Abstract
The present invention is directed to a flame detection device comprising a flame signal receiver (1), a flame signal passage (11) and a flame signal transmitting mechanism, characterized in that, the flame signal passage (11) passes through a furnace shell (12) into inner of the furnace and comprises an outside-furnace passage portion (11a) and an inside-furnace passage portion (11b); wherein a pressure-resistant optical mechanism (10) is arranged at the outermost end of the outside-furnace passage portion, said pressure-resistant optical mechanism hermetically and transparently separate the flame signal receiver from the flame signal passage; and wherein the inside-furnace passage portion (11b) is provided with a cooling mechanism (19). Such a flame detection device is to be arranged on a furnace shell, and it could not only conduct a flame detection on the furnace under high temperature and high pressure, but also has a selection of the proper flame signal receivers installed for different stages of operation as desired.
