Getting the Design Right for a Reliable CO Mill Fire Monitoring System

Potential coal fires and coal-induced explosions in a coal handling system pose serious safety concerns for any industry that is using pulverized coal. Spontaneous combustion of coal in a coal handling system (coal conveyors, coal mills, coal silos, coal bunkers) has long been recognized as a fire hazard. Coal fires usually start in hotspots when […]

The Requirement for SCR & SNCR

For decades coal has been the fuel of choice for most power stations around the world but also happens to be the most pollutant. The environmental regulation in Europe, China and India has stringent emission limits which coal fired power stations are finding it increasingly difficult and expensive to comply with and are therefore employing […]

TunnelTech 305 Series – Wind Tunnel Test

CODEL International’s new TunnelTech 305 Air Flow Monitor designed exclusively for road and rail tunnel applications builds on years of experience and proven technology. The TunnelTech 305 not only monitors the air flow measurement inside the tunnel it also monitors the direction of the air flow and temperature. This ensures that the tunnel ventilation system […]

GCEM40 Robust, Real-Time In-Situ Analyser – Hot-Wet Raw Gas Measurement for Forward Feed Control

Varying fuel composition in Biomass and Energy from Waste processes makes it difficult to predict the amount of sorbent feed required to effectively neutralise acid and hazardous process gas generated from partial and complete combustion.  Over-dosing means excessive use of expense sorbent material like sodium bicarbonate, whilst under-use may result in breach of emissions limits. […]

Tips on Installing a Tribo-Electric Dust Monitor

There are a number of factors to consider when selecting the position to install a sensor unit. These are listed below, in order of importance: Are there any legal safety constraints that might restricts its location? For indicative monitors this is unlikely, but it is worth checking. The probe must protrude more than halfway into […]

Using a Dust Monitor to Diagnose Potential Problems

Most fabric dust collectors clean their filter bags by injecting a short blast of compressed air down a singe row of bags. This is repeated until every row of bags is cleaned, or until the desired level of differential pressure is achieved. The cleaning sequence is usually by a timer or a differential pressure gauge. […]

How Are Dust Collector Systems Monitored?

Operator Visual Checks Looking at stacks and vents and identifying dust emissions is extremely time consuming, inaccurate and probably too late. When a dust collector starts to leak small amounts of dust, it is impossible to detect with the human eye. If the sky is overcast or it is raining, it becomes even more difficult […]

Dust Monitoring – Choosing the Right Technology

There are several technologies available to monitor dust emitted from collectors. The traditional ones are based on optical systems. However, sensitivity limitations of optical systems have produced an increased use in tribo-electric probes in modern plant. Opacity Monitors These instruments must be used when the required measurement is opacity and are the preferred option for […]

Air Flow Monitors in Tunnels

In most tunnels there are ventilation systems installed of which there are three main types: Longitudinal ventilation Cross ventilation Longitudinal & Cross ventilation   Depending on the conditions and the situations encountered in a tunnel, different air speeds and direction are applied and validated by the anemometer. The measurement of the anemometer is then used […]
