Abstract

The usual rough estimate of sulphur emission was checked experimentally on the basis of the sulphur content in coal known as »burnt sulphur«. The measurements of the content of sulphur in stack gases proved that such an estimate based on the measuring of sulphur in ash known as »bound sulphur« under laboratory conditions of burning fuel up to 800°C, can result in an error of up to 100%. The emission of sulphur from solid fuel beds used for central heating comes to 90% while the supposed emission based on »burnt sulphur« should be about 50%. The sulphur emission from domestic stoves reached 56% to 88% depending on stove design, coal burning and on operating conditions. The emissions were always greater than the expected emissions of »burnt sulphur«. The results of these measurements indicate that we cannot rely only on the information concerning »burnt sulphur« content when the design and calculation of chimney emission and height is carried out, but the experimental data on sulphur balance should also be taken into account. Such data can be more and more often found in foreign technical literature.
