    An improvement in a radiation boiler for cooling a gas stream containing solid and molten particles wherein gas is introduced vertically via a gas feed at the top of a radiation boiler having a cooled gas outlet and a water bath disposed at the bottom thereof for removing the particles after they have been solidified and cooled. Between the gas feed and the water bath are disposed at least two concentrically arranged cylindrical tubular heat exchange elements vertically disposed in the boiler and forming at least one annular passage therebetween. The passage through the innermost heat exchange element is in fluid flow registry and fluid flow communication with the gas feed. A conical deflector has the axis thereof coincident with that of the innermost heat exchange element and thereby in registry with the flow of gas passing through the passage through the innermost heat exchange element and is disposed toward the bottom of the radiation boiler above the water bath but at least partially below the lower end of the innermost heat exchange element, whereby gas which strikes the conical surface of the conical deflector is deflected and passes through the at least one annular passage and in the passage of the innermost heat exchange element.

    : o with eo: A9 with HncifipeTf-HHo refers to cleaning a chop, and concerns, in part, the device for the pistachio and the hot gases from the hard and fusible parts. The closest to the proposed technical essence and the achieved result is a device for cleaning hot gases from solid and fusible particles, containing a vertical case with a water bath in the lower part, gas inlet and outlet pipes located in the upper part of the body sludge offtake, placed under the water bath mounted at a distance from the hull wall, equipped with a cooling water supply system, and a conical insert with a nozzle-tip located in the lower part of the housing, npiweM in a funnel-shaped collector is installed in the water bath, the outlet of which is located above the outlet nozzle l. A disadvantage of the known device is the difficulty of concentration. The purpose of the invention is to simplify the design while maintaining the maximum degree of purification. In order to achieve this goal, in the device for cleaning hot pots of solid and fusible particles, containing a vertical case with a water bath in the lower part, gas inlet and outlet pipes, located in the upper part of the case, a pipe for sludge removal, placed under The bath is mounted at a distance from the walls of the hull with a spudifier equipped with a system for supplying a cooling water tank and a conical insert with a nozzle-tip located in the lower part of the hull, and a funnel-shaped collection is installed in the water bath The outlet of which is located above the sludge discharge pipe, the cooler is made in the form of at least two coaxial cylindrical shells, the gas nozzle pipe is installed above the cooler while the shells are equipped with cleaning masks. The drawing shows a device for cleaning hot gases from solid and fusible particles. The device is made in the form of a vertical cylindrical body with a water bath in the lower part. The core nvc 1 has pltrubki 2 for H1:) a hot gas dam, pa-1trubok 3 for sludge removal, a fitting A for evacuating the cleaned gas, a cooler including heat exchange elements 5 and 6 in the form of cylindrical shells equipped with a pipeline 7 for supplying a cooling medium , pipe 8 for removal of production steam, as well as nozzles 9 for cleaning the surfaces of heat exchange elements 5 and 6, mounted cooling cone insert 10 eccentrically above the bath surface, on top of which a cleaning nozzle tip 11 is installed, and a funnel Ovoobny collection 12, installed in a water bath. Cleaning nozzles 9 through pipe 13 and valve 14 are connected to a tank 15 for a cleaning medium, preferably gas, and a compressor 16. Pipeline 13 is provided with a bypass 17 for supplying cooling medium to the nozzles. The insert 10 is provided with a pipeline 18 for supplying cooling water and a pipeline 19 for discharging the production gas. The nozzle 11 is provided with a pipe 20 for supplying water. The device works as follows. The gas stream to be cleaned enters the body 1 through the central nozzle 2 parallel to its axis and flows vertically downwards with a slight radial component. Larger fusible particles of ash are not captured and are not thrown to the walls of the heat exchanger elements, but fall onto a cooled conical insert 10, which, being interconnected with the water bath underneath, causes a deviation of the gas flow, and smaller ash particles, entrained by the gas stream, are thrown into the water bath. Due to the conical insert, a narrowing of the cross section of the flow is created, as a result of which the gas flow rate increases accordingly. Placing the nozzle 2 over the cooler allows to increase the degree of gas purification and prevent the nozzle clogging with fusible particles. When a layer of particles adheres to the cooler, it can be cleaned by supplying water to the cleaning nozzles 9. The gas is discharged through pipe 3. Thanks to the described constructive discharge (due to the annular space between the cooler's elements), the gas flow rate in the pressure in the gas outlet pipe decreases significantly resulting in a further reduction in the ash content. ycrafioBKcn additional final concentrating chillers: the chiller shells the gas flow can be further cooled and more shelled.
