CONTROL FACILITY FOR BURNER SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a control facility for a burner system, which can simply and reliably correct drift of ionization current without exceeding the set limits of combustion values.

SOLUTION: In a second test step, an adjustment device adjusts each actuator toward a supply ratio corresponding to an air excess coefficient above a stoichiometric value of λ=1. Alternatively, the adjustment device reduces the air excess coefficient by a value of ▵λ<-0.06 and changes the air coefficient to a value of λ>1.05. The adjustment device repeats the test after 3,000 driving hours at the latest.
