High temperature processes are of vital importance in a number of industries, including cement, chemical, glass, metallurgy, refining and steel. With so many factors affecting the operational efficiency to consider, the stakes are pretty high for engineers to deliver a safe, reliable, efficient and environmentally friendly operation. That is why computational fluid dynamics (CFD) and reaction kinetic simulations of combustion processes to design systems are being increasingly utilized. They not only give the necessary insight into the complex physics but also help to significantly lower the cost of iterating between trials and prototypes. This is important when it comes to improving the current designs of processes and equipment such as gas and coal burners, glass and steel treatment furnaces, process and crude heaters, reformers and dryers and kilns.
