biomass steam boiler flue regulations

Jun 01, 2019 · With the help of the flue gas cooler and air preheaters, the flue gas is finally discharged from the CFB boiler with the acceptable temperature such as ∼129 °C, and the flue gas temperature in the whole S CO 2 CFB boiler shows a very similar distribution to that in the typical water steam CFB boiler, as shown in Fig. 10, which could guarantee the reasonable boiler efficiency. However, it is clear that the benefit of residual flue gas …

Dry FGD By-Product Characteristics and Utilization

Polishing Unit of CFB Boiler In circulating fluidized-bed (CFB) boiler, limestone (CaCO 3) is injected at 850 – 950 o C to form lime (CaO) and reacts with sulfur dioxide in flue gas to form anhydrite (CaSO 4) for desulfurization. By-Products generated from CFB boilers are mainly composed of CaSO 4, un-reacted CaO and residual coal ash.
