Definitions
- Liquid fuel which is to be utilized in a gas turbine combustion chamber must be atomized at the nozzle portion before proper combustion may take place. Atomizing the fuel consists in breaking down the fuel into kfine particles to form a spray at the nozzle portion.
- Air atomizing consists of striking liquid fuel with va high-temperature, high-pressure jet of air as the liquid fuel leaves the nozzle. This causes the liquid fuel to be broken down into particles and form a cone-shaped spray. Air-atomized nozzles have ecological advantages in that they reduce the amount of smoke present in the combustion process.
- a dual fuel nozzle is one which may run on either gaseous fuel or liquid fuel.
- the criteria which determines which fuel is used may be based on economic considerations or supply considerations.
- high-temperature atomizing air is used in conjunction with the flow of liquid fuel.
- a problem arises when a transfer is made from liquid fuel to gaseous fuel in that a residuum of liquid fuel remains in the liquid fuel or oil passages of the nozzle and is subject to long periods of heat soaking which breaks down the oil into gums, carbon and varnish.
- One source of heat is the high-temperature atomizing air which usually runs adjacent and parallel to the liquid fuel passageway. The deposits of gums, carbon and varnish clog the small orifices in the nozzle and upon retransferring from gaseous to liquid fuels, the liquid fuel pressure becomes excessive and the flow restricted.
- Another object of this invention is to lower the operating temperatures of the nozzle while the nozzle is running on liquid fuels.
- a dual fuel, air-atomized fuel nozzle including a nozzle support ring having concentric flange portions and a center opening.
- a liquid fuel or oil pipe is disposed into the center opening and engages a first flange portion.
- a nozzle cap is disposed about the oil pipe and engages a second flange portion while defining an annular gas plenum.
- a retaining ring is partially disposed over the nozzle cap and engages a third flange portion while defining an annular atomizing air plenum.
- the atomizing air plenum is remotely positioned from the liquid fuel pipe to prevent the atomizing air from heating the liquid fuel or liquid fuel residuum.
- the gas plenum provides additional nozzle cooling when the nozzle is operating on gaseous fuel and further acts to prevent thermal breakdown of residuum liquid fuel.
- FIG. l is an elevation view, partially in cross section. of a dual fuel, air-atomized nozzle with a swirler cap having the present invention applied thereto.
- the swirler cap 3l has external threads which are secured into a second threaded flange portion 35 on the nozzle support ring 15.
- the swirler cap has a plurality of swirler blades 37 circumferentially arranged at the forward end of the swirler cap and having gas distribution holes 38 positioned between selected blades.
- a circumferential mounting ring 39 surrounds the swirler blades and positions a combustion chamber casing 40 and liner 4l.
- An annular atomizing air plenum 7l is defined within the retaining ring 59, the nozzle cap 3l and the nozzle support ring 15.
- the plenum 7l is supplied by means of a plurality (only one shown) of circumferentially arranged inlet pipes 75 which are connected to an outside supply pipe.
- Atomizing air is delivered to the nozzle face through a plurality of air passages 79 (only one shown) into a distribution ring 80.
- the distribution ring 80 is an annulus adjacent the nozzle casing which feeds atomizing air to circumferentially arranged slots or openings 8l in the face of the casing 25 to distribute atomizing air to the fuel emanating from the fuel nozzle.
- FIG. 2 a second embodiment of a dual fuel atomized fuel nozzle lll is shown including a nozzle support ring 115.
- a centrally mounted oil supply pipe 119 is connected at one end to an oil supply source and terminates at the other end in an oil nozzle 121.
- the oil pipe is formed within a casing 125 having an exterior threaded portion. The threaded portion is secured within a first threaded flange portion 129 on the nozzle support ring.
- a shrouded nozzle cap 131 is positioned about the front end of the oil pipe casing 125 and includes an exterior threaded portion which is secured within a second threaded flange portion 13S of the nozzle support ring.
- the outer portions of the shrouded nozzle cap contact a combustion chamber casing 140 and liner 141.
- the nozzle support ring, the oil pipe casing and the shrouded nozzle cap define an annular gas plenum 145.
- a plurality (only one shown) of circumferentially arranged inlet pipes 149 feed gaseous fuel from a supply pipe to the plenum which is distributed to the shrouded nozzle cap face through gas passages 151 and outlet holes 153 in the face of the nozzle cap. Both the gas passages and the outlet holes are circumferentially arranged about the nozzle cap.
- the nozzle may operate on liquid fuels such as oil or it may operate on gaseous fuel.
- hot atomizing air is sent through the air passages so that oil flowing through the oil nozzle is atomized.
- the atomizing air is at a temperature of about 350F.
- a further benefit of the transportation of the gaseous and air atomizing pipes is that the nozzle itself will run cooler about l50F when operating on liquid fuel.
- liquid fuel conduit partially disposed within said center opening and engaging a first concentric flange
- At least one gas supply pipe interconnecting said gas plenum with a gas supply through said nozzle support ring; and, gas passageways through said nozzle cap interconnecting the gas plenum with said combusion chamber; and,
- nozzle cap is formed with a plurality of concentrically arrayed outlet holes communicating with the combustion chamber and through the face of the nozzle cap; the gas passageways interconnecting the gas plenum with said circumferentially arrayed holes.
- the nozzle as recited in claim l further including a plurality of atomizing air inlet pipes passing through the nozzle support ring and interconnecting the atomizing air plenum with an atomizing air supply.
