Advantage of Horizontal Machines

Advantage in Design:
  • Simple in Design (Standardized size available)
  • Hydraulic path is simpler (No distributor for tubular)
  • No Complicated parts
  • Even distribution of load on foundation (as turbine load come at different place and generator load at different place etc.,)
Advantage in Efficiency:
  • Better efficiency for lesser MW project (as flow is straight and Hydraulic passage is of lesser restriction to flow.

Advantage in Layout:
  • Simpler Layout (all auxiliary equipment can be placed in one floor and close to main generating equipment - Better coordination by operator)
  • Entire equipment is directly under crane hook making approach very easy for erection, maintenance - Reduce down time during maintenance.

Advantage in Supply:
  • As design is simpler and standardized, quicker delivery period.
  • All equipment can be supplied in 6 to 12 months.
  • Saving in delivery period of the order of about 6 months

Advantage in Erection:
  • Erection time is less (as equipment distributed on one floor)
  • Machine (turbine as well as generator) can be fully assembled in shop / service bay and lowered to foundations.
  • Results in shorter erection & commissioning time (3 to 6 months)

Advantage in Operation:
  • Easier control and vigil (operator sitting in control room can see all the equipments and can take preventive shutdown, if required)
  • No skilled personnel are required. As no complex parts are involved thus, easy to understand the parts and system.

Advantage in Maintenance:
  • Simple design; hence availability of spares is easy.
  • Easy Maintenance; All equipment are exposed in Horizontal formation thus can be maintained independently like turbine & Generator independently.
  • Also the Turbine is exposed (not fully buried in concrete) thus inspection, repair, maintenance etc., is easier.
