Water spray will freeze preventing cold weather operation. Nozzles tend to plug due to the higher pressure drop at the nozzle discharge making solids come out of suspension at the nozzle tip. Water Sprays create a BTU penalty to materials used for fule such as coal or biomass adding to the cost of power generation adding as much as 5% moisture ...
Water spray pump stations. Hauhinco water spray systems are developed to supply shearer water sprays or the coal plow operations and the cooling systems of the drive motors. The systems consist of EHP-3K plunger pumps with an electric motor, a water tank, a filter unit, as well as the necessary piping.
The water and steam get squeezed along with increase of water-feed flow, so the more steam is pushed into turbine to work, and the unit load increases. As the coal-feed rate and total air flow are unchanged, the unit load gradually declines to the original level. When the water-feed flow increases, the steam pressure increases and then decreases.
Cooling & Spray Water System. Necessary cooling water pipelines will be provided for cooling water requirements in dome valves and for quenching of mill rejects in pyrite hopper, whenever the temperature of the pyrite hopper exceeds desired levels. Service Water will be used for Quenching & Dome Cooling purpose.

Premature failure of critical machinery underground is also associated with exposure to a significant build up of coal dust. Our high flow, low pressure water systems provide the perfect solution to reduce air-borne coal dust by supplying clear spray water to the shearer, the coal plow and to drive motor cooling systems.
New water spray system reduces dust in coal mines. CARBONDALE, Ill. -- In an underground coal mine, dust is the miner's enemy. Particles too small to see work their way into the respiratory system, where they can accumulate and cause health problems such as pneumoconiosis or black lung in later years. Larger particles obscure visibility while ...

We can make full use of the surface strengthening cooling and heat dissipation of the grinding system, such as spraying atomized water into the outer wall of the flour separator and making a flume along the outer side of the screw conveyor. It is also feasible to spray water from the grinding head or tail when the ball mill is working, but only ...
Deluge water spray systems are commonly used in the protection of such machines. Coal is transported on encased conveyor belts that run across coal processing stations. Fire detection and medium velocity automatic deluge water spray systems are most suitable for protection of coal conveyor belts.
Water spray systems: Area-wide spray Fires start very quickly in rolling mills, coal conveyors and hydraulic systems because fuels and lubricants are subjected to high temperatures. Protection is provided by water spray extinguishing systems.

The water required for the system is supply by feed water pump. Wetting agent, which is in liquid condition, is dosed by metering pump as per requirement. SPRAY HEADERS WITH PIPE LINES PUMPING SYSTEM includes solution pumps, isolating valves, spray nozzles, and pipe lines. The solution pumps are used to supply pressurized water to spray headers.
The first stage of quenching begins when the hot rolled bar leaves the final mill stand and is rapidly quenched by special water spray system. This converts the surface layer of the bar to a hardened structure called 'Martensite' while the core remains austenitic.
After ventilation, the use of water sprays is one of the principal means of control- ling airborne respirable dust in coal min- ing operations. Water sprays have been initially reported to reduce airborne res- pirable dust from 20% to 60% by Kobrick (1969). A U.S. Bureau of Mines labora-
pumping system includes solution pumps, isolating valves, spray nozzles, and pipe lines. The solution pumps are used to supply pressurized water to spray headers. The required quantities of nozzles are used to spray water. Control units with electrical systems consists of sensing units, control panels. Coal flow is sensed by sensor.
