The New H-100 Gas Turbine: Higher Output and Efficiency

Mitsubishi has traditionally targeted large gas turbines, whereas Hitachi focused on the small and medium-size market with its H-25 and H-100 models, often referred to as the H-series. The merger of the two companies’ thermal power businesses in early 2014 created Mitsubishi Hitachi Power Systems with products spanning from approximately 30 MW to 330 MW in simple cycle. Recent mid-size capacity additions include the H-100(110), H-50, and an uprate of the H-25 gas turbines to 42 MW.

GE Ups 9HA Specs Following Completion of Validation Testing

After 200 hours of validation testing, GE has increased the efficiency rating for their HA series turbines by about a half point. For example, the 7HA.02 which had a simple cycle net output of 330 MW and 61.2% combined cycle efficiency last year is now rated at 337 MW simple cycle and 61.9% combined cycle efficiency in a 2x1 multi-shaft configuration.

HEPA Filter Advantages Cited in Turbomachinery Article

James Ross of AAF says HEPA filter systems are lasting 80,000 hours. He recommends single stage reverse jet filters for pre filters. Mitsubishi has used HEPA filters for many years and they are widle used on Japanese gas turbines. Steve Medvetz of Gore says the High efficiency filter can eliminate water washing.
