SU95144A1 - Gas generator for low grade fine grain fuel - Google Patents

Description

The subject of the invention is a gas generator for a low grade Me.iKO3epfii-icToro fuel with a tangential gas flow and top fuel.

The specific feature of the gas generator, according to the invention, is that by enhancing the temporary residence of the fuel particles in the gas generator and their more complete gasification, the generator has a sectional step about the chamber in the dispersed but supply zones blown through dyes of tuyeres located in the nodoscopies of the contiguity of adjacent sections.

We propose that the gas generator shown schematically in the drawing consists of calgers / gasification and chamber 2 of carbon recycling of particles carried by the gas note. Chambers have oi-non-refractory lining. In place between the chambers, a blown position is set at c 3 with tann-rationally naravanny nozzles for supplying superheated steam or other reagent, CTByioaiero method for carbonization of carbon in particles carried by the gas note from the meter / gasification.

the chamber / gasification lining of the product in the form of several sections, including truncated cones, with the exception of the upper cone 4, with a smaller base downwards 5, 6 and 7; The number of these sections is chosen constructively, according to the design.

To the lower cone, an ash removal sleeve 8 is suspended, through which the ash in its sonic state is removed from the α-generator by one of the well-known methods.

Each section of the gasification chamber has a series of tangentially oriented tuyeres located in the contact plane of two adjacent sections.

The gas tonnage used for gasification is supplied by a highly superheated water bunker with the help of a feeding device to the upper section of the gasification chamber 4 through two or three tangential 10 tuyeres located.

Due to the vortex motion in the dust-gas stream but around: the chambers / gasification sections 4, the fuel is heated in the vapor-gas atmosphere to the nouxing stage and releases volatile components, which are removed together by the gas flow and enter the chamber 2 Md. in the gas cleaner.

As the supply of new portions of fuel, the excess of poke of fuel is displaced -. from the upper section of the cone 4 and enters the zone of the stationary sections 1 1, through the tangent gas. It is used to receive air chambers that supply air, steam, natural mixture, or air that is heated by air.

The presence of horizontal gaps between the sections ensures a sufficient residence time of the particles in the sections, which creates predosostotsi zo, ozhu vygig u1 electrode of fuel particles up to 3 mm in size.

The gas flow, lifting up, is shifted with fresh fuel in the upper section 4, which ensures proper thermal preparation of the top seam and warming up the particles to a temperature of 15 ° C.

The top.piva particles carried away from the gas stream by a stream are separated from the gas-vapor mixture into a dust separation unit and, if necessary, can be returned to one of the gasification chamber sections.
