Abstract
Abstract In a burner assembly connected with a combustion chamber at a fuel inlet of said combustion chamber, the improvement of which comprising a fuel duct which is connected at its one end to said fuel inlet and contains therein a fuel injection nozzle, ignition rod and air-fuel mixture diffuser, a blower means which has an outlet for blowing an air through said outlet of the blower means and said fuel duct into said combustion chamber, and a conduit member coupled to said inlet of the blower means, whereby pneumatic oscillation plane progressive waves are converted into plane stationary waves to thereby reduce progressive energy of said pneumatic oscillation plane progressive waves.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
152 words
A burner assembly connected with a combustion chamber at a fuel inlet of said combustion chamber comprising: a fuel duct having a first end connected to said fuel inlet and a second end spaced from said first end, said fuel duct containing therein a fuel injection nozzle, ignition rod and air-fuel mixture diffuser; a blower means having an inlet for receiving air and an outlet for blowing received air into said second end of said fuel duct, the air blown into said fuel duct passing through said fuel duct into said combustion chamber; and a generally cylindrical conduit member coupled to said inlet of the blower means and extending axially away from said inlet, said generally cylindrical conduit member having a length of about 0.8m to about 2.7m, whereby pneumatic oscillation plane progressive waves are converted into plane stationary waves to thereby reduce progressive energy of said pneumatic oscillation plane progressive waves.
Claim 2
Dependent Claim
152 words
A burner assembly connected with a combustion chamber at a fuel inlet of said combustion chamber comprising: a fuel duct having a first end connected to said fuel inlet and a second end spaced from said first end, said fuel duct containing therein a fuel injection nozzle, ignition rod and air-fuel mixture diffuser; a blower means having an inlet for receiving air and an outlet for blowing received air into said second end of said fuel duct, the air blown into said fuel duct passing through said fuel duct into said combustion chamber; and a generally cylindrical conduit member coupled to said inlet of the blower means and extending axially away from said inlet, said generally cylindrical conduit member having a length of about 0.8m to about 2.7m, whereby pneumatic oscillation plane progressive waves are converted into plane stationary waves to thereby reduce progressive energy of said pneumatic oscillation plane progressive waves.
Claim 3
Dependent Claim
16 words
A burner assembly as claimed in claim 1 wherein said conduit member has an adjustable length.
Claim 4
Dependent Claim
24 words
A burner assembly as claimed in claim 1, wherein said burner assembly further comprises an additional tubular member telescopically connected with said conduit member.
Claim 5
Dependent Claim
22 words
A burner assembly as claimed in claim 1 wherein a sound absorption material is disposed on the interior of said conduit member.
Claim 6
Dependent Claim
152 words
A burner assembly connected with a combustion chamber at a fuel inlet of said combustion chamber comprising: a fuel duct having a first end connected to said fuel inlet and a second end spaced from said first end, said fuel duct containing therein a fuel injection nozzle, ignition rod and air-fuel mixture diffuser; a blower means having an inlet for receiving air and an outlet for blowing received air into said second end of said fuel duct, the air blown into said fuel duct passing through said fuel duct into said combustion chamber; and an adjustable conduit member coupled to said inlet of the blower means and extending axially away from said inlet, said conduit member having a bellows-like construction and a length variable between 0.8m and 2.7m, whereby pneumatic oscillation plane progressive waves are converted into plane stationary waves to thereby reduce progressive energy of said pneumatic oscillation plane progressive waves.
Claim 7
Dependent Claim
152 words
A burner assembly connected with a combustion chamber at a fuel inlet of said combustion chamber comprising: a fuel duct having a first end connected to said fuel inlet and a second end spaced from said first end, said fuel duct containing therein a fuel injection nozzle, ignition rod and air-fuel mixture diffuser; a blower means having an inlet for receiving air and an outlet for blowing received air into said second end of said fuel duct, the air blown into said fuel duct passing through said fuel duct into said combustion chamber; and an adjustable conduit member coupled to said inlet of the blower means and extending axially away from said inlet, said conduit member having a bellows-like construction and a length variable between 0.8m and 2.7m, whereby pneumatic oscillation plane progressive waves are converted into plane stationary waves to thereby reduce progressive energy of said pneumatic oscillation plane progressive waves.
