Combined simulation of combustion and gas flow in a grate-type incinerator.
Computational fluid dynamic (CFD) analysis of the thermal flow in the combustion chamber of a solid waste incinerator provides crucial insight into the incinerator's performance. However, the interrelation of the gas flow with the burning waste has not been adequately treated in many CFD models. A strategy for a combined simulation of the waste combustion and the gas flow in the furnace is intr...
متن کاملThe cooling of atomic and molecular gas in DR 21
Aims. We present an overview of a high-mass star formation region through the major (sub-)mm, and far-infrared cooling lines to gain insight into the physical conditions and the energy budget of the molecular cloud. Methods. We used the KOSMA 3m telescope to map the core (10 ′ × 14 ′) of the Galactic star forming region DR 21/DR 21 (OH) in the Cygnus X region in the two fine structure lines of ...
متن کاملGrate Furnace Combustion: A Submodel for the Solid Fuel Layer
The reduction of NOx-formation in biomass fired grate furnaces requires the development of numerical models. To represent the variety in scales and physical processes playing a role in the conversion, newly developed submodels are required. Here, a submodel for the reverse combustion process in the solid fuel layer on the grate is described. The submodel is shown to give good predictions for th...
متن کاملNew Method for Controlling Combustion in a Grate Boiler
The control of disturbances due to fuel quality variation is important development area in the grate combustion technology. Main challenges in the control of the grate combustion are inhomogeneous fuel, variation in fuel moisture content, non-uniform distribution of fuel on the grate area and high percentage of combustibles in ash. Information on events which occur in the furnace plays an impor...
متن کاملNOx Emission Model for the Grate Firing of Biomass Fuel
Establishing an appropriate NOX production and decomposition model is of practical significance to the grate firing of biomass fuel. This study used the CHEMKIN software package to simulate the combustion process of biomass pyrolysis and char combustion. Through rate of production (ROP) analysis and simplification based on GRI-Mech3.0, the 15-step reaction mechanism of volatile-N converting int...
