The Influence of Oversized Boilers on Power Efficiency, Energy Consumption and Cost in Energy Flexible Heat Stations. Part 1

Abstract:

Oversized boilers in in-house heat stations are relatively common. This study demonstrates the effect of installed overcapacity in heat stations with regard to the buildings heat load. Potential energy savings are calculated on basis of a heat station containing both fuel oil boiler and electric boiler. Correct installed capacity is defined as the capacity of a boiler designed to meet the design outdoor temperature, DOT. The baseline for normal consumption has been defined by utilization of correct designed boilers operated under various climatic conditions for a normal year. This baseline has then been compared to consumption calculation done with oversized boiler capacity. The energy consumption calculation is done on an hourly basis for one year. The results show a clear connection between the boiler size, boiler efficiency and potential savings in energy and cost.
