Extraction Back Pressure Steam turbines are used when steam at two different process pressures is required. In Extraction Back Pressure Steam Turbines the required Steam for the process at required pressures is supplied through Extraction openings and turbine exhaust while generating power in the process.
Electric output is dependent on the demand for process steam. If required double or multiple steam extraction at different temperatures and pressures for plant processes can be supplied through extraction openings, however, such turbines are complex and rarely used. An Extraction Back Pressure turbine has opened in its casing for extraction of steam at the desired pressure. The extracted steam may be used for process purposes. Automatically regulated depends on the steam turbine design. Regulated Extraction allows for better steam flow adjustments through the steam turbine to generate additional mechanical power depending on the operating system. In special applications of special steam turbines, several Extraction points may be included, each at a different pressure corresponding to a different temperature at which heating service is needed in a plant. However such turbines are very complex and are normally not used. Specific needs for steam and power over time determines the extent of steam extraction. In large plants, additional steam may be admitted to the steam turbine. This happens when multiple boilers and steam generation systems are used at different Pressures because of the plant’s complexity and the need to reach thermal efficiency.
Extraction Back Pressure Steam turbines are used in refineries, district heating units, and pulp, and paper industries where large amounts of low-pressure process steam are needed. The electrical power generated by extraction back pressure turbines is directly proportional to the amount of process Steam required.

Blades are the heart of a steam turbine, as they are the principal elements that convert thermal energy into kinetic energy. The efficiency and reliability of a turbine depend on the proper design of the blades and its design factors. The blade design is a multi-disciplinary task. It involves the thermodynamic, aerodynamic, mechanical, and material science disciplines. Total development of a new blade is, therefore, possible only when experts in all these fields come together as a team.
One of the key factors influencing the efficiency of turbines is the design of the turbine blades. Almost all the blading used in modern mechanical drive steam turbines is either of drawn or milled type construction. Drawn blades are machined from extruded airfoil-shaped pieces of material stock, while milled blades are machined from a rectangular piece of bar stock.
The efficiency of the turbine depends on the following blade parameters :
1) Inlet and outlet angle of the blade.
2) Blade materials.
3) Profile of the blade.
4) Surface finishing of the blade.

The modern design of turbine blades maximizes efficiency through complicated surface geometries. Machining these surfaces, therefore, requires a careful machining strategy. Well-worked machining strategy with continuous improvement is crucial to productivity and subsequent processes. Innovative tooling and qualified applications are the only way to meet the challenges involved especially the rotating blades. Semi-finishing and finishing of the blades also require the best tool and method solutions to achieve quality at high efficiency.
An improved blade design focused on resisting the effects of stresses, corrosive agents, and creeping inducing temperatures will elevate the turbine efficiency, consequently leading to an increase in the power plan’s overall efficiency. Improving efficient blade design will serve to reduce operating costs even further and lessen the environmental impacts of steam turbines. Overall, such a combination of technologies would benefit society by providing an efficient, viable, and sustainable means of generating electrical energy.

Back Pressure Turbine :

A Back Pressure Steam Turbine is utilized in industrial applications which require low or medium pressure steam for process heating. When high-pressure steam enters a back-pressure steam turbine, some of its thermal energy is turned into mechanical energy when the steam expands.
The mechanical energy is utilized to power an electric generator or mechanical equipment like pumps, fans, and compressors, among other things. The needed pressure outlet steam leaves the back pressure steam turbine, and the steam flows to the plant for process steam applications such as heating or drying.

Condensing Steam Turbines :

The steam expands below atmospheric pressure within a condensing turbine and then “condenses” while heating the cooling water in a condenser. The power plant is an ideal application for Condensing Turbines. The primary goal is to generate electricity using steam.
The pressure of steam after it exits the outlet of the condensing turbine is usually under a vacuum. The Condensate is returned to the Boiler for generation of steam. Thus the cycle continues. Condensing Turbines are used in industries with Waste Heat Recovery Boilers or the factory intends to generate its own power for various reasons.

Manufacturers have categorized steam turbines by a different variety of flexible design features. They set them up in a configuration optimized for special process requirements. This keeps delivery time and cost at a minimum level. They combine proven technology with convincing operating reliability.
Most of the common features which lie under every manufacturer for the steam turbine, they should be compact, powerful, efficient, reliable turbine and capable of meeting a wide range of steam cycles, site conditions, and operating modes. Frequent power cuts, blackouts, and load shedding have contributed to the increased demand for steam turbines for power generation.
Steam turbine manufacturers consider and apply in the fields such as Power Generation, Cogeneration, Waste-Heat Utilization, Pressure-Difference Utilization, Waste-to-Energy Generation, Biomass Power Generation, and Industrial Driving.

The heat and Mass Balance Diagram (HMBD) is the graphical representation of the heat and mass balance of a steam turbine-based power plant system. The use of HMBD is for knowing steam quantity during a power cycle, Turbine power output, sizing of the de-superheater, and quantity of steam going into the process. Usually, HMBD is prepared and submitted by a Steam Turbine Manufacturer and sometimes by a boiler manufacturer too.

In the case of a Back Pressure Steam Turbine, if the steam at the inlet of the Turbine is superheated then the quality of steam getting at the outlet of a Steam Turbine is also usually superheated. On the other hand, the steam quality required in the process is dry and saturated. So HMBD always helps in deciding the quantity of spray water required in the de-superheater to supply saturated steam to the process at the desired rate. In the case of Condensing Steam Turbines, HMBD plays a vital role in sizing the Boiler and Vacuum Condenser, besides other system design parameters.

By using HMBD the deaerator steam and water quantity, condensate return quantity, and make-up water quantity can be easily mapped.

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.
