An improved apparatus and means for measuring temperatures inside enclosures or conduits containing hot gases laden with entrained solids using a pyrometer. The improvement involves an optical access port consisting of a high strength sight tube, a safety valve, a double sight glass, various purge connections and provisions for optical alignment. A dynamic purge system keeps the optical sight path clear during normal operation, and clears the path if it begins to become occluded during operational upsets within the enclosure or conduit. The improved optical access port is mounted on the exterior wall of the vessel or conduit.

The combination with a reactor for reacting a hydrocarbonaceous mixture in the reactor\s reaction chamber to produce a synthetic gas and particulate matter, said reactor being characterized by an internal wall, a refractory lining about the reaction chamber and a borehole traversing said liner from a port in the reactor wall and opening into the reaction chamber, a removable sight tube assembly positioned in said borehole to afford visual access to the reaction chamber to conduct radiation therefrom and comprising an elongated tubular element defining an internal cylindrical sighting passage having a face and an inner open end, and an outer open end, and being positioned in said borehole to define a second, annular purge gas passage between said tubular element and said borehole, said elongated tubular element longitudinally registered in said borehole whereby the face at the inner open end thereof lies in a plane common with the reaction chamber wall, a toroidal, manifold attached to said outer open end of said elongated tubular element and having an inlet communicating with a pressurized source of a purge gas, and at least one discharge port communicating with said annular purge gas passage, a shut-off valve having an inlet attached to said manifold, which, when open, affords straight line-of-sight visual access through the valve and the elongated tubular element, and having an outer end, a second toroidal, manifold attached to said outer end of said valve and having an inlet communicable with a pressurized source of purge gas, and at least one discharge port communicated with an axial space enclosed by the second toroidal manifold, said axially enclosed space being immediately contiguous with the interior space of the shutoff valve which, in turn, is in connection with a cylindrical gas passage defined by the tubular element, a spool piece containing two coaxially aligned sight glasses attached to the second toroidal manifold and, in cooperation with the second toroidal manifold, the shut-off valve, the first toroidal manifold, the tubular element, the various gas sources and supply lines and the reactor, forming a gas tight enclosure, said spool piece including a small, sealed, gas-tight enclosure between said two coaxially aligned sight glasses, where said enclosure has an inlet communicable with a pressurized source of a gas, and a optical alignment element connected to the remote end of said spool piece providing a means for attaching and optically aligning a pyrometer or any other such radiation receiving device for the purpose of measuring the radiation emitted by the gaseous and particulate material contained within the reactor.
