Piping, header, and tubing arrangement for solar boilers

摘要

A header system for fluid circulation in a boiler includes a header configured to conduct fluid therethrough for circulating fluids in a boiler. A plurality of suction lines are connected in fluid communication with the header. Each suction line is configured 5 and adapted to connect a respective pump in fluid communication with the header. A plurality of downcomers are connected in fluid communication with the header. Each downcomer is configured and adapted to connect the header in fluid communication with a steam drum. The header, suction lines, and downcomers are configured and adapted to draw substantially equal amounts of fluid from each of the downcomers even 10 when flow is uneven among the suction lines. A plurality of cascaded headers can fluidly connect the circulation header to a steam generator. The plurality of cascaded headers is configured and adapted to provide a substantially equal flow to panels of the steam generator. 3021942_1 (GHMatlers) P89048.AU 14-Dec-1l n n n n n n n n 6 0 0 0 0 0 0 0 52a -52b 52c -52d -56a -56b .- 56c 54a 54b 54cA
