Plant Concept
General information
Conceptually, TCP Energies offers to utilize high-calorific residual materials by means of our patented innovative technology in an ecologically and economically highly efficient way in order to generate electricity for the company's own use and/or to feed it into the public grid.
Technical implementation
The basic technical implementation is as follows: Material reception and material processing (conditioning), thermal area with a WGL 2-50 (two Waste Gasification Lines) with gas treatment and electricity generation area. Conveyors are used to transport the accumulated and collected residual materials to the material preparation area of the plant, where they are pre-conditioned in accordance with the process requirements. This is followed by thermochemical treatment in the two gas lines. The combustible and engine-compatible fuel gas produced is then converted into electricity in gas Otto engines and ORC systems. The plant concept includes all main and auxiliary units required for proper operation as well as all storage tanks for operating and auxiliary materials. The design and installation are carried out in accordance with the applicable regulations and standards for the construction and operation of such a plant. The interfaces are:
