Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for efficiently packing accessory parts of an intake / exhaust type combustor.

[0002]

2. Description of the Related Art An intake / exhaust type combustor of this kind requires an intake / exhaust top in which an intake part for outdoor air and an exhaust part for combustion air are integrally formed, unlike a general open type combustor. ,
It is also necessary to have parts that attach and fix the intake and exhaust tops. Then, if this kind of accessory is lost, the combustor cannot be used. Therefore, in the past, the combustor was stored in a dedicated cardboard box, and the cushioning material was inserted together so as to withstand the shock during movement.

The intake / exhaust top, which is the largest of the attached parts, is attached by fixing it to the back plate of the frame with a tightening band or the like in a state where a part is assembled to the combustor. A proposal has also been made to make the box for storing the parts smaller.

[0004]

In most cases, the accessory parts are stored in a cardboard box, and this cardboard box is packed together with the combustor. However, there is a problem that the packing size becomes large, and a plurality of cardboard boxes are used. Since the accessory parts are put in a dedicated cardboard box, a cushion material was needed between the parts. In addition, it is difficult to understand even if the parts to be placed in the dedicated cardboard box for the accessory parts are missing, this point is not only when shipping the factory, but forgetting to put the accessory parts in the dedicated cardboard box when storing and storing the combustor. , May be lost.

Also, in order to downsize the dedicated cardboard box, the main body of the intake / exhaust top, which is a large accessory, is fixed to the back plate of the frame by using parts such as tightening bands that are unnecessary when used. With this structure, although the packing size of the combustor can be made somewhat smaller, there is a risk that the fixed parts removed during installation when the combustor is stored and stored will be lost and cannot be properly fixed.

In any of the structures, the cost for packing the dedicated parts is considerably increased, such as using a dedicated cardboard box, putting a cushioning material, and putting paper on which a list of the dedicated parts is written. And was added to the price of the combustor.
