Experimental Study on Water-Cooled Furnace Wall of Hazardous Waste Plasma Melting Furnace
The feasibility,heat transfer,and slag hanging characteristics of the water-cooled furnace wall of the melting furnace were studied on a 500 kg/d hazardous waste plasma melting system test bench,and it was applied on a 35 t/d industrial device.The results indicate that with the increase of water volume in the water-cooled furnace wall,the heat transfer increases and the thickness of slag hanging increases.As the total input heat in the furnace increases,the heat transfer also increases,but the thickness of slag hanging decreases.The thickness of slag hanging is 19-30 mm,and the heat transfer per unit area of water-cooled furnace wall is 20-30 kW/m2.The material disposal cost of the water-cooled furnace wall body has slightly increased compared to conventional refractory furnace walls,with an increase of 75 yuan/t and an increase of 3.75%.
