In autumn 2017, an experiment was conducted for the reduction of carbon monoxide (CO) emissions commissioned by Holmen Paper Braviken, one of the world’s most production-efficient paper mills. Digitalization has increased in recent years, which has resulted in a decreased demand for graphic paper. The goal of finding cost-reducing solutions in the manufacturing process has been increased in Hol...

Metal temperature is to be known at boiler design stage for material selection. Experimental metal temperature data collected at supercritical water conditions. ANN model developed using experimental data for metal temperature prediction. 100% agreement at ±7 C deviation for experimental data. 97.22% agreement at ±10 C deviation for literature data. 120

Power generation today is an increasingly demanding task, worldwide, because of emphasis on efficient ways of generation. A power station is a complicated multivariable controlled plant, which consists of boiler, turbine, generator, power network and loads. The power sector sustainability depends on innovative technology and practices in maintaining unit performance, operation, flexibility and ...

This paper is concerned with the study of drum water level control using the well established single element and 3 element controllers. The study is based on the ÅströmBell (A-B) interpretation model of the boiler, which is used to simulate a 160 MW plant P16-G16 in Sweden and a 500 MW plant WW500 in Australia.

This work describes a large reclaimed water source heat pump system (RWSHPS) and elaborates on the composition of the system and its design principles. According to the characteristics of the reclaimed water and taking into account the initial investment, the project is divided into two stages: the first stage adopts distributed heat pump heating system and the second adopts the combination of ...

Corrosion-fatigue, a cracking mechanism in fossil-fueled generating plants, predominately occurs in the water walls and economizers of sub-critical plants. Cracking attributed to corrosion-fatigue has occurred in water wall tubing of both membrane and tangential designs. The occurrence (particularly in membrane water wall tubing) presents a challenge for nondestructive evaluation (NDE) because ...
