Abstract
World industry has an ever-increasing multilateral adverse effect on the natural environment. Pollution of the atmosphere, especially by fly ash, which is emitted by heating boiler plants on solid fuel, has reached an intolerably high level. In the power engineering of Ukraine, in accordance with the forecast, the share of solid fuel in its fuel balance will increase substantially. Consequently, the amount of fly ash removed by gases from boiler furnaces will increase. In the sphere of heating, which is abundant with heating boilers plants on solid fuel, the problem of reducing the release of fly ash has emerged. In accordance with the forecast, in the foreseeable future the problem will be aggravating. Its solution is possible by providing a high-efficiency process for ash capture in the site of the fuel combustion products removal from the boiler to the atmosphere. The complexity and scale of the problem аrе due to the difficulty in the disposal of finely dispersed ash particles from the furnace gases stream and the high number of heating boilers set. The problem contains a number of complex tasks: design and organization of manufacturing of new high-efficiency ash capturers (cyclones, scrubbers, electric filters), project design of sets of gas cleaning units on existing and constructed new boilers on solid fuel, introduction of new gas cleaning units. The solution of the problem of wide application of gas cleaners for solid fuel boilers should be based on the use of accumulated experience and on the results of new scientific and technical developments in this field. The study of the problem indicates the existence of opportunities to implement their solution in the foreseeable future. Thus, heating solid fuel boilers have an increasing harmful effect on the atmosphere. Further increase of the share of solid fuels in the fuel balance of the domestic power engineering strengthens the urgency of the problem of protecting the atmosphere from the pollution by fly ash. The problem of reducing ash emissions from solid fuel boiler plants has become urgent. Based on the experience of domestic power engineering and existing staff, research and production resources, the real possibility, in the foreseeable future, to reduce the degree of pollution of the atmosphere by ash from the heating boiler plants on solid fuels should be considered.
