Selective Catalytic Reduction (SCR) For Boilers - …

Selective catalytic reduction considerations. There are some factors that must be considered before installing an SCR system. Firstly, the SCR systems function best at higher temperatures - 400°F and above. Keeping this in mind, the specific catalyst manufacturer will determine the desired range. Secondly, watertube boilers are better suited

design superheater of steam boiler

The Steam Superheater is a coil type heat exchanger which is used to produce superheated steam or to convert the wet steam to dry steam, generated by a boiler. It is different from a boiler in a way that, boiler utilizes both sensible heat as well as latent heat to convert water into steam while superheater utilizes only sensible heat to superheat the steam in order to increase its enthalpy.

Boiler | Djoemono's Blog

The steam piping (with steam flowing through it) is directed through the flue gas path in the boiler furnace. This area typically is between 1,300 °C (2,372 °F )-1,600 °C (2,912 °F). Some superheaters are radiant type (absorb heat by radiation), others are convection type (absorb heat via a fluid i.e. gas) and some are a combination of the two.
