Abstract

PURPOSE:To measure exactly a temperature without being influenced by dust, by providing the shielding plates on the upstream side and the downstream side of a fluid by placing a thermometer between them. CONSTITUTION:A thermometer 1 is inserted into a passage of a fluid. A pair of shielding plates 2, 3 are semi-cylindrical, and are placed on the upstream side and downstream side of the thermometer 1, and an upstream side thermometer 4 and a downstream side thermometer 5 are placed on the outside thereof, respectively. A whitened arrow shows a gas flow of a free board part on a fluid bed, a dotted line arrow shows a flow of dust, and a temperature of an ascending dust itself is higher than a gas temperature, and on the contrary, a temperature of a descending dust is low. The dust does not hit directly against the thermometer 1, and the thermometer outputs a roughly constant gas temperature. On the other hand, the upstream side and the downstream side thermometers 4, 5 vary its output in accordance with the ascent or the descent of the dust, therefore, an action of dust can be known.
