Since the calorific value of coal is one of the most important indicators in the analysis and analysis of coal, the calorific value of the coal calorimeter is relatively strict to the requirements of coal laboratories.
(1) The thermal chamber in the coal laboratory shall be used as a dedicated chamber for measuring calorific value, and no other test work shall be conducted indoors;
(2) Curtains should be provided indoors to avoid direct sunlight;
(3) It is advisable that the change of temperature does not exceed 1°C at each measurement; the difference between room temperature in winter and summer should not exceed 15~30°C. Therefore, conditions should be prepared air-conditioning equipment;
(4) When measuring the calorific value of coal, strong ventilation and heat radiation should be avoided indoors. In short, in order to reduce the influence of environmental conditions on the calorimetric measurement results, the calorific value measurement chamber should be kept as relatively constant as possible at room temperature. The calorific value must not be measured when the room temperature is not constant.
