Abstract:
Design and development of a novel 22 kWth hot water generation system comprising a biomass-gasification unit in the core and an integrated fire-tube water heat exchanger in the annulus is reported. Producer gas from the gasifier is combusted in a burner and the resulting hot flue gases are routed back through the helical tube to heat the water contained within the annular shell. This allows recovery of the thermal energy typically lost from the outer surface of a conventional gasification system. The simple design improvisation leads to a doubling of the overall efficiency () compared to a standard system with physically separated gasifier and heat exchanger units (). The developed system holds promise in domestic and industrial water heating applications. Overall, this integrated design presents an efficient and environment-friendly waste-to-value concept and proposes a meaningful use of the underutilized 36 EJ/annum potential of biomass from crop residue globally.

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.
