Abstract

Abstract:

Large scale wind power integration needs thermal generator regulate output power flexibly; during the reform of boiler for flexibility, the normal operation condition should be kept.To reduce the disturbance to the heat load of the boiler furnace, reduce the expansion of the boiler, and to protect the output power flexibly, the operation parameters of the boiler are studied.The long-distance water soot blower of #1 and #2 furnace in a power plant has larger flow rate and great influence on the boiler parameters during the blowing soot process.By replacing the smaller bore nozzle, the disturbance of the water soot blower to the boiler parameters was controlled.The comparison of operation parameters of the boiler before and after the replacement had proved that it is feasible and safe to change the bore nozzle by smaller diameter nozzle.

Key words: boiler, power regulation, long-distance water soot blower, small bore nozzles, parameters
