Compilation Description

N60-8.83 type steam turbine is a 60 MW turbine model that is designed and manufactured based on the advanced technologies that are introduced domestically and internationally. It is a new kind of condensing turbine of impulse type, high temperature, pressure and single cylinder. It matches boiler of corresponding capacity and steam turbine generator to form thermal generation unit. It is of basic load in electricity grid, and can also regulate the peak.

The control system of this unit is low pressure electric regulation. 控制系统是低压电液控制

This instruction manual mainly describes the general design of the unit and the structure of the turbine proper. Please refer to related technical documents provided with the machine for detailed descriptions on related auxiliaries, governing, protection and safety systems, installation and maintenance, start-up and operation, and various systems. If the instruction conflicts with technical documents provided, the documents shall prevail. In this instruction the pressures for the thermal system are presented in absolute pressure. The instruction uses legal measuring units system which can be converted .into engineering measuring units by means of the following:

Force: 1 kgf = 9.8067 N Pressure: 1 kgf / cm2 = 0.098067 MPa Heat: 1 kcal = 4.1868 KJ

Note: definitions of \generator, the left hand side is defined as the \Definitions of \close to the generator is defined as \
