New Coal Fire Detection system

CODEL International (UK) has recently introduced a new Coal Fire Detection System into the marketplace. The early detection of coal fires in coal handling systems on coal fired power stations is essential to prevent catastrophic damage to expensive plant and serious injury to personnel. The most reliable and accurate method of detecting coal fires or smouldering is to monitor the carbon monoxide levels within coal handling plant areas such as silos and mills and detect rapid increases in concentration of the gas.

The CODEL Coal Fire Detection System is designed for use on:- Coal silos, Coal mills, Coal bunkers, Grinding plants; Coal bag houses and Coal conveyors.

The system features a rugged, infra-red cross- correlation analyser capable of measuring rapid changes in CO concentration accurately with the minimum of maintenance required. The analyser can be re-calibrated automatically using integral valves to ensure ongoing drift free performance.

The CODEL CO monitor samples the gas content of the critical area through a non-intrusive steel sintered filter mounted in the wall of the mill outlet duct or hopper. This removes the need for intrusive sampling probes which are prone to wear and are expensive to replace. Furthermore, the filter is back flushed with compressed air at regular intervals to ensure an uninterrupted flow of sample gas and to minimise maintenance.

Extensive field trials of the Coal Fire Detection System in the UK, Poland and China have shown this new monitor to be extremely reliable, accurate and to require minimal maintenance.
