Related Terms

ATOMIZER

part of an oil gun which breaks up the fuel oil flow into tiny particles by both mechanical means the use of an atomizing medium. The oil and atomizing medium mix together in the atomizer and then flow to the oil tip to be discharged into the furnace.

BAG FILTER

A device containing one or more cloth bags for recovering particles from dust laden gas or air which is blown through it.

ENTRAINMENT

The conveying of particles of water or solids from the boiler water by the steam.

MICRON

One millionth of a meter, or 0.000039 in. or 1/25400 in The diameter of dust particles is often expressed in microns.

STRAINER

A device, such as a filter, to retain solid particles allowing the liquid to pass.

ABRASION

A general wearing away of a surface by constant scratching, usually due to the presence of foreign matter such as dirt, grit, or metallic particles in the lubricant. It may also cause a break down of the material (such as the tooth surfaces of gears). Lack of proper lubrication may result in abrasion.

ABRASIVE WEAR

Abrasive wear is caused by hard particles such as ash deposits, metallic particles or catalytic fines from the cracking process of the fuel oil. These hard grains wear down the surface of cylinder liners and rings by continuous ploughing and scratching.
With higher levels of abrasive wear, the surface displays vertical scratches, the size of which depends on the dimensions of the particles involved. These particles can also affect the sides of the rings as they jam in the ring groove, thereby causing "pitting" of the surface. Harmful particles normally enter the engine via the fuel and careful attention to the fuel cleaning system is therefore of utmost importance. abbrasive wear pic

CUTTING WEAR

Comes about when hard surface asperities or hard particles that have embedded themselves into a soft surface and plough grooves into the opposing harder surface, e.g., a journal.

ADSORPTIVE FILTRATION

The attraction to, and retention of particles in, a filter medium by electrostatic forces, or by molecular attraction between the particles and the medium.

AGGLOMERATION

Groups of fine dust particles clinging together to form a larger particle.
