| Abstract: | Add a pipe and control valve between condensate water tank and deaerator to reclaim work medium when start-up drain water is qualified.This reformation can overcome disadvantages of once-through boiler start-up system without boiler water circulating pump and restrictions caused by chemical water-production capacity and condenser vacuum.It solves the problem that boiler hot flushing couldn’t be completed one time continuously,the boiler must be stopped to wait for water production and store sufficiently for igniting again.The method can save water resource,shorten boiler cold-start time,it can bring excellent economic benefits for long term operation of the units. |
