ABRASIVE CONE

1. A solid having a plane base bounded by a closed curve and a surface formed by lines from every point on the circumference of the base to a common point or APEX. 2. A surface generated by a straight line of indefinite length, one point of which is fixed and another point of which follows a fixed curve. Also called a CONICAL SURFACE.

In a given direction, at a point on the surface of a source or receptor, or at a point on the path of a beam, the quotient of the luminous flux leaving, arriving at, or passing through an element of surface at this point and propagated in directions defined by an elementary cone containing the given directions, by the product of the solid angle of the cone and the area of the orthogonal projection of the element of surface on a plane perpendicular to the given direction. The derived unit of luminance in the International System of Units is the CANDELA PER SQUARE METER.

A valve generally used to continuously regulate concentration of solids in the boiler, not the drain valve.

A reversible process by which ions are interchanged between solids and a liquid. These ions exist throughout the solution and act almost independently.

An induction of boiler water caused by the steam flow into the steam line. The water may be in the form of a spray or a solid body.

A solid body of boiler water passed into the steam flow by priming or picked up from a pocket of condensate in the steam line.

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

Gas and solid products discharged from the stack.

Undissolved solids in boiler water.

The process of converting solid or liquid fuel into a gaseous fuel such as the gasification of coal.
