A result of poor superheater design (Photo1). Superheaters in power generating boilers play a critical role in sustaining maximized power generation and overall boiler performance. Superheater design not only impacts the final steam temperature but also the expected steam drum pressure, the potential for elevated tube temperatures, corrosion and erosion
In this post, we build on Part 1 of How Hot Can you Go?, a discussion on feedwater temperatures entering the steam drum. Although hotter feedwater temperatures result in increased steam generation for the same fuel heat input, feedwater temperatures that are too close to the drum saturation temperature can
The amount of steam generated by a boiler is strongly dependent on two main attributes: the heat capture efficiency of the boiler’s convective sections, and the effectiveness of the furnace combustion system in achieving complete fuel burnout. But there’s more to the equation. Steam generation rates are also a function
