Optimization and characterization of hybrid bio-briquettes produced from the mixture of sawdust, sugarcane bagasse, and paddy straw.

Biomass briquetting is a viable densification technique that converts waste biomass materials into useful products and alternative energy. This work explores the characteristics and optimization of hybrid bio-briquette production by combining crop residues (paddy straw) and solid biomass materials (sawdust and sugarcane bagasse). A total number of 20 briquettes were fabricated with three input factors: sawdust (SD), sugarcane bagasse (SB), and paddy straw (PS) based on the faced-centered central composite design (FCCCD) approach in the laboratory to investigate the calorific value (CV) and ash content (AC).

Heat storage material: a hope in solar thermal.

Solar energy is a vast renewable energy source, but uncertainty in the demand and supply of energy due to various geographical regions raises a question mark. Therefore, the present manuscript includes a review to overcome this uncertainty by utilizing various thermal energy storage systems. Phase change material is the most preferred thermal energy storage system because of its high-energy storage density.

Effect of mass on convective heat transfer coefficient during open sun drying of groundnut.

In this work, an attempt is made to study the effect of mass on convective heat transfer coefficient (CHTC) for open sun drying (OSD) of groundnut ( L.). Experiments were conducted during the month of May, 2016 in the climatic condition of Rohtak, India (28°54'0″N 76°34'0″E).
