SBS5100 Exhaust Gas Economizer Monitor

How to Avoid Soot Fire Accidents

Soot fire accidents in exhaust gas economizers after diesel engines are an increasing problem. Soot burning can develop into very high temperature fires and eventually result in serious damage in the form of boiler meltdown.

Many boilers have temperature sensors or even a static pressure drop alarm. However, a static control system cannot detect problems while operating under low and medium engine load conditions.

So how do you avoid soot fire accidents? The answer is simple: “Keep the economizer clean and ensure water circulation at all times”.

Dynamic Load Depending Monitoring

SBS5100 Exhaust Gas Economizer Monitor offers a unique solution that will provide you with dynamic monitoring of different parameters in relation to engine load including pressure drop, inlet and outlet temperature. Monitoring the water circulation flow is optional.

Monitoring these parameters along with actual engine load will indicate soot contamination and the best time for cleaning, thus helping to maintain high efficiency of the economizer and avoid economizer breakdown.

How to Avoid Boiler Breakdown

In oil fired boilers, thermal stress on the boiler tubes is a critical problem. The problem usually arises due to scale build-up or oil contamination on the water side of the tubes and soot contamination on the gas side, which will reduce the heat transfer efficiency.

In some extreme situation, it can lead to high cost damages since insufficient water, problem in water circulation, contamination and asymmetrical heat distribution may cause the boiler to break down.

Dynamic Boiler Monitoring

The SBS5500 OFBM offers a dynamic monitoring of flue gas temperature, pressure drop across the boiler and boiler pressure in relation to the boiler load. The monitor gives alarms to a certain level of soot contamination, scale buildup or contamination. With this, your crew can maintain boiler efficiency with appropriate cleaning, optimize boiler performance and avoid critical problems.

In connection with fuel saving, please note that the system can be extended with our SBS3600 Stack Gas Oxygen Analyzer for optimum fuel/air combustion trim.
