Description

one

The invention relates to the field of engineering of the building materials industry, namely to vapor-gas mixture generators for the heat-moisture treatment of concrete products.

A known generator of a vapor-gas mixture, including a furnace for burning fuel and producing combustion products, heats the water through the metal heating surface and the chamber, where the produced steam is displaced with the combustion products of water 1.

The closest technical solution to the invention is a double-circuit gas water heater, including a furnace, a contact chamber with an irrigator and a nozzle, a heat exchange chamber with a water jacket) 2.

A disadvantage of the known devices is the inability to provide a high efficient adiabatic evaporation mode of the heated water.

The purpose of the invention is to provide heat and moisture treatment of reinforced concrete products.

This is achieved in that the water heater is equipped with a mixing chamber and a gas duct with a socket in the lower part connecting it with a contact chamber, a smoke exhauster installed at the outlet of the mixing chamber, and pipelines connecting the water jacket with the contact chamber and the latter with a sprinkler.

FIG. 1 shows the proposed water heater, a general view.

The water heater contains a steam chamber 1, a smoke exhauster 2 for supplying the gas-vapor mixture to the steam chamber, a mixing chamber 3 into which combustion products flow through the duct 4, the sprinkler 5 supplying water to the nozzle 6 of the contact chamber 7, pipeline 8 with a pump 9 for supplying water to the sprinkler from the lower part of the contact chamber, the rotary regulating gate 10 in the flue 4, the lower part of the flue, made in the form of a bell 11. The fuel is burned in the burner 12. Tortik 13 covers the walls of the furnace 14, surrounding with a water jacket exchange chamber 16. The water on the jacket is connected to the lower part of the contact chamber by pipeline 17.

The water heater works as follows.

Claims (2)

Water from the heating systems is fed into the water jacket from below, heated and removed from the top, directed to the heating systems. A portion of water is supplied through conduit 17 to the lower part of the contact chamber, and from there through conduit 8 to the irrigator 5. In the contact chamber 7 on a fixed grating or in a layer of movable hollow balls, a highly turbulized foam layer is formed, in which highly efficient heat exchange occurs between the combustion products and water, leading to its evaporation and complete saturation of the combustion products with vapor. The saturated gas-and-gas mixture is removed by a smoke exhauster into the mixing chamber, where, if necessary, combustion gas is fed through the gas duct 4, which, mixing with the saturated gas-vapor mixture, reduces its relative humidity and leads to its overheated condition. The invention will improve the efficiency of the water heater by 10-12% compared with surface type boilers. Claims of the invention Double-circuit gas water heater including a furnace, a contact chamber with an irrigator and a nozzle, a heat exchange chamber with a water jacket, characterized in that, in order to bleed the heat and moisture treatment of concrete products, it is equipped with a mixing chamber and a gas duct with a flare at the bottom connecting the it with a contact chamber, a smoke exhauster installed at the outlet of the mixing chamber, and pipelines connecting the water jacket with the contact chamber and the latter with the irrigator.
