“…The waste of this kind is often very homogeneous, so that the technology of thermal processing can be developed. The quantity is relatively small and, in order to maximise profits avoiding costly transportation to the distant processing plants, it is advantageous to use small units employing reliable technology of up-draft gasifiers to produce energy for local consumption [1][2][3][4]. Examples of such solutions are installations gasifying feathers from poultry slaughterhouse [4], waste leather from tannery [5], low-quality fresh wood waste [5], spent mushroom substrate [6], RDF or municipal waste in small communities [5,7].…”

The industrial combustion chamber designed for burning low-calorific syngas from gasification of waste biomass is presented. For two different gases derived from gasification of waste wood chips and turkey feathers the non-premixed turbulent combustion in the chamber is simulated. It follows from our computations that for stable process the initial temperature of these fuels must be at least 800 K, with comparable influx of air and fuel. The numerical simulations reveal existence of the characteristic frequency of the process which is later observed in high-speed camera recordings from the industrial gasification plant where the combustion chamber operates. The analysis of NO formation and emission shows a difference between wood-derived syngas combustion, where thermal path is prominent, and feathersderived fuel. In the latter case thermal, prompt and N 2 O paths of nitric oxides formation are marginal and the dominant source of NO is fuel-bound nitrogen.

“…Meanwhile, cold gas efficiency (CGE) is defined as the fraction of the chemicallybound energy in the biomass that is converted into chemically-bound energy in the product gas from the gasification process where ṁ PG and ṁ Bio are the mass flow of product gas and biomass in kg/h, respectively, and LHV PG and LHV Bio are the lower heating value of the product gas and the biomass in MJ/kg, respectively [6].…”

Torrefied Biomass Gasification: A Simulation Study by Using Empty Fruit Bunch

Abstract.A fixed bed gasification model has been developed by using Aspen Plus as the simulation and modelling tool. The feedstock chosen consisted of raw empty fruit bunch (EFB) and torrefied EFB at 300°C. The hydrogen gas composition obtained using fixed bed gasification model from all feedstock were then analysed together with lower heating value (LHV) and cold gas efficiency (CGE). The simulation results show that as the gasifier temperature is increased, the amount of hydrogen produced is also increased and an increment of air-to-biomass ratio (ABR) reduces the amount of hydrogen produced. Besides, the torrefied EFB produced a higher amount of hydrogen gas (6.52%) at gasifier temperature of 800°C and air-to-biomass ratio (ABR) of 0.2 compared to raw EFB (5.09%). This indicates that torrefied biomass at higher temperature improves hydrogen production. In addition, the use of torrefied biomass also contributes to higher LHV and increases the efficiency of the gasification process.

“…At around 18-22%, overall waste to electricity conversion efficiencies for gasification used with a conventional steam cycle are comparable to incineration. Nevertheless, conversion efficiencies can be increased to around 26-28% through the use of a gas engine or up to 30% with a gas turbine (Greater London Authority, 2008 andArena, 2012). As gasification plants are generally more complex than incinerators, they do tend to be more costly.…”

A multi-criteria analysis of options for energy recovery from municipal solid waste in India and the UK

Energy recovery from municipal solid waste plays a key role in sustainable waste management and energy security. However, there are numerous technologies that vary in suitability for different economic and social climates. This study sets out to develop and apply a multi-criteria decision making methodology that can be used to evaluate the trade-offs between the benefits, opportunities, costs and risks of alternative energy from waste technologies in both developed and developing countries. The technologies considered are mass burn incineration, refuse derived fuel incineration, gasification, anaerobic digestion and landfill gas recovery. By incorporating qualitative and quantitative assessments, a preference ranking of the alternative technologies is produced. The effect of variations in decision criteria weightings are analysed in a sensitivity analysis. The methodology is applied principally to compare and assess energy recovery from waste options in the UK and India. These two countries have been selected as they could both benefit from further development of their waste-to-energy strategies, but have different technical and socio-economic challenges to consider. It is concluded that gasification is the preferred technology for the UK, whereas anaerobic digestion is the preferred technology for India. We believe that the presented methodology will be of particular value for waste-to-energy decision-makers in both developed and developing countries.
