Temperature Control for Continuous Kilns

Formation, release and control of dioxins in cement kilns.

Co-processing of hazardous wastes in cement kilns have for decades been thought to cause increased emissions of PCDD/PCDFs--a perception that has been evaluated in this study. Hundreds of PCDD/PCDF measurements conducted by the cement industry and others in the last few years, on emissions and solid materials, as well as recent test burns with hazardous wastes in developing countries do not sup...

Residue-Derived Solid Recovered Fuel for Use in Cement Kilns

A Neuro-Fuzzy Controller for Rotary Cement Kilns

In this paper, we design a neurofuzzy controller to control several variables of a rotary cement kilns. The variables are back-end temperature, pre-heater temperature, oxygen content and CO2 gas content of the kiln. The fuzzy control system, as an advanced control option for the kilns, is intended to minimize the operator interaction in the control process. The proposed fuzzy controller uses a ...

Peykan check, a simple continuous quality control method for hematology analyzers

A simple inexpensive con!nuous quality control method, by means of eight basic blood coun!ng parameters, obtained from automated hematology analyzers, using pa!ent samples, is described. A few samples with low, normal and high values were selected and introduced to the instrument early in the morning as the first count, the results of which are plo#ed on the appropriate chart as dots. The sa...

Microfluidic chemostat and turbidostat with flow rate, oxygen, and temperature control for dynamic continuous culture.

This work reports on an instrument capable of supporting automated microscale continuous culture experiments. The instrument consists of a plastic-PDMS device capable of continuous flow without volume drift or evaporation. We apply direct computer controlled machining and chemical bonding fabrication for production of fluidic devices with a 1 mL working volume, high oxygen transfer rate (k(L)a≈...
