The body casing is formed with a body inlet port on a body bottom, and a body outlet port is formed in each body side.

The body casing is formed with a body inlet port on a body bottom, and a body outlet port is formed in each body side.

Further, outlet ports are formed.

In each of the body outlet port, a joint is protrudingly provided with a body-side duct connecting portion that connects a duct thereto.

The plenum chamber has a shaped exit that causes a predetermined waterfall effect.

Liquid fuel that flows downwardly to a lower extremity (48) of the mixing chamber is removed through a liquid outlet (56).

A connecting sleeve directs the combined output into a cabinet containing components to be cooled.

A sound-muffling soot collector has a main case (1) filled with filter liquor (2), an inlet (11) and an outlet (12) mounted on the main case (1).

The cabinet-side connectors are electrically connected to a driver electronics board (98) within the cabinet and carry all input/output functions of the driver electronics board.

The system comprises first pumping means having an inlet selectively connectable to an outlet from the enclosure.

The common sound output chamber is in acoustic communication with each plenum through respective flow passageways and has a sound output opening for passage of the combined sound output.

The chamber has a pressure-reducing pump, an air outlet connected to the pressure-reducing pump, and a natural air inlet provided at a position opposite the air outlet.

A heat exchanger includes a casing (8), an inlet (9) and an outlet (5) for heated fluid.

The steam extraction outlets are arranged either singly at or near the uppermost point of the casing or in pairs to either side of the uppermost point of the casing.

A scrubber canister is coupled to the mouthpiece and receives the output of the mouthpiece through the second one-way valve.
