1. Ranade (2002) has discussed previously some aspects of the approach. 1 Overall Approach The first essential step while developing an overall approach toward the computational modeling of PC boilers (or, for that matter, any other real-life process) is to clearly identify and define the goals for modeling. This appears to be quite obvious. Unfortunately, in practice, the causes of many not-sosuccessful performance enhancement projects may be traced to inadequate attention to this step. The goals of computational modeling are usually linked to the performance of the boiler.
Gas species are partially transported inside the coal particle. 0 toward oxygen. The typical operating temperature is 600°C to 1,400°C. Zone III: Bulk mass transfer of oxygen controls, or the particles are of large size. As the chemistry is fast, the reaction takes place close to the particle external surface area. 0 toward oxygen. The typical operating temperature is >1,400°C. It has been common practice to relate experimental char burning rates to the external char surface area, even when pore reactions can occur.
Recent advances in understanding multiphase flows, turbulence, and combustion, coupled with advances in computing power and numerical methods, provide an opportunity to develop an even better understanding of and better computational models for simulating coal fired boilers. Computational models for simulating total boiler performance can be grouped into two broad categories, namely (1) CFD-based models and (2) reaction engineering models developed using the insights and data obtained from the CFD models.
