Abstract
A method of and apparatus for measuring the temperature of hot gases and/or particulate matter inside of a heated vessel is provided. The apparatus senses microwave energy emitted by the hot gases from the heated vessel, converts the sensed microwave energy into a signal indicative thereof, and measures the amplitude of the signal as an indication of the temperature of the gas inside of the heated vessel. The antenna of the apparatus may be located interior of the pressure wall of the vessel, and may also contain refractory material in it. Any refractory material between the antenna and the source of microwaves is transparent to microwave radiation. The heated vessel may also have a refractory wall, which may contain the waveguide and/or antenna.
