Utilization of coal-water fuel in heat power industry and by public utilities of Ukraine
One of the major problems of the fuel and energy balance of Ukraine is acute shortage of its own resources of organic fuel. At present the steam coal output in Ukraine approaches 100 mln t, oil production makes up about 5 min t and that of gas reaches 22 bln. m{sup 3}, which in terms of equivalent fuel (e.f ) totals 94 min t, the annual demand being approximately 300 mln t e.f. To make up for fuel deficiency Ukraine has to annually import 120 bln. m{sup 3} of gas, 50 mln t of oil and about 10 mln t of coal, their approximate cost being U.S.$ 15.6 bln. At the same time coal reserves in developed fields only make up 10 bln. t, the total reserves of this fuel being 100 bln. t. Thus the whole burden of meeting the requirements of Ukraine in power resources when nuclear power plants capacities are being reduced and expected to be reducing in the nearest future falls on coal. Under wasting conditions a problem of today is to develop and introduce new technologies of coal mining and utilization with due regard for technical, economic and ecological aspects which are particularly important for densely populated industrial regions. Ecological problems associated with a dramatic increase in the volume of coal combustion can be solved by developing new methods and means for flue gas cleaning in the first place and by wide-scale introduction of coal-water fuel (CWF) in the second place. Investigations have shown that the second way is more preferable since it is based on the integrated technology for original coal demineralization and CWT production, advantages of each process being used in full measure. Thus demineralization of coal is among major requirements to development of a CWT production technology.
