3 Enterprise Development Editor

The third phase expansion project of Yangliuqing Thermal Power Plant started in June 1996, and two 300MW coal-fired heating units were built in the third phase. The units were put into operation in1February 1998 and1September 1999 respectively, with an annual designed power generation of 3.9 billion kwh and a designed heating area of about 7.6 million square meters. The biggest feature of the two units in the third phase is their remarkable environmental protection performance. German liquid slag discharge furnace is introduced into the boiler, which has a good environmental protection effect. There is a fly ash re-ignition system, which only discharges slag and does not discharge ash, thus avoiding the pollution of dust flying and ash flushing water to groundwater. The dust removal efficiency of electrostatic precipitator is more than 99.7%, and the dust emission concentration is lower than the national emission standard 1 times. Other environmental emission indicators are far below the national standards.

The fourth phase expansion project of Yangliuqing Thermal Power Plant started construction on May 28th, 2005. Two 300MW coal-fired heating units were built in the fourth phase of the project, which were put into operation in February 2006 and May 2007 respectively. The annual designed power generation is 3.3 billion kWh, and the designed heating area is about120,000 square meters. The fourth phase of the project has three characteristics: first, cogeneration can replace 12 1 scattered small boilers in the existing 70 small boiler rooms in the heating area; Second, the design water utilization rate, this project in addition to domestic water tap water, industrial water can all choose urban water; Third, environmental protection facilities are complete, limestone-gypsum wet desulfurization system is built, high-efficiency electrostatic dust removal equipment and flue gas continuous monitoring device are installed, and all emission indexes will reach the national environmental protection standards.

4 Environmental Requirements Editor

Huaneng Yangliuqing Power Plant fully considered the requirements of social development for environmental protection, and introduced the German liquid slag furnace with good environmental protection effect. After commissioning, the environmental protection indicators of the power plant are far superior to the national standard level.

The boiler is equipped with 100% fly ash reburning system. The unit can only discharge slag, not ash. At the same time, sealed dust-proof measures are adopted in the loading and unloading process of ash storage and slag storage, which effectively avoids the pollution of dust flying and ash flushing water to groundwater. Due to the good quality of power plant ash, ash can be used as raw materials for concrete and mortar admixture, and ash can replace building sand, which has been in short supply since it was put into production.

Yangliuqing Power Plant has the highest chimney of 240 meters in domestic power plants, which makes full use of the diffusion and dilution ability of the atmosphere and reduces the ground concentration of pollutants.

Adopt high-efficiency five-electric field electrostatic precipitator. The dust removal efficiency is more than 99.7%, and the actual maximum emission concentration of smoke and dust of the two units is 36.3 mg/m3 and 33.5 mg/m3, which are 24.2% and 22.3% of the national emission standards respectively. The actual smoke emission of the two units is 5 1.48kg/h, accounting for 29.7% of the design emission.

The coal powder milled by using classified cyclone burner, lean oxygen combustion and MPS medium-speed coal mill with rotary separator is finer than that by ordinary coal mill. The actual maximum emission concentrations of nitrogen oxides of the two units are 578. 1 mg/m3 and 588.4 mg/m3, which are 57.8%h and 58.8% of the national standards respectively.

Because of insisting on burning low-sulfur coal (sulfur content is only 0.33%), the actual maximum emission concentration of SO2 is 348 mg/m3 and 526 mg/m3, which are 16.6% and 25. 1% of the national standards respectively. The actual total emission of the two units is 768kg/h, which is 20% of the national standard.

Yangliuqing Thermal Power Plant adheres to the concept of Huaneng Group Tricolor Company, actively fulfills its social responsibilities and serves the people's livelihood in Tianjin. In 2006, 654.38+0.8 billion yuan and 654.38+0.9 billion yuan were invested to carry out desulfurization technical transformation for the third phase project, and desulfurization equipment was newly installed for the fourth phase project. On May 29th of that year, the Ministry of Environmental Protection held an on-site meeting at the desulfurization construction site of Yangliuqing Thermal Power Plant, and signed a letter of responsibility for sulfur dioxide emission reduction targets with seven provincial governments such as Shandong and six major power companies such as Huaneng, marking the official start of the desulfurization project of coal-fired power plants in the "Eleventh Five-Year Plan".

