Studies on Kolaghat Thermal Power Station fly ash with a view to set up a mechanised brick plant

This paper describes some of the efforts in finding means to put fly ash to some use in producing value added products . Some trials with fly ash from Kolaghat Thermal Power Station were undertaken at CGCRI, Calcutta by the author 's firm and a Japanese company to establish the possibility of putting up a mechanised brick plant, utilising clay and fly ash in different proportions which are briefed in the paper. From the studies, it is revealed that a mechanised brick plant, by replacing clay with flyash of similar characteristics as that of Kolaghat Thermal Power Station, to an extent of 50% can easily be installed. It also revealsthat a plan for producing 50,000 bricks or more per day will be a very attractive proposition.One could even consider a 25,000 bricks per day plant with some implications while selecting the equipments.
