Description

 The invention relates to fuel industry and is intended

thermal processing of solid fuels, in particular, oil shale,

with whole production of tar and gas.

The closest solution to is; known is a gas generator for heat treatment of solid fuels, including a vertical case, means for loading fuel installed in its upper part along the vertical axis, and means for unloading hard residue, located in the lower part of the case, burners installed in the walls of the case, a vapor-gas collecting chamber rectangular mixtures with lid and latrubkom for removal of steam

Gyz mixture located inside the body along its vertical axis.

The disadvantage of the known generator is low computable use of its volume, since the size of the chamber for collecting the gas-vapor mixture must be more than enough to avoid dust being carried away from the gas generator, which leads to a decrease in tazogontoratoo performance; -: In addition to the TorOj, the location of the nozzle for removal of the gas-vapor mixture in the collection and removal chamber of the gas-vapor mixture does not allow the circulation gas to heat the upper layers of the fuel, which also reduces the productivity of the gas generator The aim of the invention is to increase the production capacity and gas generator and reduction of ash dust. This goal is achieved by the fact that in a gas generator, including a vertical Koprfyc, a means for launching the upper part of the first section along the vertical section, for unloading the remaining balance, is located at the top of the floor, the floor of the floor, the floor of the floor. a heat sink, a ycfaHSmfeHitkbte in the walls of the housing, a vapor-gas mixture chamber with a cap located inside KopTiyca along its vertical axis under the loading means, and a branch pipe to drain the vapor-gas mixture, a branch pipe for discharge of the gas mixture iiapo is located in the upper part but. -. ., i; j .. - An additional difference of the gaser is that the Chamber collect the gas mixture of a cylindrical shape; -, Tayoy location of the pipe for removal of the gas-vapor mixture and the expansion of the chamber for collecting gas and fumes , na1figo2 - on pepper cut; on a fig. dvd on a 11th burner burner, .., the gas generator includes a spiral housing 1, made of fire material, a device for loading fuel 2, which has been installed in the upper part of the housing 1 along its vertical axis, means for uchch- chf- -. A solid solid residue (not conventionally shown in the drawing) is located in the lower part of the body, 3 for the purpose of obtaining and maintaining heat, i Inside the Corlus 1 on the metal trusses 4 a chamber 5 is fixed to collect the vapor-gas mixture, which is a grating cylinder. On top of the chamber 5 is closed with a conical knuckle 6 burners 3 are equipped with nozzles 7, 8 and 9 for the supply of gas, air and. The gas flow rate, respectively, is located in the walls of housing 1 in several Russ. The number of runes and the number of burners 3 in the house are selected because of the possibility of controlling the flow and temperature of the gas by the height of the gas generator and its even distribution in the cross section of the fuel layer, Kalda burner 3 is connected to the distribution manifold 11f made in the machine chambers using the chimney 10 cross section 1 with the help of distribution grilles. Distribution grids 12 are made of a durable material. In the lower part of the housing 1 there are means 13 and 14 for supplying circulating gas. and the purpose of cooling the solid residue processing. and, if necessary, an oxidizing agent; , -. In the upper part of the bulkhead 1 is located the pipe 15 dx / vapor-gas mixture. - l Fuel (() is loaded with device 2 into the working building, 1 o To burners 3 feed gas and gas (respectively through pat .-, cabins 8 and 7) to obtain heat transfer fluid from the burner 3 from the burner 3 to the heat carrier circulating gas For regulating the temperature of the coolant in I given limits (500-900 C)., the burner 3 of the lower rus, if necessary, can be used to supply oxidizing agent For the gasification of semi-coke (for example, vapor-air, smoke-air, or tenth gases), Heat carrier from burners 3 and smoke stoves 10, p distribution manifolds 1 1 and gratings 12, uniformly propellant a layer of fuel in the transverse direction, which causes shale coking. By virtue of the filtering ability of the indicated layer, the gas-and-gas mixture is cleaned of shale dust, collected further in the upper part of the furnace, unfilled, and drained through the device ystvo 2 kondensaE ion system.

The solid residue of the processing enters the lower part of the housing 1, where it is cooled with reverse circulating gas to the BW-C, which is introduced into the housing 1 by means 13 and 14. The solid residue is unloaded by special devices (not shown in the drawing) and sent to dump

Due to the presence of a layer of fuel above the chamber for collecting the vapor-gas mixture.

1 16294. with the ability to carry away from the steam-gas shale dust, it creates the possibility of a dramatic reduction in the discharge of shale dust from the furnace

  This will reduce the diameter of the cylindrical chamber for removal of the gas-vapor mixture and thereby increase the effective volume of the semi-coking shaft and, therefore, increase the shale volume.
