JET GASIFIER AND A METHOD OF CONTROLLING ITS OPERATION

The important characteristic of the construction of the jet gasifier consists in that it includes among others the dry steam generator (SG) supplied from the outside, a steam superheater (SS), an injector jet pump (IJP), a system for feeding the ground mass to be gasified (MFS), a reaction chamber (RC), a cooler (CO) a separation system (SEP), a combustible gas container (CGC), valves, to include safety valves, and various meters and sensors, in particular temperature and pressure meters and sensors, and an electronic control system, and that these components are connected hydraulically is such a way that the steam outlet from the dry steam generator (SG) is connected, preferably through an electrically controlled pressure reducing valve (PRV), with the inlet of the steam superheater (SS), and its outlet is connected with the supply nozzle (nozzle propeller) of the injector jet pump (IJP), and its inlet port is connected through an electronically-controlled stop valve (SV) with the ground mass outlet in its feeding system (MFS), while the outlet port of the injector jet pump (IJP) is connected, preferably with a flange packing (P), with the inlet of the reaction chamber (RC), which has the shape, preferably, of a spiral coil, in particular of a vertical cylinder, as shown on drawings no. 1-5, whose upper opening constitutes the chamber's inlet and the lower opening - its outlet, and the outlet of the chamber (RC) is connected, preferably with a flange packing (P), with the inlet of the cooler (CO), and the outlet of the cooler (CO) is connected with the inlet port of the separation system (SEP), while the outlet of the purified cooled mix of combustible gases from the system (SEP) is connected through a check valve (CV) with the combustible gas container (CGC), and the electronically controlled valves located in the aforementioned components and the electronic meters and sensors, in particular pressure and temperature meters and sensors, are electrically connected with the electronic control system, and, moreover, the hydraulic connections between the individual components of the gasifier and the reaction chamber (RC), and the housing of the jet pump (IJP) are lined with a layer of thermal insulation, and the components that are exposed to high temperatures are made from high-temperature creep resistant materials, preferably from superalloys, and, moreover that the sections of the components through which flows the stream of steam and gases produced in the
