Abstract:The construction of two 660MW coal fired turbine generator boilers in Huadian Xinxiang Power Generation Company Limited frequently coke and coke out.In order to ensure unit safety and economic operation,decoking agent was added in boilers.The best solution was selected through tests on the coal,as well as the position,amount and composition of decoking agent. After the implementation of the program,the boiler coking was effectively reduced and the stability of the boiler was improved.
