  • 4-E analysis of heavy oil-based IGCC
    Rasoul Shahsavan Markadeh, Arash Arabkhalaj, Hojat Ghassemi, Pouria Ahmadi
    Energy Sources Part A Recovery Utilization and Environmental Effects, 2020
    This article aims to evaluate different heavy oil derivatives as feedstock for integrated gasification combined cycle (IGCC) through energy, exergy, economic, and environmental analysis. For this purpose, the simulation of a 450 MW IGCC in Aspen Plus is performed, and optimum values of operational parameters are obtained to maximize electrical efficiency. A heavy fuel oil (Mazut), Vacuum residue (VR), and vacuum residue water slurry (VR+W) are considered as input feedstock. The thermodynamics results show that VR case with first and second law electrical efficiencies of 34.6 and 34.4% has the best electrical performance. However, by considering recoverable heat, the total efficiencies of VR+W is the maximum with 45.7 and 45.5% for energy and exergy, respectively. The economic analysis demonstrates that the total capital costs are in the same order, but because of differences in annual fuel cost for a payback period of 5 years, the electricity price should be 0.143, 0.127, and 0.125 ($/kWh) for Mazut, VR+W, and VR cases, respectively. Finally, concerning performance, economic, and environmental aspects, it seems the proposed IGCC plant with heavy oil feedstock has the ability to compete in the power generation market.
  • Droplet evaporation under spray-like conditions
    Rasoul Shahsavan Markadeh, Arash Arabkhalaj, Hojat Ghassemi, Asghar Azimi
    International Journal of Heat and Mass Transfer, 2020
    Evaporation of a droplet in a spray is affected by the neighboring droplets via their heat and mass diffusion. Aiming to investigate this effect, in this paper, the evaporation of a droplet is considered while it is assumed to be surrounded by the same evaporating droplets. A fully transient approach is applied to simulate the evaporation of a multicomponent droplet in a hypothetical spherical bubble. Three different fuels are employed; heptane, hexadecane, and a 50%-50% of their blend. The heat and mass influence extents of a droplet are introduced and their variations are investigated during the evaporation. To show the effects of neighbor droplets, the temperature and species concentration in both liquid and gas phases are compared to those of an isolated droplet. The effects of the droplet spacing, fuel types, and ambient temperature are studied. The result unveils that the effects of neighbor droplets become significant for spacing parameters less than 55 correspondings to the equivalence ratio around 10. Also, this effect becomes attenuate at higher ambient temperatures and lighter fuels.
  • Fully transient modeling of the heavy fuel oil droplets evaporation
    Asghar Azimi, Arash Arabkhalaj, Rasoul Shahsavan Markadeh, Hojat Ghassemi
    Fuel, 2018
    In this paper, evaporation of heavy fuel oil (HFO) droplet under atmospheric pressure is studied through a fully transient approach. The HFO is considered as a multi-component liquid with temperature-dependent properties. The performance of this fully transient approach is evaluated for different fuels and results are compared with available experimental data for gasoline and diesel fuel. The comparison shows excellent agreements, and also reveals the flexibility of this approach for interpretation and justification of the evaporation process details by using of internal distribution of temperature and composition. Based on distillation curve, several multi-component compositions are presented for the HFO. The composition is broken down into several pseudo-components and the effects of number of components and their method of selecting are studied comparatively. It shows that despite the wide range of compositions of heavy fuels, a compound consists of a few numbers of pseudo-components can be a suitable representative for them. Also pseudo-components should be chosen with equal interval temperature and narrow boiling temperature range. The effects of environment temperature on the evaporation of droplets are investigated in a parametric study. The results show that internal temperature distribution is not very sensitive to the ambient temperature due to the high boiling temperature of heavy components of the fuel. Also wide span of temperature in the heavy fuel droplet makes it possible to predict the initial condition of pyrolysis and thermal cracking of heavier components.
  • A discrete multicomponent droplet evaporation model; effects of O2-enrichment, steam injection, and EGR on evaporation of diesel droplet
    Rasoul Shahsavan Markadeh, Hojat Ghassemi
    Numerical Heat Transfer Part A Applications, 2018
    A discrete multicomponent (DMC) model for droplet evaporation in convective ambient is developed. Three different sets of correlations for Nusselt and Sherwood number are examined. The model is compared with experimental data for single and multicomponent droplet evaporation at different conditions and the most suitable set of correlations is selected. Having validated model, the diesel droplet evaporation under different ambient conditions and compositions is investigated. Increasing of oxygen mass fraction in N2–O2 mixture ambient from 0 to 1 first decreases and then increases the lifetime. Steam addition enhances the evaporation rate and it affects evaporation more significantly at higher temperatures. Exhaust gas recirculation (EGR) results in slight variations in droplet lifetime and its heating period.
