With nonlinearity, large lag and time-varying model parameters of cement rotary kiln, this paper proposed a burning zone temperature control system of cement rotary kiln based on CMAC neural network. By Dynamic adjustment of PID controller parameters with CMAC neural network, combined with rotary kiln temperature control mechanism, the temperature controller based on CMAC-PID was designed. Then...

3333679 37 6 $ E The Effect of Kiln Temperature on DRE and Organics Concentrations in Incinerator Ash W. R. Schofield, PhD, PE; W. V. Walls, PE; and Thomas Jones Chemical Waste Management, Inc. (CWM) conducted RCRA and TSCA trial burns on the world-scale hazardous incinerator a t Port Arthur, Texas, in early 1990. Subsequent commercial operation revealed start-up problems which included (1) com...

background : necessity of evaluating heat stress in the workplace, require validation of indices and selection optimal index. the present study aimed to assess the precision and validity of some heat stress indices and select the optimum index for using in heavy work activities in hot and dry climates. methods: it carried out on 184 workers from 40 brick kilns workshops in the city of qom, cent...

A SUBSTANTIAL PERCENTAGE of 2 by 4 studs cut from southern pine veneer cores or small logs warp excessively when kiln-dried to 9 or 10 percent moisture content (MC). Warp can be significantly reduced by mechanical restraint during the drying process (Koch 1971). One practical way of applying restraint calls for a top load on each kiln stack to impress sharply toothed kiln sticks into each board...

Prevention and mitigation of acid rock drainage from mining are decisive for limiting environmental impact. Five by-products and industrial remnants (lime kiln dust, blast furnace slag, granulated blast furnace slag, cement kiln dust and fly ash) were investigated for their suitability to prevent acidity and metal(loid)s during leaching from highly sulfidic (50wt%, sulfide) waste rock in small ...

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 ...

Re-creation of the land use transformation at different periods in time is valuable for revealing how policy change influence ancient Fu Liang kiln. To date, there has been little focused on the model of historical Fu Liang kiln change. On the contrary, current research has emphasized that the transformation process of kiln has been described by literal presentation. However, Dynamical and visu...
