The implementation of centralized air supply project provides compressed air for 56 families at the same time.

According to China Electric Power News Network on September 23, the first centralized compressed air supply project in Shaoxing Binhai Industrial Zone, Zhejiang Province, has officially landed and is about to start construction. After the completion of the project for the surrounding 56 printing and dyeing enterprises to provide nearly 3000 standard cubic meters per minute of compressed air.

Recently, the signing ceremony of the compressed air supply and sales contract of Zheneng Shaoxing Binhai Thermal Power Company was successfully held. The first batch of 15 large printing and dyeing enterprises signed contracts with Binhai Thermal Power Company.

This means that the first centralized compressed air project in Binhai Industrial Zone, the largest printing and dyeing distribution center in the Asia-Pacific region, has officially landed and is about to start construction. After the completion of the project, it will save nearly 20000 tons of standard coal annually and provide nearly 3000 standard cubic meters of compressed air per minute for 56 printing and dyeing enterprises in the surrounding area.

Binhai Thermal Power Company's centralized compressed air supply project was approved in January 2019, with a total investment of 0.22 billion yuan. It is planned to build 4 0.9MPa steam turbines to drive centrifugal air compressor units, 2 0.9MPa electric centrifugal air compressors as backup, and simultaneously build compressed air pipelines outside the plant.

As early as the end of 2017, Binhai Thermal Power Company found in the investigation of surrounding printing and dyeing enterprises that there is a huge potential market for centralized supply of compressed air to printing and dyeing enterprises. With the full support of leaders at all levels of the group, the power sector and the company, the coordinated efforts of several departments and the strong cooperation of surrounding enterprises, after several years of on-the-spot visits to investigate the market response, compilation of feasibility reports, carpet mapping of all potential customers' air compressor models, and investigation of the total compressed air demand in the region, etc., a lot of preparatory work has been done.

Through the centralized supply of compressed air, it can effectively replace the existing scattered small air compressor in the region, improve the level of energy consumption, reduce the production cost of printing and dyeing enterprises, reduce the total energy consumption of the printing and dyeing industry agglomeration area in the coastal industrial zone, and improve the regional investment environment.

It is reported that the signing of this contract is an important step for Binhai Thermal Power Company to develop a circular economy and practice green development. It is also a landmark event for Binhai Thermal Power Company to expand from traditional cogeneration to integrated energy supply. It is the company's creation of a regional integrated energy service platform. Milestone goal. The development of the compressed air supply project has made an important contribution to the energy saving and consumption reduction of the coastal printing and dyeing agglomeration area, and at the same time enriched the energy supply model of the Bindian Company. On the basis of cogeneration, the energy development model of heat, electricity, gas cogeneration and heat, electricity and gas cogeneration will provide economic, high-quality and stable energy guarantee for the economic development of the entire coastal industrial zone.

Spicy comments:

on the surface, this is just a super big single settlement news, but some of the information leaked out is worthy of our attention:

1. The author has heard of the "centralized gas supply" model at least ten years ago, which is not new, but there are few successful cases. The reason for this is nothing more than the production-to-investment ratio and market position. With such a heavy asset model, it is extremely difficult to operate purely commercially.

The project in the news seems to be logically feasible: a textile printing and dyeing industry concentration area that requires a lot of heating and compressed air, and a thermal power plant with a state-owned background in the province that provides heating for it, whether it is capital, market position or Business path are perfectly matched. In other words, only such enterprises have the conditions to carry out centralized gas supply business model.

For air compressor companies or air compressor energy-saving service companies, does this indicate a new market opportunity?

2, it is generally believed that large centrifuge units are superior to screw air compressors in efficiency. However, the words are divided into two sides. Such a large-scale centralized and constant pressure and unified gas supply may not be energy-saving.

The first reason is that the pressure loss of long-distance pipeline transportation of compressed air is the threshold that cannot be bypassed. Secondly, can the pressure required by various enterprises really be unified? (guess the pressure of 0.9MPa, which is estimated to be determined by the pressure loss of the highest pressure pipeline required by the research enterprise, which is contrary to the latest energy-saving technology of air compressor system).

Of course, the owner of the project is a thermal power plant, which has inherent advantages in energy costs, and perhaps for the purpose of comprehensive utilization of thermal energy in the thermal power plant, that is another matter.

Finally, no matter what, congratulations to the air compressor company that won the project!
