Dunayevs'ka N. Impact of pulverised anthracite thermo-chemical preparation upon the changes of its properties.

High-ash antracite (HAA)/ To install the influence of the thermochemical preparation (TCP) on the properties of coke-ash residue (CAR), that allows to improve the ignition and combustion conditions of HAA when pulverised coal-fired burning,having economy of supplementary natural gas and oilfeeding. A method is that experimental determination of HAA' perfomances and CAR. There were made the new experimental and semi-industry installations. It is shown the delay time decreasing of HAA' ignition after TCP was mainly due to the particles' reactive surface increasing. The optimal TCP regime with best ignition and combustion properties have been established and approved at industrial-scale plants in furnace of boiler units/
