- High efficiency (generally greater than 85%) hence reduced fuel consumption.
- Flexibility of design -- important space consideration.
- Capable of high out put (i.e. high evaporation rate).
- High pressures and temperatures improve turbine plant efficiency.
- Flexible in operation to meet the fluctuating demands of the plant, - superheat control rapidly responsive to changing demands.
- Generally all surfaces are circular hence no supporting stays are required.
- Steam can he raised rapidly from cold if the occasion demands, (3 to 4 hours compared to 24 hours for a Scotch boiler) because of the positive water circulation.
Compact and relatively light (water content up to 7.5 tons compared with 30 tons for a Scotch boiler).
- With double easing radiation loss can he cut to 1% or less.
The electrohydraulic control mechanisms of the ME engine replace the following components of the conventional MC engine: Chain drive for camshaft Camshaft with fuel cams, exhaust cams and indicator cams Fuel pump actuating gear, including roller guides and reversing mechanism Conventional fuel pressure booster and VIT system Exhaust valve actuating gear and roller guides Engine driven starting air distributor Electronic governor with actuator Regulating shaft Engine side control console Mechanical cylinder lubricators. The Engine Control System of the ME engine comprises: Control units Hydraulic power supply unit Hydraulic cylinder units, including: Electronically controlled fuel injection, and Electronically controlled exhaust valve activation Electronically controlled starting air valves Electronically controlled auxiliary blowers Integrated electronic governor functions Tacho system Electronically controlled Alpha lubricators
