ABOUT: The Client is a leading North American paper manufacturer headquartered in Spring Grove, Pennsylvania. With over 150 years of leadership, their manufacturing facilities mark the birthplace of modern papermaking.
The Client had severe issues with the installation of their 6 and 7 Power Boilers and requested engineering services to address these problems. The existing PB6 and PB7 combustion air systems had significant design issues and their Low NOx burner systems were not adequate for the boiler systems. Additionally, the existing PB6 and PB7 super heater sections suffered from heat affected areas due to repeated refractory failures. The original designer and installer of the system attempted to make corrections to the design several times but failed to make adequate corrections to the system. TAI corrected the poor design and installation attempted by prior engineers.
Significant vibration of the floor in the boiler building occurred as a result of the original installation configurations from the fans. The Client’s goal was to increase reliability and minimize issues and provide a stable system between required maintenance.
TAI supplied a Senior Project Manager who was experienced with process mechanical power-related projects and was responsible for the project scope, schedule, budget, quality of documentation and the construction support.
TAI engineered several solutions to this project, including:
TAI supported this project by providing comprehensive project management, engineering, and design for the development of detailed design documents. Our mutli-disciplinary team achieved success working on the stress and structural aspects of the Superheater and the FD fan foundation re-design, eliminating the vibrations from the FD fans on the fan deck. The deformation and “hot spots” on the superheaters and vibrations of the floor in the boiler house building were essentially eliminated due to the modifications that were performed. Modifications and installations were made on time. The Client reports that the systems have been operating normally since TAI’s modification designs and recommendations were implemented.
