Methods for Maintaining Reheat Steam Temperature at a TPP-110 Boiler at Lowered Loads

摘要

Methods for maintaining the temperature of the reheated steam at the TPP-110 twin-furnace boiler of the Novocherkassk GRES during operation at a lowered load are considered. It is shown that the rated temperature of the steam superheat (545℃) can be ensured down to a boiler load of 40% of the nominal one through the redistribution of fuel and feedwater flowrates between the boiler casings and the delivery of flue gas recirculation in casing B.
