Issues with the hot standby heat exchangers and fans in chimneys after desulfurization and denitrification of coke oven gas
Thread Content
After desulfurization and denitrification in the coke oven chimneys, the temperature of the exhaust gases is 160–170 degrees. To maintain a minimum suction force in the flue chimneys, it is planned to heat the air to 120–130 degrees before allowing it to enter the chimneys. With an exhaust gas flow rate of 90,000 cubic meters per hour, what amount of air is required, and what size should the heat exchanger be?
There are significant problems with SCR for desulfurization and denitration
