Boiler refractory

I think my post from earlier today got deleted in the transfer to the new site. Sorry if it s a duplicate post.
I am looking for a PDF or book that lists what mixes of refractory to use. Years ago I worked for a boiler company and we used Plibrico products, and the guys there seemed to just know what ratios for which areas. Just looking for something that says what to use for burner cones, target walls, patching cones, things like that so I have a reference.

Thanks!
