This will vary from Boiler manufacturer to manufacturer. It can be 12 sft to 18 sft/lb steam for a water tube boiler and 6.9 to 10 sft/lb steam for a fire tube boiler.
I do not understand why you are asking this and wood consumption/100 Tph steam Boiler. It seems obvious that you are taking a Superheated wood-fired fludized-bed Power Boiler for a 15 mw to 20 Mw Steam Turbine. You should be getting all details from your EPC Supplier. Please read first what he has sent before starting to ask these from us.
