Energetic and exergetic analysis of alternative low-temperature based district heating substations arrangements

Energetic and Exergetic Analysis of Internal Combustion Engine Cogeneration System

In this article, the first and second law analysis of diesel engine based cogeneration system was performed. Fuel utilization efficiency, rate of power, and rate of process heat of the plant were determined and various efficiencies based on both energy and exergy methods and the performance assessment parameters are defined for both the system components and the entire cogeneration plant. The o...

Application of Service Oriented Architecture for Sensors and Actuators in District Heating Substations

Hardwired sensor installations using proprietary protocols found in today's district heating substations limit the potential usability of the sensors in and around the substations. If sensor resources can be shared and re-used in a variety of applications, the cost of sensors and installation can be reduced, and their functionality and operability can be increased. In this paper, we present a n...
