RDF combustion plant at Gatwick airport.

This waste-to energy project, which is the perfect example of circular economy, was born as an answer to the growing problem of waste generation that exists in developed countries. In recent years, there has been a change from landfill to waste recovery, with the objective of replacing fossil fuels with those commonly known as RDF (Refuse derived fuel).

The company DHL, which was selected to manage this waste at Gatwick airport (United Kingdom), opted for the recovery of the solid waste generated in the catering of the planes and converted it into a refuse derived fuel (CDR). For this purpose, it contracted the services of Tidy Planet and Sugimat.

The turnkey system (EPC) designed consisted of the installation of an industrial thermal oil boiler with a travelling grate combustion chamber adapted to refuse derived fuel (RDF), also called CSR (Solid Recovered Fuel).

It also has a RDF furnace or combustion chamber with automatic cleaning and automatic combustion regulation. All this is done by means of the computer vision system to attend to the variation in the characteristics of the fuel.

The control software is specifically designed by Sugimat for the project. It allows a perfect optimization and control of the combustion, favouring the energy efficiency.

In addition, for this design Sugimat had to adapt its equipment to the incineration directive (WID). For this purpose, it was necessary to design a gas permanence chamber.

The installation is contracted to operate for more than 8,000 hours per year and has an automatic cleaning system as well as a ceramic filter to meet emission limits.

The plant provides heating for the buildings, as well as drying of the RDF to achieve the optimum humidity targets for the process.
