ABSTRACT:
A temperature measuring device for a gasifier of a gasifier system wherein the gasifier has a through opening formed thereon. The temperature measuring device includes a slag shield mounted on the gasifier so that a portion of the slag shield extends into the interior of the gasifier through the opening with which the gasifier is provided for this purpose, and a temperature measuring instrument mounted in supported relation within the slag shield so that a line-of-sight exists from the temperature measuring instrument into the interior of the gasifier whereat the temperature is desired to be measured. The slag shield is designed to protect the temperature measuring instrument from the slag flow within the gasifier. The temperature measuring instrument further includes cooling means for cooling at least that portion of the slag shield that extends into the interior of the gasifier, and purge gas means for supplying a flow of purge gas in surrounding relation to the temperature measuring instrument to purge particulate matter therefrom in order to ensure that the line-of-sight between the temperature measuring instrument and the interior of the gasifier remains unobscured.
