SO2 Release as a Consequence of Alternative Fuel Combustion in Cement Rotary Kiln Inlets

Linear Identification of Rotary White Cement Kiln

Rotary cement kiln is the main part of a cement plant that clinker is produced in it. Continual and prolonged operation of rotary cement kiln is vital in cement factories. However, continual operation of the kiln is not possible and periodic repairs of the refractory lining would become necessary, due to non-linear phenomena existing in the kiln, such as sudden falls of coatings in the burning ...

Modelling of the Fuel Stream and Combustion in a Rotary-kiln Hazardous Waste Incinerator

Hazardous wastes from various industrial processes are normally incinerated with rotary kilns in order to comply with current environmental regulations. They have often very complicated chemical compositions in a variety of physical forms and difficult to characterise. The complex transport phenomena within the incinerator are not well understood, and the incineration process expects large unce...

Sulfur Release from Cement Raw Materials during Solid Fuel Combustion

During combustion of solid fuels in the material inlet end of cement rotary kilns, local reducing conditions can occur and cause decomposition of sulfates from cement raw materials. Decomposition of sulfates is problematic because it increases the gas-phase SO2 concentration, which may cause deposit formation in the kiln system. SO2 release from cement raw materials during combustion of solid f...

Identification of Cement Rotary Kiln in Noisy Condition using Takagi-Sugeno Neuro-fuzzy System

Cement rotary kiln is the main part of cement production process that have always attracted many researchers’ attention. But this complex nonlinear system has not been modeled efficiently which can make an appropriate performance specially in noisy condition. In this paper Takagi-Sugeno neuro-fuzzy system (TSNFS) is used for identification of cement rotary kiln, and gradient descent (GD) algori...
