Testing the burners of exhaust-air purification systems under live conditions
Goldkronach, December 2015 – Dürr has recently been testing the burners fitted to its Ecopure TAR exhaust-air purification systems on a multi-function test stand. One of the advantages is that commissioning at the customer’s site can now be executed faster.
Before replacing a defective or outdated burner, staff of Dürr’s Clean Technology Systems Division perform an examination of the exhaust-air purification system. The conditions prevailing at the customer’s site are then simulated on the test stand, allowing the new burner to be adapted to the applicable pressure levels.
Dürr is using the test stand at its site in Goldkronach (near Bayreuth, Germany) for all TARCOM burners with gas, oil or combined gas/oil operations – and also as a basis for developing further enhancements for these models. “We are working on optimizing our products and have the ideal facilities at this site to do this,” explains Werner Zondler, Sales Manager for exhaust-air purification systems.
Dürr assembles the burners almost completely on its own in Goldkronach, where it holds large inventories of spare parts, which are now available more quickly than before the commencement of internally sourced production.
The test stand is now also being used for internal training purposes. Dürr service staff share their experience in the use of the burner with specialists from the Clean Technology Systems and are briefed on the latest developments. These “Burner Days” are held regularly in Goldkronach. In this way, Dürr service staff are able to offer customers expert advice and answers.
Dürr testing further product components
However, the multi-function test stand is not only being used for TARCOM burners but also for other key product components developed by Dürr’s Clean Technology Systems Division. Hot gas valves of the type used in the Ecopure RTO regenerative thermal exhaust-air purification systems are also tested here. As well as this, it is possible to monitor the performance data of ORC (Organic Rankine Cycle) systems. Dürr offers customer trainings at this site for this technology, which uses waste heat to produce electricity.
The test stand is operated at LTB (Luft- und Thermotechnik Bayreuth) in Goldkronach, which has been part of the Dürr Group’s Clean Technology Systems Division since July 2013.
