Abstract
PURPOSE: To prevent the generation of thermal stress at an injection pipe for a denitrification agent to a boiler, etc. by a mechanism wherein the injection pipe is suspended from a boiler stand while a feed pipe for cooling water is formed in appropriate length, in a supporting device for the injection pipe.
CONSTITUTION: An injection pipe 7 for a denitrification agent is located in space 8 in a secondary superheater tube group, and atomizes the denitrification agent NH3 from its nozzle. The injection pipe 7 is held by means of spring rods 19 and the upper end portions of the rods 19 by elastic holding means using springs, etc. Pipe length between a metal fitting 15 of a fixing portion at the boiler wall side and a connecting portion 22 between a lower end of the injection pipe 7 and a feed pipe 12 for cooling water is sufficiently made long. Thus, displacement due to the heat of the injection pipe 7 becomes easy, and thermal stress is not generated at the connection portion 22 and the feed pipe 12 for cooling water.
