Generic lime kiln model.the generic lime kiln model is simplified from a more extensive model of an operational lime plant of nordkalk oy.the full plant model has been validated against the operational data.the validated full plant model was reduced to a more generic rotary kiln lime process setup and equipped with a flue gas circulation option.
Model from both thermal and chemical aspects of the waste combustion process are emphasized.the rotary kiln waste incinerator the incineration system is a standard type of industrial scale rotary kiln waste-incinerator operated at avr-chemie.it consists of a rotary kiln and a secondary combustion chamber scc.the rotary kiln is 4.2 m in.
The model is based on a global solution of three submodels for the hot flow, the bed and the rotating wallrefractories.information exchange between the models results in a fully coupled 3-d solution of a rotary lime kiln.the hot flow model uses block-structured body.
The heat required for the process is habitually supplied by the combustion of coal or, oil in the lime kiln.the combustion of these fuels produces additional co 2 emission which represents around 40 of the cement plant co 2 emissions.this emission can be reduced by switching to fuels, like natural gas, biomass or waste-derived fuels.
Model itself is in many ways the most important result of this thesis.the intent is that the reader will get a good picture of how the model works by reading this report.two different simulations were also conducted using the lime kiln model.the possible effects of using bio fuels in the lime kiln were studied in the first simulations.
