Modern heating furnaces use combined modes of the charge. At high temperatures, more radiation is used; at lower convection used. In large furnaces, such as pusher it necessary to monitor material zonally. Zonal allows appropriate thermal regime be set in each zone, according desired parameters for The problem furnace optimum so that end heating, after has been cross-sectioned, there a uniform ...

So far, the accurate modeling and control of blast furnace iron-making process (BFIP) is still an open problem due to its excessive complexity. Aiming at the issue of long time-delay and strong cross-coupling characteristics of BFIP, the random forests (RF) algorithm is introduced for predicting the silicon content in hot metal, which is the most key indicator of inner state of blast furnace. I...

Understanding of how and where NOx formation occurs in industrial boiler is very important for efficient and clean operation of utility boilers. This study aims to numerically simulate the NOx formation using a 3D model furnace of an industrial boiler. The studied boiler is a 160 MW and is gas fired with natural gas. The boiler combustion model is a 3D problem that involves turbulence, combusti...
