Title: Moisture measurement of decomposable products
Inventor: BACKMANN CLAUS
IPC: G01N5/04
Filed: 1988-03-01
Abstract: The moisture content of coal and other organic products which decompose and evolve gas when heated is effected by placing the product in a sample holder 3 in a microwave oven 1 and weighing the holder continuously on external scales 4 during the heating. Temperature sensors 8, 8A inserted in the product and one or more gas concentration indicators 9, 9A we mounted in an air discharge passage 10 of the oven. The highest temperature sensed (indicative of local superheating) regulates the oven heating. The gas concentration indicators are sensitive to different gases e.g. carbon monoxide, ammonia, sulphur dioxide and propane, butane and methane respectively, and their signals are constantly compared with first preset values to regulate the oven temperature and switch the oven off when they exceed second higher preset values. The slope of a curve correlating weight loss in successive time intervals against total weight loss changes when gas evolves enabling the total weight loss and hence moisture content to be predicted from the initial slope of the curve. <IMAGE>
