Ikn cooler pdf

This hot clinker dust erode and burn the plates . These are the reasons that make the cooler designers to invent new generation coolers .The stationary inclined grates with control flow aeration and controlled flow air regulators reduced red river problems considerably .In some new generation also coolers the problems still exists. A new control strategy for IKN-type coolers | Request PDF A new control strategy for IKN-type coolers Authors: Antonio Nevado National Distance Education University Ricardo Requena Daniel Viudez The Coanda Wing® technology achieves the purging effect with minimum air flow and improved heat transfer between clinker and cooling air for maximum cooling and recuperation. The resultant clinker bed is characterised by its low resistance to the passage of cooling air.

Formed in 1982 and headquartered in Neustadt, Germany, IKN has subsidiaries in USA, France and India and is well represented in South America the Middle East and Asia. Key guidelines to avoid kiln balls, rings and snowmen are: clinker, sulpho-spurrite rings and kiln balls kiln burner and calciner optim.sed to ensure that there are no reducing conditions as a result of the kiln burner or unburnt carbon >0.1 per cent in the hot meal to avoid poor clinker quality, rings and snowmen.. Created Date This paper presents a new system for the optimized control of IKN-type cement coolers based on adaptive predictive methodology. The new system introduces the concepts of 'layer on grate' and 'thickness of slope', which allow a decoupled multivariable control of the layer of clinker over the grate, and the flow rate of the cooler fans, solving a fundamental control problem for this type 1. CLINKER COOLER 2 CLINKER COOLER Reduce clinker temperature from approx. 1400 o C to approx 100 ~ 200 o C The heat of the incoming clinker is recuperated in the secondary air of Kiln An efficiency of incoming clinker heat usually lies within 65 ~ 75% 3 Clinker Cooler Type 1.

The increasing size of the kilns and the push for minimum energy consumption led to a major reassessment of cooler design. The "modern" grate begins with the IKN patents of 1983. The essential characteristics progressively incorporated into new coolers If all the 250 MTPA clinker produced is cooled by IKN coolers (based on savings of power by 1.5 kWh/t on average) YOU can supply free power for 9 months for a city like Jodhpur Conclusion .
