Limestone Mill For Desulfurization Of Flue Gases

Desulfurization Of Glue Gas
The flue gas desulfurization (FGD) plant removes sulfur dioxides (SO2) from flue gas produced by boilers, furnaces, and other sources. More than ninety percent of U.S. flue gas desulfurization (FGD) system capacity uses lime or limestone.

Limestone Desulfurization Mill
Mill is a new generation of milling equipment with the world’s advanced level. The equipment adopts many world advanced technologies such as bevel gear overall transmission, internal thin oil lubrication system, oil temperature online measurement, etc. It has a number of independent patent technology rights, has a small footprint, low comprehensive investment, low operating cost, high efficiency, and environmental protection.

The overall process is simple and the degree of automation is high; the entire system operates under negative pressure, and the dust does not overflow to ensure cleanliness; at the same time, the chemical composition of the finished product is stable, the particle gradation is uniform, and the fineness of the product is adjustable, which can fully desulfurize the flue gas. The suitable limestone powder needed to improve the desulfurization efficiency.

Limestone Desulfurization Process Stages
Absorbent preparation and dosing
Removal of SOx (HCl, HF)
Dewatering and conditioning of the product
In this method, limestone (CaCO3) or quicklime (CaO) can be used as the absorbent. The selection of an additive which can be added dry or as a slurry is made on the basis of project-specific boundary conditions. Choose a limestone mill is important.
