Shaanxi has made new breakthroughs in clean and environmentally friendly utilization technology

The new energy company of Shaanxi Coal Chemical Group has made new breakthroughs
in the clean, environmentally friendly and efficient utilization technology of coal.
After screening, washing, grinding and grading, the raw coal is turned into micron-sized pulverized coal finer than flour, and converted into high-temperature heat energy
through special boiler combustion.
Tests show that each ton of pulverized coal can reach 1.
5 tons of raw coal heat
.
30%
lower cost compared to natural gas.
The three emissions of soot, sulfur dioxide and nitrogen oxides are lower than the national emission standards
.
Experts believe that this move could find a new way out of excess coal capacity and bring a glimmer of light
to the sluggish coal industry.

A few days ago, in the thermal energy power center of Xianyang Xinxing Textile Industrial Park, the reporter saw two high-efficiency pulverized coal industrial boilers
using the technology of Shaanxi Coal Chemical New Energy Company.
The inside of the power center is clean, no smoke can be seen, no smell of coal
smells.
The staff brought a bottle of pulverized coal, which was indeed finer
than flour.
At the boiler exit, the reporter saw that the ash residue remaining after the combustion of pulverized coal was
sandy.

The inspection order of Xianyang Environmental Monitoring Station on October 19, 2015 showed that the smoke emission of the two boilers was 13.
9kg/h, the sulfur dioxide concentration was 28.
3mg/m, and the nitrogen oxide concentration was 22.
5mg/m, and the pollutant emission was lower than the national standard and better than the emission standard
of natural gas boilers.

According to Fang Gang, executive director and general manager of Shaanxi Coal Chemical New Energy Company, as early as 2012, they began to explore the use of physical processing methods to process raw coal into pulverized coal fuel
.
The processed coal powder is finer than the flour, reaching more than 200 mesh, while the extra grade flour is about
90 mesh.
Pulverized coal is different from loose coal in the traditional sense, which is centimeter-level or millimeter-level, while pulverized coal reaches the micron level, and the particle size is reduced by more than
a thousand times.
When used, the combustion efficiency is improved, it is more energy-saving, and it has the characteristics
of micro-emission and cleanliness.

After nearly three years of scientific and technological research and development and practical exploration, the clean, environmentally friendly and efficient utilization technology of coal developed by Shaanxi Coal Chemical Group New Energy Company has been affirmed by experts and recognized by the market
.
At present, the company has registered the "Shenfeng" brand pulverized coal and built the largest pulverized coal production base in China, with an annual digestibility of 300,000 tons
of raw coal.
There are 13 central heating projects using this technology in China, covering Shaanxi, Tianjin, Ningxia, Hubei, Hebei and other places
.
In addition, hundreds of enterprises came to visit and discuss cooperation
.

Relevant experts believe that China's "oil-poor, low-gas, coal-rich" energy endowment structure makes it difficult to change
the coal-based energy consumption structure in the short term.
There is no "original sin" in coal, and the direct and extensive burning of coal has long been the main cause of
pollution.
After clean and environmental protection technology treatment, coal can be turned into green and efficient new energy
.
The clean, environmentally friendly and efficient coal utilization technology developed by Shaanxi Coal Chemical Group New Energy Company is of great significance, which can find a new way out for excess coal production capacity and bring new hope
to the sluggish coal industry.
