Small generation.
electrical power turbine
Our company has the ability to deliver, carry out installation, start-up and adjustment in the complex of steam turbine and auxiliary equipment.
The power range of manufactured steam turbines: from 250 kW to 10 MW.
Key objectives:
Cost cutting by reducing consumption from the energy network company.
Creation of back-up/main power source for stabilization the electric supply to consumer.
Creation of mobile platform for the rapid restoration of supply in case of impossibility of quick supply networks repair (natural disasters, difficult access/ remote areas, large network failure, storms, earthquakes consequences, etc.).
Formation of fireproof generation in close proximity to objects with high requirements in the aria.
The compact dimensions of the turbine installation (from 1.5h0.8 to 3.2h1.5 m) allow installing it into existing facilities and place set of equipment on the mobile chassis platform.
Application of the modern shaft seal without lubrication oil system being used makes turbine fireproof.
Turbine blades is the most difficult and expensive in making unit. Accuracy in manufacturing, compliance with all heat-treatment regulations and control at all stages is very impotent. We use only the highest quality components, resulting in significant improvement of the reliability and survivability of products.
Automation – developed, tested and applied in operating units. According to the customer's specifications adapted for specific purposes.
Utilized fields of application:
- Own small generation from the steam generator of boiler station, reducing consumption from the network company.
- Own small generation from the recovery boiler, supplying objects located remotely. Can work as a backup source of electricity.
Perspective fields of implementation:
- The application of steam-turbine plant (STP) in the existing boiler stations is of immediate interest that everything is ready: the building, boilers, heat networks. It is necessary to install STP, if there is an opportunity for the steam rate and parameters, because in most steam stations produced steam has higher parameters than that required for production. Therefore, pressure-reducing and desuperheating station (PRDS) installed parallel to STP, thereby providing boiling station and production operations with electrical energy, as well as having an independent energy security when network turned off.
- Application of STP as an adjustable turbine drive pumps, exhausters, etc. It is the cheapest drive, expensive generator is not required. Simplified automation system.
- Application of STP in the construction of new boiler stations is especially important while developing new areas of the north, since there is no need in pulling the power transmission lines, which requires large financial investments in the construction and operation, and provides large transmission losses and the heat is not transmitted over long distances.
- Application in the residential, agricultural, construction, extractive sectors. Mini-Heating Electrical Station allows to provide a cheap heat, hot water and electricity at the location. In addition, the heat transfer agent can be easily adjusted, according to the outside temperature. Further, energy security and reliability is increased, since nowadays the main equipment of Russian CHP (Combined heat and power station) is worn out by 90%. As a result emergency power system shutdowns can start.
- Application of STP, along with a gas turbine allows to organize high ecological and economical combined cycle.
As a source of steam for the steam turbine (STP) can be used steam boiler that runs on any fuel, and in a series of combined cycle gas turbine (CCGT) - heat recovery boiler.
CCGT construction allows performing a capital repair and assistance service on site without dismantling and sending to the manufacturing company. Booster station is not required. The gas turbine is used as the drive generator.
Specified life of CCGT – 20 years.
CCGT is economical, environmentally friendly, fireproof.

Application of steam turbine plant STP:
Provides consumers with heat and electricity

Commercial prototype of STP with generator installed on research and manufacturing association «Avtomatika» in Ekaterinburg. Currently released the detailed documentation for serial production of STP with electric power from 0.25 to 10 MW and heating power from 1 to 30 MW and steam turbine is certified for serial production.
STP construction:
- Frame
- Generator
- High pressure turbine
- Low pressure turbine
- Heat exchanger
- Automation system
Steam turbine plant is designed for use in existing or newly built steam boiler stations. Separate building and expensive base are not required for the installation of the steam turbine plant. Turbine unit is located directly in the machine room of boiler station.
Absence of oil system in STP construction provides fire safety.
Small metal intensity and size allow running a quick warming and start of STP and also allow to place it on the same frame with the generator. STP operates on rotating bearings that provides small gaps in the seals less than 1 mm., thereby the steam losses are reduced. Moreover, seals on the shaft allow excluding ejector suction seals and the heat exchanger from the turbine plant. Due to this solution steam losses are eliminated.
Multi-stage steam expansion performed on one wheel, thereby dimensions and weight of STP are reduced.
STP works well in variable regimes and heat duty regulated by pressure in the heat exchanger - condenser. Pk = 1at - T = 1000°C; Pk = 0,5at - T = 750 °С; Pk = 0,12at - T = 500°C
DISADVANTAGES OF GAS RECIPROCATING PLANT
Spark plugs need to be changed every 3-4 months, about 0,02 rubles per 1kW of produced energy
High voltage wires
Engine oil replacement and refilling of which in the calculation on 0,45g per 1kW of produced energy (about 1,7 mln rubles/year with a power 4MW)
Oil filters, replacement of every 500-2000 hours
The presence of formaldehyde in the exhaust, which provides tight standards. so that equipment cannot be used in urban projects, even if the high chimneys are constructed. Formaldehyde utilization requires expensive ammonia catalyst.
The presence of the oil system
Overhaul through 40000-60000 hours (every 5 years), the overhaul cost is 50% of the cost of gas reciprocating plant
ADVANTAGES OF STEAM TURBINE PLANT
There is no spark plugs
No oil system
