What is the calorific value of coconut shell?

The calorific value of coconut shells is approximately 19.6 MJ/kg (Megajoules per kilogram) on a dry basis. This indicates that coconut shells contain a substantial amount of energy that can be released through combustion. The calorific value of a material represents the amount of heat energy released when a specific amount of it undergoes complete combustion under controlled conditions.

Coconut shells are primarily composed of cellulose, hemicellulose, and lignin, which are all combustible organic compounds. When coconut shells are burned, these compounds react with oxygen to produce heat, carbon dioxide, water vapor, and other combustion products. The high calorific value of coconut shells makes them a potential source of renewable energy. They can be used as a biomass fuel for generating electricity, heat, or steam in various industries and power plants.

It's important to note that the calorific value of coconut shells can vary slightly depending on factors such as the moisture content, the origin of the coconuts, and the specific composition of the shells. However, the value mentioned above provides a general estimate of the energy content of coconut shells as a fuel source.
