ZVU Engineering is one of the few companies in the world that for long time period is involved in the industrial application of coal into the high grade gaseous fuel. The industrial application of the Czech pressure coal gasification started early in the fiftieth of the last century when former ZVU Hradec Králové Companies, together with Czech research and design institutes, developed its own pressure coal gasification process and key equipment that were applied and installed in several gasification plants, as listed below.
ZVU Engineering, as successor of the former ZVU, has assumed full know-how of this process that was collected through development activities as well as through industrial applications of the gasification plants, like Pressure Coal Gasification Plants in Úžin and Vřesová (Czech Republic) and Lanzhou (China), and that is the base for the current industrial applications.
ZVU Engineering’s key references:
