Abstract
Abstract Historically, scale‐up of technologies have been a fundamental driver for successful economies in enhancing performance of applications. In the context of combustion technologies, several scale‐up approaches were developed with the aim of transferring relevant characteristics of combustion systems from laboratory‐ to industrial‐scale system. A reasonable selection of scaling approaches is required to perform a proper scaling of a combustion system. In the current study, the development of scaling methods and their use for technical applications is presented. In order to provide a guideline for the examination of combustion systems to be scaled up, common and recently published scale‐up methods are compared qualitatively, as well as the investigation on scale‐up of combustion chambers, is addressed. Due to the expected further technical and environmental restrictions, the focus of the implementation is directed towards NOx emissions.
