“…Regarding dioxins, it is known that almost the entire amount fed along the waste is destroyed in the combustion process, being newly synthetized in the boiler (Vehlow 2013;Hunsinger et al 2002). Due to the complexity of the chemical synthesis of dioxins, most Aspen models developed for waste-to-energy simulation do not consider this process (Ding et al 2018;Jannelli and Minutillo 2007;Cimini et al 2005).…”

“…The decomposition processes of MSW in its main constituents (i.e., ultimate analysis) and the combustion process were simulated using RYield and RGibbs reactors, respectively. The main products considered in the combustion process were H 2 O, N 2 , NO, NO 2 , O 2 , H 2 , C (solid), CO, CO 2 , Cl 2 , HCl, S, SO 2 , and SO 3 (Ding et al 2018). In RGibbs reactor model, a minimum in the Gibbs free energy is considered once the equilibrium is established in the reacting system.…”

“…The heat recovery system for steam generation was simulated using two Heater modules, one of them as a heater (i.e., hot side in the boiler) and the other one as a cooler (i.e., cold site in the boiler). The steam parameters (i.e., 400 • C and 4 MPa) were adopted from typical values of WTE plants (Kalogirou 2017;Ding et al 2018;Athanasiou et al 2015). The temperature of exhausted gases was settled as 180 • C. The steam produced was fed to a single steam turbine module, with a discharge pressure of 8 kPa.…”

Havana has the highest population and consequently generation of municipal solid wastes (MSW) in Cuba. In Havana, the final deposition method for MSW is mainly landfills. However, in most cases, they exceed their lifetime of operation becoming in reality dumpsites without energy recovery from wastes. In this regard, waste-to-energy is a well-established technology for MSW treatment. The aim of this work was to carry out a techno-economic assessment for a proposed waste-to-energy plant in the city of Havana. A step-wise methodology based on two process analysis tools (i.e., Excel and Aspen Plus models) was used for the technical evaluation. Simulation results are in agreement with data from real plants, showing that it is possible to produce 227.1 GWh of electricity per year, representing 6% of the current demand in Havana. The economic analysis showed the feasibility of the project with a net present value of 35,483,853 USD. Results from the sensitivity analyses show the effect of the economy of scale when changes in low heating value were considered. Finally, a hypothetical best scenario was studied considering the net effect on the average Cuban salary.

“…At the same time, an increased concentration of greenhouse gases is formed in the volume of exhaust gases which creates favorable conditions for capture and storage CO 2 [16][17][18][19]. Therefore, in the research literature, this technology is typically characterized as a near-zero emission technology [20][21][22].…”

Power Market Formation for Clean Energy Production as the Prerequisite for the Country’s Energy Security

The paper analyzes the main issues of power market development for clean energy production within the broader framework of ensuring the country’s energy security. In addition, special attention is paid to the technologies aimed at reducing emissions of toxic substances and greenhouse gases by the fossil-fired power plants. Even though the future electricity markets would most likely depend on the high shares of renewable energy sources (RES) in the electricity system, energy efficiency such as the one based on the near-zero emission technologies might also play a crucial role in the transition to the carbon-free energy future. In particular, there are the oxy-fuel combustion technologies that might help to reduce the proportion of unburned fuel and increase the efficiency of the power plant while reducing the emissions of flue gases. Our paper focuses on the role and the place of the near-zero emission technologies in the production of clean energy. We applied economic and mathematical models for assessing the prospects for applying oxy-fuel combustion technology in thermal power plants, taking into account the system of emission quotas and changes in the fuel cost. Our results demonstrate that at the current fuel prices, it is advisable to use economical combined cycle gas turbines (CCGT). At the same time, when quotas for greenhouse gas emissions are introduced and fuel costs increase by 1.3 times, it becomes economically feasible to use the oxy-fuel combustion technology which possesses significant economic advantages over CCGT with respect to the capture and storage of greenhouse gases.

“…In order to increase the efficiency of a boiler through proper control of the combustion process, an optimization software was developed, integrated with the distributed control system and the temperature profile measurement system in the furnace [5]. Similarly, software has been developed for the calculation and optimization of diesel operating processes and fuel injection [6], which have been complemented by the development of multiple numerical models for the simulation of different hydrogen combustion applications, synthesis of sustainable processes, process of combustion of chemical loops in fluidized bed with iron-based oxygen carrier, process of combustion of a pellet fall boiler, pyridine combustion, among others [7,8], however, these software are focused on research and lack a pedagogical component. Therefore, the main contribution of this work is to present the software CombustionUA v1.0, as a user-friendly graphic interface focused on the learning of combustion processes for undergraduate engineering students, allowing them to analyze important parameters such as dew point temperature, air fuel ratio [9,10], adiabatic flame temperature, heat transfer, and excess air.…”

This article presents the use of a graphical user interface in MATLAB® language called CombustionUA v1.0, for the thermodynamic study of the behavior of excess air, relative humidity, and air temperature in complete and incomplete combustion processes. The tool developed allows comparing the performance of different fuels under different operating conditions, since stoichiometry of different combustion reactions, calculation of thermochemical properties of fuels and energy balances have been programmed, so that the user can develop parametric case studies. The work shows the methodology and results of the application of three case studies, which were analyzed using the new educational software. In addition, the fundamental equations used in the development of the software algorithm are presented, as well as the maximum error rates obtained when validating the software in a group of mechanical engineering students at the Universidad del Atlántico. With the help of the software, it was concluded that the fuels with the best air fuel ratio and the highest heat transfer were determined, as well as the differences between the dew point temperatures of a complete combustion and an incomplete combustion.
