Coal ash disposal is one of the main problems in thermal power plant unit. Currently, a number of waste management systems are being tried for effective disposal of coal ash. In this paper, coal ash from thermal power plant unit was successfully utilized for synthesis of mullite ceramic by using transferred arc plasma processing (TAP) technique. For this purpose, bauxite was added with coal ash by...
In order to increase a jet power and an operating duration time of the forced constricted type plasma jet generator developed by authors, newly designed divergent nozzle anodes were developed. The diameter of nozzle anode changed in two steps, i.e. the inner diameter increased stepwise from the inlet towards the exit. The effects of the nozzle configuration on the characteristics of the arc and plasma...
A newly designed plasma electrode-type plasma spray gun, which can generate a high temperature and clean plasma jet and inject various materials into the center of the arc column, has been developed. In order to demonstrate the application feasibility of this new-type plasma spray gun for thermal plasma processing, the effects of powder loading on the stability and temperature of the plasma jet and...
