Diagnostic Protocol for Thermal Performance of District Heating Pipes in Operation. Part 1: Estimation of Supply Pipe Temperature by Measuring Temperature at Valves after Shutdown

نویسندگان

چکیده

This study evaluates temperatures measured at district heating (DH) valves in manholes and their usability for non-destructively assessing the thermal performance of buried DH pipes. The was conducted as a field test which part network shut down temperature decline analysed terms absolute response time from pipe to top valve. calculated supply by drainage were good agreement, with 1% deviation. valve measurement analysis this shows that has potential serve point status network. However, shutdown measurements greatly affected manhole environment.

Preparation and evaluation of geopolymer composites containing alumina particles at ambient temperature and after heating

In this research, geopolymer composites were prepared using metakaolin along with silica fume and potassium hydroxide as alkaline activators and alumina particles. The effect of alumina particle size to achieve castable microstructure and their mechanical properties were investigated. Different Si:Al mole ratio (1.5, 2, 2.5 and 3) and K:Si mole ratio (0.20, 0.25, 0.33) were formulated and the s...

Temperature prediction at critical points in district heating systems

Current methodologies for the optimal operation of district heating systems use model predictive control. Accurate forecasting of the water temperature at critical points is crucial for meeting constraints related to consumers while minimizing the production costs for the heat supplier. A new forecasting methodology based on conditional Finite Impulse Response (cFIR) models is introduced, for w...
