DEVELOP A DYNAMIC MODEL OF GAS AND OIL BURNED BOILERS FOR OPTIMISATION OF BOILER CONTROL IN CENTRAL HEATING SYSTEMS

Zaiyi Liao, Foroutan Parand

Abstract: An innovative boiler controller was developed using the simulator described in this paper. A dynamic model of commercial hot water boilers has been developed and integrated with other heating system component models to create a simulator of central heating systems. Detailed experimental data was obtained to validate the boiler model. The validation results indicate that the model can accurately simulate both transient and steady state performance of such boilers as installed in central heating systems. The model development was carried out under a European Commission project with the aim to improve the overall efficiency of water heating systems. The simulator was subsequently used to develop an innovative boiler controller that has been tested in simulation, emulation, a test building and field trials in real buildings with successful results. Applying the controller to most boilers will result in significant energy savings. This paper presents the mathematical boiler model and its validation. The new boiler controller is also discussed.
