CLL251 Heat Transfer for Chemical Engineering

Navneet Jha, Agrim Jain

Abstract: This report presents a novel approach to addressing two critical issues in India: the severe air pollution caused by the burning of agricultural crop stubble (parali) and the dangerous levels of indoor heat stress experienced in low-income housing. We propose the development and application of Rice Husk Ash (RHA) tiles as a low-cost, highly effective thermal insulation building material. By leveraging the inherently high porosity and silica content of RHA, these tiles significantly reduce thermal conductivity compared to standard construction materials. Experimen-tal validation using steady-state heat conduction tests demonstrates a substantial decrease in heat flux, validating the tiles? potential to passively cool homes while simultaneously creating a circular economic use for agricultural waste.
