METHOD FOR OPERATING OF GASIFIER

摘要

PURPOSE: A gasifier operating method capable of accurately measuring the kinematic viscosity of slag is provided to control the temperature of the slag by measuring first and second flowing times of the slag. CONSTITUTION: A gasifier operating method comprises the following steps: measuring a first slag flowing time using a test system and a slag sample before storing(S310); measuring a second slag flowing time generated from operating the gasifier by inserting a marker into the gasifier and measuring the flowing time of the marker(S320); increasing the internal temperature of the gasifier or inserting a flux into the gasifier when the second flowing time is larger than the first flowing time(S350,S360); and decreasing the internal temperature of the gasifier when the second flowing time is smaller than the first flowing time(S380).
