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.
