4. Boiler Feed Pump: It is a pump installed in between the hot well and boiler. It pumps the feed water from the hot well to the boiler. And this is done by increasing the pressure of condensate above boiler pressure. 5. Air Extraction Pump: It is a pump used to extracts or removes the air from the steam condenser. 6.
A power plant is an industrial facility for the generation of electric power. In this article, one will get detailed information about Boiler Water Chemistry & Steam Generation System in Power Plant, types of boiler, advantages & disadvantages of fire tube boiler, and Internal Boiler fitting Valves, and Accessories.
An electric hot water or steam boiler may be the right selection. Vapor Power can customize equipment to meet a customer's exact needs. Steam generators are available from 15 psig design pressure to 3200 psig and even supercritical design pressures, so we have equipment for every application.
It is important that dry steam is used for power generation because water droplets could damage the power-generating turbines. Supercritical Steam Generation - Another process often used in the production of electricity is subcritical steam generation. Standard boilers function at subcritical levels, defined as less than 3,200 psi.
Thermal power plant or thermal power station is the place where we use the energy of heat to produce electric power, and it's the most convenient sources of electric power generation, as we burn fuels such as oil, coal or liquefied natural gas to produce high temperature, high-pressure steam then we use this steam to turn a steam turbine
Water directly becomes steam. This is the Critical Pressure and the Critical Temperature. For steam this occurs at 374 deg C and 220.6 bar. Conventional steam power plants operate at a steam pressures in the range of 170 bar. These are Subcritical power plants. The new generation of power plants operate at pressures higher than the critical

Only a brief description and salient features of the items covered are added. For ease of understanding, typical schematic diagrams are also
This is the pump for sending high pressure and high temperature fluid to the boiler. The types vary depending upon the pressure. The single casing type is used for the combined cycle, the subcritical steam power generation, etc.
lp,hp feedwater heaters in thermal power plants shivaji choudhury FEEDWATER HEATERS: FEEDWATER HEATERS A feedwater heater is a power plant component used to pre-heat water delivered to a steam generating boiler In a steam power plant (usually modeled as a Rankine cycle), feedwater heaters allow the feedwater to be brought up to the saturation
The way energy from fuel gets transformed into electricity forms the working of a power plant. In a thermal power plant a steam turbine is rotated with help of high pressure and high temperature steam and this rotation is transferred to a generator to produce electricity. Steam turbine is the heart of the power plant.
Best Practice Guidelines for Boiler Soot Blowing. Utilities have been cleaning their boilers for many years using either steam or high-pressure air. In the past, when air was used, due to the size of the boilers and the reasonable quality of fuel used, a relatively small amount of cleaning was required.
The pressure in the boiler of a steam power plant operating on the ideal Rankine cycle is 1250 psia. The condenser pressue is 2 psia. The mass flow rate of steam through the system is 75 lbm/s and the quality of the steam at the turbine exit is 0.9.
3. Increasing the boiler pressure. The effect of increasing the boiler pressure on the Rankine cycle efficiency is illustrated on a T-s diagram on the left. If the operating pressure of the boiler is increased, (process 2-3 to process 2'-3'), then the boiling temperature of the steam raises automatically.
Use btu/hr (British thermal units/hour) heat input rate to calculate boiler steam flow. It takes 970.28 btu/hr to produce 1 pound of steam at the above conditions. If 50 million btu/hr are being applied to the boiler, divide by the 970.28-btu/lb to yield 51,531-lb/hr steam flow. This is an average industrial boiler.

Silica needs to be controlled at DM plant also. The percentage of impurity allowed in boiler water/steam is function of boiler operating pressure, so, more critical for high pressure boilers. Two basic ways to regulate corrosion in water, are All Volatile Treatment (AVT) and Oxygenated Treatment (OT).
When Thomas Edison built the world's first central power plant on Pearl Street in downtown Manhattan in 1892. The first steam-turbine generator, which started operating just two years after Pearl Street Station, converted only a measly 1.6 percent of heat from coal into electricity. In modern terms, this was a laughably inefficient machine.
