Undeniably people's lives dependency on energy, has led to the importance of combustion knowledge. So far, one of the most important energy sources has been provided by burning. Much research has been done on understanding and controlling the combustion for more efficient usage. With the discovery of coal, use and research about solid fuel developed which led to important role of solid particles in research subjects.
As making particles smaller increases the ratio of surface upon volume, it can considerably reduce the amount of energy needed for volatizing and solid particle flammability. This research sheds light on theoretical study of multi-zones porous dust-cloud combustion. For better modeling of this kind of combustion and relating the previous analysis to experimental results, particle porousity has been considerably noticed. In the first chapter combustion concepts and preconditions, in second chapter literature review, in third chapter organic porous particle four zones conterflow combustion considering radiation as substantial effect, in forth chapter effective forces in particle displacement including thermophorecis force, in fifth chapter combustion of single porous solid particle, in sixth chapter the combustion modelling of coal dust-cloud in counterflow geometry and in the seventh chapter, the oscilisation and unstability of sixth chaper combustion flame have been investigated. Subsequently, eighth chapter presents the conclusions, novelties and suggestions of the study
