A method of particle collection in which the particle carried by a gas stream collides with a fiber and has enough inertial force so it does not deflect along with the gas stream.
The physical contact of gas- laden flow against a filter media. Typically referring to an abrasive wear caused by this impact.
INCHES OF WATER
A unit of pressure equal to the pressure exerted by a column of liquid water 1" high at standard conditions (70°F. at sea level); 27.7" of water equals 1 psi; usually expressed as inches water gauge (W.G.) or inches water column (W.C.).
An instrument using a liquid column, set at an incline to increase sensitivity and pressure reading accuracy. It is normally used to measure velocity pressures in a duct.
The stream of fluid entering the filter.
The pressure entering the inlet side of the filter. Also called upstream pressure or line pressure.
Particles are collected on the inside surface of the bag (most reverse air and all shaker baghouses).
The process of measuring, examining and testing to compare a characteristic of an item with specified requirements.
The opening between the interfacings of the warp and filling yarns; i.e. the voids in the fabric.
International Standards Organization. It is the specialized international agency for standards' making; with membership of over 90 countries.
A sampling of the flue gases drawn from the mainstream of the gas into the sampling apparatus with no change of velocity.
