paper on boiler flue gas desulfurization and dust removal

What are the main methods of desulfurization and

(1) The flue gas of 2T and 4T boilers enters the bag-dusting equipment through pipes (two bag-dusters, one bag-dusting of 2T boiler and one bag-dusting of 4T boiler).(2) Dusty gas from the diversion pipe into each unit filter room, due to the design of the vertical distance from the bottom of the filter bag to the top of the inlet outlet has enough, reasonable airflow through the appropriate diversion and natural flow

Semi-Dry Flue Gas Desulfurization

The invention provides a dry flue gas desulfurization, denitrification and dedusting integrated purification process. The process comprises the steps that coal boiler fuel gas is subjected to preliminary denitrification through an SNCR denitrification system and enters into a gas duct, dust in the fuel gas is removed through a dedusting system, secondary purification of the fuel gas is

Integrated Dust Removal System for Desulfurization and

The sulfation properties of six different natural limestone and hydrated lime slurries were investigated. Sulfation experiments were carried out at the temperatures of 323 K and 298 K in a gaseous mixture consisting of 5% O2, 10% CO2, 0.5% SO2 and a balance of nitrogen by volume. Total sulfation capacities of the slurries were found to vary depending on sulfation temperature, sorbent

Synergistic removal of dust using the wet flue gas

Jul 03, 2019 · Wet flue gas desulfurization (WFGD) technology is extensively used to control SO 2 emissions in power plants. However, only limited studies have investigated the synergistic dust removal by the WFGD system. Spray scrubbers and sieve-tray spray scrubbers are often used in WFGD systems to improve the SO 2 removal efficiency. In this study, the
