Solar chimney can be used to dry agricultural products, foodstuffs, bio residues. One of the problems with bio-residues is its high moisture content. This present work aims at studying the effect of new type of solar chimney for drying goat waste. The experiments were conducted by natural circulation mode as well as forced circulation mode with chimney area of 0.342 m2. The experiments were also repeated with fixing radial fins at the outside of the chimney.

The world is largely dependent on fossil fuels for its energy demand. However, fossil fuels are depleting at a faster rate. They are turning out to be unaffordable due to its limited resources and their huge demand. Above all, fossil fuels are highly polluting the mother earth. Thus, the need of the hour is to look for an alternate energy source which can cover up limitations of fossil fuels. Research on biomass emphasis that biomass can effectively substitute fossil fuels. There are many routes for recovering energy from biomass. Apropos, hydrogen is believed to be the fuel for the next...

Pyrolysis and gasification processes, the two most widely used processes of energy conversion from biomass have been practised by mankind from time immemorial. However, it is after the crude oil crisis, the research world envisaged that these processes are very important to extract energy through alternate means of energy recovery from biomass. As the study on pyrolysis and gasification is enthralling and offering bright scope, many researchers have started to work on pyrolysis and gasification. Thus, the need of the hour is to disseminate some basic fundamentals about pyrolysis and...
