Quality regulation of the combustion process inside the furnace is the basis of high demands for increasing robustness, safety and efficiency of thermal power plants. The paper considers the possibility of spatial temperature distribution control inside the boiler, based on the correction of distribution of coal over the mills. Such control system ensures the maintenance of the flame focus away...

This work presents the simulation of a steam generator or water-tube boiler through implementation in MATLAB® for proposed mathematical model. Mass and energy balances three main components boiler—the drum, riser down-comer tubes—are presented. Three alternative solutions to ordinary differential equation (ODE) were studied, based on Runge–Kutta 4th order method, Heun’s MATLAB function Ode45. T...

The average enterprise network operator is responsible for managing a network that secures $5 billion worth of intellectual property (McAfee 2010) and whose poor performance can result in the loss of $100 million in operating revenue (InformationWeek 2007). My current and future research are motivated by the importance of such networks and focus on developing fundamental models that make them e...

This paper studies a planning problem for heating water. Hereby, boilers (e.g. gas or electric boilers, heat pumps or microCHPs) are used to heat the water and store it for domestic demands. We consider a simple boiler which is either turned on or turned off and has a buffer of limited capacity. The energy needed to run the boiler has to be bought on a day-ahead market, so we are interested in ...

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 ...

According to the characteristics of boiler combustion process, we use image processing technique to extract features that characterize the features of flame. On requirements of good real-time performance boiler burning diagnose system, we develop a set of PC add DSP real-time image acquisition and burning diagnosis system on the 200MW boilers. The results show that the system is simple, practic...

An adaptive predictive control methodology is applied for a fossil fuel boiler control. The control algorithm takes advantage of a neuro-fuzzy identifier system for prediction of the boiler response in a future time window. An optimizer algorithm based on evolutionary programming technique (EP) uses the identifier-predicted outputs and determines input sequence in a time window. The present opt...

National Thermal Power Corporation (NTPC) has signed an MoU with Bhabha Atomic Research Centre (BARC) for design and development of automated boiler tube inspection system for vertical water wall tubes. A vertical climbing robot has been developed for this purpose at Division of Remote Handling & Robotics (DRHR), BARC. Recently, an Electromagnetic Acoustic Transducer (EMAT) has been integrated ...
