Apparatus for measuring the average temperature of a gas stream
Abstract
Abstract APPARATUS FOR MEASURING THE AVERAGE TEMPERATURE OF A HOT GAS STREAM, SUCH AS A COMBUSTION GAS STREAM, HAVING A TEMPERATURE GRADINT ACROSS THE STREAM AT RIGHT ANGLES TO ITS DIRECTION OF FLOW. THE APPARATUS INCLUDES A PROBLEM ADAPTED TO BE PLACED IN THE GAS STREAM, WHICH HAS INNER AND OUTER APERTURED CHAMBERS FOR MIXING GAS SAMPLES ACROSS THE GAS STREAM. THE INNER CHAMBER CONTAINS TEMPERATURE SENSING MEANS, PREFERABLY A PLURALITY OF PARALLEL-CONNECTED ELECTRICAL TEMPERATURE SENSING DEVICES DISPOSED WITHIN A TEMPERATURE-AVERAGING SLEEVE. IN THIS MANNER, FLUID SAMPLES ACROSS THE GAS STREAM ARE MIXED BEFORE A TEMPERATURE MEASUREMENT IS TAKEN AND SERVE TO HEAT THE SLEEVE TO A UNIFORM TEMPERATURE. AT THE SAME TIME, THE WALLS OF THE CHAMBERS SERVE AS A RADIATION AND CONDUCTION SHIELD FOR THE TEMPERATURE MEASURING MEANS SUCH THAT THE TRUE AVERAGE TEMPERATURE OF THE GAS STREAM CAN BE MEASURED WITHOUT INTERFERENCE FROM COLD WALLS, LUMINESCENT FLAMES AND THE LIKE.
