A novel, targeted approach to sootblower activation has been demonstrated recently at a large, T-fired, coal unit. Targeted sootblowing techniques are designed to activate blowers based upon the conditions of the boiler rather than a traditional time and/or sequence based approach. Various approaches have been used in the past to perform targeted sootblowing including neural network based model...
This paper considers an approach to design a controller used for the air-to-fuel ratio (AFR) optimization in the combustion process of a power plant boiler. The optimization of the AFR will reduce the excess air level and improve the combustion efficiency in the boiler system. The combustion improvement indicates boiler operating cost savings. The fuzzy logic controller, which is a method of a ...
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...
In steam power plant, the working medium used for energy transformation is water vapor. The generation process of vapor has experienced three stages: pre-heat, vaporization and superheat stage. There are five states in process. They sub-cooled liquid, saturated water, liquid-vapour mixture, superheated thermodynamic properties each state usually obtained by using tables charts. constant pressur...
