Relationship between Transport Power and Reliability of District Heating System

Abstract:

Circulating pump is used to transport hot water from source to user in heating network. It has been always neglected that transport power affects reliability of district heating system directly. In this paper, the ratio of the speed of circulating pump under design condition to the rated speed was structured to describe the allowance of circulating pump, as well as its transport power. Taking example for a single-source district heating system, the effect from transport power to reliability was analyzed by calculating the comprehensive reliability. Thus, the quantitative relationship between transport power and reliability of the district heating system was discovered, showing the maximum reliability with the related transport power of circulating pump. In addition, the analysis shows that circulating pump with steep-type performance curve can improve reliability to some extent.
