A series of improved active disturbance rejection controller (ADRC) methods are proposed, and their parameter tuning processes are presented. They are comprehensively compared with regular proportional integral (PI) control and ADRC, and detailed superheated steam temperature (SST) simulations are carried out to verify their notably superior control ...

Effect of Temperature on Penetration of Test Liquid into Boiler Pipe
Limitations of time in conducting superheater inspections during overhaul, allowing inspectors to conduct liquid penetrant testing activities above pre-determined temperatures. This results in results obtained from the superheater inspection tube boiler

Cyclopentane shows great potential as a working fluid for recovering gas turbine exhaust heat in organic rankine cycle (ORC) systems. A dynamic characteristics and control strategies analysis of a flooded ORC system using cyclopentane reveals that system safety can be ensured by adjusting the working fluid pump speed based on evaporator liquid‐level ...

Linear matching method for design limits in plasticity [PDF]
In this paper a state-of-the-art numerical method is discussed for the evaluation of the shakedown and ratchet limits for an elastic-perfectly plastic body subjected to cyclic thermal and mechanical load history. The limit load or collapse load, i.e. the

Achieving net‐zero or carbon‐negative energy systems requires technologies capable of generating power while capturing or utilising CO2 without significant efficiency losses. Molten carbonate fuel cells (MCFCs) offer such potential, yet their techno‐economic competitiveness across different energy systems remains insufficiently quantified.
