The high content of carbon dioxide in the atmosphere, according to scientists, is the main cause of the greenhouse effect, and the particles of ash may contain heavy metals, toxins and carcinogenic trace elements. Therefore, the question of waste disposal is particularly acute. And have greatly succeeded in this, scientists of National research Tomsk Polytechnic University (TPU). They proposed to use waste to create new fuels.
The new technology helps to fuel several tens of times more environmentally friendly than primary and solves two problems: it reduces the amount of emissions of harmful substances into the atmosphere and recycles industrial waste.
“Thermal power plant accounts for about 45% of the world’s electricity. They are sources of ash particles and water vapor, and oxides of sulfur, nitrogen and carbon, which accounts for 90-95% of all emissions. The most dangerous is considered to be the emissions of sulphur and nitrogen oxides. Connecting with atmospheric moisture, they oxidize and form a solution of sulfuric and nitric acids, which cause acid rain. And increasing the concentration of nitrogen oxides in the atmosphere destroys the ozone layer that protects the Earth from ultraviolet space radiation,” — said one of the authors of the development, head of Department of automation of heat power processes TPU Pavel Strizhak.
Experts of TPU in experiments developed organochlorine fuel composition (AVUT). They represent a liquid composite substance, approximately 80% of which is coal conversion products. As components of OVOOT used 4 groups of substances: combustible solid components, from among low-grade coal and waste coal, liquid fuel components, water, and a plasticizer. Each individual component is unusable as fuel for the “big” energy. But together they make a fuel similar to traditional coal energy performance.
“Our results open perspectives for wide application of AVUT how cheap energy and environmentally beneficial fuel compared to coal. Using liquid fuel products from coal conversion, producers reduce the volumes of extraction of minerals and the rate of development of new deposits. This will allow you to conserve resources and reduce harm to the environment”.
