The theme of this article is to establish a basis for a physical model of optimization the kinetics of the process caustification (firing). In developing the mathematical model were used available data on the subject. The experimental part was carried out in order to find the optimal state of firing caustic magnesite at a given temperature and its reactivity to fast speed rotary kiln (FSRK) and...

A flame shape descriptor based on coordinates of edge of a flame is proposed. Artificial Neural Network is used to predict flame image edges .A flame with constant x-coordinate is used in the present study. Y-coordinates of flame edge are predicted using neural network. Recognition experiments were carried out using flame image sampled from a burning candle. The results show a good recognition ...

The cement industry is the second largest source of global man-made CO2emissions after power industry, and adoption O2/CO2combustion technology for kilns great significance in reducing CO2emissions. In this paper, effects pulverized coal mixed air combustion on velocity field, temperature CO2and NOx concentration distribution rotary kiln were investigated by CFD technique. results showed that t...

Rotary kilns are used in many industries to process bulk raw materials. In the building materials industry, rotary widely for heat treatment. However, fuel utilization factor is extremely low. Thus, of cement clinker fired furnaces, thermal efficiency which does not exceed 55-60%. Therefore, task increasing such units relevant. operating losses environment only through furnace body reach 20-25%...

in this research, energetic andexergetic analysis of calcium oxide formation, co2 emissions, andenvironmental effects during the clinker production process in rotary kilnare investigated. first the energy and exergy analysis of rotary kiln were carried out according to the first and second law of thermodynamics based on dead state, respectively. consequently, the amount of co2 emissions associa...
