METHOD AND APPARATUS FOR MONITORING COMBUSTION PROPERTIES IN AN INTERIOR OF A BOILER

摘要

The present invention between the tube adjacent on relates to a process for the combustion characteristic monitored in the interior of the type having a wall comprising a plurality of parallel steam tubes are separated by a metal film boiler, the first and second through additional boiler opposite side of being formed on the metal film, through the pitch-optical device including a pitch relay lens pitch with a condenser lens that is positioned outside the interior of the boiler the light beam is projected, the pitch relay lens is a beam into the boiler through the perforations projection, and wherein the light beam is received by the same catch optics substantially with God pitch optics positioned outside of the boiler, said condenser, and the intensity of the received light beam is determined and the pitch condenser lens and the catch condenser lens at least one is oriented so as to maximize the intensity of the converging beam of light and a light receiving. ;
