Operational Reliability of the Rotary Cup Burner Type Saacke - SKV 60 of Marine Boiler

Abstract

One of the steps in predicting the reliability of a system includes determining the failure rate of the system’s components. The latter is obtained on the basis of the data available to the manufacturer, experience in using similar systems, using statistical methods and technical literature. In practice, the starting point in the process of foreseeing the reliability of any technical system is the assumption of constant failure rates. The system components’ failure rates which are determined in this way represent the so-called nominal values. This value is commonly modified by taking into account operation loads and environment conditions under which the observed system component is supposed to operate. In most cases the quantitative values of these two factors result from the engineering assessment that is based on the data available to the manufacturer or the user and takes into account the inevitable effect of a number of subjective factors. Predicting reliability is a process of determining numerical values which show the probability that machinery or engine will meet previously set requirements. The basic objective of reliability prediction is to ensure timely maintenance. This paper discusses predicting the operational reliability of the rotary cup burner type SAACKE - SKV 60 in the marine steam boiler TPK/VIC 8.5/7.
