SOME DONBASS ANTHRACITES RECLASSIFIED TO MEET MODERN REQUIREMENTS In conformance with the approved standard (GOST 5237-50), Donbass anthra- cites are classified according to the size of the lumps as follows: Slab AP > 100 mm Large AK 50-100 11 Nut AO 25-50 Fine AM 13-25 ? Pea AS 6-13 ASh LeSs than 6 Culm. In addition to these grades, the following grades of anthracite also exist: Run-of-the-mine anthracite with culm ARSh 0-100 mm Pea coal with culm ASSh 0-13 11 The GOST has also provided for separating an AZ class (anthracite rice coal) with the size of the lumps ranging from 3-6 millimeters. The indicated system of classifying Donbass anthracites was connected historically with the most efficient use of anthracite, according to grades, as fuel in installations of different types. A relatively short time ago, the layer method was the only one for the industrial consumption of anthra- cites and the chief consumers were railroad locomotives and plant-heating boiler installations. Boiler installations were provided with manually operated grates, often functioning without induced draft. Jr. proportion to the increase in capacity of stationary boilers, layer burning of anthracite on chain grates increased in practice. Fireboxes, designed specifically for layer combustion, operated -1 CONFIDENTIAL CLASSIFICATION EONFIDENTIAI, STATE NAVY NSRO DISTRIBl:TIO!I AIR f8' ARMY - -- - - Sanitized Copy Approved for Release 2011/08/25: CIA-RDP80-00809A000600400341-8 Sanitized Copy Approved for Release 2011/08/25: CIA-RDP80-00809A000600400341-8 1 CONFIDENTIAL CONFIDENTIAL successfully on graded fuel, and, when anthracite was used for layer combustion, was icalcr awhich make Pitdonefof anthracite use nh ys icochemchemi al properties for industrial combustion. Since a large nember of the manual.y operated. fireboxes operated without induced draft, it became expedient to burn large grades of anthracite in them becaust, in this case, very little resistance of the layer resulted. The AK, AO, and AM grades were selected for firet-or f ue: Further progress in the tech- nique of layer combustion, in conn-ction w_th the adoption of forced draft, has made it possible to use the smaller A`d grade ef,-ect!'%eiy- In Tsarist Russia, culm, the ASh grade f anthracite, was not utilized at alp.

Therefore, it is advsa` to rev'-se the existing system of classifying Donbass anthracites to conform to new mining and combustion condi- tions Mechanization of fuel combustion in industrial power engineering is spreading extensively at present. One of the principal characteristics of fire- boxer with stokers is their ability to burn a mixture of anthracites of differ- ent grades with the maximum size of the lump about 30 millimeters. The author suggests the advisability of creating a new anthracite grade, to be called AZM, to include lum,,s ranging in size from 3-25 millimeters and embracing the sum total of the AZ, AS, and AM grades. This new classification for anthracites wild reduce the culm content in anthracite mining since it would now include only lumps from 0-3 millimeters in size instead of lumps from 0-6 millimeters E'.ectri~_ power stations would not have to consume so much electricity in crushing the smaller lump culin supplied :, work to 1c san-e three grades would be to them: Grading plants would have i..?-- . combined in one.
