Don’t waste your time on this project. The design of a coal burning boiler is optimized for the type of coal fired. A biomass boiler burns a very different type of fuel with a considerably lower heating value and high and very variable moisture content.
Biomass can also produces extreme...
The idea to store temporarily unsellable wind power in an elevated lake is sound but 200 feet is a little low for a PHES plant.
The important formula is; power [kW] = flow[m3/sec]*head[m]*9
Example; 100MW = 55.5m/sec. * 200M * 9
It is as simple as that.
