The utility model discloses a waste heat recovery system of desulfurization flue gas applied to coal-fired power generating sets, which comprises at least one gas and water heat exchanger used for
In addition, it will be more appropriate to use this process when the desulfurized flue gas temperature is relatively high (5560 °C). Desulfurized flue gas corrosion coupled with deposits in a Feb 01, 2018 · At the testing position, the desulfurized flue gas temperature was 49 ± 1.5 °C, and the flow velocity was 11 ± 1.5 m/s (depending on the boiler load). The flue gas was saturated with water vapour. In practice, the temperature of the hot water in the heat exchanger tubes of the flue gas reheater is between 50 and 100 °C.
The original temperature of desulfurized flue gas was ranged from 40 °C to 55 °C, and the temperature drop of desulfurized flue gas in the condensing heat exchanger was changed from 2 °C to 10 °C. The ideal supersaturated degree and condensable vapor amount at different conditions are shown in Fig. 3. Heterogeneous Condensation for Abatement of Sulfuric Acid
high temperature heat exchangers (HTHE). Initially HTHEs were developed in ceramic material for gas turbine engine recuperation, high pressure air heating and flue gas recuperation. Recent application areas are found in hydrogen production, high temperature fuel cell Improving the removal of fine particulate matter based on Jun 01, 2018 · Desulfurized flue gas temperature:40 °C60 °C (interval 2) Desulfurized flue gas relative humidity:90%100% (interval 5) Desulfurized flue gas temperature drop:110 °C (interval 2)
Jan 25, 2021 · First, a higher solution temperature increases the average temperature of the heat source in the heat exchanger, thereby increasing both the fuel exergy and product exergy. Second, a higher solution temperature increases the outlet flue gas temperature, so the product exergy and exergy efficiency of the absorber increase. Flue gas and condensing heat exchangers from BoschThe flue gas flows at the boiler outlet inherently have heat potential at a high temperature level. A flue gas heat exchanger is great to use in order to prevent unnecessary flue gas losses. This efficiency component extracts heat from the hot flue gas
