The Design of a Large-Scale Induction Heating Power Source for Organic Waste Digesters to Produce Fertilizer

Abstract

Heating induction is a new environmentally friendly, energy-saving technology that offers a more effective performance than other common heaters. The energy-use efficiency of an inductor circuit is greater than 80 percent, while a biomass tank and tungsten coil have 70 percent and 51.8 percent efficiency, respectively. This method also produces more heat than any other forms of heating using gas or coal. The induction heating method has attracted significant interest and has seen application worldwide. Based on this important source of heating, we have designed and developed a large induction-heating machine with high energy to heat up a tank directly. The aim is to degrade organic waste as much as possible and convert it into an effective fertilizer by adding mesophilic microorganisms; the fertilizer transforming process takes no more than 24 h. The tank featured in our design has a 100-cm radius and is 155 in length; this is very large. The aim of this process is to reduce the amount of organic waste and thereby provide environmental benefits. To this end, we have designed a large, high-energy induction-heating machine (approximately 9.6 kilowatt) and used two machines in order to appropriately heat the tank for a large amount of organic-waste degradation. This research can be effectively applied to many heating methods in industry.
