Abstract
An improvement for a system used to measure temperature of hot gases that are laden with entrained solids. The system involves use of a pyrometer that is mounted outside of a sight hole through the wall of a vessel containing the laden hot gases. And, the improvement concerns a projecting shelf above the sight hole to divert molten slag in order to keep the sight hole clear. Also there is a sloped recess at the bottom of the sight hole to drain any slag away from the lower portion thereof.
