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. This is achieved by passing the exhaust steam into a condenser, which condenses the exhaust steam from the low-pressure stages of the main turbine. The condensing turbines are able to use the total energy of the inlet steam flow to a maximum extent. Therefore, this type of turbine is used for power utilities that want to supply electricity to consumers as much as possible.
The condensing turbines take high-pressure steam, expand it in turbine nozzles and blades, and exhaust it to a condenser at lower than atmospheric pressure. Condensing steam turbines are used when power must be generated with minimum steam consumption. The condensing turbines also have bleed points to satisfy steam demands at medium intermediate pressures. Condensing steam turbines are used when the bleed points to satisfy steam demand are low and pressure variations can be tolerated.
Condensing steam turbines are mainly used for power generation where bleed steam is required for feed water heating, LP heater, and deaerator requirement, and where bleed steam is utilized to meet small process demands.

Steam turbines account for more than half of the world’s electricity production in power plants around the world and will continue to be the dominant force in electricity power generation for the foreseeable future. The enhancement of steam turbine efficiency is increasingly important as the urgency to reduce CO2 emissions into the atmosphere is a problem at the forefront of power production. Increasing efficiency in steam turbines, and other components of power plants, will help meet the growing demands for electricity worldwide while reducing harmful greenhouse emissions.

Steam turbines are used in coal-fired, nuclear, geothermal, natural gas-fired, and solar thermal power plants. Also, steam turbines are increasingly needed to stabilize fluctuating power demands from solar and wind power stations as renewable energy sources grow worldwide. The current emphasis on steam turbine development is for increasing efficiency, mainly by increasing steam turbine capacity, as well as increasing operational availability, which translates to rapid start-up and shut down procedures.

The efficiency of steam turbines increases with increasing inlet temperature and inlet pressure; however, limits are imposed in the case of Small to Medium sizes steam turbines due to the limited steam flows and thus the related boiler design parameters. There are many methods to improve the thermal efficiency of a steam cycle, in the case of small to medium size steam turbines, but a balance must be reached between efficiency improvement and economical costs with each design. It is also important to consider the complexity owing to increasing steam pressure and temperature beyond a reasonable level.

Usually, it pays in terms of overall all cost-benefit if the inlet pressures and temperature are in the range of about 67 bar and 495 deg C for Steam Turbines of capacity range up to 5 MW. This is considered to be a sweat spot towards reasonable investment cost on one hand and the efficiency on other.

Certain Steam Turbine technologies are intrinsically superior in terms of efficiency compared to others. Reaction Steam Turbine technology offers better efficiency than impulse steam turbine technology. However, there are other limitations when such technology is applied to Industrial Steam turbines with varying steam flows. Hence a balance between the selection of turbine technology is very important to ensure a practical steam turbine installation in the small to medium range.

Turtle Turbines manufactures steam turbines considering all these aspects while configuring the basic steam turbine design. This has resulted in a balanced Steam Turbine design that provides the best in its class efficiency without compromising the operational challenges in Industrial Steam Turbines.

An effective way to increase energy efficiency is to recover waste heat. The process industry mainly consumes two types of energy. Fossil fuel to generate process heat and electric energy to drive motors and for use in specific process steps. Waste heat can also be used to generate steam, which can be used to drive mechanical processes or generate electricity. Hence cogeneration facilities are designed to use one energy resource to create both heat and electricity. Steam Turbines play a very important role in waste heat recovery applications. Steam Turbines are very essential to generate the power in waste heat recovery process because it generates power within 25% of the cost of the grid / utility power cost.
In the waste heat recovery process, the energy and cost-saving potential are closely linked to the flow of heat in the plant in most cases. Waste heat recovery is basically used to try to recover maximum amounts of heat in the plant and reuse it as much as possible, instead of just releasing it into the atmosphere. Waste heat recovery steam generators can be used to generate steam for district heating or factory processes or to drive a steam turbine to generate more electricity.
Turtle Turbines supplies steam turbines for Waste Heat Recovery also. For more information please visit turtleturbines.com

The modern Steam Turbine was invented in 1884 by Charles Parsons and in 1980 Carl G. P. de Laval designed a high-speed small reaction turbine that worked at about 40,000 rpm. De Laval then developed Single Stage impulse turbine that used converging-diverging nozzles. C.E.A. Rateau developed the first multistage steam turbine. At about the same time Charles Curtis developed the Velocity-compounded impulse turbine.

