If you know of a better burner option for these HB's let me know. I know keith appleton uses blowtorch nozzles.  I feel if I got the heat source better, it might be able to run it.

I am not really familiar with that boiler line, though suspect that specific model to be a bit small for that engine. In general, from an engineering standpoint you are looking at an approximate equation like:


                Boiler water capacity
            _____________________________                                        =/>  Swept Cylinder Volume @ speed + System Steam/Temperature Volume Loss
Flue heating surface area x (BTU input - BTU system heat loss)

Or to say it in plain language:

(the Water Capacity of the boiler) divided by (the flue heating surface area) times (the BTU input minus the BTU system heat loss) must be equal to or greater than (the Swept Cylinder Volume at desired speed + Volume of System Steam/Temperature Loss)
