Limestone preparation system in flue gas desulfurization (FGD) consists of following sub-systems: 1. Limestone Handling System. Limestone will be delivered to the limestone storage shed by truck. Limestone will be delivered from the limestone unloading hopper to the limestone day silo by limestone transfer conveyor and bucket elevator. 2.
plant. Coal, ash, and limestone handling systems use bag filters, which act like large vacuum cleaner bags to prevent the release of dust from these processes. Boiler 10 uses a large unit called a baghouse to prevent dust and ash from escaping through the smokestack. In Boiler 11, a fluidized bed

Limestone powder is injected after the coal is burned, typically at the top of the boiler. The sulfur dioxide is formed when the sulfur contained in the coal (it is a contaminant in all coal) burns in the combustion chamber of the boiler. The sulfur dioxide bonds with the limestone to form a particulate; it …
Figure 1 shows the flow diagram for a power plant boiler equipped with a typical limestone slurry system. The three main areas of interest are, (1) SO2 scrubbing module and demister, (2) stack gas reheater, and, (3) materials handling and sludge disposal. Scrubber Module and Demister The function of the scrubbing module is to absorb SO2 from

The modern ash handling systems usually used in large steam power plants are: 1. Belt Conveyor System 2. Pneumatic System 3. Hydraulic System 4. Steam Jet System. 1. Belt Conveyor System: In this system, the ash is made to fall through a water seal over the belt conveyor in order to cool it down and then carried to a dumping site over the belt.
Wet FGD comprises four main processes- flue gas handling, reagent (limestone) handling and preparation, absorber and oxidation, and secondary water and gypsum handling. Wet freshwater FGD uses limestone slurry to remove SOx. The flue gas drawn from the boiler is directed into the absorption tower by a booster fan.
Materials Handling in Thermal Power Plants In a modern thermal power plant, we have motors, generators, pumps,, etc. of various ratings and require a materials handling system to handle these equipment during operation and maintenance. Also a thermal power plant handles large quantities of bulk materials – the largest being coal and ash.

, the flue exhaust gases from a coal-fired power plant are commonly led through a spray of limestone slurry in a so-called scrubber. The resultant reaction typically captures 90% or more of the SO 2. Approximately 80-85% of worldwide FGD units installed in power plants use wet limestone scrubbing vs. other technologies. What happens to the SO 2
FGD SYSTEMS - Limestone FGD Service Provider from Thane. Limestone handling. Large quantity of limestone is used for the Flue Gas Desulphurization (FGD) of coal fired power stations. In case of pulverized coal fired units (PC) in most cases wet FGD technology is used where desulphurization takes place in spraying towers.
Various processes are used for the removal of sulphur oxides (SOx) from thermal power plants (TPPs), such as wet scrubbers, spray dry scrubbers, sorbent injection processes, dry scrubbers, and regenerable processes. The raw materials required and by-products generated include limestone, hydrated lime, calcium oxide, dolomite and ammonia.
