    Technology:

    Symbiosis combining large scale solar heating, gas fuelled CHP and absorption heat pump.

    Silkeborg municipal-owned district heating company in Denmark, supplies most of the city Silkeborg with heat. The 400 GWh annual heat production has for 20 years been provided with a gas fuelled CC plant and gas boilers. Due to lower electricity prices, this production has been less cost effective recent years.

    Technology:

    A success criteria for good water treatment in district heating systems is optimum technical and economical operation both in the short and in the long run. Likewise, low chemical consumption is a success criteria, since the environment will be the least stressed by leakage of district heating water and at the same time, the risk of corrosion will be reduced.  

    This means:
    - Minimization of corrosion and formation of deposits.
    - Optimum plant and operating economy.
    - Minimum maintenance costs.
    - Minimum internal and external environmental impact.
