Investigation of the optimal parameters for repair welding of the coal mill in the fossil power station
(Welding in the World, 2008)
As a part of the coal fired power stations a coal milling plant is important, as it supplies a coal and air mixture for combustion in a power plant. Coal milling plant is involved in wearing process, since the raw coal is ...
Comprehensive approach to the influence of frequently used secondary raw materials on clay bricks quality using mathematical modeling (a systematic review)
(Elsevier Sci Ltd, Oxford, 2018)
The main idea of this research was to evaluate rice and sunflower hulls, sawdust and their ashes, as additives in clay brick production using mathematical analysis. All available papers, containing the parameters of interest, ...
