  Build 46 kilometers of steam transmission pipe network to provide clean heat source for enterprises.

On September 19, the Yangtze River Daily learned that since the first phase of the Dongxihu District Central Heating Project was put into operation a year ago, the 34 household gas companies in the region have used 540,000 tons of gas annually, which is equivalent to reducing carbon dioxide emissions by more than 80,000 tons, and achieved a good ecological environment. benefit.

  ■ The boiler room becomes a temporary "utility room", saving nearly 10 million yuan a year

  On the morning of September 17, a reporter from the Changjiang Daily came to Huitong Road in Zuomaling Industrial Park, Dongxihu District, and saw that a 4.5-meter-high blue pipeline crossed the road and connected to the green steam transmission pipeline to Jianhua Building Materials (Hubei). The factory area of ​​a limited company.

  "We are a concrete product manufacturer, and steam is used in the steam curing and autoclave process of concrete products." Hu Qingsong, assistant electrical engineer and boiler supervisor of Jianhua Building Materials (Hubei) Co., Ltd., said that traditional steam production relies on gas boilers, but when gas is used During stressful periods, the production cycle is long and environmentally friendly.

With cross-zone steam, you only need to prepare your own steam pipe and pressure-reducing device to use the steam. The pipe pile product construction period is compressed from 28 days to 13 hours, the quality control is more stable, and the product quality is more guaranteed.

  The reporter saw in the production plant that the company's three large gas-fired boilers have been out of use, the 25-meter-high chimney has been removed, and the boiler room has become a temporary "utility room" for the company.

  "Cross-zone steam makes production more environmentally friendly, and realizes energy saving and consumption reduction." Zhu Xin, director of the General Manager Office of Jianhua Building Materials (Hubei) Co., Ltd., introduced that since the gas boiler was shut down in June last year, the comprehensive operating cost of steam usage has been reduced by about 30%. , It has saved nearly 10 million yuan in cost during one year of operation.

  ■ 34 companies use clean energy, the "temperament" of Dongxi Lake is the first in the city

  It is reported that in 2017, Dongxi Lake District and Hanchuan Power Plant reached a strategic cooperation to introduce steam generated by the waste heat of Hanchuan Power Plant's power generation into Dongxi Lake through pipeline transportation, with an annual gas supply capacity of 2 million tons.

Jianhua Building Materials (Hubei) Co., Ltd. has become the "last stop" of this super pipeline.

  He Song, the relevant person in charge of the Dongxihu District Service Investment Group Energy Company, said that at present, Dongxihu District has invested 465 million yuan to build a steam transmission pipeline network of about 46 kilometers, which is the Zoumaling Food Industrial Park, the Mechanical and Electrical Industrial Park and the Xingou District. 34 companies such as the industrial park supply gas, with a monthly gas supply of about 45,000 tons, which is equivalent to the energy provided by 3.6 million cubic meters of natural gas.

  It is understood that in the future, there will be plans to start the Lingkong Port New City heating project, including industrial heating and civil heating, and the total length of the planned new pipeline is about 23.5 kilometers.

  The reporter learned from the Office of the Leading Group for the Improvement of Air Quality in Wuhan that from January to August this year, the Dongxihu District ranked first in the overall ranking of the city’s air quality improvement and air pollution prevention and control work, and was named the "Red Flag District". ".

  The relevant person in charge of the Dongxihu District Bureau of the Municipal Ecological Environment Bureau said that energy saving and emission reduction of enterprises is one of the important measures to improve air quality in Dongxihu District. The carbon effect is "immediate."
