Silica Scale Inhibition for Steam Generation in OTSG Boiler

Proceedings of SPE International Thermal Operations and Heavy Oil Symposium and Western Regional Meeting, 2004
Summary The production of extra-heavy oil or bitumen using the steam-assisted gravity-drainage (SAGD) method entails the generation and injection of a large quantity of steam into the reservoir. A similar quantity of hot water is produced together with the oil.

Analysis of Instability for OTSG by Using Multivariable Frequency Domain Method

Volume 4: Codes, Standards, Licensing and Regulatory Issues; Student Paper Competition, 2009
A new method for analyzing the problem of the thermal-hydrodynamic instability of OTSG (once-through steam generator) with multiple boiling channels is presented in this paper. The mothod is based on modern frequency domain theory and is more efficient for analyzing the instability of OTSG with coupling interactions and complicated boundary conditions ...

Mechanical integrity analysis of TMI-1 OTSG unplugged tubes

Nuclear Engineering and Design, 1984
Abstract Small I.D. circumferential defects have been identified in many steam generator tubes. The origin of the cracks is known to be chemical, not mechanical. A fracture mechanics evaluation has been conducted to ascertain the stability of tube cracks under steady-state and anticipated transient conditions.
