    Abstract:

Applications: Improved Up Draught Pottery Kiln Pottery making is a traditional craft in villages for making clay utensils and various artifacts. These furnaces are highly polluting and inefficient. The improved design of the pottery kiln is more efficient and less polluting.
Advantages: Demand Driven Technology: The pottery kilns in the village are updraft kilns, cylindrical in section, typically 5 feet in diameter and 5 feet deep. The ware is placed on a grate, along with pieces of dried cow dung cakes which are a source of heat for firing. The ware is then covered with broken pottery pieces to improve the retention of heat in the kiln. The firing is done by burning light, low density biomass typically comprising of agro waste such as crop stalks and husk, which is painstakingly gathered and stored by the families of the potters during the harvest season. Sometimes they also purchase the fuel for use in firing. Since the firing is done by burning low density biomass, it burns off fast, and so it needs rapid feeding of fresh fuel. Since the kilns are not scientifically designed for adequate air supply, rapid feeding results in smoky combustion of the fuel. In addition, since this heat is used to ignite the cow dung cakes stacked above the grate, it is even smokier: the pyrolysis of the cow dung cakes releases more smoke, making the process even more polluting.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
