Background technology
Mitsubishi M701F4 combustion engine one-to-one multiaxis Combined Cycle Unit main buildings conventional design is currently based on mostly using height
Position arrangement.By taking two units as an example, the arrangement typically uses complex factories, and two combustion engine are arranged in main building both sides, two
Platform steam turbine is arranged in centre, and combustion engine low-position air inlet, exhaust diffuser is followed by waste heat boiler.Because combustion engine, steam turbine are using a high position
Arrangement, operating layer settable maintenance large platform, easy access part is put, but adds combustion engine, the design of steam turbine pedestal
Difficulty and Civil Cost.From the point of view of maintenance lifting, driving rail top mark height and main building roof absolute altitude certainly will be raised, no
Beneficial to reduction main building volume and reduction construction investment.On the other hand, combustion engine, steam turbine high position arrangement are also brought necessarily not to installation
Just, also it is unfavorable for shortening civil engineering duration and equipment installation period.
To solve problem above, have at present in the disclosed technical scheme in part and consider combustion engine low position, high-positioned air inflow side
Formula, but the arrangement merely reduces combustion engine base height, reduces combustion engine pedestal construction investment.Because steam turbine is still used
High position arrangement, driving rail top mark then can not be still reduced up to the main factory of reduction according to the shared driving of the full factory of complex factories
Room volume reduces the purpose of construction investment.
The content of the invention
It is an object of the invention to overcome the shortcomings of that prior art is present both to have can guarantee that what full factory's maintenance was lifted by crane there is provided a kind of
The reasonable Arrangement of equipment pipe in convenient, main building, can reduce main building volume again, and the one-to-one multiaxis of reduction investment, which is combined, to follow
The complex factories low position structure of ring firepower generating set.
The purpose of the present invention is completed by following technical solution, a kind of one-to-one multiaxis combined cycle thermal power generation
