Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific examples.
[0023] figure 1 It is a schematic diagram of a low-vacuum heating steam turbine system with a capacity of 300MW.
[0024] The 300MW capacity level low vacuum heating steam turbine system consists of a 300MW capacity level low vacuum heating turbine generator set and a power plant cold end and heating load coupling regulation system. In the 300MW capacity level low-vacuum heating turbo-generator set, steam turbine high-pressure cylinder 1, steam turbine medium-pressure cylinder 2, steam turbine No. 1 low-pressure cylinder 3, steam turbine No. 2 low-pressure cylinder 4 and generator 5 are arranged in a single shaft. The high-pressure cylinder 1 of the steam turbine and the medium-pressure cylinder 2 of the steam turbine are arranged together. The shaft of the medium-pressure cylinder 2 of the steam turbine is connected with the shaft on one side of...
