Abstract

The utility model discloses a novel 100MW reaction type steam extraction and condensation type steam turbine, and relates to the field of steam turbines. The problems that an existing steam turbine unit is low in circulation efficiency, low in cylinder efficiency, poor in overall performance and high in cost are solved. One end of a high-pressure module is rotationally connected with a center hole of a front bearing box, the other end of the high-pressure module is connected with one end of a middle bearing box, a second supporting bearing and a thrust bearing are sequentially arranged in the middle bearing box from left to right, the other end of the middle bearing box is connected with one end of a middle-pressure outer cylinder, and a middle-low-pressure rotor is arranged in the center of the interior of the middle-pressure outer cylinder. The other end of the medium-pressure outer cylinder is connected with a low-pressure exhaust hood, and a third supporting bearing is arranged at one end in the low-pressure exhaust hood. The novel 100MW reaction type steam extraction and condensation type steam turbine is applicable to the field of turbines.

Description

technical field [0001] The invention relates to the field of steam turbines, in particular to a novel 100MW reactionary steam extraction and condensation steam turbine. Background technique [0002] The steam turbine is a kind of turbomachinery used to convert the heat energy of the gas into the mechanical work. A steam turbine is a heat turbine that uses steam as a working medium and converts the thermal energy of steam into mechanical work; [0003] Electricity is the main driving force of modern production and an important condition for improving people's material and cultural life. Electricity consumption has become one of the important symbols to measure the level of a country's technological and economic development. The power industry is an industry that converts energy resources into electricity, and its development marks the degree of development of a country. At present, the main uses of steam turbines are as follows. [0004] The first use is thermal power gene...
