ABSTRACT:
A method and an apparatus for monitoring fuel combustion status in a burner such as a boiler and a gasifier with high accuracy, high reliability and fast response are disclosed. The apparatus comprises a series of fiber optic flame monitors that are installed next to each nozzle inside said burner to determine temperature, flame flash frequency and the burned fuel particle density. In terms of a master controller and a group of on-line controllers, the optimized combustion of the burner is approached by monitoring the combustion status of each nozzle and regulating the discharges of air or oxygen and fuel to each nozzle, in accordance with the comparison of the data detected by flame monitors and optimal data.
