摘要
Abstract
In order to understand the mixing and flow characteristics of airflow inside the furnace and around the burners under the thermal state operation,taking 660 MW supercritical 4 tangential firing boiler of a power plant in Ningxia as the research object,makes the boiler cold state aerodynamic field test including cold primary air leveling,characteristic test of secondary air inlet damper control,measuring and tracing for the cold aerodynamic field and velocity field inside the furnace. The test result shows that the wind speed of each layer burner nozzle is uniform,flame is full of furnace after air flow formed tangential,the center of the flame is in the centre of the furnace without decline. The test provides the reliable referrence for the thermal state operation and combustion regulating of the units.关键词
