摘要

Furnace system (11) comprises many burner nozzles (2.1) for combustion of a mixture flow and a lambda sensor (12.1) for the analysis of a smoke gas composition, where the lambda sensor is arranged on at least one of the burner nozzle. Independent claims are also included for: (1) the burner nozzle comprising a nozzle head (13), over which the mixture flow is introduced into the burner nozzle, which exhibits an opening, suitable for smoke gas extraction; (2) the nozzle head for the burner nozzle comprising the opening suitable for smoke gas extraction; and (3) measuring a lambda value in at least one burner nozzle of the furnace system, comprising removing of smoke gas from inside the burner nozzle at an opening of the burner nozzle, leading the removed smoke gas to the lambda sensor via a cable, which is associated with at least one burner nozzle, and analyzing the smoke gas composition of the at least one burner nozzle with the lambda sensor of at least one burner nozzle.
