The best solution for clogging detection under the cooler grates
The Microwave Pulse Sender-Receiver System consists of two electrically isolated units: the sender and the receiver unit. The sender emits a burst of microwave energy towards the receiver, which is designed around a tuned microwave detector. This burst of energy is transmitted approximately 200 times each second. While the line-of- sight between the sender and receiver is clear, the receiver will detect each of these bursts. If the line-of-sight is interrupted by a sufficiently reflective or absorbent material the receiver will not detect the transmission and therefore the contact is activated.
This system is suitable for difficult applications such as high temperature or/and abrasive products like clinker with big granular size. The microwave solution is the best alternative to the technology currently used which is the nucleonic switch. Just like the nucleonic switch they are of non-contact type (ex. Level detection of a chamber in a cooler) but coupled to a robust mounting system and with accessories such as extension pipes and ‘vitroceram’ glasses fit for high temperature. The primary advantage vis--vis the nucleonic switch is that the microwave technology is safe for humans and no administrative documents are required.
Sometimes problems can occur in a cooler like a breakage of the grate plate or a fault on the double flaps at the discharge of the chambers above the drag chain. Many solutions for this problem already exist such as high temperature capacitive detector, nucleonic switches, temperature or pressure measurements. Most of these solutions need direct contact with the inside of the chamber thus requiring substantial maintenance.
The micro wave solution has many advantages:
• Detection of the build up along the entire width of the chamber resulting in better accuracy.
• No maintenance required due to non contact with the material.
• Very high longevity of the sensors.
As an example, our first installation was in Lafarge Cement plant in Le Havre (France) in 1993 and has been working efficiently since then with the same system and no maintenance operation. ITECA SOCADEI has therefore more than 12 years of experience in this field and has among its clients many cement plants all over the world as well as cooler manufacturers. ITECA SOCADEI can deliver for you the twin advantages of reliability (non contact) and safety (no gamma rays).
This system proved to be successful in other applications for clogging and level detection such as : in cooling towers, primary crushers, raw material balls mill’s infeed, hoppers under filters or ESPs, big-bag filling, etc.
