In modern steel plants, primary emissions arise from Basic Oxygen Furnace (BOF), Electric Arc Furnace (EAF), and ladle metallurgy processes. These gases contain particulate matter (PM), CO, NOx, SO₂, and dioxins, requiring advanced gas cleaning systems (GCS).
During the alloy melting process in submerged arc furnaces, there is large volume of flue gas with high temperature. Also, the composition of flue gas is very complex. Considering the chemical and physical properties of flue gas, you can select the best one for your project. In recent years, the LCM long bag type pulse filter has been wide applied for submerged arc furnaces. It can be also used for calcium carbide furnace, boiler, limestone kiln, metal mixer and asphalt mixing station to meet the requirement of national emission standard.
The ash powder will be collected and treated.
The clean gas will be emitted to atmosphere.
The fume will be separated.
The fume will flow to the filter by the action of blower.
Fume cover will be collected the dust from operation
Primary Dedusting: Wet scrubbers (Venturi type) and electrostatic precipitators (ESP) for coarse dust removal.
Secondary Dedusting: Baghouse filters (pulse-jet type) with PTFE-coated bags for fine particulate control (<10 µm).
Gas Recovery: BOF gas recovery systems (OG system or LT system) for CO-rich gas reuse in energy recovery.
