New Gas Cooler for Continuous Emission Monitoring Systems According to EU 15267

Since January 6. 2011, emissions from combustion plants within the European Union must be continuously monitored according to the stipulations of European Directive 2010/75/EU of November 24. 2010.

The automatic emission monitoring systems required must comply with EN 14181 which comprises three quality classes. These systems follow the intention to monitor the emission levels across the European Union by uniform standards. Consequently, only analysis systems which are approved and certified to EN 15267 are acceptable.

To ensure that the sample gas remains unchanged all the way down from the source to the analyser, all wetted components involved must not react with, or wash out, components of the gas. Before they can be installed,  these systems are tested according to EN 15267-3 and certified. Later modifications or changes may need additional approval.

The new TC-Double gas cooler, recently lauched by Bühler Technologies (Germany) fully complies with EN 15267. The TC-Double runs the sample gas through a cooling cascade created by two thermically separated cooling blocks. Specially designed heat exchangers of a are inserted into these blocks. During the process the gas cascades through these heat exchangers. As it is possible to regulate the dew points of the two thermal systems separately, the separation of the moisture transported by the sample gas can be controlled in a narrow band and hence, the washing out of components like SO² is limited to the unavoidable minimum.

Application specific, the TC-Double can be completed with additional equipment such as a sample gas pump, filter, moisture sensor and peristaltic twin pump. The cooling performance is 270 kJ/h. For applications with higher ambient temperatures than 40°C a tuned version performs up to 55°C. The power supply is 230V or 115V AC.
