LEAKAGE PROTECTION SYSTEM, PRESSURE BALANCING SYSTEM, AND PRECIPITATOR WITH VALVE FUNCTION FOR ABLATION APPLICATIONS

摘要

An ablation device (1), comprises a boiling chamber (42) adapted for boiling an ablation medium for ablating material from an object; an ablation medium drain line (46, 32) adapted for draining the ablation medium received from the boiling chamber (42); a flow impedance (44) arranged between the boiling chamber (42) and the ablation medium drain line (46, 32); an ablation medium conveying unit (62) adapted for conveying the ablation medium to the boiling chamber (42), through the flow impedance (44) and to the ablation medium drain line (46, 32); wherein the ablation medium conveying unit (62) and the flow impedance (44) are adapted so that the ablation medium has an average flow velocity in the flow impedance (44) of at least 50% of the acoustic velocity.
