Turbine Warming System

Increasingly, utility companies are discovering that a relatively small investment in a turbine warming system can save millions of dollars in repairs and subsequent fuel costs. It also eliminates humping-induced blade seal wear and reduces start-up and maintenance costs. The Bolttech Mannings turbine heating system is the highest-quality, lowest-cost system available.

The Bolttech Mannings turbine warming system is designed to keep the turbine warm in any power plant, reducing the fears of "slugging" water and reducing the required start-up time. This is especially helpful for today’s "peaking" power plants. The standard unit consists of three custom-wound transformers totaling 195 kVA. These transformers are full isolation and include a grounded static shield between the primary and secondary windings. The standard input voltages are 380/415/480 and 575. These are mounted in to a 72" x 72" x 24" cabinet, providing up to 28 zones of control. Several control packages are available utilizing well-known temperature controller brands. Others are available upon request. We provide relay contacts for the desired alarms so that the customer can connect to their control system using a PLC or other interface system. The controllers used will dictate the communications options allowing remote temperature monitoring.
