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...

PROCESS AND TECHNOLOGY STATUS – Combustion boilers are widely used to generate steam for industrial applications and power generation. While all kinds of energy sources fossil fuels, biomass, nuclear and solar energy, electricity can be used to generate heat and steam, the scope of this brief is limited to combustion boilers using fossil fuels and biomass. Boilers can be grouped into two broad ...

This paper presents and analyses results from experimental and CFD work undertaken on a 24 kW domestic natural-draught gas fired boiler. The effect of chimney height on boiler flue gases is being considered to address the need for increasing concern over environmental safety as well as saving of energy. A multi-component analysis computer (DELTA 2000 CD) is used to analyze the flue gases. 3D nu...

Combustion control of an industrial stoker-"red boiler is to provide a continuous supply of steam at the desired condition of pressure. Because no e$cient mathematical model of the stoker-"red boiler is available, it would be very hard to design its controller by using any traditional model-based method. Therefore, the most widely used controller for the boiler system is a conventional PID-type...

The load following operation of coal-fired boiler-turbine unit in power plants can lead to changes in operating points, and it results in nonlinear variations of the plant variables and parameters. As there exist strong couplings between the main steam pressure control loop and the power output control loop in the boiler-turbine unit with large time-delay and uncertainties, automatic coordinate...
