A steam turbine generator works by heating water to extremely high temperatures until it is converted into steam, then the steam energy is used to rotate the blades of a turbine to create mechanical or rotational energy.. This rotational energy caused by the high pressured steam turbine is used to generate electricity from an attached generator.

At steam extraction and admission locations, steam flow control valves usually add to the steam and control system cost. When the steam is expanded through a high-pressure ratio, as in large steam turbines, the steam can begin to condense in the turbine when the temperature of the steam drops below the saturation temperature at that pressure.

This process can be followed on an enthalpy-entropy (H-S) diagram, known as a Mollier chart. In the example diagram (), the path from Point 1 to Point 2 represents typical BPST operation at a chemical plant, pulp and paper mill, oil refinery, or food processing facility; superheated 600-psig steam at 700°F (Point 1) expands as it passes through the turbine and is exhausted at a …

tubes and as it heats, steam begins to form. The ascending force of this steam produced during the boiling causes liquid and vapors to flow upwards in parallel flow. At the same time the production of vapor increases and the product is pressed as a thin film on the walls of the tubes, and the liquid rises upwards. Fig.2. Rising Film Evaporator

Tank volume 5100 cubic feet. Fill time 45 minutes. Use a #2 Figure 402, 4X Blower. Unit will handle 1050 cfm at 20 inch water draft, using 1600 pph steam at 125 psi.

turbine - turbine - Steam turbines: A steam turbine consists of a rotor resting on bearings and enclosed in a cylindrical casing. The rotor is turned by steam impinging against attached vanes or blades on which it exerts a force in the tangential direction. Thus a steam turbine could be viewed as a complex series of windmill-like arrangements, all assembled on the same shaft.

The recovery boiler is an integral part of the steam and power balance at the mill. The economic viability of the mill depends critically on efficient and reliable recovery boiler operation. ... with various arrangements of steam flow vs. gas flow. Low temperature superheaters may use a counterflow between steam and flue gas. Higher temperature

ICE EFFECTS ON STREAMFLOW -- During cold weather, stage and discharge values may be affected by ice at some streamgages. Streamgages experiencing ice conditions will have the discharge record temporarily disabled to prevent the display of erroneous discharge values. Display of discharge record will resume when it is determined that ice ...

If steam is extracted from the turbine at a pressure of 500 psia, energy/mass balance calculations show that the flow rate to the heater should be 20.8 percent of the total steam flow. The ...

• Monitor steam flow rate, mill O 2 & mill press • Use wet O 2 analyzer for test. Inerting Modes • Normal startup – Mill is clean when started • Normal shutdown • Post trip recovery – Mill is dirty when tripped – May proceed to shutdown, OR – May proceed to restart.

Steam flow costs range from $4.00 to $12.00 per 1,000 PPH, so the average cost is approximately $8.00 per 1,000 PPH steam flow. If, for example, a large Fourdrinier steam-box uses 30,000 PPH, it costs the mill $240 per hour to raise the sheet temperature at the average cost of steam of $8 per 1,000 PPH.

SST-500. The SST-500 is a single casing, double exhaust flow steam turbine, which can be used as an entire drive or as the lowpressure module of a multiple-casing turboset, directly driven or geared. This turbine, with its capacity to operate over a wide range of speed and power, is ideal for large steam volume flows.

Any type of sterilisers can be used provided the Mill design such as Boiler and size of sterilisers match the steam flow and pressure from the Steam Turbine. Vertical Sterilisers had problems but improvement in the steam flow and pressure has resulted in best efficiency for mill throughput of upto 30tons/hr operations.

In fluid velocity method, the steam velocity is assumed and the line size is calculated for the required flow-rates by the following formula: Q = A x v . Where, Q = Volumetric flow-rate (m3/s) = (Steam Flow in Kg/hr * Specific Volume M3/kg) / 3600 . A = cross-sectional area of a pipe formula (m2) = D24 . v = steam velocity (m/s)

The steam in down flow condenser flows perpendicular to the direction of flow of cooling water, so it is also called as cross-surface condenser. (ii) Central Flow. In central flow condenser, the steam enters at the top of the condenser and flows in downward direction. In this the suction pipe of the air extraction pump is provided in the center ...

Where saturated steam must be used, separators are often installed in the supply piping to remove entrained condensate from the steam flow. Besides power generation, other typical propulsion/drive applications are usually for either turbine-driven compressors or pumps, ex. gas compressors, cooling tower pumps, etc.

Step 1: Determine Inlet Properties. Using the Steam Property Calculator, properties are determined using Inlet Pressure and the selected second parameter (Temperature, Specific Enthalpy, Specific Entropy, or Quality). The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow:

The steam flow rate is optional in the range of 15~40 m/s. It is recommended to select the flow rate of 25 m/s. Too big a pipe diameter will increase the installation cost, the thermal loss during conveying and the condensate generated, resulting in requiring more drainage devices or reinforcing the condensate draining capacity.
