exhaust steam turbine

This test was applied to a supercritical, once-reheated, single-shaft, three-cylinder, four-exhaust, condensing 600MW steam turbine. The condenser is a double back pressure, double shell, single flow, surface type condenser. The steam turbine rated main steam temperature is 566°C, and the rated main steam pressure is 24.2MPa.

The turbine exhaust steam is supplied to the process, and the electric output depends on the demand for the process steam. These turbines also can be used as top turbines to supply exhaust steam to existing units; this improves the entire plant''s thermal efficiency. Figure 3-24. Back pressure turbines. [3-4]

Exhaust Steam Conditions: If the steam leaves the turbine at a high energy state, that energy is wasted. Therefore, improving the condenser pressure and ensuring efficient exhaust steam flow is crucial. Operational Practices: Proper maintenance and operation of the turbine ensure minimal energy losses due to wearing of parts,

Industrial steam turbine. The SST-400 is a single casing steam turbine, providing geared or direct drive to 50 and 60 Hz generators, or to compressors and pumps. The symmetrical casing with horizontal joint flange enables the SST-400 to accept short start-up times and rapid load changes. The modular package design allows a wide variety of

For a steam turbine, a pump sends water into a boiler, which produces steam by utilizing the heat from coal or other fuel combustion. Renewable thermal energy sources can also be the source of steam. Moreover, in a combined cycle setup, the exhaust air from a gas turbine heats up water in the boiler to obtain steam.

The steam turbine is a turbine in which the potential energy of heated and compressed steam produced in a special device, a steam generator, or steam of natural origin (for example, from geothermal

While noncondensing turbines exhaust steam at or above atmospheric pressure, condensing turbines can condense at pressures of 90 to 100 kilopascals (13 to 14.5

Exhaust hoods are primarily designed to limit the pressure loss and exit energy loss of the steam over the last stage. Any pressure loss at this section of the turbine would noticeably decrease the turbine''s thermal efficiency. An ideal exhaust hood should be designed with the largest possible axial size and incorporate smooth turns to

For improving the static pressure recovery coefficient of a low pressure exhaust hood of steam turbine, this paper uses the efficient and effective Bayesian

A new heat supply strategy for the CO 2 capture process based on the heat recovery from turbine exhaust steam was proposed and evaluated. A water-steam cycle, a CO 2 capture unit, a CO 2 compression unit, and an enhanced two-stage heat pump were simulated for a 600 MW coal-fired power plant using Aspen Plus. Effects of the

Enthalpy of steam at the turbine exhaust: Hg (50 psig) (64.7 psia) 1,113 Btu/lb. enthalpy isentropic, and 1,158 Btu/lb. actual Isentropic turbine efficiency, taking into account steam leakage and mechanical losses: e ≈ 47.3% Figure 3: Steam turbine calculator

Condensing steam turbines are most commonly found in thermal power plants. In a condensing steam turbine, the maximum amount of energy is extracted from the steam because there is a very high enthalpy difference between the initial (e.g.,, 6MPa; 275°C; x = 1) and final (e.g.,, 0.008MPa; 41.5°C; x = 0.9) conditions of steam.This is achieved by

In the topping turbine, the exhaust steam is used in low-pressure and medium-pressure condensing turbines. The topping turbine work under higher initial steam temperature

This turbine uses not only fresh steam from the boiler, but also exhaust steam from hammers, presses, pump, air blower and compressor drives. A backpressure turbine is shown in Figure 1e . There is no condenser in such a turbine unit.

The nozzles and diaphragms in a turbine are designed to direct the steam flow into well-formed, high-speed jets as the steam expands from inlet to exhaust pressure. These jets strike moving rows of blades mounted on the rotor. The blades convert the kinetic energy of the steam into the rotation energy of the shaft.

1. Introduction Wetness fraction of exhaust steam from low pressure cylinders (LPC) is an important parameter closely related to the economy and safety of steam turbines (Wang et al., 2002), because the occurrence of condensation phenomena in wet steam two-phase flow would reduce the steam turbine efficiency, result in

Exhaust conditions—steam turbines either exhaust to a pressure above or below atmospheric pressure. If above atmospheric pressure, the steam turbine is known as a

Backpressure steam turbines (BPSTs) produce low-pressure (LP) exhaust steam that can be used for one or more process heating duties ( Figure 1a ). The objectives are to provide the process

Steam enters from the left through the gray pipe at the top, arriving in the very middle of the turbine and just above it. Then it simultaneously flows in both directions (to the left and the right) through the low-pressure reaction turbine, which drives the electricity generator on the right. Sponsored links.

Exhaust pressure at the exit of the last-stage blades is one of the most important parameters that limit the operation of a steam turbine, especially on days with hot ambient conditions. The main concern in these off-design high-exhaust pressure operating conditions is that it can result in flow separation, which can lead to aeromechanics

The turbines extract steam from the middle stage of condensing turbine after adjusting pressure by the control valve and utilize steam and exhaust steam as utility steam for works and others. (1)When a large amount of utility steam of one or more types is required, (2)When the power demand is less than the amount of utility steam.

These steam turbines exhaust directly to one or more condensers that maintain vacuum conditions at the discharge of the steam turbine. An array of tubes with cooling water

Industrial and aeroderivative gas turbines use exhaust systems for flow diffusion and pressure recovery. The downstream balance-of-plant systems such as heat recovery steam generators or selective catalytic systems require, in general, a steady, uniform flow out of the exhaust system. One detrimental effect of having these

Back-pressure turbines expand the live steam supplied by the boiler to the pressure at which the steam is required for the process. The exhaust pressure is controlled by a regulating valve to suit the needs of the process steam pressure. Back-pressure turbines are commonly found at refineries, district heating units, pulp and

Decreasing the turbine exhaust pressure significantly increases the specific volume of exhausted steam, which requires huge blades in last rows of low-pressure stage of the steam turbine. In a typical wet steam turbines, the exhausted steam condenses in the condenser and it is at a pressure well below atmospheric

Steam Turbine Exhaust Size Selection The steam leaving the last stage of a condens-ing steam turbine can carry considerably useful power to the condenser as kinetic energy. The turbine designer needs to select an exhaust area

A steam turbine is a rotating machine that converts the energy of the steam (by virtue of its pressure and temperature) into the mechanical energy of the rotor. For this purpose, the

Steam turbine efficiency is a measure of how well a turbine can convert the energy from steam into useful work. This efficiency is typically expressed as a percentage, indicating the ratio of the turbine''s mechanical power output to the thermal energy input from the steam. High efficiency in a steam turbine means that less energy
