Summary
The purpose of the project is to improve the efficiency of straw furnaces by cooling down the flue gas below dew point and thus making the upper calorific value of straw a realistic target for energy utilization. The heat exchanger to be used is a gas scrubber, which also is expected to reduce the emission considerably.
The paper present results from basic experiments with gas scrubbers used as heat exchangers. The aim of the work has been to investigate various packing elements and to determine constants being necessary for designing in actual cases.
The results of the experiments show that the gas scrubber is a very efficient heat exchanger. For example it has been calculated that an 18 kW heat loss through 300°C hot flue gas from a straw furnace can be recovered by a scrubber having a diameter of 230 mm and a height of 120 mm.
