LM6000ガスタービンプラント

Abstract

The LM6000 is a very advanced industrial gas turbine derived from an aero engine. The gas turbine has a power output of 45 MW with over 42 percent thermal efficiency at the shaft end. Many advantages are provided such as high efficiency, lightweight, compactness, and easy maintenance, to meet a variety of power requirements, e.g., electric power generation, marine propulsion, and mechanical drive applications. In particular, the LM6000 applied to medium capacity power generation plants has demonstrated high thermal efficiency. The newest configuration of the LM60OO gas turbine and the two examples of the gas turbine applied power plants are described. The two examples are of the combined cycle type, and the usage of this type is expected to increase in the near future due to increased demands for gas fueled dispersed power plants.

航転型LM6000ガスタービンは軸端出力45MW、熱効率42%以上の最新鋭産業用ガスタービンで、高効率、コンパクト、保守の容易性などの特長をもつ。本ガスタービンは発電用、舶用、機械駆動用に広く使われており、特にその高効率性をもって中規模発電プラントに多く使われてきている。本稿ではこのLM6000ガスタービンの最新形態について概説するとともに、発電プラントへの応用例として、今後の増加が予想されるコンバインドサイクルの2つの実用例を紹介する。
