<p>The disclosure describes a slag bath generator operating under pressure and constructed as a vertical and substantially cylindrical shaft, and having a central arching of the base to act as a slag overflow. Nozzles are directed towards the bath surface and are intended for introduction of the fine-grain fuel and the gasification media. The direction of the jet of the nozzles disposed in the shaft wall forms an angle of about 35 to 40.degree. with the horizontal, and the nozzles are so distributed that the points of impingement of the jets formed by them on the slag bath surface are situated on a number of concentric circles extending around the axis of the shaft. With this angle range, there is obtained a maximum acceleration effect on to the surface of the bath which is distributed over the entire surface of the bath. Moreover, the nozzles are so disposed that the angle formed by the jet impinging on the slag bath surface to the tangential plane of the relevant circle, which tangential plane is vertical at the point of impingement on the surface, is about 10.degree. towards the side remote from the slag outlet. As a result, a radial force in the direction of the central slag overflow acts on the bath surface.</p> |
