Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer system for mediating between a boiler company and a power company, which is an administrator of a boiler, in repair work and the like based on a result of performance diagnosis of the boiler.

[0002]

Boilers in thermal power plants and the like are
In order to prevent failure due to deterioration of members with the lapse of time, it is necessary to regularly perform performance diagnosis. Conventionally, performance diagnosis is
It was carried out by the manufacturer who constructed the plant by visiting the site and conducting inspections and inspections. When a repair point is found, or when the electric power company desires a modification for improving the performance, the manufacturer procures the parts and constructs the boiler.

[0003]

In the above method, the electric power company, who is the manager of the boiler, has to carry out diagnosis and construction of the boiler in connection with a specific manufacturer. For this reason, for example, in order to reduce costs, it is not possible to compare the cost of the construction, the construction period, and the like with other manufacturers, and select a manufacturer with good conditions to outsource the construction.

Also, for the manufacturer, it is laborious to go to the site and diagnose the performance of the boiler. Moreover, it is not possible to cultivate new customers simply by procuring equipment and conducting construction in connection with a specific electric power company.

An object of the present invention is an electric power company which receives a performance diagnosis of a boiler and orders a boiler construction based on the result.
Another object of the present invention is to provide equipment necessary for boiler construction and to provide a computer system that can reduce the load on the manufacturer who performs the construction.

[0006]

In order to solve the above-mentioned problems, according to the present invention, there is provided a computer system for transmitting and receiving information via a computer network, wherein a design value, operation data and measurement data of a boiler are stored. When accepted, the boiler performance is diagnosed, the diagnosis result is output, and the boiler diagnosis means for outputting improvement point information including equipment information and construction information necessary for improvement, and equipment information and construction information necessary for the improvement. And a cost delivery date acceptance means for receiving the cost and delivery date estimate for the equipment, and a plan formulation means for formulating a cost and construction period plan for improving the boiler based on the received cost and delivery date estimate, There is provided a computer system comprising: a plan output means for outputting the established plan.
