Hello, I am new here. I am trying to put together a plan for building a large prefurnace for a boiler. Is there any expertise here with these things?
I am working on the plans for a sloped grate rectangular prefurnace with primary under grate air and secondary air entering with the hot gases at the point of entry into the boiler vessel.
I am most curious about the ash and its removal. Currently I have the ash collecting in a trough at the base of the sloped grate with a small auger to drive it to one side. The whole affair is sealed off and would require the blowers to be powered down to remove the collected ash.
Also what type of steel would best suit as a grate or should I be going with a refractory grate?
