Superheated Steam - an overview | ScienceDirect Topics

Aug 02, 1970 · Superheated steam is steam heated to a temperature higher than its boiling point corresponding to the operating pressure. Figure 3 shows the schematic diagram of basic principle of a closed system superheated drying system. Saturated steam (100 °C, 1 bar) after heated to a superheated state at 110 °C, gaining 30 kJ kg −1 of energy, if it is used as a drying medium, absorbs moisture from

Boiler explosion - Wikipedia

A boiler explosion is a catastrophic failure of a boiler.There are two types of boiler explosions. One type is a failure of the pressure parts of the steam and water sides. There can be many different causes, such as failure of the safety valve, corrosion of critical parts of the boiler, or low water level. Corrosion along the edges of lap joints was a common cause of early boiler explosions.

Safety valve - Wikipedia

The first safety valve was invented by Denis Papin for his steam digester, an early pressure cooker rather than an engine. A weight acting through a lever held down a circular plug valve in the steam vessel. By using a "steelyard" lever a smaller weight was required, also the pressure could easily be regulated by sliding the same weight back and forth along the lever arm.

Fire Tube Boiler | Operation and Types of Fire Tube Boiler

Feb 24, 2012 · Fire tube boiler is one of the most basic types of boiler and the design is also very old. It was popular in 18 th century. It was mainly used for steam locomotive engines. Operation of Fire Tube Boiler. Operation of fire tube boiler is as simple as its construction. In fire tube boiler, the fuel is burnt inside a furnace.The hot gases produced in the furnace then passes through the fire tubes.

Steam generator (boiler) - Wikipedia

A steam generator is a form of low water-content boiler, similar to a flash steam boiler. The usual construction is as a spiral coil of water-tube, arranged as a single, or monotube, coil. Circulation is once-through and pumped under pressure, as a forced-circulation boiler.

Thermal Power Generation Plant or Thermal Power Station

May 24, 2014 · The theory of thermal power stations or the working of the thermal power stations is very simple. A power generation plant mainly consists of alternator runs with help of a steam turbine. The steam is obtained from high-pressure boilers. Generally in India, bituminous coal, brown coal, and peat are used as fuel for the boiler.The bituminous coal is used as boiler fuel has volatile matter from

Boiler Feed Water Pump Working Principle and Operation

Jul 18, 2018 · Boiler feed water pumps are commonly centrifugal pumps. To ensure a high enough head and pressure, Boiler feed Pumps have been arranged in series (multistage pumps). A feedwater pump is most often driven by an electric motor for energy efficiency. Often two steam turbine-driven (turbo pump) and two electric feedwater pumps are used.

Spirax Sarco Steam Traps - M&M Control

Spirax Sarco inverted bucket steam traps employ a simple and well-proven principle, which relies on the difference in density between steam (a vapor) and condensate (a liquid). They have a robust design and incorporate a simple density sensitive bucket and lever mechanism.

How to run a hot-water zone off a steam boiler

Jun 18, 2014 · The boiling point of water increases as the pressure on top of the water increases. For instance, if your steam boiler operates at 2 psig pressure, the water in the boiler will boil at 219 degrees F. If you run the boiler pressure up to 5 psig, the water won't turn to steam
