These mechanisms are indicated in Table 1 along with the resultant damage and typical causes of failure. For steam turbines to operate with high reliability and availability, the ability to
Get PriceElliott steam turbines are rated for inlet steam conditions up to 2000 psig/1005 degrees F and speeds up to 20,000 rpm. Elliott steam turbines come in a variety of sizes ranging from small, 20 HP (15 kW) single-stage units, to large 175,000 HP (130,000 kW) multi-valve, multi-stage extraction condensing units.
Get PriceWith a view to maximum energy yield, the aim of the turbine control system is to maximize this product under all operating conditions. Blade pitch is adjusted during operation to regulate power output according to the altering airspeed and airflow. If the flat sides of the blades are perpendicular to the airflow, the turbine does not turn.
