Boiler Temperature Field Testing Service
Project Overview
The flame temperature field testing and combustion adjustment service project for the boiler burner of China Resources Power (Changshu) Co., Ltd. has been completed. This project optimizes the combustion process and improves combustion efficiency through precise testing and in-depth analysis of the flame temperature field of the boiler pulverized coal burner.

Testing Equipment
The testing equipment used for this service is the Tempvision1100 portable dual-color spectral temperature testing device developed and produced by Safefire specifically for flame temperature field testing of coal-fired boilers.
This device uses dual-color spectral method for temperature testing, featuring high accuracy and strong resistance to fly ash. Additionally, due to its unique optical collection structure, the device can collect flame temperature signals through the on-site flame detection pipe, making it easy to operate.
03
Testing Method
The flame temperature field testing of the boiler burner used the Tempvision1100 temperature field probe for precise testing. The specific operation involves first removing the flame detector and its internal pipe from each burner, then inserting the temperature probe into the external pipe of the flame detector for temperature data collection.
04
Testing Scope
The testing scope for this test includes all 32 burners, with each burner's testing duration being 3 minutes. The testing is divided into three operating conditions, specified by the client based on the operating conditions during the testing period. Testing begins when the designated load is reached and stops when the load exceeds ±10MW of the designated load.
05
Testing Results
This test found that among the 32 burners, there were significant temperature deviations between layers; different degrees of over-burning, insufficient combustion, and instability issues existed among the burners on the same layer.
06
Combustion Adjustment
Based on the test data results, engineers made targeted adjustments to the air supply of the problematic burners. After combustion adjustment, the combustion temperatures among the burners stabilized, temperature deviations decreased, nitrogen oxide emissions were reduced, and the overall combustion efficiency of the boiler improved.
Two
Project Results
Through three professional service tests and analyses, the distribution of the burner flame temperature field for each unit under different load conditions was clarified, accurately identifying burners with temperature deviations and combustion stability issues. This provides detailed data support and scientific basis for the maintenance and operation of the units, helping to improve combustion efficiency and ensure the safety and economy of boiler operation.
