MEASURING APPARATUS OF ACIDITY OF COAL

摘要

PURPOSE: An apparatus for measuring the acidity of coal using an acidic solution such as a hydrogen peroxide solution is provided which can measure the acidity of coal quickly and at a high accuracy. CONSTITUTION: A apparatus comprises acidic and alkali solution pouring pumps (3a)(3b) for supplying acidic and alkali solutions to a reactor (2) which is filled with fully crushed coal; a stirrer (4); a device (5) for heating and cooling; positive and negative rods (6a)(6b) for removing oxidized material; a partition (2a) for separating the reactor and a oxidized material removing vessel (9); and a controller for controlling the feed rate of the acidic and alkali solution, the device for heating and cooling and a power source part (6). The apparatus reduces measuring time and promotes productivity.
