Marchenko Y. Development of estimation methods and operative control of technological properties coals for coking.

The results of theoretical and experimantal researches are protected in the field of an estimation of technological properties coal as raw material for coking. Developed the complex modified method adcoking and method laser destruction of organic weight coal and coal charge, which allow express to determine the mark coal and technological properties coal and coal change - caking property and heat stability. New parameters for a preliminary express estimation of a branded belonging coal on adcoking complex method and method laser destruction of organic weight are proposed. The laws of change of parameters termodestruction are established depending on different technology factors. A result of the profound study termodestruction connected polylayer of coal is reduced. The intervals of change of classification parameters coal termodestruction of the different marks and technological groups are determined that at different power influence the character of change of these parametrs does not change. The factors of the complex method adcoking can be used on separate coal-chemical enterprise at incoming for operative - go preliminary determination technological characteristic coals, coal concoction and coal blend. The method laser destruction organic mass of coal can be used in investigating purpose.
