چکیده
The cement industry has become the second largest source of CO2 and NOx emissions after power industry, it is imperative to reduce emissions. O2/CO2 combustion technology can achieve enrichment reduction. As a result, its application possibilities are bright. In this article, TTF-type decomposition furnace serves as research object for CFD simulation. addition, effects pulverized coal combined O2/N2 mixed on velocity field, temperature material component, concentration distribution in investigated concerning changes kinetic parameters CaCO3 under different working conditions. Compared with atmosphere, high-temperature zone more uniform atmosphere. range reduced area extremely high temperatures. at exit by 37%. output be recycled reused greenhouse effect effectively. partial pressure increases 111 K, doubles O2 concentration, but decreases raw meal rate from 95.9% 82.2%. process must improved adapt technology.

Numerical Simulation of Combustion with Porous Medium in I.C. Engine
Porous media has interesting features in compared with free flame combustion due to the extended of the lean flammability limits and lower emissions. Advanced new generation of internal combustion (IC) engines are expected to have far better emissions levels both gaseous and particulate matter, at the same time having far lower fuel consumption on a wide range of operating condition. These c...

Combustion synthesis is a special thermophysico-chemical process applied for production of intermetallic compounds. In the present work, a reaction–diffusion numerical model was developed to analyze the combustion synthesis of aluminide intermetallics by self-propagating high-temperature synthesis process. In order to verify the reliability of the numerical model, an experimental setup was desi...

متن کاملNumerical Simulation of Premixed Turbulent Methane Combustion
In this paper we study turbulent premixed methane flames with swirl using three-dimensional numerical simulation. The simulations are performed using an adaptive time-dependent low Mach number combustion algorithm based on a second-order projection formulation that conserves both species mass and total enthalpy. The species and enthalpy equations are treated using an operator-split approach tha...
