Protect your boilers and economizers by monitoring their thermal conditions and performance. The unique feature of the G5xxx Series is the dynamic load depen-dent monitoring. Any boiler and economizer behaves differently under different load conditions. Problems that are harmless under low load conditions can become fatal under high load. Here the G5xxx Series gives you adequate and early warnings.
Temperature & Pressure Drop Monitoringfor G50x0 EGEM and G52x0 EGEM light
Soot-fi re accidents in exhaust gas economizers after diesel engines are an increasing problem often caused by low grade fuels, fuel changes, and reduced engine speed. The solution to prevent this problem is simple: Keep the econ-omizer reasonably clean at all times. Our monitors provide your crew with the information to ensure this.
The data on pressure drop and temperatures in compari-son to the current load gives you precise information con-cerning the economizer’s heat exchange conditions. The single parameters vary greatly dependent on the load of the economizer. With this information you are able to de-tect a range of troubles such as soot deposits on the gas side or oil contamination on the water side.
Water Circulation Monitoring for G50x0 EGEM
Suffi cient water circulation is crucial for containing soot burning, which is likely to occur. Soot burning is by itself not enough to cause a major EGE breakdown. It usually dies out due to the cooling eff ect of the boiler water. If however the water circulation is reduced (e.g. due to ex-cessive steam production, steam blockage, pump cavita-tion, scale build up, or the like), the heat transfer is reduced or even lost. This will let soot burning develop into high-temperature fi res and boiler meltdown.
Monitoring the water circulation is therefore the key to preventing fatal failures. The G50x0 EGEM can automati-cally start the stand-by pump.
G55x0 Oil-Fired Boiler Monitor
Key Features G5xxx Series

The G55x0 Oil-Fired Boiler Monitor is designed as a modu-lar system for dynamic monitoring of the boiler’s thermal condition and furnace back-pressure. It measures the fl ue gas temperature and pressure drop across the boiler. This gives a good indication for a range of potential problems:
poor combustion and soot deposits on the gas side;scale build-up or oil contamination on the water side.
With the G55x0 OFB Monitor your crew can maintain its effi ciency with appropriate cleaning, optimize the boiler performance, and save fuel.
Both fl ue gas temperature and pressure drop depend on the actual boiler load. Some boilers have a tempera-ture sensor or even a static pressure drop alarm. But the information derived from these systems is of limited use. Such a static control system cannot detect problems while operating under low and medium load conditions. They are designed not to give false alarms even under high load conditions and thus these control systems only have alarms for a temperature and pressure-drop level that oc-cur under full load.
The G55x0 Oil Fire Boiler Monitor on the contrary will add full value to your boiler control system and a true protec-tion for your boiler as it gives dynamic alarms along with the actual boiler load.
