Practical burner applications in consideration of DIN EN 746-2

Since October 2010, the new version of DIN EN 746-2 Standard, Issue 2011-02, has to be applied. Said version is still indispensable for the constructive design of gas-heated thermoprocessing installations. However, it offers important guidelines and instructions not only for manufacturers but also for the end-users. Amendments thereto were made, for instance, as regards such topics as start-load limitation or outfit of each burner with two class A valves. In the following report, practical applications and examples to meet the more stringent demands are introduced and compared one to another under practical as well as safety-related aspects.
