Air Protection at EC Zagłębie Dąbrowskie sp. z o.o.
As part of its environmental strategy, the company consistently implements pro-ecological investments aimed at minimizing the impact of its production facilities on the natural environment.
To ensure air quality, each power boiler is equipped with high-efficiency electrostatic precipitators, ensuring effective reduction of dust emissions. One of the key projects was the project entitled “Construction of a Flue Gas Desulfurization and Denitrification System at Elektrociepłownia BĘDZIN Sp. z o.o.,” which resulted in the boilers being retrofitted with a semi-dry Flue Gas Desulfurization System with a circulating fluidized bed (CFS) reactor. This system enables effective reduction of emissions of sulfur oxides (SO₂, SO₃), hydrogen chloride (HCl), and hydrogen fluoride (HF).
The flue gas cleaning system is complemented by a high-efficiency bag filter, which captures and separates reaction products from the flue gas stream before they are discharged into the atmosphere. As part of the project, nitrogen oxide (NOₓ) reduction systems were also implemented on each boiler, based on two complementary methods:
• the primary RROFA method, which involves the staged and controlled addition of air to the combustion process, and
• the secondary non-catalytic SNCR method, implemented by injecting a urea solution into the combustion chamber (RRMIX system).
Exhaust gases from all boilers are discharged to a common emitter, equipped with a continuous monitoring system, enabling ongoing monitoring of emission parameters.
The technological solutions used significantly reduce the amount of pollutants released into the atmosphere and ensure compliance with applicable emission standards.
