Aug 26, 2009 · The developed dynamic model was used to build up a drum boiler simulator for the typical Romanian steam boilers from a power plant being in use in the Iasi area. The model has been validated in open loop system, using data from tests carried out on the actual plant.
Pada boiler drum, air umpan yang masuk dengan tekanan 184 kg/cm 2 akan diturunkan menuju pipa downcomers yang kemudian terkumpul di pipa headernya dan diteruskan menuju wall tube (riser) untuk pemanasan lebih lanjut menjadi steam. Steam pada riser yang tentu saja memiliki massa jenis yang lebih ringan akan naik kembali menuju Boiler Drum.

Jan 01, 2014 · The simulation results for the drum-pressure and drum-level are then validated by comparing the same variables obtained in the plant-data. 3.1 Field data and model parameterization The main geometric parameters of our boiler-model simulator are configuration to match with the actual power-plant boiler by calculating drum-volume, down-comer
Oct 15, 2019 · In the present work, the overall behavior of a steam boiler is investigated using RELAP5/MOD3.2 system code at three different operating loads. Main thermal–hydraulic parameters are analyzed at steady-states corresponding to 60%, and 110% of the boiler nominal load. RELAP5 system code is widely used in the design and safety analysis of nuclear reactor installations as well as …
A plant validated boiler simulator is a very useful tool for controls design, analysis and performing experiments because of the cost involved in doing experiments on a real boiler or even lab-boiler.
