    supply of fuel oil and a pipeline for supplying fuel oil to the collector with a heating jacket located above the surface of the water, while the heating systems are inclined to the vertical axis of the housing.
    The supply of fuel oil leads to the formation of large particles of slag with an average weight consisting of the weight of floating particles, as a result of which the immersion of all particles of slag is impeccable.
    Heavy particles due to their combination with floating lighter particles are immersed with the latter.
    If one adds fuel oil in an amount of 1 by weight of slag, then the production process should be interrupted on average after 3 weeks, and when oil is added in an amount of% by weight of slag, the production process is interrupted on average only after 1.5 months.
    An increase in the amount of added fuel oil to 5 by weight of slag leads to an abrupt, lengthening of the production period, i.e. The suspension of the process takes place only after 8 months. The increase in the amount of added fuel oil from 5 to 15% by weight of slag leads to the fact that production should be interrupted only after about one month.
    The addition of fuel oil in the amount of 26-20% by weight of slag is not associated with a further noticeable lengthening of the production period.
    FIG. 1 is a diagram of the installation for gasification; in fig. 2 node 1 in figure 1; in fig. 3 pipe with heating jacket.
    The device includes a gas generator 1 with a pump 2 and a pipeline 3 for supplying a suspension of coal and water.
    In the lower part of the gas generator 1 there is a cooling chamber comprising a body k with water 5. A collector 6 with nozzles 7 for fuel oil supply and a pipeline B for supplying fuel oil to the collector 6 with a heating jacket 9 are located above the surface of water 5.
    The device works as follows.
    In the gas generator 1 is fed through the pump 2 through the pipeline 3 suspension of coal and water. Coal
    dust is obtained P (1FORLTI; 1M,
    neither in the mill 10. After grinding, no coal dust enters with the water in the mixer 11. From the bottom of the mixer 11 it is continuously removed
    suspension of coal and water. Together with the suspension of coal and water through a 12-in. Pipeline. gas generator 1 serves oxygen. At a temperature of about and a pressure of about 30 bar, synthesis gas is obtained from coal, oxygen and water vapor. This synthesis gas consists of carbon monoxide and free hydrogen.
    The resulting synthesis gas from the gas generator enters the cooling chamber below it. Slag particles also enter the cooling chamber along with the gas. This slag is first produced in liquid
    form and collect on the surface of the water
    5in the lower part of the body k,
    In the cooling chamber, the first cooling of the obtained synthesis gas is carried out. For this purpose, the cooling chamber is provided with a pipe 13. for. cooling water and pipe 1 for removal of the heated mixture of steam and water. The cooling water supply pipe 13 enters the ring pipe 15, from which a plurality of cooling pipes 16 are evenly spaced around the circumference.
    In addition to the cooling pipes 16, a pipe AND is connected to the ring pipeline for the removal of a mixture of steam and water. The pipe I is located diametrically to the pipe 13 for supplying cooling water to the ring pipe 15 and has a consistent cross-section with the cooling pipes 1b such that the flow of the cooling medium in the cooling pipes 16 is not disturbed by the continuous removal of water through the pipe k.
    Through pipe 8 to the collector
    6 Feed heavy fuel oil. From the collector 6 tons of heavy fuel oil passes through a set of evenly spaced nozzles 7 onto the surface of the water 5. Nozzles
    7 are so large that only compact fuel oil jets arise, which prevents it from igniting and reduces losses.

    Fuel oil is added to the fluidity necessary for flow through the collector 6 and the pipeline 8 and passing through the nozzles 7 by preheating in the heating jacket 9 and subsequent heating in the annular collector 6. Through the pipe 17 for waste a for the synthesis gas produced in the generator 1 from the cooling chamber. Synthesis gas is subjected to controlled cooling in order to avoid undesirable reactions. For the necessary cooling associated with the preheating of the fuel oil, the cooling is too low. Therefore (the exhaust gas is still cooled in the waste heat boiler The day is shown) cooled by water. The vapor generated together with the vapor generated in the cooling chamber is used for any purpose. Thus cooled, the synthesis gas is then treated with water. The treatment is carried out by spraying. At the same time, undesirable ash impurities are removed from the synthesis gas. Then, the mixture of water and ashes obtained by flushing the waste gas removes the water obtained during the condensation to the treatment and the remainder of the mixture with the feed material in the gas generator. This mixing of the slag with the feed material improves the high temperatures required for gasification. The slag that collects in a water bath in the ka попа falls into the gateway 18 located under the cooling chamber and is collected there until the gateway reaches a certain degree of filling. Then the gateway 18 closes and the slag formed during the operation of the gas generator generates at the entrance to the gateway. After closing the inlet of the gateway 18, the exit of the gateway 18 opens and the slag can be removed from the gateway 18 with a low operating pressure without disturbing the required working pressure of the generator. 0 The location of the nozzles obliquely to the vertical axis of the body allows the fuel oil jets to move the slag particles falling on the surface of the water bath to the middle of the bath to meet each other. The separated slag portions are intensely. on the other hand, so that fuel oil, as a binder, manifests its optimal effect. Claim 1. Method of removing slag produced by gasification of solid carbon-containing fuel, including the supply of liquid slag to water and the subsequent removal of the solid particles of slag, characterized in that, in order to improve the performance of the process, the preheated fuel oil in the amount of the weight of the liquid slag.
