We have a 15-M Keystone (O) Type package boiler made by ERIE CITY IRON WORKS. Its steaming rate is approx 60,000~70,000lb/hr. Its flue gas temperature is approx. 570 degree F.(assumed) The fuel is natural gas. We use it as a back-up and it is not operated frequenty. Our goal is to reduce its NOx level.
I received two options. One is to install a low NOx burner with new FD fan and control system, like Rapid Mix Burner (RMB). The other one is to use Selective Catalytic Reduction (SCR). We installed RMB at somewhere else before and it worked. SCR is new to us and we are not familiar with it. But SCR seems to be cheaper and easier to install.
I wonder if you can give me some suggestions about the PROs and CONs of each option.
Thank you in advance for your opinions.
