COMBUSTION DEVICE FOR HEATING FURNACE

Document Type and Number:

WIPO Patent Application WO/2012/101814

Kind Code:

A1

Abstract:

The purpose of the present invention is to provide a combustion device for heating a furnace, the combustion device being configured so that the ratio between the amount of primary air flowing through a primary air conduit and the amount of secondary air flowing through a secondary air conduit can be adjusted, the adjustment can be performed using a simple configuration, and an installation space outside the furnace is reduced. A double tube-shaped long burner (B) is provided so as to penetrate through the rear wall (4A) of a wind box (4), the rear wall (4A) being located on the side of the wind box (4) which is separated from a furnace wall (1A). The front end of the burner (B) is disposed within a tube section (T) in such a manner that a secondary air conduit (A2), through which air within the wind box is caused to flow as secondary air, is formed between the outer peripheral surface of the front end of the burner (B) and the inner peripheral surface of the tube section (T). A primary air conduit (A1) for the burner (B) is provided at the front end thereof in such a manner that the air within the wind box is introduced from the rear end and is caused to flow to the front end side. The combustion device is also provided with a burner support means (D) for supporting the burner (B) relative to the rear wall (4A) of the wind box (4) so that the position of the burner (B) can be adjusted in the longitudinal direction thereof.
