Industrial Combustion Boilers - IEA-ETS

2015-7-31 · water-tube boilers, tubes containing water are heated by combustion gases that flow outside the tubes, while in the fire-tube boilers hot combustion gases flow inside the tubes and water flows outside. Key design parameters to determine the boiler size and power are the output steam mass flow rate, pressure and temperature.

Velocity at exit of boiler (cylinder) - Mechanica

If the boiler is producing steam at 200C then the pressure can be read off the steam tables. If the boiler was producing at a lower pressure then the temperature would be lower. From your description, it seems fair to assume the steam is saturated at the boiler. Then you need to know the mass flow rate of the steam to the pump (driver?).
