SOLID FUEL BURNER AND COMBUSTION DEVICE USING SAME

摘要

A solid fuel burner and a combustion device using the solid fuel burner includes: a throat provided to the outer periphery of a fuel nozzle and injecting combustion gas into a furnace; a duct for delivering the combustion gas to the throat, the duct being provided with an inlet opening into which the gas is introduced from a direction perpendicular to the central axis of the nozzle and having a flow path formed so as to be bent at a right angle in the direction of the central axis of the nozzle; a damper provided in the duct; and a differential pressure detection device for detecting the difference between the pressure of the combustion gas flowing through the upstream portion of the duct and the pressure of the combustion gas flowing through the downstream portion of the duct. The damper is provided near and downstream of the inlet opening of the duct.
