Abstract
This work aims to improve the estimation of key performance indices (KPIs) in incinerator with ACS Company. The fuzzy approach is adopted to estimate KPIs on the basis of expert experiences which are difficult to quantify. The information from work field is translated into membership function with fuzzy logic in order to reflect the operating performance.he most dangerous place in an incinerator is the boiler at high pressure and temperature. A nonlinear dynamic model for natural circulation drum-boilers which can describe the complicated shrink and swell phenomena is used. In the aspect of energy input, the simulation of Municipal solid waste (MSW) with unsteady heating value and component is performed. On the other hand, open-loop test is also carried out. Various control strategies are realized in a simple way and combined with fuzzy KPIs. The results show that the newly proposed method is superior to the existing one in estimating KPIs. To sum up, monitoring the incinerator with fuzzy KPIs can well reflect the operating condition, and, therefore, every unit can operate safely.
