For reducing environmental impact and keeping the reliable operation of solid-fueled boilers such as pulverized coal firing ones, the prediction method of the emission and operation reliability is important. Due to the recent growth of computer performance, numerical simulation is effective for understanding the complex phenomena inside the boiler furnace. We developed the simultaneous evaluation method of the emission and operation reliability such as metal temperature, wall corrosion, and slagging characteristics by numerical simulation. This paper presents the validation results of our simulation method from the lab-scale furnace to the actual boilers. The developed method well captured the emission and metal temperature characteristics of the actual boilers.
