New Source Performance Standards, Subpart Db …

----- To provide the additional heat needed to superheat the steam recovered from the boiler steam drum, a superheater is installed in the upper section of the boiler. In this area of the boiler, flue gas temperatures generally exceed 1,100 °C (2,000 °F) . The superheater transfers this thermal energy to the steam, superheating it.

An overview of problems and solutions for …

This system consists of tubes, i.e. the heat pipes, and convection heat transfer chamber which is finally connected to the boiler chamber. Steam is generated when the hot flue gases flow outside the pipe due to convection. These hot gases transfer their heat to the water present in the tubes and come out with a lower temperature [24,25,26].

Control of in-bed agglomeration by fuel blending in a

Without direct heat extraction from the bed, adequate temperature control by air cooling alone was infeasible. Temperature control in the reactor was therefore limited by the shell heat transfer and the interaction of increased air flow, higher burning rates, and higher entrainment rates of particles.
