Description

Technical Field

[0001] The utility model relates to the technical field of boiler equipment, in particular to boiler combustion monitoring equipment. Background Art

[0002] The purpose of boiler combustion observation is to ensure the safety, stability and efficiency of the combustion process. By observing the combustion state, the combustion parameters can be adjusted in time to prevent slagging, ash blockage, oil scale accumulation and other problems, avoid overheating and corrosion of metal materials, and thus ensure the long-term stable operation of the boiler. In addition, effective combustion observation can also help save energy and reduce emissions, improve thermal efficiency, and reduce pollutant emissions.