  • Effect of unsteadiness on droplet evaporation
    Asghar Azimi, Arash Arabkhalaj, Hojat Ghassemi, Rasoul Shahsavan Markadeh
    International Journal of Thermal Sciences, 2017
    The aim of the present study is an investigation of the impact of gas phase unsteadiness in the evaporation of single component fuel droplets. For this purpose, the results of quasi-steady (QS) approach and Abramzon-Sirignano model (AS) are compared with the fully transient (FT) approach. In the FT and QS approaches, species, momentum and energy conservation equations in gas phase and energy equation in liquid phase have been solved in consideration of totally variable properties. The results of the FT approach at atmospheric pressure for fuels with different volatilities, show a very good agreement with experimental data which are available in the literature. The results of different approaches are obtained for three different fuels, heptane, decane, and hexadecane at temperatures of 500 K and 800 K. By using two measures of unsteadiness related to the mass fraction of fuel vapor and surface temperature, the amount of the steadiness of processes in the gas phase has been checked and deviation of the QS approach and AS model from FT approach has been justified. The results indicate that the temperature and type of fuel have significant effects on unsteadiness. Increasing temperature and decreasing the fuel volatility, increase the deviation of the two approaches from FT approach. Also it is found that the QS approach gives better results for small diameters while the AS model shows better lifetime estimation for large diameters.
  • A fully transient approach on evaporation of multi-component droplets
    Arash Arabkhalaj, Asghar Azimi, Hojat Ghassemi, Rasoul Shahsavan Markadeh
    Applied Thermal Engineering, 2017
    This paper deals with multi-component droplet evaporation. For this purpose, species, momentum, and energy equations for the gas phase are solved numerically together with species and energy equations of the liquid phase. A fully transient (FT) approach with variable properties in terms of time and space is employed. The results are compared with available experimental data in the literature for binary- and multi-component droplets at various temperatures and satisfactory agreements are seen. In order to study the effect of volatility on the droplet evaporation, heptane, decane, and hexadecane are examined and multi-staged feature of evaporation is captured. Also, the range of droplet internal bubbling is estimated by investigating internal temperature and mass fraction variations. The results indicate that diffusion enthalpy term in the liquid phase plays a significant role in the deviation of multi-component droplet evaporation trend from the single component. Furthermore, the quasi-steady (QS) assumption in the gas phase of droplet evaporation is evaluated. The comparison between FT and QS approaches shows that the amount of heavier component in the droplet composition and increasing volatility difference of components increase the deviation of two approaches.
  • Modeling of high-ash coal gasification in an entrained-flow gasifier and an IGCC plant
    Hojat Ghassemi, Seyed Milad Mostafavi, Rasoul Shahsavan-Markadeh
    Journal of Energy Engineering, 2016
    Gasification of high-ash coal in dry and slurry entrained flow gasifiers is investigated through equilibrium modeling. Effects of oxygen- and steam-to-coal mass flow rate ratios in a dry-fed gasifier and also the effect of water concentration in slurry on composition, temperature, heating value, and cold gas efficiency are studied. It is observed that adding steam to the gasifier reduces oxygen consumption, and the optimum ratio of oxygen-to-coal mass flow (O/F) decreases. At high enough O/F ratios, the steam-to-coal mass flow (S/F) and water-to-coal mass flow (W/F) ratios have no significant influences on gasifier efficiency. It is also observed that for coal, which has a high ash content, dry-fed gasification is preferable. In this type of gasifier, optimum O/F and S/F ratios with respect to cold gas efficiency are determined to be 0.5 and 0.8, respectively. Simulation of the integrated gasification combined cycle (IGCC) in Thermoflow indicates that, for a typical 450-MW combined cycle, 56.6 kg...
  • Thermodynamic evaluation of integrated gasification combined cycle: Comparison between high-ash and low-ash coals
    Arash Arabkhalaj, Hojat Ghassemi, Rasoul Shahsavan Markadeh
    International Journal of Energy Research, 2016
    Summary In the present study, a coal-integrated gasification combined cycle power plant is simulated. A high-ash coal and low-ash coal are considered to compare the performance of the plant. The combined cycle is in typical commercial size with 450 MW capacity. The feeds are Tabas and Illinois #6 coals which approximately contain more than 30% and 10% ash and have higher heating values of 22.7 MJ/kg and 26.8 MJ/kg, respectively. Energy and exergy analyses are done by aspen plus® and ees, respectively. Energy analysis shows that the overall efficiencies of power plants using high-ash and low-ash coals are 33% and 28%, respectively. The result shows that in high-ash case, 52 kg/s coal, 10 kg/s water, and 1050 kg/s air and in low-ash case, 48 kg/s coal and 820 kg/s air are required for providing mentioned power, approximately. Exergy analysis shows that maximum exergy destruction is in heat recovery steam generator unit. Investigating the emissions shows that high percent of ash in the coal composition has slight effects on the IGCC pollution. Finally, from thermodynamic viewpoint, it is concluded that the high-ash coal, like the conventional one, can be used as thermally efficient and environmentally compatible feed of IGCCs.

  • On dynamic behavior of premixed counterflow flame propagation
    M.Motahari Nezhad, M. Beheshti, S. Shahraki, H. Ghassemi, R. Shahsavan-Markadeh
    Thermochimica Acta, 2016
    We have provided a detailed numerical model for simulating flame propagation in a premixed counterflow configuration. It is an unsteady state, one-dimensional model based on the heat and mass balance equations. Attention is focused on the impact of the non-dimensional numbers namely Lewis number, Damkohler number, and Zeldovich number on the flame temperature profile. Also, we have explored what happens when we continue the solutions for higher heat losses. It was found that with increasing the Lewis number the flame temperature decreases, while a further increase in Lewis number results in constant value of the flame temperature. Model predictions have been compared with available data from the literature, which have showed fully good agreement.
