Get priceNov 14, 2021 · The heat transfer for the boiler water wall was considered to be the thermal wall boundary condition. Therefore, 653 K, which is the average steam temperature of the water wall, was set as the external temperature, and the convective heat transfer coefficient was assumed to be 500 W/(m 2 K). In addition, 0.85 was used as internal emissivity.
Get priceOct 18, 2017 · Finally, the operation simulation of the water-steam flow of the once-through boiler was performed for the case of dynamic step-down from the supercritical pressure to the subcritical pressure. Once-through steam generator systems with supercritical fluids are applied to achieve large capacity and high efficiency in power generation systems.
Get priceTangential-firing boilers develop large swirling fireballs by using pulverized coal and air from the corners of the burner zone. During operation, however, the boiler may experience an uneven air supply between corners; this deforms the fireball, raising various issues concerning performance and structural safety. This study investigated the characteristic boiler performance and the role …
