查询词典 limestone

CFB (Circulaiing Flued-bed Boiler), which could desulphurize by adding the lime stone in boiler, was adopted in the project of petroleum coke taking the place of oil; IGCC was adopted in coal to gas project; PC+FGD, such as limestone/plaster wet type desulfurization, liquid spray flue gas desulfurization, electron beam flue gas desulfurization and sprayed dry type desulfurization etc., was adopted in the other projects of thermoelectricity. Desulfurization inside boiler needs less running expenses but high investment and lower desulfurization efficiency.
