Modeling a thermal power plant drum-type boiler for

boiler. This model is obtained based on thermodynamics principles and energy-mass balance, also parameter estimation routines applied on the experimental data obtained from a specific power plant. Next, for vigorous control studies, a concise multilayer neuro fuzzy model of the boiler is developed. Then, these two models are compared based on the

Modelling and simulation of fluid-flow and heat transfer

The model was used to analyze pressure drops and resulting fluid saturation temperatures throughout the loop. Good agreement was found between predicted fluid mass flow rate and that measured in a lab-scale loop thermosyphon prototype. The model continues to be developed and will be validated against a larger-scale prototype system. Introduction

Symptoms: Aggressive localized boiler tube corrosion and loss of tube wall.Pits can act as stress-concentration sites which can be initiation points for stress-related corrosion mechanisms. Causes: Oxygen pitting occurs with the presence of excessive oxygen in boiler water.It can occur during operation as a result of in-leakage of air at pumps, or failure in operation of preboiler water

Performance Optimisation of Coal-fired Boiler Control

Sep 22, 2016 · Specifically, I have a model of a boiler using the DynamicPipe component, and I then just transfer heat to the pipe to warm up the water inside it, and employ a pump component to control the pressure difference over the entire boiler. The model compiles just fine to an FMU using JModelica and I am able to simulate it without any problems.
