Cooling Spray. Coke used for blast furnaces in a steel mill is produced in a coke battery. After the coke is processed, the coke "clinker" is pushed out of the coke oven into a railroad car or "quench car" and cooled with large amounts of water down to 150-200ºC (300-400ºF). It …
Water at low pressure is mixed with compressed air directly in the nozzle. In comparison with the Spillback, this system is more efficient and produces smaller water particles. That reduces the required gas retention time in the tower, then its size. Our Expertise Gas Cooling systems: Clinker Cooler gas and material cooling water spray system
Following capacity increases, cooling with air alone is often no longer sufficient to achieve the proper operating conditions of the downstream filter. Injecting water into the clinker cooler provides a remedy here. The cooling of the gas also causes the gas volume to reduce and protects downstream plant components from excessive gas temperatures.
Lechler offers gas cooling systems for various applications that can be individually adapted to customers' requirements. Best results are achieved in gas cooling processes only when detailed knowledge of the process-specific requirements is available to assist in the choice of nozzles.

Misting Cooling System widely apply for garden, Trampoline water park, landscaping, greenhouse, humidification,outdoor cooling system, deodorant air purification, Swimming pool misting fogcooling, Mist mosquito system and so on. So transform your hot patio into a refreshing escape from the heat with a misting outdoor cooling system.
To maintain overall plant capacity, your cooler must handle a constant throughput of clinker. Problems with the cooler can result in an unstable kiln, damage equipment, and influence the clinker quality. And excessive wear of cooler parts can lead to inefficient cooling processes and even production stoppages.
evaporative gas cooling / atospray™ system Cooling a hot gas stream by direct injection of water, which completely evaporates to cool. This system can be suitable for several industral processes, such as: incinerators, kilns, furnaces, in a wide range of applications:
• [15] API 2510 specifies the requirement for waterspray systems as follows:- ¾ Fixed water spray systems shall be designed to protect against pool fire exposure to the vessel with a minimum fire water application rate of 0.10 US gallons [US] (4.1litres) per minute per square metre.
Clinker Cooler Emergency Water Spray System Feb 2013 - Mar 2013. A clinker cooling system is critical safety control in a cement plant, required to control the temperature of clinker (a material ...

Gas Cooling and Conditioning. Poor control of gas temperature, volume and / or humidity often results in excessive emission levels, downtime due to ESP overload, reduced efficiency of damage to downstream equipment, wetting and sludge build-up, and increased energy costs. Depend on Spraying Systems Co. for the process expertise you need to ...
Cooling air requirement is generally designed at 2.2-2.5 nm3/kg-clinker. Either hammer crusher or roller crusher is used to break lumps of clinker before coming out from cooler. Water spray or Air to Air heat exchanger is used to cool down cooler vent air before de-dusting in ESP or bag filter.
Cooling Solids. Efficient methods for cooling solids can impact efficiency throughout the process. Depend on Spraying Systems Co. for a broad line of nozzles and headers designed for optimizing this operation in any industry. Our full cone, rectangular spray, oval spray and flat spray nozzles provide uniform coverage over a wide range of flow ...
The Differences Between Types of Water Systems. A spray system effectively suppresses dust and odor in certain commercial and industrial applications. A spray stream product produces a column of air that projects a dense spray of atomized water. The water can travel distances of 150 feet or more, and are engineered for industrial applications.

Injecting water into the clinker cooler provides a remedy here. The cooling of the gas also causes the gas volume to reduce and protects downstream plant components from excessive gas temperatures. This reduces operating costs and avoids additional investment costs for a larger filter.
The injection takes place at the rear part of the clinker cooler, immediately upstream of the gas outlet. Depending on the space above the clinker cooler, the nozzles can be attached both on the top and the side. We usually offer spillback nozzles for controllability. In comparrison to conventional single-fluid nozzles, spillback nozzles ensure ...
During upset clinker cooler operating conditions, the Air-to-Air Heat Exchanger aids in the protection of the downstream equipment within the specified design temperature limits. This is accomplished without introduction of dilution air or water spray systems.
PRINCIPLE OF OPERATION. In VEL Grate Cooler Water Spray System, the temperature of the stream of gas / clinker is cooled in three stages: 1) Heating of the injected liquid to the boiling point temperature corresponding to the system pressure.
