“…They concluded that, further improvements are needed for syngas use in gas turbine engines especially with respect to system performance and plant design. The results of the combustion of low calorific syngas fuels derived from gasification of waste biomass were presented by Kwiatkowski, et al [5]. Computational fluid dynamics of the combustion of two different gases derived from gasification of waste wood chips and turkeys feathers was presented in this paper.…”

Biogas fuel is a sustainable and renewable fuel produced from anaerobic digestion of organic matter. The biogas fuel is a flammable mixture of methane and carbon dioxide with low to medium calorific values. Biogas is an alternative to conventional fossil fuels and can be used for heating, transportation and power generation. CFD (computational fluid dynamic) analysis of the combustion performance and emissions of biogas fuel in gas turbine engines is presented in this study. The main objective of this study is to understand the impact of the variability in the biogas fuel compositions and lower heating values on the combustion process. Natural gas, biogas from anaerobic digester, landfill biogas, and natural gas/biogas mixture fuels combustion were investigated in this study. The CFD results show lower peak flame temperature and CO mole fractions inside the combustor and lower NO x emissions at the combustor exit for the biogas compared to natural gas fuel. The peak flame temperature decreases by 37% for the biogas landfill (CO 2 /CH 4 = 0.89) and by 22% for the biogas anaerobic digester (CO 2 /CH 4 = 0.54) compared to natural gas fuel combustion. The peak CO mole fraction inside the combustor decreases from 9.8 × 10 -2 for natural gas fuel to 2.22 × 10 -4 for biogas anaerobic digester and 1.32 × 10 -7 for biogas landfill. The average NO x mole fraction at the combustor exit decreases from 1.13 × 10 -5 for natural gas fuel to 0.40 × 10 -6 for biogas anaerobic digester and 1.06 × 10 -10 for biogas landfill. The presence of non-combustible constituents in the biogas reduces the temperature of the flame and consequently the NO x emissions.

“…Producer gas can be derived from any kind of biomass through a gasification process. It is a combustible gas mixture with hot, dirty (particulate and tar), and LHV properties . Ergo, an efficient combustion process is required in order to use PG for the heating process and power generation system.…”

Simulation of producer gas flameless combustion with fresh reactant diluted by hot flue gas

Summary Flameless combustion is considered as a flexible and efficient combustion process for low heating value gas fuel. This paper presents numerical simulations of premixed flameless combustion using producer gas as a fuel. Different initial conditions of the premixed fresh reactant (air/fuel mixture) and dilution levels are taken into account for the investigation. The numerical simulations were investigated using a network of chemical reactor models with the detailed reaction mechanism of GRI‐Mech 3.0. A threshold dilution level for flameless combustion fuelled by producer gas was determined. The numerical results show that dilution of the fresh reactant with hot combustion products and initial fresh reactant temperature play important roles in flameless combustion formation and its auto‐ignition behaviour, rather than equivalence ratio of the fresh reactant. In the flameless combustion regime, temperature and chemical concentrations were reduced while chemical kinetics process was decelerated, resulting in delay of the auto‐ignition process.

Summary The following paper presents in detail the results of two separate test runs of the leather waste gasification process. The first one was conducted in a laboratory and the second in an industrial installation with 2.5 MW of thermal power. The aforementioned gasification plant transforms 1000 kg/h of various leather waste with ER = 0.38‐0.4 producing hot producer gas with a calorific value of 4.1‐6.5 MJ/m3 used for steam production. This local energy center uses waste from a leather processing factory to secure the energy needs of the host plant and produces ashes with up to 55% of Cr2O3 suitable for Cr recovery and reuse in the tanning process. The gasification of refuse‐derived fuel derived from the used leather goods illustrating the effectiveness of separate collection and thermal transformation of Cr containing waste was tested as a path to closing the chrome economy cycle in the leather industry. Moreover, the effectiveness of Ca(OH)2 for the purification of flue gas resulting from syngas burning and removal of SO2 and HCl was taken into account. Ashes analysis from gasification and flue gas cleaning showed very low Cr(VI) content. The study, according to the laboratory and industrial‐scale tests, proves that gasification leads to effective energy conversion of leather waste and can be advantageous in comparison to incineration, mainly due to producing safer ashes that are easier for handling and processing, with the simultaneous production of valuable syngas.
