Document Type and Number:
Japanese Patent JP2015197263
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a pulverized-coal burner in which abrasion wear is restricted, its structure is simplified and its manufacturing is easy.SOLUTION: This invention has a configuration in which it comprises a burner nozzle 10 including an injection port 11 for injecting mixed fluid F of fine coal and combustion air and a transferring flow passage 12 for the mixed fluid F reaching the injection port 11; a mixed fluid flowing-in pipe 20 connected to the side part of the burner nozzle 10 for flowing the mixed fluid F into the transferring flow passage 12 and a fine coal concentration distribution adjustment member 30 arranged in the transferring flow passage 12 at a downstream side than the connected position of the mixed fluid flowing-in pipe 20 so as to cause a flow passage area S2 opposite to a flow passage area S1 to which the mixed fluid flowing-in pipe 20 is connected to be relatively small.
