BOILER STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2010/064466
Kind Code:
A1
Abstract:
A boiler structure wherein a flow is properly distributed to furnace wall sections by a simple configuration with no movable part in a wide range of furnace heat load ranging from a partial load to a rated load. In the boiler structure, a furnace water-cooled wall (4) comprises a large number of boiler steam generating tubes (3) disposed on the wall surface of a furnace, the water force-fed to the boiler steam generating tubes (3) is heated in the furnace when the water flows in the tubes, and thereby steam is generated. Pressure loss adjusting parts for an internal fluid are installed in the respective outlet communication tubes (10) connecting the outlet sides of the respective water-cooled wall sections formed by dividing the furnace water-cooled wall (4) into a plurality of sections.
