Superheated Steam Boiler Function

What is Superheated Steam - Definition

The steam superheat temperature is controlled by adjusting the quantity of water sprayed into the steam following the super heater. This water is supplied by the boiler feed water pumps as pressures in excess of 3,000 psi so that it can be injected into the steam header. When the steam temperature is high, the injection of water reduces the temperature and produces an increased volume of steam available to turn the turbine and produce electricity. If the steam passes through the turbine at the high temperature, no additional electricity is produced and the excess energy that was contained in the superheated steam is lost to the condenser circuit. In addition, it is not desirable to subject the turbine to excessive swings in steam …

Steam Boiler. Heat Recovery Steam Generator (HRSG) consists of several components such as superheater, evaporator and economizer which each component has different functions. HRSG components can be seen as following below: Superheater. Superheater is one of HRSG components that serves to raise temperature of saturated steam to be superheated steam.

Drying Steps under Superheated Steam: A Review and Modeling

Lancashire Boiler is a horizontal type and stationary fire tube boiler. This boiler was invented in the year 1844, by William Fairbairn. This is an internally fired boiler because the furnace uses to present inside the boiler. This boiler generates low-pressure steam and it is a natural circulation boiler.

Fuzzy Control of Boiler Superheated Steam Temperature

The temperature of the heavy fuel oil is very often 130°C to 150°C and water introduced to that temperature would immediately evaporate into steam; well it depends on the pressure too. When water is boiling it expands about 1600 times. The situation might be dangerous since the safety valves are not designed for steam.

Superheated steam has a lower density, so lowering the temperature does not revert it back to its original liquid state. Dropping the temperature of saturated steam, however, will revert it back to its old form of water droplets. Superheated steam has more energy and can work harder than saturated steam, but the heat content is much less useful.

Learn How Is Boiler Steam Used for Turbine Power Generation

The Steam Superheater is a coil type heat exchanger which is used to produce superheated steam or to convert the wet steam to dry steam, generated by a boiler. It is different from a boiler in a way that, boiler utilizes both sensible heat as well as latent heat to convert water into steam while superheater utilizes only sensible heat to superheat the steam in order to increase its enthalpy.
