PASSAGE STRUCTURE OF COMBUSTION EQUIPMENT AND REGENERATIVE TYPE COMBUSTION EQUIPMENT

摘要

A passage structure (10) of a regenerative type combustion equipment comprises a high temperature gas passage (11,11'), a regenerative box (12,12') and a low temperature gas passage (13,13'). The regenerative box (12,12') comprises a regenerative box body (120) and a regenerative body (121) arranged inside it. One end of the regenerative box body (120) is provided with the low temperature gas passage (13,13') connected with a pipeline, and the other end is provided with the high temperature gas passage (11,11') connected with a combustion furnace body (101). The regenerative type combustion equipment comprises the combustion furnace body (101), and an air passage and a fuel gas passage arranged in pairs. The combustion furnace body is correspondingly provided with a fuel gas nozzle (103) connected with the fuel gas passage and an air nozzle (103') connected with the air passage. The air passage and/or the fuel gas passage adopt(s) the passage structure (10). Therefore, the passage structure has a large cross-section area and a large amount of heat exchange gas.
