Abstract

PURPOSE: To realize the reduction of acid cleaning cost and the shortening of process by arranging a heating-steam nozzle apparatus and an acid-liquid injection nozzle apparatus on the pipes or manifolds before and behind a canned-water circulation pump.
CONSTITUTION: As to a complex circulation boiler, water is supplied into a mixing sphere 2 from a fuel economizer 1, and supplied to a water-cooled wall 5 for furnace through a distribution sphere 4 by a conned-water circulation pump 3. A portion of the canned-water which passes through the water-cooled wall 5 for furnace circulates into the mixing sphere 2 through a canned-water circulation valve 15 in low loading, and the rest in sent outside the system through a BT valve 16. In high loading, the water flows outside the system from the fuel economizer 1 through the mixing sphere 2, distribution sphere 4, water-cooled wall 5 for furnace, and the BT valve 16, performing such flowing action as an once-through boiler does. An acid injection nozzle 30 and a steam injection nozzle device 31 are arranged on the pipes and the manifolds before and behind the canned-water circulation pump 3.
