Qingyang, located at the junction of Shaanxi, Gansu and Ningxia provinces, is the second largest city of energy resources in China and an important petroleum and natural gas chemical base in Gansu Province. The large-scale chemical industry cluster not only promotes the rapid development of regional economy, but also brings serious pollution problems to the environment.
Gansu is one of the central heating provinces, the high needs of life and production heat have put heavier load on the environment. In order to alleviate the pressure of air pollution in winter and improve the current situation of high demand and high discharge of heating, Qingyang City has issued an in-depth prevention and control strategy implementation plan, actively promoted the heating reform and expansion work, and resolutely laid a solid foundation for the 2030 peak carbon dioxide emissions target.
The altitude of Qingyang is between 885-2089, the regional air is thin, and the volume fraction and density of oxygen are higher than those in plain areas, which also leads to the oxygen level in Qingyang City being less than 21%.
Low oxygen concentration often results in insufficient combustion or oxygen-deficient combustion of fuel, which leads to problems such as excessive flue gas, substandard heat load and tempering.
Last year, EBICO provided high-altitude heating solutions for Xining, Qinghai in the heating season, which helped the heating work in Xining to start smoothly. Our rich experience and environmental protection ability coincide with the thermal demand of Qingyang at high altitude, and we have reached a friendly and cooperative relationship.
Generally, the actual heating load affected by altitude will exceed the rated power of burners. Therefore, according to the heat demand of 116MW in Qingyang City, EBICO selected four EC-GR series low nitrogen burners, leaving enough room for proportional adjustment.
Except the burner itself, the air supply system of EBICO takes into account the specific installation of combustion air flow rate, combustion space pressure and high altitude environment, and the multi-channel air supply technology keeps the air volume even and stable. The LMV intelligent control system is also specially designed according to the plateau characteristics, and the functions of correction and compensation are realized through programming.
In addition, the low pressure environment will also affect the mixture air density, change the range of gas jet, and affect the flame shape. EBICO’s flame fine-tuning technology perfectly solves these problems.
Supermixing technology also supports the use of infrasonic velocity of fuel, and the flame is generated after the fuel and air are fully mixed, so as to control the oxygen level in the combustion space, reduce the NOx emission to less than 30mg, and achieve the environmental protection goal of carbon and nitrogen reduction.
EBICO's outstanding performance, professional technology and service keep the heat flowing continuously, warming thousands of families in the cold wind of the Loess Plateau. The year 2030 is getting closer and closer, and the peak carbon dioxide emissions's goals has entered the most intense stage. EBICO implements the concept of corporate environmental protection, cooperates with Qingyang City to build an ecological security barrier, and at the same time, unswervingly moves towards a "double-carbon" future.
