An investigation of sorption fluids to recover latent and sensible heat from flue gas exhaust using the process of dehumidification has been carried out. Lithium bromide, potassium formate and lithium chloride were identified as suitable working fluids. The study also included the construction and testing of a small-scale experimental system. A detailed parametric model was developed, enabling different gaseous fuels to be investigated and the associated flue gas energy loss and potential heat recovery to be estimated. Results from the studies indicate a potential fuel saving of between 5 and 8% above that of a standard condensing boiler. An analysis of the likely environmental and economic impacts of systems based on sorption heat recovery was carried out.
