Heat exchange chamber for coal forming

Abstract

The invention relates to a heat exchange chamber for coal forming. A heat exchange pipeline penetrates through the interior of the heat exchange chamber and the heat exchange chamber communicates with a combustion chamber; the heat exchange pipeline is used for transporting gas into the combustion chamber; a heat exchange passage is arranged outside the heat exchange pipeline; the heat exchange passage is used for laying the heat exchange pipeline; the heat exchange pipeline comprises a plurality of circulation sections and a plurality of connection sections; and the connection sections are correspondingly connected between the air outlets and the air inlets of every two adjacent circulation sections to form a continuous passage. According to the heat exchange chamber for coal forming, the situation that the heat exchange pipeline is broken when heated to expand can be reduced, energy can be effectively stored and transferred, the heat energy recovery efficiency is improved, the structure is compact and symmetrical, only one circulation section needs to be replaced when the heat exchange pipeline is broken, and the heat exchange chamber for coal forming is suitable for wide popularization and use.

Description

Technical field[0001]The present invention relates to the field of coking techniques, and more particularly to a heat exchange chamber for coal formation.Background technique[0002]At present, the two-segment coke oven, two-segment coke oven, which are set up from top to bottom, have a turntable, ramp, and combustion chamber, in practical applications, the heat exchange chamber is provided with a heat transfer tube, normal temperature air. The intake port above the heat transfer pipe enters the heat transfer pipe. After the heat transfer pipe, the air outside the heat transfer pipe enters the end wall, thereby enabling the air into the combustion chamber, while the high temperature combustion exhaust gas in the combustion chamber passes The fireway enters the heat exchange chamber, and heatsum heat in the heat exchange chamber with the normal temperature air in the heat exchange tube, thereby reducing the discharge temperature of the combustion exhaust gas, and preheating the normal ...

AI Technical Summary

Problems solved by technology

[0003] However, in the prior art, the material used to make the heat exchange tubes is relatively brittle, which causes the heat exchange tubes to easily crack when heated and expands, which makes the service life of the heat exchange tubes shorter and affects the stability of the heat exchange tubes
