SAFE SCAN I visible light flame scanner; experience with improved low load operation and reduction in support fuel. [New patented flame scanner which is not sensitive requires less maintenance and less support fuel to stabilize scanner response]
Flame scanners have been the principle instrument in boiler management safety systems for the past quarter century. Unfortunately, flame scanners have also had a history of high maintenance. In addition flame scanners were inefficient in their ability to see pulverized coal flames without support fuel. By 1982 Combustion Engineering, Inc had accumulated field data from customers operating with the new patented SAFE SCAN I visible light flame scanners. Results from the first year of commercial experience clearly demonstrates its superior sensitivity and reduced periodic maintenance over ultra-violet type flame scanners. This paper summarizes the experiences of two plants with flame scanner performance. A cross section of the industry is represented by offering examples from a utility boiler firing pulverized coal and an industrial boiler firing a combination of pulverized coal and petroleum distillate coke. The significant common denominator realized by both plants is the substantial reduction of support fuel required to stabilize flame scanner response.
