Description

technical field [0001] The invention relates to multiphase flow testing technology, in particular to a capacitance probe testing system and a method of using the same, in particular to a capacitance probe system suitable for a supercritical water fluidized bed and a method of using the same. Background technique [0002] Supercritical water gasification technology is a very promising technology for clean and efficient utilization of organic resources such as coal / biomass developed in recent years. It has high reaction efficiency and zero pollutant emissions. As a new type of coal / biomass gasification reactor, supercritical water fluidized bed realizes the continuous gasification of coal / biomass in supercritical water, the reaction material heats up rapidly, enhances heat and mass transfer, and is easy to discharge slag. However, up to now, the microscopic two-phase flow characteristics in supercritical water fluidized bed reactors are still poorly understood, mainly due to t...
