Chapter
Flameless combustion, a process based on autoignition of convection transported kernels at the boundaries or even outside the lower explosive/flammability, is a promising candidate capable of simultaneously meeting emission reduction and efficiency improvement. Despite many similarities with more traditional combustion regimes, some key characteris...

Oxy-fuel combustion is a promising strategy to minimize the environmental impact of combustion-based energy conversion. Simple and flexible tools are required to facilitate the successful integration of such strategies at the industrial level. This study couples measured residence time distribution with chemical reactor network analysis in a close-...
Article
Full-text available
Carrier-phase direct numerical simulation of detailed NOx formation in pulverized coal flames (PCC) with fuel-bound nitrogen is conducted in a 3D temporally evolving mixing layer setup where Lagrangian particles (Colombian bituminous coal) in an air stream (upper half of the domain) mix with the products of lean volatile/air combustion in the lower...

Oxy-fuel combustion minimizes the environmental impact of combustion-based energy conversion. Simple and flexible tools are required to facilitate the successful integration of such strategies at the industrial level. Chemical Reactor Network (CRN) modelling guided by Residence Time Distribution (RTD) measurements enables the understanding of the d...
Article
Full-text available
The development of processes with near-zero emissions such as MILD, flameless, and OXY-fuel combustion are of great interest in various energy scenarios. The assessment and design of new burners to meet energy demands and pollution reduction strongly depends on an accurate description of the chemistry involved in the combustion process. The main ou...
Article
Full-text available
Strict environmental rules endorse moderate or intense low oxygen dilution (MILD) combustion as a promising technology to increase efficiency while reducing pollutants emission. The experimental and theoretical investigation of oscillatory behaviours in methane MILD combustion is of interest to prevent undesired unstable combustion regimes. In this...
Conference Paper
Full-text available
Residence time distribution measurements in a close to reality configuration devoted to both air and oxyfuel combustion are the starting point to develop a Chemical Reactors Network model. These models support the understanding of the mixing phenomena inside the combustor, and are well suited for performing parametric studies. Differences between t...
Conference Paper
Full-text available
A Computational Fluid Dynamic (CFD) study on hydrogen-air premixed combustion in a micro-combustor is investigated by solving three-dimensional (3D) governing equations. The effects of inlet geometry on the flame temperature, flame stability and micro combustor efficiency under different inlet flow rates and various equivalence ratios were studied...
Article
Full-text available
The combustion of effluent biogas from a palm oil mill is not feasible on a large scale because of its low calorific value (LCV). Therefore, the captured biogas is usually flared because of a lack of appropriate combustion technology. However, such biogas could be an excellent source of energy for combined heat and power (CHP) generation in palm oi...
Conference Paper
Full-text available
In this paper, the effects of biogas hydrogen enrichment on the characteristics of co-flow non-premixed flameless combustion and pollutant formation are developed experimentally and numerically. Biogas (40% CO2 and 60% CH4) is applied in the flameless furnace as a fuel and the combustion stability, temperature uniformity inside the chamber and NOx...
Article
Full-text available
Biogas released from palm oil mill effluent (POME) could be a source of air pollution, which has illustrated negative effects on the global warming. To protect the environment from toxic emissions and use the energy of POME biogas, POME is conducted to the closed digestion systems and released biogas is captured. Since POME biogas upgrading is a co...
Article
The purpose of this investigation is to analyze combustion characteristics of biogas flameless mode based on clean technology development strategies. A three dimensional (3D) computational fluid dynamic (CFD) study has been performed to illustrate various priorities of biogas flameless combustion compared to the conventional mode. The effects of pr...
Article
Full-text available
Biogas has a great potential to be applied for heat and power generation throughout the world due to its availability from various resources. However, one of the most important barriers of biogas utilization development is its low calorific value. In order to increase the performance of biogas in industrial application, hydrogen enriched biogas cou...
Conference Paper
Biogas, generated from breakdown of organic material, can derived from two main sources; municipal waste and agricultural residue. The municipal waste divided to two subgroup, solid waste and water waste, and agricultural waste and manure are the main subgroups of agricultural residue. Each of these sources can release biogas with different composi...
Conference Paper
The policies of greenhouse gas (GHG) reduction have been formed in most developed countries. Using the alternative energies such as renewable energies seems to be a way to decrease GHG, but a complete replacement of oil and coal with other energy resources is not feasible due to the numerous demands. Since fossil fuel will remain as the important s...
Conference Paper
Today, the demands for electricity have been increased drastically due to rapid industrialization and electricity has become the most usable kind of energy which is attached to the human life strongly. However, environmental issues emerged from energy generation should not be neglected. A big portion of the fossil fuel consumption is dedicated to p...

Full-text available
A numerical study on premixed combustion of CH 4 + CO 2 + air in premixed micro combustor is performed. In this study the inlet velocity and temperature of fuel and combustor geometry and size are kept to be the same but the effect on the variation of CO 2 dilution is observed. Results of this simulation show that as the CO 2 dilution rate increase...
