ABSTRAKT

Conventional central power generation shows a high electrical efficiency, hut the transmission of the energy to the consumer is hindered by distribution losses. Decentralized combined heat and power (CHP) generation in proximity to the customer is an alternative to reduce transmission losses. Based on a natural gas-fired micro-CHP system, a liquid fuel burner system is developed. The modification of the natural gas system for operation with light fuel oil (no. 2) is the focus of this project. An innovative vaporization technique, i.e., cool flame vaporization, is used to create a homogenous fuel-air mixture. The combustion of the fuel-air mixture is surface stabilized, using the surface burner of the natural gas system. Different atomization techniques and nitrogen oxide reduction concepts, such as air staging and exhaust gas recirculation, were evaluated. By fulfilling stringent emission targets and safe operation in the complete power range, the concept of micro-CHP aims to achieve an efficient use of limited resources.
