JET GASIFIER AND ITS CONTROL METHOD

According to the present invention, the important characteristic of the construction of the jet gasifier (drawing no. 1) consists in that it includes, among others, a dry steam generator (SG) supplied from the outside, a steam superheater (SS), an injector jet pump (IJP), a system for feeding the fragmented mass to be gasified (MFS), preferably biomass, a reaction chamber (RC), an ejector jet pump (EJP), a water pump (WP), a separation and cooling system (SCS), a combustible gas container (CGC), valves, to include safety valves, various meters and sensors, in particular temperature and pressure meters and sensors, and a control system, and that these components are connected is such a way that the steam outlet from the dry steam generator (SG) is hydraulically connected, preferably through electrically controlled pressure reducing valve (PRV1), 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 hydraulically connected with the fragmented mass outlet in its feeding system (MFS), while the outlet port of the injector jet pump (IJP) is hydraulically connected, preferably with a flange packing (P), with the inlet of the reaction chamber (RC), which can have the shape, preferably, of a spiral coil, in particular of a vertical cylinder, as shown on drawings no. 1-3, whose upper opening constitutes the chamber's inlet and the lower opening - its outlet, and the outlet of the chamber (RC) is hydraulically connected, preferably with a flange packing (P), with the inlet port of the ejector jet pump (EJP), and the supply nozzle (nozzle propeller) of the ejector jet pump (EJP) is hydraulically connected, preferably by an electrically controlled pressure reducing valve (PRV2), with the outlet of the water pump (WP), while the outlet port of the ejector jet pump is hydraulically connected with the inlet of the separation and cooling system (SCS), and the outlet of the purified and cooled mix of combustible gases from the system (SCS) is connected through a check valve (CV) with the combustible gas container (CGC), while the outlet of purified and cooled water from the system (SCS) is hydraulically connected with the inlet of the water pump (WP), 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
