Steam generator temperature control

Deaerator – Purpose, Principle, Types, Process Control, Advantages …

2020/9/15 · Steam Pressure Control Deaerator uses Low pressure steam from the process plant at a pressure range between 0.5 to 1.5 bar . The low pressure steam sources may be any one of the following: Extraction from back pressure turbines, Flash steam recovered from Boiler blow down or Letdown steam from High pressure steam header through pressure reducing valve.

High Temperature Steam Applications - MHI-INC

Steam generators, like the GHGA, MHGA, OAB or HGA type routinely offer over 95% efficiency even to 1000°C and beyond (a temperature unimaginable for boiler steam). Temperature Limitations – Industrial boilers are temperature limited by pressure. To obtain higher temperatures, higher pressures are required. Not so for steam generators.

Heat Recovery Steam Generator - an overview | ScienceDirect …

Heat recovery steam generator is a high-efficiency steam boiler that uses hot gases from a gas turbine for reciprocating engine to generate steam in a thermodynamic Rankine Cycle. This system is able to generate steam at different pressure levels according to chemical process requirements (PGTHERMAL, 2009 ).

Optimize Steam Temperature Control Loops to Improve Availability. Increased cycling places additional mechanical stresses on boilers and heat recovery steam generators (HRSGs), particularly influenced by underperforming superheat and reheat loops. The suboptimal performance of these important loops can increase the frequency of tube leaks.
