Abstract
For producing controlled precipitation in fluid flowing through a pipe, a coil of electric wire is applied to the pipe segment in which this controlled precipitation is to be produced. This coil may be in the form of an induction coil wrapped around the pipe. Or the coil may be of a flat, rectangular spiral form. In any case, the coil is applied in such a way that the center of its curvature does not coincide with the pipe axis. Instead, this center of coil curvature is offset from the pipe axis. Preferably, this offset is approximately equal to the radius of the pipe.
Claims20
Apparatus for reducing scale formation inside a fluid-flow carrying pipe, the pipe having a generally circularly-shaped wall and a hollow interior passage and having a longitudinal axis substantially parallel to the direction of fluid flow, comprising:
- means positioned so as to curve at least partially around a segment of said pipe, for inducing a time-varying magnetic field in said pipe in response to an applied time-varying electric current;
- said means being so constructed and arranged that its center longitudinal axis of curvature is not concentric with the longitudinal axis of said pipe segment.
