  7. Abstract:
  8. Hydrazine is considered as one of the most dangerouswaste materials from the environmental point of view. It can lead to both air and soil pollutions. Unfortunately,Hydrazine fuel is largly used in aerospace industry. Therefor, the aerospace industries are indirectly engaged with such pollutions.As a remedy incineration can be considered a very effective solution to destroy hydrazine fuel. In this thesis, we are faced with the conceptual design of an incinerator, which is going to be used for hydrazine incinerations.In this regard we are expected to consider all restrictions,which are required to be considered in a reed incinerator design and application. Therefore, we need to determine these restrictionsin advance. In addition,we consider all the criteria required to be regarded in our conceptual design.A few of these criteria include the incinerator temperature, the waste residence time, turbulence and mixing of flow in the combustion zone, the waste flow rate and so on. During the conceptual design, we determine aumber of important characteristics for the incinerator,including the type of burner, the number of burners,the fuel type. We also determine different incinerator sizes in our design including its diameter,length, and shape, and the inlet sizes for the hydrazine,air and fuel flows. We respect the primary incinerator standards in our conceptual design as well. To validate our designed incinerator,we simulate its working conditions using the CFD. We eventually find that a cylindrical incinerator with a length of three meters and a diameter of one meter would be suitable to incinerate the hydrazine waste with a flow rate of 500 Kg/h
