The Concentration of Air and Pulverized Coal Boiler Optimization Methods and Research
The adjustment of the primary and secondary air speed and air quantity in thermal power plant is generally based on the measurement of static meter to show its working condition. It is difficult to adjust the air-coal parameter of each combustor to a reasonable value according to the static value for no certain relationship between the static value and the air speed is available to calculate the air speed and air quantity. The on-line monitoring system of boiler air-powder computer for real-time monitoring is adopted to keep the boiler in a state of balanced and steady combustion. The steady and accurate monitoring system and the automatic input rate of boiler (100%), which could detect the load distribution, pipe blockage, powder interruption and spontaneous combustion accurately, shows considerable value in energy conservation and great practical value in regard to combustion adjustment and reasonable distribution of air and powder.
