Tiivistelmä
Bubbling fluidized bed boilers are applications that are utilized in the energy industry sector. Commonly, these applications are used to produce steam, heat or electricity. Steam powers many other industrial processes that produce goods and services.
Thesis studies the concept of maintenance and boiler performance features from the view of equipment, maintenance project team, plant owner and notified bodies. The results of the literary section summarize the features that are involved in the development process to achieve a safe and reliable plant environment.
The study presents the most common characteristics of biomass utilizing BFB applications, including fouling and typical wear mechanisms. The study focuses on the boiler’s most essential internal structures, environmental aspects and the legal requirements that are reviewed to the boiler repair and maintenance work. Maintenance work is usually performed by specialized and qualified workers during the planned boiler shutdown.
The contents were mainly compiled by studying the literature of the field, by interviewing Andritz Oy’s engineers and by reviewing the archives from Andritz Oy’s database. It was possible to utilize Andritz Oy’s extensive maintenance instruction databank and published technical studies of BFB boilers’ repair works. Over 40 inspection reports were reviewed in the research process.
Maintenance scheduling and resource planning was the assignment of Andritz Oy’s Power Boiler Service department. The plan is eventually an attachment that is left out of public version, but which is still a significant part of the entirety. The task was to create a platform for managing the shutdown related tasks. This gives an opportunity to manage and analyze the project workloads. The schedule and resource plan platform will be developed in the future to cover also case company’s alternate and residue fuel boiler applications.
