Validation of Pure Steam. Non-condensable gases should not be more than 3.5%. 2. Steam Dryness Value: Dry steam has more energy than the wet steam. Wet steam has water with it and does not have heat energy as dry steam. Dryness of steam is determined by the latent heat. Dryness of the pure steam should not be less than 90%.
The probability of steam generator tube failures can be reduced through timely and effective inspection, diagnosis, and appropriate acceptance (fitness-for-service) criteria. Eddy current testing has emerged as a standard procedure for inspecting thin-walled steam generator tubes because it offers high scanning speed and good accuracy. However,
Classification of Steam Boilers. The main purpose of steam boilers is to generate steam, and so the way in which the steam is generated and consumed forms the major category. The major two groups of boiler application are Industrial steam generators and power generation boilers. Boilers are also classified as fire tube and water tube boilers.
Aug 09, 2016 · A generator is attached to the rotor of the turbine and as the turbine rotates it also rotates with the speed of the turbine. The generator converts the mechanical energy of the turbine into electrical energy. After striking on the turbine the steam leaves the turbine and enters into the condenser.
Oct 26, 2014 · Basically, It is used to convert water into steam at sub-critical pressures. Steam generator: An steam generator covers the whole unit encompassing water tubes, fire box, grate superheated, air heaters and economisers etc. It is used to convert water into steam without boiling at sub-critical pressures .
The main application of the (Heat Recovery Steam Generators) HRSG is in Combined Cycle power plants. In these plants the power generation from the Rankine cycle part, ie. the steam turbine, is around one third of the total power generated . HRSG’s produce the steam for this. Classification of HRSG’s is on application, design, or operation.
Types of Solar Energy. When the sun is shining, the on-grid electric power is shut off and the water heater uses the water heated from the sun instead, saving your home energy and money. Another example of an active solar system is a photovoltaic solar panel array that is mounted on a tracking system.
Steam Turbines Classification. Type of blading: The type of blading used on the HP turbine is impulse blading because it extracts more work from the high pressure steam than reaction blading. Impulse blading is in the shape of a half moon. As steam impacts the moving blade, it pushes the blade forward.

Boiler Types and Classifications. There are two general types of boilers: ''fire-tube'' and ''water-tube''. Boilers are classified as "high-pressure" or "low-pressure" and "steam boiler" or "hot water boiler." Boilers that operate higher than 15 psig are called "high-pressure" boilers.
Oct 01, 2011 · A well-operated steam generator can save money. In a steam-driven turbine system, water is heated in the steam generator to produce high-temperature, high-pressure steam. Steam is then expanded in a turbine to produce electricity from a generator. Turbine steam is condensed back into water in the condenser. A pump then returns the water to the steam generator.

Oct 21, 2019 · A steam generator is also sometimes referred to as a boiler. The classification of the different types of boilers is generally based on configuration. For example, the Haycock or pot boiler is shaped like a kettle, and the fire-tube boiler is designed in the shape of a barrel with a connecting tube-like structure.
However, not all steam is the same. The properties of steam vary greatly depending on the pressure and temperature to which it is subject. In the article Principal Applications for Steam, we discussed several applications in which steam is used. In the sections that follow, we will discuss the types of steam used in these applications.
CLASSIFICATION OF STEAM GENERATOR TUBE DEFECTS 53 electromagnetic property of this method is described by the skin depth, which can be obtained by the solution of the simpli®ed diffusion equation and is given by: 1 d 3 2p mrel s f 10 7 1=2 where d is the electromagnetic penetration depth and f is the ECT frequency.
1. According to the working principle steam turbines are mainly divided into two categories : a)Impulse Turbine. b).Reaction Steam Turbine. ⇨When steam strikes the moving blades through nozzles called Impulse Turbine and when it strikes the moving blades under pressure via guide mechanism called Reaction Turbine.
Industrial Steam Generators 2 A long history in industrial boilers Having supplied thousands of industrial boilers, ranging in size from 10-330 tonne/hr steam capacity (1-75 MWe), and firing a wide array of solid, gaseous, liquid industrial and waste fuels, we have the expertise to solve your industrial energy needs.

Oct 27, 2017 · After the condensation of steam, the condensate is pumped to the hot well with the help of condensate extraction pump. The air extraction pump extracts the air from the condenser and creates the vacuum inside it. The vacuum created helps in the circulation of cooling water and flow of condensate downward. Classification of Steam Condenser
In the steam generator, low-temperature water is the working medium that receives the heat of combustion of fuel and becomes high-energy steam. The heat of steam is converted to mechanical energy in the steam turbine and then to electrical energy in the generator. The sequence of these activities is shown in Figure 2.1.
The condensing steam turbine is a conventional steam turbine in which the steam exiting the turbine exhaust is condensed to provide the maximum energy capture. This is the type of steam turbine that will be used in a bottoming cycle CHP plant in which waste heat or energy from an industrial process is used to raise steam to generate electricity.
Classification of Turbines – steam supply and exhaust conditions. The pressure inside condenser is given by the ambient air temperature (i.e. temperature of water in the cooling system) and by steam ejectors or vacuum pumps, which pull the gases (non-condensibles) from the surface condenser and eject them to the atmosphere.
compressor, electric generator, or propeller. Turbines are classified as hydraulic, or water, turbines, steam turbines, or gas turbines. Today turbine-powered generators produce most of the world's electrical energy. Windmills that generate electricity are known as wind turbines . Advantages
Steam turbines may be classified into different categories depending on their construction, working pressures, size and many other parameters. But there are two basic types of steam turbines: impulse turbines; reaction turbines. The main distinction is the manner in which the steam is expanded as it passes through the turbine.
