Fabric Collectors

As environmental standards and regulations for dust emission are getting stricter and stricter, Halla Energy & Environment developed the high efficient fabric collectors by improving the large scale electrostatic precipitators which were mainly used in cement kilns and proven the better performance and results. Also, our air coolers and fabric collectors of high efficiency that is the pre-treatment facility at the steel mill where the large volume of high-temperature is emitted maintains reputations at all installation sites for its superior performances

The flue gas desulfurization (FGD) system removes sulfur oxides present in flue gas produced in boilers and power generation plants utilizing coal or heavy oil as fuel. Halla’s FGD system having well-arranged nozzles to spray overlapping in several layers according to the gas flow, has outstanding efficiency in removal of sulfur oxides. Also, Halla FGD offers the advantages of economical initial investment and low operation & maintenance costs as well. High purity gypsum, a by-product, can be used in making gypsum board, an adhesive mixture for cement, an improving agent for soil and as a road paving material.

Halla Energy &Environment is equipped with its own design and supply capacity for selective catalytic reduction (SCR) flue gas denitrification systems. Halla has successfully executed construction of a denitrification system for unit #4  of the Seoul thermal power plant, the first denitrification facility installed in a thermal power plant in Korea. The selective catalytic reduction (SCR) is the system to decompose nitrogen oxide generated from combustion into harmless nitrogen and vapor before emission to atmosphere by passing the exhaust nitrogen through the catalytic layer along with reductants (ammonia or urea).
