Abstract
A gas turbine, or like device which utilizes gas and is susceptible to damage from particles greater than a predetermined size in the gas stream, is protected by providing a cyclone downstream of a particle separator. If any particles are in the gas flow downstream of the particle separator--an aberrant condition--the cyclone will remove them and pass them to a particle trap, from which the particles flow to a measuring device. If the measuring device detects a significant number of particles, then an alarm is sounded or corrective action taken. The cyclone may be a horizontal cyclone, or a flow through cyclone.
