Hi every one

Is there any rule of thumb for rough estimation of amount of steam which is possible to generate by using HRSG in fired heaters? based on duty of fired heaters?

Fired heaters usually are built with a convection section. The usual solution to increasing heater efficiency is to add an air preheater.

thanks but I don't want to increase efficiency, we have shortage of steam generation, and we have two fired heater which have no convection section.

Since these heaters are in service, you can calculate the amount of steam that you can generate. You should always look for opportunities to save money.
