Not every manufacturer is clear on this. Unlike the PF boiler / AFBC boiler / stoker-fired boilers/gas or oil-fired boilers, CFBC furnace panels demand stringent quality levels during manufacture & during fieldwork. Manually welded panels are not acceptable. Only panels made by automatic welding machines are to be used.
