Unix Engineering LLC implements EP/EPC power plant projects.
A power plant is an industrial enterprise that generates electricity to supply various consumers.
Electric stations are divided according to the following criteria:
By type of natural energy used:
a) hydroelectric power stations (HPP), in which electrical energy is generated from the mechanical energy of river water;
b) thermal power plants (TPPs) using fossil fuels;
By type of energy released:
a) thermal power plants that supply only electrical energy - condensing power plants (CPS);
b) thermal power plants that supply electrical and thermal energy - combined heat and power plants (CHP). The source of released heat is exhaust steam or combustion products of a heat engine.
By type of heat engine:
>a) power plants with steam turbines - steam turbine thermal power plants. They are the main type of power plants in Russia and abroad;
b) power plants with gas turbines - gas turbine thermal power plants;
c) power plants with combined cycle units - combined cycle thermal power plants;
Intended use:
a) district power plants that serve all types of consumers in the region and are independent enterprises;
b) industrial power plants that are part of manufacturing enterprises and are intended mainly to supply energy to enterprises and adjacent urban and rural areas.Steam turbine power plants differ:
by total and unit power of units
- Small - up to 25 MW
- Medium – 50 – 100 MW
- Large - >200 MW
according to the initial parameters of the pair
- Low pressure - up to 3.92 MPa
- High pressure - up to 12.7 MPa
- Ultra high pressure - up to 23.7 MPa
according to the technological diagram of connections of steam generators and turbogenerators
- Block (turbogenerator is attached to a specific steam generator)
- Non-block - the turbogenerator is connected to all steam generators of the station or part of it.
Offered main equipment: boiler-steam generator, turbine, generator, steam condenser, circulation pump, etc.
