    Basics Of An Industrial Steam Boiler System | Miura America

    For most applications, a water-tube boiler is far more efficient because it produces steam in minutes and requires far less time to power up and blowdown. Water-tube boilers are also usually more compact, require far less fuel to operate, and can be configured modularly to power on and off according to demand. Natural Gas vs. Dual Fuel

      Mar 04, 2020 · Larger heating surface can be achieved by using more numbers of water tubes. Due to convectional flow, movement of water is much faster than that of fire tube boiler, hence rate of heat transfer is high which results into higher efficiency. Very high pressure in order of 140 kg/cm 2 can be obtained smoothly.

      Why do we use superheated steam for a steam turbine rather

      Jul 24, 2017 · Superheated steam is mainly used to increase the steam enthalpy at turbine inlet. More the enthalpy difference across the inlet and outlet of a steam turbine, more will be power output. Enthalpy of saturated steam is increased by heating it above its saturated point and making it superheated.

      Jul 19, 2019 · Generally, Power plants require steam for the purpose of heating. Hence, this purpose is fulfilled by the boiler, where the steam is produced by boiling water. Basically, the steam is produced by boiling water beyond its boiling point where it changes its state from liquid to vapor and this vapor is known as steam.
