Kerosene burners

The technology of kerosene burners is quite mature. The most popular kerosene heater is the perforated sleeve vaporizing burner or range burner (Figure 1). It consists of a pressed steel base with concentric, interconnected grooves and perforated metal sleeves, between which combustion takes place. Kerosene is maintained at a depth of about 1/4 inch in the grooves. As the base heats up, oil vaporizes from the surface, and the flame lights from asbestos wicks. Combustion air is induced by natural draft. The flame is blue, and the burner is essentially silent, odorless, and smokeless. 

Flame height is lessened in wick-fed kerosene burners kerosene consumption is decreased.

The exacting Hst of specification requirements for aviation gas turbine fuels and the constraints imposed by deUvering clean fuel safely from refinery to aircraft are the factors that affect the economics. Compared with other distillates such as diesel and burner fuels, kerosene jet fuels are narrow-cut specialized products, and usually command a premium price over other distillates. The prices charged for jet fuels tend to escalate with the basic price of cmde, a factor which seriously underrnined airline profits during the Persian Gulf war as cmde prices increased sharply. 

Fuel specifications from different sources may differ in test limits on sulfur, density, etc., but the same general categories are recognized worldwide kerosene-type vaporizing fuel, distillate (or gas ou ) for atomizing burners, and more viscous blends and residuals for commerce and heavy industry. Typical specifications are as follows. 

This principle is confined to domestic applications where kerosene or premium gas oil is concerned. The simplest type uses a number of concentrically arranged wicks which promote vaporization of kerosene into an air/vapor mixing zone enclosed within a perforated dmm arrangement. Normally, these burners obtain their air by natural draft. 

A variety of formulations exist for cleaning organics from burners and other fireside areas. Soot, oil, and grease removers are widely available the formulations are often very specific and can be produced in both aqueous and nonaqueous solvent bases. Nonaqueous solvents commonly include petroleum spirit, naphtha, or odorless kerosene. 

A two-color pyrometer has been used along with the phase-Doppler anemometer to simultaneously measure the local velocity and size of kerosene droplets and the temperature of burning soot mantle in a swirl burner.[648] The measurements were conducted within the flame brush that develops in the shear layer of a swirl-stabilized, gas-supported kerosene flame with a swirl number of about 0.19 and potential heat releases of 10.6 and 15.5 kW, respectively. The results showed that the maximum burning fraction of the droplets occurs adjacent to the region denoted as gas flame but the value ranges from 20 5 to 40 5% depending on the axial station, and decreases sharply across the shear layer. The flame mantle temperature was found to be independent of droplet diameter, which agrees with previous results in the literature.

Fuels used to power marine, truck, automotive, railroad, and industrial diesel engines fall into the general category of diesel fuel. Heating oil, burner fuel, kerosene, and heavier residual fuels fall primarily into the category of fuel oil.

Jet fuel, burner kerosene, heating oil, and heavy marine fuel oils do not typically contain detergents. The widespread need for detergents to improve fuel performance in these applications has not yet developed. Although in some small markets, combustion catalysts and burner nozzle antifoulants are utilized. 

If the viscosity of kerosene is too high, it will not readily travel up the wick of burners and kerosene lamps. Fuel consumption will be low and the flame will not be bright.
