Wet Flue Gas Desulfurization - Yokogawa

Jul 21, 2020 · Wet flue gas desulfurization or scrubber systems are very effective in reducing sulfur dioxide (SO2) emissions caused by coal combustion boilers. The flue gas discharged from the boiler is fed into the absorber, where a mixture of water and pulverized limestone is sprayed on the flue gas. The

Wet flue gas cleaning and heat recovery - Valmet

There is a lot of energy in flue gas due to the water (30–60%) contained in the fuel and steamed in the boiler. This energy escapes into the environment when the water is not condensed back into a liquid. With Valmet's advanced flue gas condensing technology, you can recover this energy and use it, for example, to increase district heat capacity

Boiler Flue Regulations 2021: A Simple Guide | Skills

Jan 25, 2021 · Energy utilization is an urgent problem to be solved in coal-fired power plants. It is calculated that the heat loss of exhaust gas accounts for 4% to 13% of the total heat loss of boilers, and the water vapor content exceeds 14% in wet desulfurized flue gas from coal-fired boilers, . If the waste heat and water can be recovered from flue gas, the thermal efficiency of coal-fired boiler will be …
