kk, Have asked before and got a definite not worth the trouble ...but..
i got this vision of a single col with plate disabling to boiler or return to next plate rather than F'ing about with modular sections with a couple of plates in it
Does a 4 plater make a distinct diferent drop to a 6 plater with 2 plates feeding back... Should the return be to the next lower plate or back to boiler Thoughts?
Also this crow & EG volcanic rock section which I'm defintely going to do...reckon best just under product deph i.e. above plates as distinct from "drowning" it at the base of the col?
So fair game...open up the thinking and fire a post back...
