Improve Boiler Reliability With Unit Specific Strategic Planning
Volume 1: Fuels and Combustion, Material Handling, Emissions; Steam Generators; Heat Exchangers and Cooling Systems; Turbines, Generators and Auxiliaries; Plant Operations and Maintenance; Reliability, Availability and Maintainability (RAM); Plant Systems, Structures, Components and Materials Issues, 2014Boiler tube failures remain the leading cause of lost availability in power boilers across global markets. The need for strategic planning in regard to inspections, preventative maintenance and targeted replacements has never been greater. Identifying the root problem(s) is essential and must be properly managed for continued safety, reliability and ...

Backstepping-based nonlinear adaptive control for boiler-turbine units
2010 Chinese Control and Decision Conference, 2010Adaptive nonlinear backstepping controllers for a typical nonlinear boiler-turbine unit model with several uncertain parameters are presented in this paper. The first step consists in system model processing, which involves adding integral actions to the basic backstepping algorithm to obtain zero static errors.

Output tracking control of a nonlinear boiler-turbine unit
2004 43rd IEEE Conference on Decision and Control (CDC) (IEEE Cat. No.04CH37601), 2004The capability to perform fast load changes has been an important issue in the power market. An output tracking control system for improving the load-following capability of boiler-turbine units has therefore been developed. The system is composed of stable inversion and feedback controller.

Analysis and Control of Once-Through Boiler-Turbine Unit
Advanced Materials Research, 2013A nonlinear once-through coal-fired boiler-turbine unit model is introduced and analyzed for the purpose of control system design. Firstly, input-output variable pairing configurations for this 3×3 system are obtained based on static relative gain array and row-Gershgorin band analysis using its linearization model at 100% load.
