Abstract
The assessment of the technical condition of the structure in industrial facilities is sometimes very difficult, even for experienced construction specialists. First, this applies to facilities in which there are quite specific cubature constructions, as objects located in the coal mine facility, or coal-fired CHP plants. In the case of energy plants, such a typical construction that causes the most problems when assessing the technical condition is coal or fine coal storage tank usually in the form of bunker batteries supplying power boilers. In practice, access to the interior of such bunkers is possible only when the power unit is put out of service (boiler extinguish) in order to repair, upgrade or expand it. In presented paper on the example of two coal bunkers (from a battery consisting of four such constructions) of one of the power plants located in southern Poland, the authors want to present and discuss some specific problems that occurred in the assessment and analysis of the technical condition of this type of specific industrial structure.
Highlights
The issues of technical condition assessment of various types of industrial structures are well known and recognized
There were joint ventures created by international teams, as SAFERELNET: Thematic Network on Safety and Reliability of Industrial Products, Systems and Structures [3], or a handbook created as a result of the Czech-Norwegian grant, Sýkora et al [4] and publication Brehm and Bolt [5]
A probabilistic approach is applied in the process of assessing the condition of existing structures, which was clearly accepted in the 2001 Joint Committee on Structural Safety [10] report
Summary
The issues of technical condition assessment of various types of industrial structures are well known and recognized. Access to the interior of such bunkers is possible only when the power unit is shut down from service (boiler extinguish) in order to repair, upgrade or expand it Is it possible to temporarily empty the bunker, and sometimes even several bunkers from the battery, and to allow the assessment of the actual technical condition of both the inner surface of its walls and those built inside other structural elements. On the example of two coal bunkers (from a battery consisting of four such constructions) of one of the heat and power plants located in southern Poland, the authors want to present and discuss some problems that occurred in the assessment and analysis of the technical condition of a specific industrial structure
