Improved control - reduced operating costs

Burner control systems with mechanical fuel-air compound control have a sturdy design and long service life. In some cases, however, they are too inflexible for today's demands. Because all the actuators of the burner are connected to each other mechanically, this type of control system is prone to a series of disadvantages that result in higher fuel consumption levels due to system constraints. Retrofitting an electronic compound control system at this point reduces consumption and ongoing costs, also producing further advantages at the same time. Modernization increases convenience and control accuracy and helps to optimize control response, especially for multi-fuel burners.

With an electronic compound control, each actuator has its own servomotor that can be moved completely independently of all the others. This makes it possible to adjust air and fuel quantities at different ratios, for example, depending on whether light oil, heavy oil or gas will be used for combustion. This freedom to make precise settings cannot be implemented with mechanical compound control and represents the decisive advantage of electronic compound control. Concentrations of oxygen (O2) or carbon monoxide (CO) are also recorded and can be included in processing to optimize process control: This makes it possible to minimize air excess and increase efficiency significantly.

With seavis compact and seavis pro, SAACKE provides electronic burner control systems for all applications. They are modularly designed, simple to expand and very easy to integrate into higher-level process control systems. Retrofitting with these systems not only significantly improves combustion quality but also the efficiency of the entire plant. Graphical preparation of operating data provides a detailed view of the operating profile while the extensive archive of fault messages reduces costs of maintenance and downtime.

seavis also makes it possible to control firing systems with multiple fuels and air flows, including in parallel as simultaneous firing, thereby providing solution that extend well beyond the limits of mechanical compound control systems. In summary, retrofitting as described here not only increases the efficiency and control quality of the combustion process, it also pays for itself faster than would be imagined.
