Purpose and area of application
The steam turbine installation is used at industrial heating boiler-houses and thermal power stations and is designed for using steam potential which is being lost from throttling
Main advantages
- power options at individual customer requirements;
- low specific cost ($250 per kW against $400 per kW with Russian analogues and $500 per kW with foreign analogues);
- simple control;
- low specific metal consumption;
- small overall dimensions increasing the turbine mobility;
- microprocessor-based protection and automatics systems;
- fire safety.
