part of it will melt and adhere to the inner wall or nozzle of the distribution air supply tube, which will easily cause blockage
Therefore, to use the above-mentioned prior art to import plant powder and coal powder into the burner of an open-cycle gas turbine system for combustion as a fuel for driving vehicles, ships or power generation, it is obvious that oil stains and soot in the small fuel powder distribution pipe must be removed frequently. very troublesome

Abstract

The invention discloses a powdery solid fuel combustion and work application method and a powdery solid fuel combustion and work application device. Powdery solid fuel is input into an open cycle gas turbine system for combustion by utilizing an airtight helical feeder, and enters a gas turbine to be expanded and apply work to generate power, wherein the airtight helical feeder is provided with a device which prevents a high-pressure combustion gas from being leaked outwards from a combustor along a rotating shaft of a helical fin in an airtight shell.

Description

technical field [0001] The invention relates to a method and device for solid fuel powder combustion and work, in particular to a method and device for feeding plant, coal and other solid fuel powder into a burner in an open-cycle gas turbine system through a closed screw feeder, which can be quickly and safely , Efficient combustion to generate power method and device. Background technique [0002] The existing U.S. Patent No. 2,601,309 is a method for inputting solid coal powder into a burner in an open-cycle gas turbine system for combustion to generate power. The brief description is as follows: After the coal is ground and sieved, the powder is mixed in the air and is distributed by a distributor ( The impeller (Impeller) in the distributor (or called divider) sucks the air from the large conduit (Conduit) into the vent hole in the center of the impeller in the distribution chamber, and then is compressed by the machine into many small distribution supply pipes uniforml...
