Success with the Valmet Acoustic Pyrometer at the Xinyuan Power Plant
Oct 9, 2020
The continuous furnace temperature measurement during the full load is a difficult problem. On the 700MW supercritical boiler furnace at the Xinyuan power plant in China this has been solved with the installation of a Valmet acoustic temperature measurement system.
Summary
Location
Xinyuan, China
Customer challenge
Continuous measurement of the furnace temperatures during the full load.
The system provides a large amount of data on furnace combustion conditions and flue gas temperature distribution.
Results
Reduced superheater coke formation
Determination of the proper flame height
Reduction of possible damage caused by flame deflection

2D Temperature field distribution. The system utilizes 2 acoustic generators (ASG) and 8 acoustic receivers (ASR) to determine the temperature distribution in 16 zones of the furnace outlet. The 16 zone temperature information and a 2D temperature field distribution are presented on a control room screen for operating personnel to make the correct adjustments and optimize combustion conditions.
