Analytical model for erosion behaviour of impacted fly-ash

Fly ash particles entrained in the flue gas from boiler furnaces in coal-fired power stations can cause serious erosive wear on steel surfaces along the flow path. Such erosion can significantly reduce the operational life of the boiler components. A mathematical model embodying the mechanisms of erosion on

Mathematical modelling of a steam boiler room to research

Downloadable (with restrictions)! This paper introduces a mathematical model of a boiler room to research its thermal efficiency. The model is regarded as an open thermodynamic system exchanging mass, energy, and heat with the atmosphere. On those grounds, the energy and energy balance were calculated. Here I show several possibilities concerning how this model may be applied.

Mathematical Modelling and Design of an Advanced Once

Mathematical models for conventional boilers are usually based on empirical equations corresponding to each region of the boiler: the economizer, the boiler and the superheater. Those three parts of boiler are clearly separated thus it is not difficult to choose the appropriate equation.

A dynamic mathematical model of an ultra-supercritical

Downloadable (with restrictions)! It is challenging and interesting to establish a precise dynamic model of an OTB (once-through boiler) power plant unit in order to meet large scale load demands from the power grid. This study proposes to establish such a dynamic mathematical model of an ultra-supercritical OTB unit under dry operating conditions.
