Abstract
Through the analysis of the problems in the combustion system of the 1000 MW ultra-supercritical unit boiler of Guoneng(Suizhong)Power Generation Co.,Ltd.,it proposes solutions.It carries out the research and application of the intelligent monitoring and control system for the primary air and pulverized coal of two coal mills in the 1000 MW ultra-supercritical unit.It realizes the in-telligent measurement of the primary air and pulverized coal velocity,mass flow rate,concentration,particle fineness,calorific value and the online adjustment of the primary air and pulverized coal velocity,concentration,and flow rate.Through the optimized design of combustion control strategies and methods by online monitoring technology,it solves the problems of disorderly temperature field in the furnace,uneven heat load,and temperature deviation control on the flue gas side and steam side,thereby improving the safety,flexibility and economy of low-load operation of coal-fired units.关键词
