The temperature control of the reheat furnace is very difficult due to its complex characteristics. Based on expert knowledge and pyrology mechanism, a hybrid supervisory control system (an optimal setting model) has been developed innovatively to control its temperature. With the help of a statistical process controller, this hybrid supervisory control system can replace the human operator for...

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...
