Boiler plants
Control emissions. Optimise boiler settings.
Whether as water tube boilers, shell boilers, for thermal output air cleaning or for marine boiler systems: anyone who installs a boiler nowadays can resort to technologies which consume far less energy and pollute the environment less than was the case 15 years ago. Nevertheless, the combustion technology on industrial burners with a service life of 30 to 40 years has to be updated two to three times on average. Because the statutory emissions limit values are getting more and more strict, especially for NOx. For this reason, emissions values are determined on boilers and burners during commissioning, maintenance and for high-precision emissions measurements (e.g. as preparation for an official measurement).
The cost-effectiveness of the system and the setting of the burner can be clearly assessed on this basis. In addition, it is ensured that the system complies with the legally established maximum values for flue gas loss and emissions.
Ensuring the efficiency of boiler plants
When analyzing the burner’s behaviour, the focus of attention is often on fuel supply, atomization, control behaviour and emissions values.
But experienced service technicians know:
For a wide control range, stable combustion and best emission values, the optimal supply of air is crucial.
Therefore, it must be ensured that fans, air ducts and controls are coordinated with each other.
So for every combustion process there is an optimal ratio of fuel and air supply. In this area, the combustion plant operates with a stable flame, the best efficiency and the lowest emissions. The challenge for the service technician is to determine the optimum air ratio and adjust the system accordingly.
How the changes to the fuel-air mixture can be optimally adjusted in detail varies depending on the boiler manufacturer, fuel type and control scheme. Some burners control the amount of air introduced into the boiler, others the amount of fuel and still others allow both parameters to be set. In any case, it is important to know the exact amount of oxygen in the process for safe and economical operation.
