► The energy and exergy efficiencies of the base case clinker cooler are % and %, respectively. ► To increase 5% mass flow of cooling air, the energy and exergy efficiency increase % and %, respectively. ► Increase of grate speed and cooling air temperature cause to increase of all efficiencies.
Castor cooler is an important main equipment of clinker firing system in cement plant. It is responsible for cooling, heat recovery, transportation, crushing and other functions of high temperature red hot clinker (about 1400 ℃). In the pr
Feb 23, 2016· Cooling fans: Cement industry uses large number of cooling fans usually between 5 to 15 in one clinker line based on the kiln capacity. Cooling fans are used to blow cold air to the cooler and to cool the clinker from 1500oC to 100oC.
The amounts of different components vary depending on the desired properties of the produced clinker. Thermochemistry of Clinker. The raw materials entered into the kiln are taken at room temperature. Inside the kiln, the temperature continues to rise and when it reaches its peak, clinker is .
Jan 22, 2016· Cooler Exhaust Fans. Cooler exhaust fans move ton of exhaust air per 1 ton of clinker production. This process is a part of air blown into the cooler by cooling fans that are not useful for fuel combustion. In addition to these key process fans, cement industry also has many nonprocess fans.
Clinker Cooler After cement is dried by being put through a rotary kiln and converted to clinker, it needs to be cooled. Cooling tunnels are used to reduce the temperature of the clinker from over 2000°F to .
clinker cooling technology The FL® CrossBar® cooler represents the latest evolution in clinker cooling technology. It is based on proven and refined FL cooler technology. The result is a cooler representing the highest standard in clinker cooling technology at an attractive investment level. Key benefits No Snowman formation
subsequent calculation was based on the principle of input (clinker, cooling air, fuel, water injection) and output (clinker temperature, secondary and tertiary Air, excess air and cooler radiation) of clinker from the grate cooler. Cooler Input The cooler clinker input is .
Nov 04, 2014· Clinker cooler's efficiency. 1. From Clinker Cooler Clinker Temp. 1400oC Reduces To 100 .. 200oC. 2. Cooler Thermal Efficiency: * 100 h = A B A Notation: A = Heat content of clinker leaving the kiln B = Heat losses of clinker cooler B consists of = Heat loss in cooler exit air Heat loss in clinker leaving cooler a = Heat loss by radiation b = c =.
Feb 21, 2013· A cooling grate, for cooling and transporting of cement clinker having at least one grate element with at least one support for cement clinker, having at least one cooling air channel discharging into the support which is inclined in conveying direction at least in a section adjacent to its outlet used to inject cooling air into the clinker has improved cooling characteristics if the cooling ...
degrees to clinker after passing through various phases. The cooler is meant for cooling hot clinker which is discharged from with 1100 to 150 degree centigrade by centrifugal fans. Ambient air is pumped into cooler through fans at bottom side of grate pass through hot clinker bed. Fly ash is added to clinker as per required percentage
The cooling of the cement clinker discharged from a kiln, which is illustrative of one application of this invention, is usually accomplished by conducting the mass of hot clinker in heat exchanging relation with respect to a suitable cooling fluid such as air.
Clinker cooler. Competitive clinker production and cooling is essential to cement producers over the world. Now there is a next generation clinker cooling system that will give producers an edge over the competition. A next generation clinker cooling system redesigned for better efficiency and .
Industrial Clinker Cooler is extensively used to cool the clinker and extracted heat from hot clinker is supplied at secondary and tertiary air to kiln. Acknowledged for its optimum specific grate load, this ensures lower heat consumption.
without material in April 2015. The first clinker was cooled only a few days later. Operation of the ETA cooler At a specific load of t/dm² and Nm³/kg cooling air, a cold clinker temperature of 65˚C above ambient temperature is achieved. The intensive cooling of the clinker is realised by a long retention time inside the cooler.
Cold clinker discharge temperatures are maintained with the lowest air loading per kg of clinker. The main features of the clinker cooler with Coanda Wing® grate plates are: Excellent clinker distribution resulting in uniform, efficient cooling of the clinker across the full .
This new cooler combines the best solutions for each of the two fundamental, mutually interacting functions a clinker cooler has to accomplish: Clinker conveying is based on the "moving floor" principle; Aeration is controlled by selfregulating valves
Dec 11, 2018· It is normally caused by cooling of the clinker by the secondary air as it falls over the nose ring at the outlet of kiln into the cooler. Also sometimes by clinker dust being carried back into the kiln from the cooler in the secondary air. • Back to Top Q: why and how coatin is formed in cement kiln burning zone why and how coating formation in kiln A:
For the cement clinker, a macroporous unconsolidated porous medium, seepage heat transfer theory can more accurately reveal its internal problems. Because of the macroporous characteristics of the cement clinker accumulation body, the changes in the physical properties of the surrounding air, such as viscosity, density, and so on must be taken into consideration in the cooling process of the cement .
