Heat radiation-type oil burner

An oil burner of the heat radiation type comprising:

• a housing;
• a burner body received in said housing;
• a combustion cylinder construction arranged on said housing so as to be in communication with said burner body, said combustion cylinder construction comprising a red-heated combustion cylinder means and a heat-permeable cylinder arranged to surround said cylinder means with a space being defined between said cylinder means and an inner surface of said heat-permeable cylinder;
• an air supply passage defined between said housing and said burner body so as to supply air therethrough to said burner body;
• and,
• air flow means for providing a flow of air along the inner surface of said heat-permeable cylinder so as to prevent clouding of said inner surface by moisture, exhaust gas or the like;
• said air flow means comprising a communicating means for establishing communication between said space of said combustion cylinder construction and said air supply passage so as to supply a part of the air in said air supply passage to said space,
• a first annular plate having an opening formed at a central portion thereof, said first annular plate extending outward from the top of said burner body to said housing and having at least one through-hole formed at a portion thereof positioned above said air supply passage;
• and,
• a second annular plate having an opening formed at the central portion thereof and adapted to support said combustion cylinder thereon, said second annular plate extending inward from the top of said housing to said red-heated cylinder means and having at least one through-hole formed at a portion thereof positioned below said space of said combustion cylinder construction;
• whereby said air supply passage is communicated via said through-holes of said first and second annular plates directly with said space.

An oil burner of the heat radiation type comprising:

• a housing;
• a pot received in said housing;
• a combustion cylinder construction supported on said housing so as to be communicated with said pot, said combustion cylinder construction comprising a red-heated double combustion cylinder having an inner cylindrical member and an outer cylindrical member, and a heat-permeable cylinder arranged to surround said double combustion cylinder with a space being defined between said heat-permeable cylinder and said double combustion cylinder;
• an air supply passage defined between said housing and said pot to supply air therethrough to said pot;
• an annular top plate for said pot outward extending from the top of said pot to said housing and having a plurality of through-holes formed in at least one row;
• an annular top plate for said housing inward extending from the top of said housing to said outer cylindrical member of said combustion cylinder construction and having a plurality of through-holes arranged in at least one row, said annular top plate for said housing supporting said combustion cylinder construction thereon;
• whereby a part of the air in said air supply passage is introduced via said through-holes of said top plates directly into said space of said combustion cylinder construction and upward flows along the inner surface of said heat-permeable cylinder.
