Problems solved by technology

[0016] This solution has several disadvantages, since a "fact finder" operator is always required and (if possible) the operator needs to go to the power plant site and when the burner has been properly cooled (the temperature inside the burner cannot be greater than 40° C, that is, usually after cooling down for 1.5-2 days) into the burner
[0017] Therefore, such procedures do not permit rapid restart of equipment after unscheduled downtime

Embodiment Construction

[0033] exist figure 1 Among them, reference numeral 1 denotes a gas turbine assembly for electric energy production, which includes a compressor 3, a combustor 4, a gas turbine 5, and a generator 7 that converts mechanical power supplied by the turbine 5 into electric power to be supplied to The electricity grid 8 is connected to the generator 7 via a switch 9 .

[0034] A variant not shown provides the assembly 1 as a mixed cycle type and comprising, in addition to the gas turbine 5 and the generator 7 , a steam turbine.

[0035] The gas turbine 5 extends along a longitudinal axis A and is provided with a shaft 10 (also extending along the axis A) to which the compressor 3 and the generator 7 are also connected.

[0036] The gas turbine 5 comprises an expansion channel 12 in which the hot gaseous working fluid from the combustor 4 flows in a direction D.

[0037] The expansion channel 12 has a section (or section) that increases radially in a direction D along the axis A. ...

Abstract

The present invention relates to a device and method for inspecting a combustor. The device for inspecting the combustor comprises a sensing probe (22); and an arm (23) having one first end (24) coupled to the sensing probe (22) and one second end (25) coupled to a base (26). The arm (23) comprises a plurality of modules (27) coupled to one another, each module (27) is coupled to the adjacent module (27) with a respective rotational joint (28), and each rotational joint (28) is independently controlled.

Description

[0001] Cross References to Related Applications [0002] This patent application claims priority to European Patent Application No. 19425102.1 filed on December 31, 2019, the entire disclosure of which is incorporated herein by reference. technical field [0003] The invention relates to a device and a method for inspecting a burner. In particular, the apparatus and method of the present invention are useful for inspecting combustors of industrial gas turbine assemblies used to generate electricity. Background technique [0004] As is well known, industrial gas turbine components for power generation include compressors, combustors and turbines. [0005] Specifically, the compressor includes an inlet fed with air and a plurality of rotating blades that compress the passing air. Compressed air leaving the compressor flows into the plenum, the enclosed volume delimited by the outer casing, and from there into the combustor. Within the combustor and by means of a plurality o...
