Description

Boiler combustion chamber inspection and monitoring device {APPARATUS OF A BOILER COMBUSTION CHAMBER CHECKUP}

The present invention relates to a boiler combustion chamber inspection and monitoring device. More specifically, by-product gas (BFG, COG, LDG) generated during the steel mill production process and heavy oil, which is an alternative fuel when the by-product gas is insufficient, are used as the boiler fuel.

The combustion chamber of the boiler that is burning at high temperature should be visually inspected by the monitoring device. The flame monitoring window for visually inspecting the inside of the boiler combustion chamber is fixed so that the angle at which the inspector monitors the flame condition inside the combustion chamber is Boiler combustion chamber that allows the monitoring window to be rotated so that various limitations can be inspected inside the combustion chamber and protects eyes from the high heat and high intensity light emitted during internal combustion chamber inspection and cleans and replaces them. It is about inspection monitoring device.

1 is a schematic diagram showing a general boiler facility, the boiler combustion chamber monitoring device 300 so that the site inspector can visually determine whether the gas fuel supplied to the boiler is being burned in the combustion chamber or injecting heavy oil into the steam. It is installed by drilling a part of the sealed insulation chamber 200.

In order to view the inside of the combustion chamber through the existing combustion chamber monitoring device, when the inspector pulls forward the protective window protective insulation barrier handle bar 9, the barrier membrane 18 inserted into the connecting shaft 10 of the barrier handle bar 9 is lifted. When the combustion chamber 200 is visible and the barrier membrane handle bar 9 is placed, the barrier membrane 18 is lowered to close the boiler combustion chamber monitoring device 300.

However, since the boiler combustion chamber monitoring device 300 is fixed, the angle of viewing when the inspector monitors the flame state inside the combustion chamber 200 is limited, so that only a part of the flame state inside the combustion chamber 200 can be monitored. When liquid fuel is burned, high heat and high intensity light are emitted, making flame monitoring more difficult.

In addition, fuel leakage may occur due to unstable combustion during liquid fuel combustion. As time passes, flame retardants, dust, etc. contaminate the glass, making it difficult to identify the flame state of the combustion chamber.

In particular, when the inspector pulls up the blocking membrane handle bar 9 to check the combustion chamber flame condition, the high temperature and high intensity light is not blocked when the barrier 18 is lifted, thus damaging the eyes of the inspector. In the cleaning and replacement of the combustion chamber, the assembly and dismantling operations are cumbersome, and high heat and softening materials are released, causing dangers to workers.

The present invention has been devised to solve the problems in view of the above-described prior art, and the monitoring window for visually inspecting the inside of the boiler combustion chamber installed at a location that is difficult for workers to access is rotatable, so that the interior of the combustion chamber can be varied. It is an object of the present invention to provide a boiler combustion chamber inspection and monitoring device that can be cleaned and replaced by protecting the eyes from the high heat and high intensity light emitted during the combustion chamber inspection.

The above-described object of the present invention is one side is a flange is formed with a fastener is attached, the middle portion is an annular projection is formed and the other side is a cylindrical body formed with a fastening groove; A first cover seated on the flange and rotatably fastened and the first glass and the first glass end cover separated from each other; A second cover seated on the first cover to be rotatably fastened to the body, and having a second glass and a second glass end cover removable; One side is fixed by the body fixing plate fastened to the annular projection and the other side is achieved by including a corrugated container fixed to the combustion chamber fixing plate attached to the combustion chamber.
