Abstract

A flame photometer with constant flow regulation of at least one of the fuel gas components has a buffer container preceded by an on-off valve upstream of a throttle. In conjunction with the volume of the buffer container, the digitally operated on-off valve makes possible both a long-term and a short-term constant supply to the burner.
