If you're generating HP steam you must have a use for it. If you have a use, you'll get condensation. That condensation flashes at a lower pressure, creating MP or LP steam. If your use for LP or MP steam is much greater than your use for HP steam, either install a smaller HP boiler for those uses and the larger boiler(s) for the LP or MP uses, or get creative and compress the MP steam to generate Hp steam (and live with the losses). Also, consider a cogen system, where Hp steam can be used where it's needed and the condensate from the turbine provides an excellent source of flash steam. This is all relatively old (20+ years) practice.

Dear friends,
As you may be all aware, Steam is one of the most widely used Heat Transfer medium used in process industries. What in your view is the most compelling problem that is facing the industry related to steam solutions? For example, someone would like to let down HP steam for further use down line for MP and LP consumers after de-superheating, but it involves a lot of energy wastage. I mean, like most of the industries are striving for better energy conservation, using pinch technology to transfer energy from the higher levels to the next lower level successively, and providing means of low temperature heat recovery and prioritizing the equipment and piping whose insulation has to be changed etc.
I also want to know views of different people in different fields who may vary from industrialists to entrepreneurs, consultants, process designers, commission engineers, piping designers and students.

Regards,

Varun Pant
