Project description:

The analysis of larger sample quantities (5 g), e.g. in the case of substitute fuels, by means of a rapid test is currently not possible for maintaining and ensuring the required quality standards. Instead, time-consuming and therefore cost-intensive procedures such as the determination of chlorine and the calorific value by coulometry, as well as the analysis of ash content and moisture, must be carried out gravimetrically. This is a situation that causes considerable costs for the operators of refuse-derived fuel power plants. The joint development should for the first time result in a functioning prototype for the complete gas analysis of refuse derived fuels with large sample volumes. By developing a suitable gradient furnace in combination with the required sample transport technology, a new gas flow system to be developed and IR detection for chlorine, water and carbon dioxide, it should be possible to analyze all the required parameters in a single system. As a result, the first complete analysis system for refuse-derived fuels is to be created as a world first. The project was successfully completed at the end of October 2011.
