摘要： PROBLEM TO BE SOLVED: To cool water in a water tank located just below a slag discharge part in an ash melting furnace.
SOLUTION: A cooling water jetting nozzle is fitted into a slag discharge tube. The temperature of water in the slag discharge tube is prevented from rising by leading cooling water into the slag discharge tube. By this, the water in the water tank in the slag discharge tube can be prevented from being boiled due to the rise of the water and the temperature at the slag discharge tube and the slag discharge port from being lowered by evaporated water. Also, the water tank for producing granulated slag by cooling molten slag can be reduced in size. In addition, in the ash melting furnace using this invention, coal ash with high melting point and a large amount of ash can be melted.

摘要： PROBLEM TO BE SOLVED: To provide an ash melting furnace that can efficiently melt ash into slag.
SOLUTION: This ash melting furnace is provided with a device which can change the oxygen concentration in an ash transporting gas so as to raise the temperature of the gas by means of combustion heat generated by burning fuel with the oxygen enriched in the gas. The ash carried by the gas is quickly melted by the heat of the ambient gas and recovered as slag. Even when the quantity of the ash to be treated is increased, the quantity of the enriched oxygen can be reduced by locally raising the temperature of the gas in the existing area of the ash.
