Experimental Study on Deep Peak Shaving of Coal-fired Boilers on Oxygen Rich Combustion
With the continuous increase in the proportion of renewable energy consumption,the number of coal-fired units entering deep peak shaving and peak shaving time will further increase,and the problem of low boiler efficiency under ultra-low load will become more prominent.This article studies the deep peak shaving operation and performance of coal-fired boilers based on oxygen rich combustion,obtains the main operating parameters of the boiler under low load,and comprehensively analyzes the problem of low boiler efficiency under low load and takes reasonable measures.The experimental results show that the deep peak load regulation of the oxygen rich combustion boiler can reach 30%of the rated load,and the main operating parameters can meet the safety and environmental protection requirements of the boiler.Through maintenance,renovation,and operation adjustment,the boiler efficiency under ultra-low load has been improved by 2.25%.The research results provide ideas for improving the economic efficiency of deep peak shaving boilers.
