What is atomizing steam in boiler?
Steam atomizing helps in breaking up fuel oil particles into tiny droplets, facilitating easy spread of oil inside the furnace, and maximising combustion. The result is a well spread and intense flame. Without the injection of steam into the burner, the physical state of fuel oil will remain in a liquid form.
What is the purpose of atomizing?
Atomization refers to breaking bonds in some substance to obtain its constituent atoms in gas phase. By extension, it also means separating something into fine particles, for example: process of breaking bulk liquids into small droplets.
What is the purpose of atomizing air in boiler?
Air atomization allows for a better turndown ration, which will allow a burner to run at a lower rate while keeping up with the load, while the pressure atomized burner will have to run at a higher or lower rate and either vent the excess steam or cycle on and off to keep the base load.
What does atomization mean?
transitive verb. 1 : to treat as made up of many discrete units. 2 : to reduce to minute particles or to a fine spray. 3 : divide, fragment an atomized society also : to deprive of meaningful ties to others atomized individuals.
What atomizing means?
1. To reduce to or separate into atoms. 2. To reduce to tiny particles or a fine spray.
What is atomized air?
Air atomizing spray nozzles, also called two-fluid nozzles, produce finely atomized sprays using compressed air or another atomizing gas. Air atomizing nozzles are ideal for a wide range of coating, humidifying, lubricating, gas cooling / conditioning, humidifying and fogging applications.
What causes oil burner puff back?
A puffback occurs when a furnace or boiler does not ignite properly and allows oil or gas vapors to build up within the ignition/combustion chamber. When it does finally ignite, the excess fuel in the chamber causes this puffback scenario.
How many grades of fuel oil are normally considered heating oils?
two grades
There are two grades of heating oil, Number 1 fuel oil and Number 2 stove oil, both of which are volatile and intended for cooking.
How is atomization done in a steam burner?
This atomization is done in three basic ways: 1 By using steam or air under pressure to break the oil into droplets 2 By forcing oil under pressure through a suitable nozzle 3 By tearing an oil film into tiny drops by centrifugal force More
Which is the best dictionary definition of atomizing?
Define atomizing. atomizing synonyms, atomizing pronunciation, atomizing translation, English dictionary definition of atomizing. tr.v. at·om·ized , at·om·iz·ing , at·om·iz·es 1. To reduce to or separate into atoms. 2. To reduce to tiny particles or a fine spray.
How does a steam and air burner work?
The burners consist of a properly formed jet-mixing nozzle to which oil and steam or air is piped. The conveying medium mixes with fine particles of fuel passing through the nozzle, and the mixture is projected into the furnace.
What kind of nozzle is used for atomization?
Hydraulic ( Fig. 10.2 A and B) and twin-fluid nozzles ( Fig. 10.2 C and D) are the most predominantly used atomizers in SFD studies ( Al-Hakim et al., 2006 ). Khwanpruk et al. (2008) achieved atomization of 20% coffee solution using a hydraulic nozzle from a pressurized feed tank at 8 barg.
