Flow channel cap plate and combustion chamber assembly including the same

A flow channel cap plate that constitutes a combustion chamber assembly including a combustion chamber configured such that a combustion reaction occurs in an interior thereof and a plurality of insulating pipelines disposed on left and right side surfaces of the combustion chamber and through which heating water flows forwards and rearwards, the flow channel cap plate forming an insulating flow channel, through which the heating water flows from a front surface of the combustion chamber along a periphery of the combustion chamber, by covering the front surface of the combustion chamber, the flow channel cap plate comprising:

• an inlet part including an inlet, through which the heating water is introduced, and an inlet flow channel cap covering the front surface of the combustion chamber;
• and
• an outlet part including an outlet being an exit of the insulating flow channel and from which the heating water is discharged, and an outlet flow channel cap forming an outlet space part by covering the front surface of the combustion chamber,
• wherein an inlet space part is formed by covering the front surface of the combustion chamber with the inlet flow channel cap,
• wherein the inlet is an entrance of the insulating flow channel,
• wherein the plurality of insulating pipelines include a plurality of inlet insulating pipelines,
• wherein the inlet space part is a space that communicates the inlet with the plurality of inlet insulating pipelines such that the heating water is introduced into the inlet, is distributed to the plurality of inlet insulating pipelines, and is discharged, and
• wherein the outlet space part communicates the outlet insulating pipeline with the outlet such that the heating water is introduced from, among the plurality of insulating pipelines, an outlet insulating pipeline, and is discharged through the outlet.

• wherein the inlet flow channel cap is configured to form a parallel flow channel part, in which the heating water is distributed from the inlet to the plurality of inlet insulating pipelines via the inlet space part.

A combustion chamber assembly comprising:

• a combustion chamber configured such that a combustion reaction occurs in an interior space thereof;
• an inlet insulating pipeline and an outlet insulating pipeline disposed on left and right surfaces of the combustion chamber, respectively, such that heating water flows to insulate the combustion chamber;
• and
• a flow channel cap plate including an inlet flow channel cap forming an inlet space part, in which the heating water that is to be delivered to the inlet insulating pipeline flows, by covering a front surface of the combustion chamber,
• wherein the flow channel cap plate contacts the front surface of the combustion chamber such that the inlet space part forms a ring shape when viewed from a front side to a rear side,
• wherein the inlet flow channel cap includes an inlet flow cover in which a inlet is formed and an inlet insulating cover connected to the inlet flow cover, and
• wherein the inlet flow cover is spaced forwards apart from the front surface of the combustion chamber to a front side by a degree that is larger than a degree, by which the inlet insulating cover is spaced apart forwards from the front surface of the combustion chamber to the front side, such that a cross-section of the inlet space part becomes larger as it becomes closer to the front surface of the combustion chamber.
