When it comes to boiler control, selecting the right types of valve actuators and positioners is key to ensuring safe, efficient and reliable performance whilst also minimizing environmental impact through reduced emissions. Naas deJager, Global Product Manager for ABB’s actuator and positioner products, looks at some of the key challenges that can arise in boiler control applications and how they can be solved by choosing the right actuator for the job.
The growing awareness of the impact of human activities on the environment, coupled with initiatives such as the Paris Agreement and tightening legislation, is putting industrial companies under growing pressure to find ways to minimize their emissions.
For companies that rely on combustion-based processes, there is a need to ensure that the right conditions are achieved for optimum efficiency. Combustion optimization has become an absolute necessity for maximizing performance and efficiency as well as reducing environmental impact and increasing time between maintenance shutdowns.
However, maintaining optimum conditions can be difficult, with challenges including rapid changes in process conditions, variations in fuel quality and the impact of plant shutdowns and start-ups all needing to be handled by the final elements used to control combustion plants
Widely used throughout many power plants to provide precise and continuous positioning of the final control elements used to control flows of air and other variables, actuators and positioners can make a big difference to combustion performance.
The following is a look at some of the key applications in power plants where using high performance actuators and positioners can help ensure the highest levels of boiler control.
