The over-the-scope grasper (OTSG)

Endoscopy, 2020
Abstract Background Endoscopic removal of foreign bodies, coagulated blood, or necrotic debris is sometimes challenging and time-consuming, partly because of inadequate endoscopic instruments. Therefore, new devices are needed to overcome the current limitations.

Laboratory Evaluation of Scale Inhibitors Used in OTSG Boilers for Control of Silica Related Scale

CONFERENCE 2023, 2023
Abstract Natural gas-fired once-through-steam-generation (OTSG) boilers are commonly used to produce a large quantity of steam to enhance heavy oil production. Since approximately 80% of the feedwater is vaporized in a single pass, the risk of silica scale deposition in the boiler tubes can be severe when high-level silica is present in ...

Analysis of Flow Instability for OTSG Using Frequency Domain Control Theory

Nuclear Technology, 2010
Two-phase flow instability in parallel channels of a once-through steam generator (OTSG) is systematically analyzed by the modern frequency domain method. The mathematical expressions of heat transfer and flow for an OTSG are proposed, and the transfer function of the closed-loop system is deduced by the use of linearization and Laplace transfer.
