Waste Gas-to-Energy (WGtE) units allow the thermal processing of gaseous waste and its simultaneous energy recovery. However, the operation of WGtE units involves a large consumption of external fuel, and the flue gases produced require the application of flue gas cleaning technology. This thesis presents the results of a study focused on the topic of integrated WGtE unit design, which is an effective approach for achieving external fuel consumption savings while minimizing investment costs. Firstly, it presents the developed analytical method for the design of technological modifications of existing WGtE units treating waste gases in order to achieve their economical and more environmentally friendly operation. Attention is mainly paid to the description of the developed mathematical relations and graphical tools that can be used by the professional community, especially by the operators of WGtE units. To further reduce the negative environmental impact of these units, the second area addressed in the thesis is the development of flue gas cleaning equipment for the reduction of nitrogen oxides concentration. In addition to the technological concept and design of this device, the results of experimental work in laboratory and industrial environment are presented, where the great potential of using these devices in WGtE units as well as in a wide range of other industrial combustion plants was confirmed.
