Kind Code:
A1
Abstract:
[PROBLEMS] To attain a reduction of weld working load at the fabrication of boiler
water wall panel and attain a reduction of maintenance load and enhancement of
rate of operation for a furnace housing with built-in boiler water wall panel.
[MEANS FOR SOLVING PROBLEMS] Boiler water wall panel (80) comprises panel body
(70) with water channel having constituent units of metallic seamless finned
single tubes (60) integrally fabricated by hot extrusion technique, etc., these
metallic seamless finned single tubes at the distal end of fin portion (62) welded
and connected to each other as seam (71) and, provided on at least one surface side
of the panel body (70), internal central region weld coating (82) and periphery
weld coating (81) of anticorrosion alloy. The finned tube body (60) has tube
body part (61) for cooling water channel and, extending on both sides thereof
in the direction of tube body axial line, a pair of fin portions (62) wherein intervening
