The present invention relates to a flame check window structure for a boiler of a power generation facility including: a check-inducing port (110) having flanges (111) in left and right parts while connecting an inner part to the surface of the boiler (100), forming openings (113) on the upper and lower parts, and elastically inserting and installing an elastic block (114) on the edge of a passage in the front side; a check cover (120) including flanges (121) and openings (123) corresponding to the flanges (111) and the openings (113) of the check-inducing port (110), equipped with a pressing block (124) facing the elastic block (114), and including a main check window (126) seeing through the inside from the outside; upper and lower blocking ports (130) joined to the openings (113, 123) in the upper and lower sides between the check-inducing port (110) and the check cover (120) and closing the inner part; and a safety-check window (140) press-fitted and installed between the elastic block (114) and the pressing block (124) which are interposed between the check-inducing port (110) and the check cover (120). Accordingly, the flame check window structure for a boiler of a power generation facility enables the easy, convenient, and stable replacement and maintenance of the flame check window for the boiler at ease and prevents a leakage of an exhaust gas and foreign materials to the outside by enabling the replacement of the flame check window without opening the boiler in case of damage to the flame check window. |
