  Method and device for the direct generation of water vapor by the
Heat from glowing solids such as coke, slag and ash.
 EMI1.1
 Glowing coke, slag and ash or the like. Is obtained in water. The accompanying drawing shows schematically an embodiment of the device used for this in a vertical section.



   The glowing coke or d. A red-hot slag is poured through a funnel T into a container R which is lined with a heat-insulating material. From this container the coke or slag is then transferred to a boiler C below by any known device
 EMI1.2
 Screw A into a paternoster plant E creates. The paternoster is surrounded by a watertight sheet metal shell and the height of the water column in the sheet metal shell corresponds to the level of the steam pressure occurring in the boiler. The scoop buckets of the paternoster plant are perforated so that the water they lift flows back into the shell.



   The water in the boiler C heats up and the pressure of the gases and steam developed in the process pushes the water located under the plate or channel through the pipe B into the high-level evaporation space V, where it partially evaporates. The steam generated here is removed through the perforated pipe n, while the water that is not needed is conveyed back into the boiler by the centrifugal pump P and the pipes a and b. The small amount of water vapor that has to be let out through the pipe (in order to remove the gases that continuously accumulate in the steam boiler C, is continuously removed and brought to the condensate in the feed water tank - for the boiler.

   The water preheated in this way is passed through a pipe t connected to the suction pipe a of the pump P into the steam boiler. The valve drawn in line a is used to regulate this outflow by adjusting it so that the desired pressure in boiler C is maintained.



   The paternoster plant is open at the top and the solid materials that have been raised by it,

   Pipe <into the steam boiler C.



   In the process described, the glowing solid substances give off their heat to the water directly and in the simplest way with a very high degree of efficiency. In this way one can also extract the salts that may be present in the slag and in the ashes; they are in solution in the water of the steam boiler. The steam obtained contains only a small amount of gas and can be used for heating or for generating motor power.



   The present device is very simple and any metal can be used for its B1u. The force required for operation is only a small part of that generated.

Claims (1)

PATENT CLAIMS: 1. A method for the direct generation of water vapor by the heat of glowing solid substances such as coke, slag and ash, characterized in that the gases that develop when the substances mentioned are mixed with the water to be heated, immediately in addition to a little steam from the container , by doing <Desc / Clms Page number 2> the substances mentioned with the to. come into contact with heating water, while the heated water is transferred to a second container, where pure steam develops from it. 2. Device for carrying out the method according to claim 1, characterized by a container (R) lined with a heat insulating material for receiving and uniformly feeding the glowing material into a boiler (C) arranged below, in which a screw conveyor (A) rotates in order to feed the quenched material to a jacketed bucket elevator (E) and from which the hot water is transferred to a high-level boiler (V) from which it is pushed back into the boiler (C) after the steam has been released by a pump (P), EMI2.1
