The atomizing type of burner prepares the oil for burning by breaking it up into a fog-like vapor.

Oil furnace operations have not changed very much. On a call for heat from the thermostat, the burner motor will start. Oil is now pumped to the nozzle, and the ignition transformer is energized. The nozzle is designed to spray the oil into the fire tube as a fine mist. The ignition transformer is designed to create an electrical arc across the electrodes.

In the past, it seems that burners were almost an afterthought in port design-furnace designers looked only at how to match burner and combustion air velocities. However it was during this decade that operators realized that they could reduce NO_x rates significantly by controlling the mixing rates of fuel and air. By delaying the mixing of fuel and air, operators then found that flame luminosity could be enhanced-thereby increasing efficiencies and reducing pollution. The delayed mixing would lead to increased cracking of the gas-- which increased the radiative effect of the flames.  3, fiche 19, Anglais, - delayed%20mixing

Atomization or spraying is divided into three types, namely, high-pressure atomization, low-pressure atomization, and centrifugal atomization. With high-pressure atomization used by high-pressure gun-type burners, the oil pressure is built up to 100 psi by a pump and delivered through an oil line to a specially designed nozzle from which it sprays out into the combustion chamber in a vaporous cloud of tiny globules or droplets.

Domestic burners... employ either one of two methods to prepare the fuel oil for combustion. These are atomization(spraying) and vaporization(heating). Atomization or spraying is divided into three types, namely, high-pressure atomization, low-pressure atomization, and centrifugal atomization... Low-pressure air atomization is also a well-known method that has been used successfully by domestic oil burners to prepare the oil for combustion. This method is peculiar to low-pressure burners. These burners achieve their objective by delivering oil and air to the nozzle at a pressure of from 1 to 15 psi, depending upon the make of the burner. With these burners the oil and air come in contact with each other before leaving the burner. The air is used to atomize the oil into fine particles, and it leaves the nozzle opening in the form of a mist.  1, fiche 26, Anglais, - low%2Dpressure%20air%20atomization

Horizontal Rotary Cup Oil Burners. This type of burner atomizes the oil by spinning it in a thin film from a horizontal rotating cup and injecting high velocity primary air into the oil film through an annular nozzle which surrounds the rim of the atomizing cup. This atomizing cup and frequently the primary air fan are mounted on a horizontal main shaft which is motor driven and rotates at constant speed, 58 to 100 r/s depending on the size and make of burner. The oil is fed to the atomizing cup at controlled rates from an oil pump which is usually driven from the main shaft through a worm and gear.  2, fiche 27, Anglais, - horizontal%20rotating%20cup

Return Flow Mechanical Atomizing Oil Burners.... This is a register-type burner similar to the mechanical atomizing burners. Wide range is accomplished by use of a return-flow nozzle which has a swirl chamber just ahead of the orifice or sprayer plate. Good atomization is attained by maintaining a high rate of oil flow and high pressure drop through the swirl chamber. The excess oil above the load demand is returned from the swirl chamber to the oil storage tank or to the oil pump suction. Control of burning rate is accomplished by varying the oil pressure in both the oil inlet and the oil return lines.  1, fiche 28, Anglais, - swirl%20chamber

The high pressure atomizing type gun... burner supplies oil to the atomizing nozzle at 689 to 2067 kPa. A blower is used to supply the air for combustion, and a damper or other adjustable means regulates the air supply at the burner. Ignition is usually established by a high voltage electric spark which may be intermittent, sometimes called constant ignition(on when the burner motor is on) or interrupted(on only to start combustion). Typically these burners fire into a combustion chamber in which negative draft is maintained.  1, fiche 30, Anglais, - constant%20ignition

The low pressure air atomizing burner uses comparatively large volumes of air at low pressure(5 psi or less). Air from the lower passes through the burner body and is discharged through annular slots between the body and the nozzle tip, where it meets the film of oil at an angle as it issues from the tip. The impact of the air stream upon the oil film produces a fine mist which is projected into the combustion space. These burners may be fired with light or heavy oil. They are most often used to fire industrial heating and processing furnaces....  1, fiche 31, Anglais, - low%20pressure%20air%20atomizing%20burner
