European Union has recently made a new directive to impose a classification system based on boilers efficiency. This new regulation generates the necessity of create new boilers more energy efficient like the one developed throughout this thesis. An innovative combined heat and power boiler (CHP boiler) called Boiler Booster is studied in this thesis. The main focus will therefore be to design the Boiler Booster taking the advantage of using the patented absorption technology developed by ClimateWell AS. Natural Gas is burned in the jacket boiler in order to use exhaust gases to heat up the water circuit from the heating system. The heat exchanger design integrates two identical tubes with eight small ClimateWell tubes in each, which transfer heat with exhaust gases. The purpose of the thesis is to design the Boiler Booster, an enhancement of current CHP boilers, which are able to deliver more power to the heating system. This is possible by extracting the maximum power from the exhaust gases and hence, lowering their final temperature as well as generating condensation of the water inside them. The optimal Boiler Booster size, the tubes shape and the use of fins along them to enhance the convective heat transfer are studied with the Engineering Equation Solver (EES) program. Finally, results of different designs are studied to end up with the best Boiler Booster design.
