Absorption of co2 from cotton stalk incinerator

Renewable energy has obtained considerable interest as the fossil fuel reserve is getting shorter with a remarkable effect on the environment and global warming. Those resources are inexhaustible and cheaper than the fossil fuels. In Gezera of Sudan, cotton stalk is very huge in quantity and quality as cotton is one of the national crops planted and its fiber is used in textile industry and for export. However, there are worms that attack the roots of cotton and affect the quality and quantity of the product, therefore the cotton stalk must be derooted and burnt. The burnt is made in open areas of the field with evolution of CO2 which affects the nearby residential areas with simultaneous effect on the environment. The aim of this paper is to collect the cotton stalk in bundles, and introduce it into a well-designed and controlled incinerator provided with a boiler for steam production and electricity generation, which can be supplied to the residential area and villages. It must be recognized that one kilogram of cotton stalk gives 17.1MJ, in addition of utilizing the ash residue as a fertilizer. The absorber dimensions are: out inside diameter 0.52m, thickness 7.5mm, outside diameter 0.5275m, overall height of 2.6m.
