Help with creating superheated steam
(OP)
Hi,
I'm working on gasifier project and I am looking for help to create superheated steam to use as gasifying agent in order to increase the calorific value of the syngas. We intend to use a waste heat economizer generated by a diesel generator to turn water into saturated steam. And from there we need to superheat the steam up to 800 degrees celcius and fed to the gasifier at a flow rate of 40 kg/hr. Can anyone provide recommendations as to how to design a superheater element? Amd also, whats the best way to power the superheater element, by electricity or oil/gas?

I am sure you could use oil or gas, but I have not done that.

These electric steam superheaters are commercially available, although the one shown does not go up to 800C, some fancy materials will be needed for that temperature.....

A good reference is Steam: It's Generation and Use, by Babcock and Wilcox.

For your case, my idea is : first get saturated steam, after seperator, precede superheating upto 800 degree.
The key is control pressure and right steel tube.
Normally you need T91.