Cogeneration means combined heat and power (CHP). Cogeneration is defined as the sequential generation of two different forms of useful energy from a single primary energy source. It produces electricity and thermal energy at high efficiencies using a range of technologies and fuels. Cogeneration used for many years all over the globe across different industries in several forms like steam boilers and steam turbines, gas turbines, reciprocating engines, and heat recovery systems. In Cogeneration, the fuel is used first to drive the prime mover to generate electricity and produce heat. The heat is then used to boil water and generate steam. Some of the steam is used to support a process while the remaining steam is used to drive a steam turbine to generate additional power.
Cogeneration is very efficiently helpful by using waste heat recovery technology to capture wasted heat associated with electricity production. Cogeneration systems typically achieve total system efficiencies of 60 to 80%. For micro-cogeneration systems, the main output is heat, with some electricity generation, at a typical ratio of about 6.1 for domestic appliances.
In the case of steam turbines, cogeneration technologies widely commercialized include extraction and backpressure steam turbines. The capital cost to build a cogeneration plant and the size of the plant required to demand a constant load 24/7 for viability and financial advantages, but the main advantage of this type of cogeneration is the long plant life for the steam turbines due to low wear and tear. In steam cogeneration systems the fossil fuels mostly used are coal, oil, and natural gas.
Cogeneration is likely to be most attractive because the requirement of demand for both steam and power is balanced which is consistent with the range of steam. And also power output ratios that can be obtained from only suitable cogeneration. Cogeneration is also most likely to be attractive for a single plant or group of plants that has sufficient demand for steam and power to permit economies of scale to be achieved. Cogeneration also helps peaks and troughs in demand can be managed or, in the case of electricity, adequate backup supplies can be obtained from the utility company.
The ratio of heat to the power required by a site may vary during different times of the day and seasons of the year. Importing power from the grid can make up a shortfall in electrical output from the cogeneration unit and firing standby boilers can also satisfy additional heat demand.

A governor is the component of the steam turbine control system that regulates the rotational speed in response to changing load conditions. The governor output signal manipulates the position of the steam inlet valve or nozzles which in turn regulates the steam flow to the turbine. The governing of the turbine is necessary as a turbine is directly coupled to an electric generator which is required to run at a constant speed under all fluctuating load conditions
In a steam turbine, there are three types of governors are used.
Throttle Governing of Steam Turbine
Nozzle Control Governing Of Steam Turbine
Bypass Governing of Steam Turbine.
Throttle Governing of steam turbine
In this governing system, the pressure of the steam turbine is reduced at the Turbine entry thereby decreasing the availability of energy. In this method, steam is pass through the restricted passage thereby reducing its pressure across the governing valve. The flow rate is control through a partially opened steam turbine control valve. Throttle governing is used for small turbines. Its cost is less and it has a simple mechanism. In throttle governing the steam is throttled whenever the load falls below the design load to maintain turbine speed constant. In this system, a centrifugal governor is driven from the main shaft of the turbine by belt or gear arrangement. A control valve is used to control the direction of oil flow.
Nozzle control governing steam turbine
Nozzle control governing of steam turbine is basically used for part-load condition. Some sets of nozzles are grouped together and each group of the nozzle is supplied steam controlled by valves.
Bypass governing of steam turbine
The bypass line is provided for passing the steam from the first stage nozzle box into a later stage where work output increases. This bypass steam is automatically regulated by the lift of the valve which is under the control of the speed of the governor for all loads within its range.
