Steam optimization research method based on 'guide word' analysis mode

Abstract

The invention discloses a steam optimization research method based on a 'guide word' analysis mode. The method comprises the following steps: S1, by taking a steam use link as a node, refining a steam use form and defining the effect of the steam use link; S2, by taking 'deviation' as a guide word, analyzing consequences of steam production and use of each node in a deviation guide word environment by expanding or reducing steam related parameters; and S3, providing countermeasures. According to the invention, the technical effects of reducing the steam usage amount of the device and improving the steam usage efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of steam research, in particular to a steam optimization research method based on a "guide word" analysis mode. Background technique [0002] As an important part of petrochemical enterprises, steam system provides steam and power for enterprises. Its stable, safe and efficient operation is the basis for the long-term and economic operation of the enterprise. The source of steam is mainly steam produced by thermal power plant (power station) and process, and the use of steam is mainly for process and heat tracing. The characteristics of the steam system are as follows: [0003] (1) The diversity of fuels makes the forms and efficiencies of thermal power boilers different, and the parameters are uneven; the process production / steam consumption nodes are also different and unevenly dispersed due to the layout of equipment and processing volume. [0004] (2) The supply and demand relationship between the ste...

Problems solved by technology

[0005] (3) The requirements for the steam pressure level of process steam make most enterprises artificially reduce the grade of high-grade, high-pressure steam by reducing temperature and decompression, so that the utilization value of steam is unnecessarily reduced

Since the steam system involves every device, it is huge and complex, and it is difficult for the staff to make timely and accurate judgments based on experience when a problem occurs, which poses a threat to the safe and stable operation of the device

[0010] The above reasons make it difficult to systematize and formulate steam system optimization

At present, the optimization and adjustment of steam production and utilization of the device is mostly based on empirical values. Without systematic comparison and accurate analysis of steam production and utilization, it is difficult to obtain reasonable data to support the optimal use of steam.
