Microwave ignited combustion of Coal with maize slush and waste cardboard in modified Tube furnace Y.I.Tosun 1,* 1 Department of Mining Engineering, ùﾕUQDN 8QLYHUVLW\, ùﾕUQDN, Turkey Abstract The microwave heating applications in various fields and materials could be managed, such as contaminated soil remediation, waste processing, minerals processing and activated carbon regeneration. Microwave heating of volatile organic compounds (VOC) by synthetical heating susceptors in microwave. The microwave combustion technology could be improved for lignite and biomass in the packed bed systems. This may include few difficulties associated with the scaling up of laboratory units to industrial process depending on material dielectric properties. The combustion process by microwave may have specific advantages over conventional methods with cost of heating. Keywords: Microwave ignition; coal combustion; packed bed; microwave heat flux. 1. INTRODUCTION The heat values of biomass potentially recycled in the world for a renewable source bring out necessity in use by mixing or a self preference on combustion biomass wastes in the country. The total thermal values based on the products for maize, wheat and cotton are 33.4, %16.1% and 27.6%, respectively. In Table 1, the total annual production of horticultural crops in Turkey is given. The total thermal values are approximately 13,5, 14,8 and 21.5 kJ/kg, respectively. As given in Table the total calorific value of the product nut shells and olive seed were 56.3% and 25.2%. The potential calorific value of the potential amount of pitch waste and animal waste could be determined and true and theoretical values of heat for cows, sheep and poultry, which is about 36, 13 and 6.5 million tons/a in Turkey for cows.
