Experimental Investigation of Eco-Friendly and Energy Efficient Auto and Allo Thermal Charcoal Kiln

Like many countries in India, Charcoal production is the primary employment for rural masses in most of South Tamilnadu. It is a foremost source of income and environmental degradation in rural regions. The yield and transport of charcoal are a precarious process with energy and economic cycle. This process emits greenhouse gases to the atmosphere. It frequently made in traditional charcoal method that are harmful to the environment. It requires efficient man power for completing the process. The quality and yield for the conventional method is very low because of prolonged time. This method is mostly practised in rural areas. People over there will be more concern about quantity not the quality. So this reduces the yield of the charcoal. In this eco-friendly concept time consumption is reduced and hence yield will be more than the conventional method. In this paper, the indirect heating kiln has been tested with prosopis juliflora wood and the results were the lowest ash content of less than 2% and fixed carbon content of greater than 75%. The temperature was in range of 400-600° C inside the kiln which helps to understand the process of pyrolysis reactions.
