Quality reducing properties of Hungarian brown coals
Hungarian brown coals of different ages and from different mines were examined. On the basis of elementary analysis it can be established that the maturity of Hungarian brown coals is lower and their total sulfur content is higher than that of foreign coals. A part of the total sulfur is included in...

| 520 | 3 | |a Hungarian brown coals of different ages and from different mines were examined. On the basis of elementary analysis it can be established that the maturity of Hungarian brown coals is lower and their total sulfur content is higher than that of foreign coals. A part of the total sulfur is included in pyrite form but it is very likely that the larger part of the sulfur content is organic sulfur. During combustion of these coals the largest part of the organic sulfur and a part of the pyrite sulfur gets into atmosphere as combastible sulfur. For reasons of environmental protection the experiments should be contained to reduce the amount of the sulfur dioxide getting into the atmosphere to minimum value. | |
