Boiler with two stages - Unmet Hours

I have a boiler with two stages that has no gas rate modulation besides off and those two stages. What is the proper method to model this? Is the appropriate setting "SequentialLoad" for the Load Distribution Scheme at the "Supply Equipment / Demand Equipment" boundary? I tried that and "Optimal", but got the same water heating energy usage results either way.

Optimization of the three-stage biomass gasification

Oct 09, 2019 · First, the wood is heated and moisture in the wood begins to evaporate. At this point any heat produced goes to further evaporate moisture. The second stage begins when temperatures reach about 500°F. Here, wood starts to break down chemically and volatile matter is vaporized. These vapors contain between 50%-60% of the energy in wood 8. Temperatures in excess of 1100°F mark the third …