Yangliuqing Power Plant Plan [2]

Development is the supporting point for enterprises to achieve sustainable scale expansion and improve efficiency. Yangliuqing Thermal Power Plant has a planned total installed capacity of 3,000 MW, and after deducting the current operating capacity of 1200MW, there is still an expandable capacity of 1800MW. For Yangliuqing Thermal Power Plant, the fifth phase expansion project is a concrete manifestation of its contribution to Huaneng Group. It is the starting point to achieve a comprehensive breakthrough in scale benefits, and it is the focus and breakthrough point to enhance market competitiveness and get rid of huge operating pressure. It is the consensus of investors that Huaneng Yangliuqing Thermal Power Plant Phase V expands the 2×600MW heating unit project, which is an important project to implement the development and opening up of Tianjin Binhai New Area, implement the "blue sky project" in Tianjin, improve the living conditions of Tianjin people and promote the rapid development of Tianjin.

The implementation of the fifth phase expansion project of Yangliuqing Thermal Power Plant has many advantages and conditions:

First of all, the fifth phase of Yangdian Power Plant will make full use of the idle site after the demolition of the first and second phases of the power plant, which has the characteristics of saving land resources, good demand for thermal power market, high energy utilization efficiency, using urban reclaimed water and simultaneously building desulfurization and denitrification environmental protection facilities.

Secondly, Huaneng Liu Yang Thermal Power Plant undertakes the heating task in the west of Tianjin and Yangliuqing Town. With the rapid development of urban construction in Tianjin, the heating load of the original heating area and the surrounding area of the outer ring road is increasing rapidly, and the existing heating capacity is difficult to meet the needs of load development;

Thirdly, in recent years, the load of Beijing-Tianjin-Tangshan power grid has increased rapidly, while the power supply construction of Beijing-Tianjin-Tangshan power grid, especially the power supply point construction of load center, has lagged behind seriously. Yangliuqing thermal power plant has a superior geographical location. Building two 600MW coal-fired units here for pumping water and heating will not only help alleviate the power shortage in the power grid, but also provide important support for the load center of Beijing-Tianjin-Tangshan power grid.

Fourth, the fifth phase of the project has the characteristics of less investment, short construction period and quick results. First, the existing land of the power plant can meet the construction needs, and the fifth phase project does not need to re-requisition land. Secondly, using urban reclaimed water as the cooling water source of circulating water can alleviate the increasingly tense surface water resources in Tianjin. Third, there is a broad market for comprehensive utilization of Beijing-Tianjin slag, and the existing slag yard can be used as a backup slag yard for the fifth phase of the project. Fourthly, the existing human resources of the power plant can meet the needs of the fifth phase project.

Therefore, according to the requirements of the Notice of Tianjin on the Preliminary Work of the Fifth Phase Expansion of Yangdian Power Plant, Yangliuqing Thermal Power Plant plans to use the first and second phases of Yangdian to demolish the site and expand the "Fifth Phase Project", and plans to build a 2×600MW supercritical heating unit. A lot of work was done in the early stage. In February, 2008, the General Electric Power Planning and Design Institute hosted a review meeting on the feasibility study report of Yangliuqing Thermal Power Plant's 2×600MW expansion project, which has now entered a comprehensive closing stage. In addition to the feasibility study report of the special railway line and the feasibility study report of the heating pipe network, all other preliminary supporting documents have been implemented. The fifth phase of the project has been included in the "Twelfth Five-Year Plan" of Tianjin.

In order to strive for the immediate construction once the "road strip" is obtained. On June 23rd, 2008165438+1October 23rd, Yangliuqing Thermal Power Plant dismantled the first and second power generation cooling towers, which actively created conditions for the "five connections and one leveling" of the fifth phase project. Tianjin TV conducted a live broadcast, CCTV's "News Network" program reported that night, and CCTV Economic Channel and News Channel also made special reports one after another.

At present, Yangliuqing Thermal Power Plant is positioned as the largest heating power plant in Tianjin, Bohai Rim region and even the whole country, an important strategic power supply point of Huaneng Group in the capital region, and an energy-saving, environmental-friendly and efficient modern power plant in Tianjin.
