    This application describes a process and apparatus for gasifying sulphur bearing coal in a molten iron bath which is covered with a sulphur absorbing slag. In order to make the process practical, the hot liquid slag is transferred to a second vessel in which it is desulfurized by contact with an oxygen containing gas, and then returned as hot liquid slag to the iron bath for reuse.

    2. Method of pop., Replying with the fact that slag desulfurization is carried out with a mixture of oxygen with an inert gas.
    3. A device for gasification of sulfur coal in iron melt, having a gasification chamber with molten iron, Containing coal, oxygen-containing gas and slag supply means, slag desulfurization chamber with oxygen-containing gas supply unit located in the lower part of the chamber, slag removal channel From the gasification chamber to the slag desulfurization chamber and the channel for returning the desulfurized slag to the gasification chamber, characterized in that the channel for the removal of slag from the gasification chamber is connected directly to the chamber re-desulfurization is made expanding in the middle part.
    The invention relates to the processing of sulfur coal, in particular to the method of gasification of coal in iron alloy and to a plant for its implementation, and can be used in the coal industry
    The known method of gasification of sulfur coal in the heat carrier melt, for example, slag, includes supplying coal and water vapor to the heat carrier melt and subsequent coal gasification, removing the heat carrier melt from the gasification zone and heating it with heated air, heating the heated melt ihe heat transfer agent to the gasification zone i.
    A device for the gasification of sulfur coal containing a gasification chamber with a molten coolant, a melt heater of a heat carrier, a channel connecting the gasification chamber and a heater located below the surface of the slag bath, a channel for returning the heat carrier from the heater to the gasification chamber equipped with an overflow device, devices for it transportation l.
    A disadvantage of the known method and apparatus is the production of synthesis gas of unsatisfactory quality.
    The closest to the invention to the technical essence and the achieved effect is the method of gasification of sulfur coal in the molten iron, including the supply of coal and oxygen-containing gas to the melt
    and subsequent coal gasification, removal of the slag formed, slag granulation and desulfurization with oxygen-containing gas, supply of desulfurized slag wa the molten iron surface 2,
    A device for the gasification of sulfur coal is known, comprising
    molten iron gasification chamber, having means for supplying coal, oxygen-containing gas and slag, slag desulfurization chamber with a nozzle for supplying oxygen with an oxygen-containing gas located in the lower part of the chamber, channel for removing slag from the gasification chamber to the desulfurizing chamber slag into the gasification chamber. A granulator and a cooling device zj are located between the gasification chamber and the slag desulfurization chamber.
    The disadvantage of this method and
    5 of the device is that as a result of the granulation and cooling, the heat content of the waste slag is lost, which negatively affects the energy consumption of the process.
    In addition, the granulation and cooling of the slag being removed complicates the process.
    The purpose of the invention is to reduce energy consumption and simplify the process.
    This goal is achieved by the fact that, according to the sporobu of gasification of sulphurous coal in iron melt, which includes supplying coal and oxygen-containing gas to the melt and subsequent gasification of coal, withdrawing the molten liquid slag and scattering it with oxygen-containing gas and supplying the desalted molten slag to the surface of the vessel. the liquid is subjected to slag and supplied to the gasification stage in a liquid state. Slag desulfurization is carried out with a mixture of oxygen and an inert gas. - In the device for gasification of sulfur coal, having a gasification chamber with molten iron, containing means for supplying coal, oxygen-containing gas and slag, a slag desulfurizing chamber with an oxygen-containing gas nozzle located in the lower part of the chamber, a channel for slag removal from the gas chamber to the slag desulfurization chamber and the channel for returning the desulfurized slag to the gasification chamber, the slag removal channel from the gasification chamber is connected directly to the desulfurization chamber and the expansion CMs in the middle. Such an implementation of the method and implementation of the device reduces the energy consumption and simplifies the process by eliminating slag from the granulation and cooling. Figure 1 shows the device section; FIG. 2 is a section A-A in FIG. U The device contains a gasification chamber 1 with molten iron, having means 2-4 for supplying coal dust, oxygen-containing gas and lime dust. Shpak is retracted through channel 5, which is made expanding in the middle part and around the quiescent chamber 6. Channel 5 connects gasification chamber 1 to chamber 7, desulfurizing slag that is removed through channel 5. Cast iron droplets separated in the stilling chamber 6 are returned to the gasification chamber 1 through channel 8. The chamber 7 for desulfurizing the liquid slag is equipped with a nozzle 9 for supplying oxygen-containing gas, and a device 10 for supplying the sugar-free slag to the recirculation channel 11 (Fig. 2) which can be provided with a drain for removal of part of the recycled liquid slag. Example 1. In the gasifier reactor with a capacity of 28, m, containing 30 tons of molten iron with a content of 3% carbon, 50 t / h of coal dust containing 5% ash and 3% sulfur, 100 kg / h of oxidation oxide and oxygen in the shell are fed propane in an amount to provide a melt temperature of 1350-1450s. Shlg.C is formed on the surface of the melt in an amount of 10 t / h, fed to the desulfurization with oxygen-containing gas, and the resulting desulfurized slag (final sulfur content 0.001%) is recycled to the gasifier in an amount of 5 tons / h. 100,000 meters of synthesis gas, consisting of 80.5% carbon monoxide and 19.5% hydrogen, are each hourly removed from the gasifier reactor. Example 2. Example 1 is repeated with the only difference that the sweet slag is fully recycled to the gasifier reactor. At the same time receive 100000 m / h synthesis gas composition of 80.3% carbon monoxide and 19.7% hydrogen. Compared with the known method in which the hot slag is granulated and cooled and partially recirculated when cooled, the proposed method makes it possible to reduce energy consumption by about 1.5-10 kcal / h.
