SakhaNews: Eco-friendly heat generation at Polyus Aldan

In addition to the central boiler house at Polyus Aldan, which ensures an uninterrupted supply of heating to the Company’s production sites, as well as to residential and social facilities across Nizhny Kuranakh in Yakutia, the company operates two further auxiliary heating plants. These plants help to maintain optimal temperature levels at the general-purpose transport convoy of the Road Transport Department and the Kuranakh mine.

One distinctive feature of the auxiliary heating plants is the usage of hot water as the heat transfer medium rather than steam coming from the central boiler room. The plants operate supported by specialised production units, and each heating plant is equipped with a well, ensuring that water is fed from a depth of 150m into an accumulation tank, from which it is pumped to the boilers for heating and circulations throughout the heating system, undergoing necessary purification and sodium cation softening processes.

Artem Afanasiev, head of the heat and water supply department at Polyus Aldan, commented:

We are constantly working to improve, upgrade and automate our systems, and have now installed new 1.25 MW boilers at our auxiliary heat plants, which match the highest standards. This has increased the temperature in the heat conductors by 4-5 degrees.

Polyus Aldan cares about the environment. This is evidenced, alongside other initiatives, by new battery cyclones, which have been installed at the heating plants and are used to purify the emitted gases. The effects of these measures are clear to all: the snow in the town and surrounding areas is becoming visibly cleaner, and traces of coal dust and ash in flue gases have been reduced to near-zero levels. For many years, the heating season meant local residents were faced with black smoke in the air above the boiler houses, especially around the processing plant. In recent years, however, the situation has changed remarkably — the smoke has been purified for the benefit of local people.

This is a direct result of management’s approach to the environment, and of their taking the responsibility to care for the plant’s surroundings.
