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 title of the paper purports to discuss the feasibility of 100% RDF firing for power generation. It is implied that it is possible to fire 100% RDF in a single boiler. However, for the case study cited, the author suggests a much more elaborate system for a 16 MW system. The flow sheet suggests 80% heat input from RDF and 20% from coal. He also suggests that three boilers handle the RDF. Thi...

Every six months or so the majority of steamdriven ships spend a few days in docks having their boilers scaled and cleaned. In the larger docks there are men who are employed full time in this occupation, but elsewhere and in industry generally the cleaning is more often done as an occasional job. The total number of men engaged in the work full time is not large, but the occupation is a very d...

This paper presents the application of finite element method (FEM) to analyze the tube temperature distribution in a water tube boiler. Two-dimensional (2-D) finite element models are developed where the axi-symmetric triangular elements for the cross section area along the water tube are applied in computer software namely MSC Patran-Nastran. The analysis of the temperature distribution for ev...

The fluctuation in temperature and pressure boiler parts subjected to creep fatigue stress also fuel burnt steam generation leads corrosion various areas the boiler. Residual during manufacturing, vibration due flow over tube, mechanical vibrations, erosion abrasive nature of fuel, does occur boilers. All above, individually or combined lead material degradation different magnitude will failure...

We report a case of endotracheal tube fire occurring during CO2 laser surgery of the larynx. The ignition of an endotracheal tube was thought to be caused by laser penetration of an unprotected portion of the tube during resection of vocal cord tumour. Fire hazard is inevitable when a laser is used in the path of combustible gases and in the presence of flammable objects. We discuss the methods...
