Superheaters are essential components in a coal-fired power plant because they keep the highest tube wall temperature points radiant boiler. The pressurized steam flowing superheater tubes is heated via thermal radiation and convection from combustion gas. To prevent bursting of caused by fatigue for stable safe operation, precisely predicting complex heat transfer characteristics, estimating l...

The aim of this study is to investigate the boiler tube failure mechanism using finite element analysis and experimental Analysis. numerical software used ANSYS steady-state thermal static structural analysis. independent variable for temperature from flue gas wall thickness tube. scope determine distribution, von mises stress, deformation safety factor by implemented design experiment. materia...

Abstract: The paper presents the research results related to control of the steam boiler parameters: drum level, furnace pressure and steam pressure. It was developed the mathematical model of the water-steam system and furnace part of the boiler. Also, the paper presents the algorithm for real time detection of model parameter variations. In this context a correction method, validate through s...

In this paper a neuro-predictive method is proposed in order to control the water level in the steam drum boiler system being in use at a Power Plant of Iaşi, Romania. The steam boiler provides thermal and electrical power and it works under complex technology in order to satisfy numerous technical, security and economical requirements. A nonlinear dynamic simulator for the proposed steam drum ...

Centrifugal heat pump has to be coupled with gas boiler to supply high temperature water in radiator heating system. Regarding to hybrid heating system (HHS), operation strategy has significant impact on its annual energy consumption and cost. In this paper, the optimal operation strategy of the HHS composed of sewage-source centrifugal heat pumps and gas boilers was analyzed. Firstly, the perf...
