Purpose: Improved efficiency of wood chip boiler for district heating water

SEG A/S has delivered, installed and commissioned a new LT16C absorption chiller with a cooling capacity of 430 kW. The wood chip boiler supplies driving heat to the chiller's generator at a temperature of around 100°C. The scrubber circuit from smoke scrubber 2 is routed directly through the chiller evaporator circuit, where the scrubber water is cooled down to around 26°C. The cooling machine's evaporator tubes, end plates and reversing chambers are made of stainless steel to withstand the effects of the scrubber water. The chimney temperature is lowered close to 26°C, utilizing the heat of condensation from the flue gas to increase the overall efficiency of the plant. The chiller has been in operation since December 2014, with the project being completed in early 2015.
