Abstract
There is provided an improved combination oil and gas nozzle comprising a housing, a forward portion of which includes an enclosed chamber adjacent at least a part of a combustion zone, a gas inlet into said housing leading to a mixing chamber within said housing, an air inlet into said housing leading to said mixing chamber, a series of passages leading from said mixing chamber to a rearward portion of said combustion zone, an oil lance and nozzle extending through the rear portion of said housing and extending essentially centrally into said combustion zone downstream of the outlet of said series of passages, an oil inlet to said essentially annular chamber and an oil passage from said chamber to said oil nozzle. There is further provided a method of utilizing oil and gas in combination in such a nozzle.
Claims19
A combination oil and gas nozzle comprising
- a housing, a forward portion of which includes an enclosed annular chamber adjacent at least a part of a combustion zone,
- a gas inlet into said housing leading to a mixing chamber within said housing,
- an air inlet into said housing leading to said mixing chamber,
- a series of passages leading from said mixing chamber to a rearward portion of said combustion zone,
- an oil lance and nozzle extending through the rear portion of said housing and extending essentially centrally into said combustion zone downstream of the outlet of said series of passages,
- an oil inlet to said essentially annular chamber, and
- an oil passage from said chamber to said oil lance and nozzle.
In a combination oil and gas burning nozzle including a nozzle housing and a combustion zone defined by said housing, a method of utilizing both oil and gas fuels in said nozzle comprising:
- directing said gas through at least one gas inlet passage to a mixing chamber in said housing;
- directing at least a major portion of the air required to support complete combustion in said nozzle through at least one air inlet passage to said mixing chamber whereby to premix said air and gas feeds;
- feeding said mixture into a rearward portion of the combustion zone of said nozzle through an annular series of passages, said passages being sloped or curved to impart a spiralling effect to the mixture in the said combustion zone;
- allowing additional air to be drawn into the combustion zone, through a series of passages in said housing;
- preheating the oil feed to the nozzle by passing said feed through a heat exchange chamber in the nozzle housing adjacent at least a part of said combustion zone;
- and
- directing said preheated oil into said combustion zone through an essentially central oil nozzle extending into said combustion zone downstream of the point of entry of said gaseous feed mixture.
A combination oil and gas nozzle comprising:
- a housing, a forward portion of which includes an enclosed essentially annular chamber encircling a combustion zone, a gas inlet into said housing leading to an annular gas chamber within said housing
- an air inlet into said housing leading to an annular air chamber within said housing,
- a series of sloped passages leading from each of said gas and air chambers, each of said passages from said air chamber meeting a corresponding one of said passages from said gas chamber to form a first series of common air and gas passages leading to a mixing chamber within the nozzle housing, a second series of sloped passages leading from said mixing chamber to form a circular pattern of outlets into the rearward portion of the combustion zone,
- an oil lance and nozzle extending through the rear portion of said housing and extending essentially centrally into said combustion zone downstream of the outlet of said second series of passages,
- an oil inlet to said essentially annular chamber, and
- an oil passage from said chamber to said oil lance and nozzle.
