A new concept slagging gasifier is tested in a 200kg/day scale facility. The new slagging gasifier is the pebble bed gasifier, which contains a fixed ceramic ball bed under an entrained bed. Gasification medium is high temperature air of about 1000°C added with steam. The gasification pressure is atmospheric. Pulverized Datong coal and crushed Skyline coal were respectively gasified in this facility. The gasification performances were evaluated by the cold gas efficiency and the carbon conversion rate. In the pulverized Datong coal gasification test, the achieved calorific value of the syngas was 4.970MJ/Nm3 (1187kcal/Nm3), where the cold gas efficiency as high as 78% was demonstrated.
