A Micro-Computer-Based Fuel Optimization System Utilizing In-Situ Measurement of Carbon Monoxide
Abstract
A microcomputer-based control system utilizing a distributed intelligence architecture has been developed to control combustion in hydrocarbon fuel-fired boilers and heaters to significantly reduce fuel usage. The system incorporates a unique flue gas analyzer that mounts directly in the flue or stack to continuously measure carbon monoxide, unburned hydrocarbons, opacity and temperature. The control console interfaces directly with the boiler's existing analog control system to provide precise air fuel ratio control based on carbon monoxide measurements. Significant decreases in excess air result in reduced fuel usage while meeting steam demand. Actual performance on industrial boilers shows increases in efficiency of from 1% to 3% with substantial fuel savings.
