HOT-WATER BOILER

摘要

FIELD: heating systems and hot water supply systems. SUBSTANCE: boiler includes furnace and convective parts formed by walls assembled from tubes interconnected by means of bypass branch pipes fitted tangentially relative to axis of water-wall tubes; these branch pipes have section of slotted form. Ration of sizes of section to diameter of water-wall tubes is: 0.25-0.35-height; 1.3-2.4 - width. EFFECT: reduced hydraulic resistance; increased heat transfer coefficient. 2 dwg
