Wherever water is used for DUST SUPPRESSION in

Mines / CHP / Power / Steel / Cement

‘hmc Conflow’ products can be found’The main areas of use is :-1. Dust Suppression2. Fire Fighting

Dust Suppression

• Why needed:- airborne coal dust, when mixed with gas / air in the presence of a nakedflame, is very dangerous and can causes an explosion.

- DUST is a health hazard- Supress dust to prevent it becoming airborne

• What is needed: Essential Dust Suppression RequirementsWater supply available in the plants / CHP to suppress the DUST

FILTRATION-PUMPS-REGULATOR-PIPELINE-SPRAYBARS-NOZZLESPRAY ACTIVATION (manual / auto ) (mechanical / electrical)CONTROL PANEL (DOL – VFD) / Auto mode selection

• Where located:– Primary unloading (wagon tippler / Track Hopper / Truck unloading)– Conveyor belt transfer points– Stock Piles

Dust Suppression System Fundamentals

Dust prevention – Humidity/moisture content in the material is increased to prevent dust from becoming airborne

Dust suppression – Humidity/moisture content in the material is added to the air to capture dust particles that are already airborne

Dust returned to the product stream with correct wetting to minimise any product problems

Poor quality water can be minimised by filtration to reduce water contamination

Water conservation is controlled by the system being activated only when conveyors are running under load conditions

Dust Suppression System Standard Practice

Using a minimal amount of water

Amount of moisture added to percent of material weight

Water spray requires a high volume of moisture for dust suppressionThe addition of moisture can be costlyPlain water added at 5% of the material weight requires 27,852 –139,260 kj of energy to dry the product to acceptable levelFine spray added at 0.1% of the material weight requires 279-1393 kj of energy to dry the product to acceptable level The use of fine & controlled dust spraying systems reduces the likelihood of a thermal penalty being imposed on coal operators

Dust Suppression System Standard PracticeSpray points at the chute and on the belt runSpray patterns designed to not directly infringe

upon any surfaceSprays mounted in order to minimise the

exposure to a heavy laden dust air stream. This avoids erosion of spray nozzle componentsSpray patterns generated so all fugitive

emissions are forced to pass through the fine spray blanket

STOCKPILE DS SYSTEM (SPDS)

Sprinkler Features

Roadway & Stock Pile Dust Suppression for overburden haulageroadway & Coal stockyards has become a necessity in mining/power project across the world.

Sprinkler dust suppression system is actually spraying waterpumped through a long pipe work giving an effect of natural rainfallrequired in a particular area with the help of Sprinklers / RAINGUNSavailable in various discharge capacity & throw angles.

System prevents liftoff of dust from stockpiles and roadways.Water spray over the stock-pile area is produced by sufficientnumber of sprinklers suitably installed in a ring to cover the entireprojected area of the stock pile / roads.

The Sprinklers are swiveling type with the provision of change inthe swiveling angle & height, as well as spray nozzle angle. (Variousmodel available) The sprinklers break up the water into smalldroplets simulating natural rainfall.

Eagle Sprinklers

Raingun ES-65 PC Sprinkler:ES-65 PC Raingun of impulse drive type have 2½” inch BSP femalethreaded connection, housing made from die cast all alloy to IS-617GR-4652, blade: cast steel to IS 1030 ideally suitable for dustsuppression applications.Raingun are free from Ball Bearing, Gear or Cam and free fromperiodic maintenance requirements such as oiling, greasing,alignment and / or replacements. Raingun must have a radius rangeof 42 meters and flow range from 3.8 LPS with 2.0 to 4.5 kg/cm2operating pressure respectively.

Twin 95 Sprinklers

Raingun Twin 95P Sprinkler:Twin Raingun 95 P of impulse drive type have 2 inch BSP femalethreaded connection, housing made from wear resistant castaluminum, ideally suitable for dust suppression applications.Raingun are free from Ball Bearing, Gear or Cam and free fromperiodic maintenance requirements such as oiling, greasing,alignment and / or replacements. Raingun must have a radius rangeof 27 to 54 meters and flow range from 2.6 LPS to 15.6 LPS with 2.0to 6.5 kg/cm2 operating pressure respectively.
