Plants for the pyrolytic combustion of textile waste with an energy recovery system
The project aims to demonstrate the possibilities offered by the pyrolytic combustion of waste produced by the raising and cutting of various textiles. The plant used for the demonstration has a processing capacity of 2,000 kg of textile waste per day. The waste is made up of a mixture of cellulose and synthetic fibres (with a lower calorific value of 25,000-27,000 kJ/kg on average). The project, which took place over a period of six months, following the development of the plant, has shown that: - The heat dissipated to bring the oven up to its operating temperature, with the fuel which is traditionally used (GPL), corresponds on average to 2,000 kJ/kg of waste burnt. - The total heat recovery on 2,000 kg of waste burnt is approximately 30,000 MJ. - The electricity dissipated by the plant, excluding that which relates to the diathermic oil circulation pumps, is approximately 0.15 kWh/kg of waste burnt. The conclusions of the project are that: - The technology is technically valid, provided that materials which are suitable to the operating conditions of the oven are used. - Economic viability depends on the cost of processing the waste (which must exceed 180 Lire/kg) as well as on the cost of conventional fuel (at least 400,000 Lire/tep). - The minimum capacity of the plant should preferably be no less than 3,000 kg of waste processed per day.
