COAL CONVEYOR PROTECTION
TM INTRODUCTION * If a smoldering coal or embers are introduced due to spontaneous combustion onto a conveyor during a loading and unloading operation, it is every possibility to be conveyed to a transfer point, crusher or silo or bunker. * At such places hot coal may ignite combustible dust accumulations and may lead to large scale Fire incident. * Critical Equipment losses, production loss, property loss, loss of human life are need not to be elaborated. * Coal Conveyer Fire Protection is very much essential and important.

COAL PRODUCES EMBER AT ITS EARLIEST STAGE. EMBER√ VERY EFFECTIVE AS IT CAN DETECT THE COAL FIRE AT ITS EARLIEST STAGE AND ALSO WHILE THE COAL EMBER IS MOVING ON THE CONVEYOR
IH 153E – Infra Red Ember Detector TM
BASIC CONCEPT Infra Red Ember Detector are used to detect hot moving spots on the conveyor before they reach processing machinery or storage hoppers and initiate alarm and Fire Extinguishing arrangement. PRINCIPLE OF DETECTION Hot Carbon Dioxide and Carbon Monoxide produced by the Coal Ember is emitting Infra Red radiation. IR Sensor in the Detector responds when the Ember enters the sensor filed of view.
TM PRODUCT INTRODUCTION Agni Controls is pioneer in IR Technology. Our IR Spark & Ember are widely used in Machinery Protection especially in Textile Industries for last 18 years. More than 5000 Nos. of IR Spark/Ember Detectors are in operation. fladet - IH153E Infra Red Ember Detectors are specially designed to detect moving ember with 90 Deg. Cone view. Detector is designed with four independent Infra Red Sensors and special electronic logic analysis is used to give the best result. IH 153E IR Detector with IP 67 protection is well suitable for dusty environments.
TM IH – 153E fladet IH 153E IR Detector with unique features makes the detector user friendly and least maintenance requirement. Flashing Green LED indicates healthiness of the Detector 4 wire system 2 wire for Input Supply and 2 wire suitable to connect any Standard Fire Alarm Zone / PLC/ Annunciation. No Separate Control Panel is required. Any Annunciation or PLC or fire Alarm Panel can be used. Air Purging provision makes cleaning very simple. By connecting existing instrument air, the Glass surface can be cleaned either by simple manual method or by automatic arrangement as per site requirement. Dedicated separate air source also can be incorporated. IH 323 Air Purging Unit is Stand Alone Provided with Air Blower operated on 230 V AC.
TM IH – 153E The Detector is cost effective because of the above referred flexibility. Simple mounting bracket with tilting arrangement is used to easy field erection and maintenance Spectral Filter is nm. Because of the critical spectral range it is ineffective to sunlight, other lights. Cone of Vision is 90 Deg. which makes wider coverage. Wider Range of operating Temperature (-40Deg.C to 60 Deg. C) and Input supply voltage 24 V DC+/-20% ensure proper detection performance. Non ferrous Rugged enclosure suitable for dusty and windy environment with IP 67 protection.
TM DETECTOR POSITION ๏ Detector should be mounted on the conveyor hood or gantry structure looking down at the coal being transparent. ๏ Detector will detect 100 Sq. cm glowing coal ember at the distance of 3 ft. ๏ Detector cone of angle is 90 Deg. across the belt. It is recommend to mount the Detector at a height equal to half width of the conveyor. ๏ For increased sensitivity two Detectors are recommended if the width is more than 2 meters. ๏ It is recommended to a minimum of two Infrared Ember Detector for each conveyor. ๏ In normal practice close to the tail pulley one set of Detectors and close to Head pulley, another set of Detectors may be located. ๏ These detectors shall be wired as separate zone in the control panel.
