MUFFLER INTEGRATED TYPE DENITRATION DEVICE, INTERNAL COMBUSTION ENGINE PROVIDED WITH DENITRATION DEVICE AND POWER GENERATION SYSTEM PROVIDED WITH INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a muffler integrated type denittration device capable of materializing high muffling performance and high denitration efficiency with no enlargement of the device and with smaller space as compared with a case in which a muffler and a denitration device are installed independently.

SOLUTION: An inside of a casing 1 including a flow-in opening 2 and a flow-out opening 4 of gas is divided into at least three chambers 10, 12, 14, communication between adjoining chambers is made by one or two insertion pipes 18 to construct an expansion type muffler, and a dinitration catalyst 16 including passage area equivalent to the insertion pipe is provided instead of the insertion pipe between a pair of adjoining chambers 10, 12 out of a plurality of chambers divided into at least three or more chambers.
