The invention belongs to the technical field of metallurgy, and provides a melting gasifier test device applied to scientific research and teaching. The device has a structure that the upper part of a furnace main body is provided with a feeding port and an exhaust port; the middle lower part of a furnace body is provided with a plurality of pressure measurement points; a pressure value and a pressure curve of each point are displayed on a computer; the middle lower part of the furnace body is provided with a gas distributor surrounding the furnace body; the outside of the furnace body is connected with a gas source; the inside of the furnace body is connected with a plurality of tuyeres; a spiral material discharger on the lower part of the furnace body is connected with blanking pipes on the tuyeres; and a dripping device is positioned on the upper part inside the furnace body, is controllable in position, and controls dripping speed through the height of water level inside. The device has the advantages of easily clarifying the distribution situation of airflow and hot metal in a furnace, clarifying the relationship between adjacent tuyere raceways, the influence of the tuyere raceways on the overall state of the furnace and the influence of dead-zone shape and dead-zone renewal rate on the state in the furnace and unfolding the process flow of operation, along with convenience for observation and operation, convenient equipment operation, use reliability, precise control and low failure rate.
