This topic interests me. Steam is a tricky thing in my opinion.
I’m currently using strong steel boilers and burning boxes as they work well together. From memory the burning box produces something like 384HU/t and the boiler receives 384HU/t which produces 192 Steam/t at a constant safe rate. the boiler self regulates by choking on ash so I don’t need to keep as much of an eye on it.
From there I use the right sized piping and valves to regulate the steam going into a machine. What piping are you using Laurynasi?
