PURPOSE:To drain condensed water, as well as to silence noise, by stepwisely juxtaposing a plurality of silencer chambers in the vertical direction, and by connecting these silencer chambers in series by water drain and gas exhaust pipes in combination, in the titled pulsation burner. CONSTITUTION:Combustion gas, exhausted from a pulsation burner, is fed into the first can body 11 passing through a gas exhaust pipe 14, and introduced into the second can body 12 passing through a gas exhaust pipe 15 combined with a drain pipe, further, into the third can body 13 passing through a gas exhaust pipe 16 combined with a drain pipe, and finally, is discharged from a discharge port 17 into the open air. With such an arrangement, noise generated by pulsation of combustion gas can be silenced by stages, while condensed water produced during combustion is discharged, passing through gas exhaust pipes 15, 16, and 17, combined with drain pipes, respectively. The silencer device is composed compactly, because the gas exhaust pipes combined with drain pipes are connected to each other, being inserted into each silencer chamber. |
