BOILER Russian patent published in 1995 - IPC

FIELD: power engineering. SUBSTANCE: dispensing pipes 4 of cooling component manifold are mounted in such position that form square grid in projection on cross section of horizontal gas duct. Projections of axes 6 of holes 5 of pipes 4 on this plane are so located in each cell of grid that form conventional square. Sides of square of each cell of grid are equal to 2.45 to 2.55 of side of above-mentioned conventional square. Effective mixing of combustion products of boiler with cooling component is ensured in transverse jets, thus smoothing the parameters of flow of combustion products before convective shaft and enhancing economical efficiency of boiler. EFFECT: enhanced economical efficiency through enhanced mixing of combustion products with cooling component in transient conditions. 3 dwg
