14、ish Standard describes alternative methods of determining the total moisture on samples of coal taken and prepared by the procedures given in BS 1017-1. NOTEThe titles of the British Standards referred to in this standard are listed on the inside back cover. 2 Definitions For purposes of this Britis
15、h Standard, the following definitions apply: 2.1 total moisture the moisture in the coal as sampled 2.2 free moisture the moisture that is lost by the coal sample in attaining approximate equilibrium with the air to which it is exposed 2.3 moisture in air-dried coal the moisture in the coal sample a
16、fter it has attained approximate equilibrium with the air to which it is exposed 2.4 high rank coal a coal containing (arbitrarily) less than 4 % of moisture (in air-dried coal) and more than 84 % of carbon (dry, ash free basis) 2.5 low rank coal any coal other than a high rank coal. If the rank of
17、the coal is not known it is treated as a low rank coal 2.6 repeatability the maximum acceptable difference between single determinations carried out in one laboratory on two separate moisture samples taken simultaneously in accordance with the principles laid down in BS 10171) 2.7 reproducibility th
18、e maximum acceptable difference between single determinations carried out in different laboratories on two separate moisture samples taken simultaneously in accordance with the principles laid down in BS 10171) 3 Coal sample The sample for the determination of total moisture shall have been taken an
19、d prepared according to BS 1017-1. It will be received in the laboratory in a sealed, air-tight container and will consist either of 1 kg of coal having a maximum particle size of 13 mm or of not less than 300 g of air-dried coal having a maximum particle size of 3 mm. All samples, other than a 1 kg
20、 sample prepared from a coal having an initial top size of less than 13 mm or from a visibly dry high rank coal of any top size, will have been air-dried before receipt and details of the loss in mass on air-drying, i.e. the free moisture, will be recorded on the label of the sample container (but s
21、ee final paragraph of Foreword). 4 Moisture in the 13 mm coal sample 4.1 Distillation with toluene 4.1.1 Principle. This method is suitable for all coals. The whole of the 1 kg sample of coal is heated with toluene under reflux conditions. The toluene distils into a graduated receiver, carrying with
22、 it the water from the coal. The water then separates to form the lower layer. The excess toluene overflows from the receiver and returns to the flask. The moisture in the coal is calculated from the masses of the sample taken and of the water collected. 4.1.2 Special reagent. The following reagent
23、is required: Toluene. Boiling point 110 C, dry2). 4.1.3 Special apparatus. The following apparatus is required: Dean and Stark apparatus complying with BS 756 and comprising: 1) a copper flask, capacity two litres. 2) a receiver, capacity 100 ml. 3) a condenser and spray tube, as specified in BS 756
24、. 4) heating apparatus: the flask may be heated directly by gas or electricity, or by immersion in a heated oil bath. The receiver and condenser shall be cleaned before each determination by treating them with a suspension of potassium dichromate in sulphuric acid, or other suitable cleansing agent.
