    Bio-char Refineries: An Accessible Approach For The Development Of Biomass-based Industry

    No full text
    Being a by-product of the well-established charcoal industry, slow pyrolysis bio-oil can be an excellent, cost-effective and renewable liquid fuel. However, even in Brazil, a country with a very clean energy profile and large-scale charcoal production, bio-oil is not properly utilised yet. A simple upgrade of traditional methods of charcoal production can significantly increase liquid fuel output. The concept of a bio-char-refinery, introduced in this paper, for production of charcoal, activated carbon, liquid fuel and variety of chemicals presents a possible approach for the development of biomass-based industry. Successful implementation of this concept could provide significant amounts of fuel and chemicals able to enhance economic development and reduce the consumption of petroleum derived products.

    Long-term impact of water desalination plants on the energy and carbon dioxide balance of Victoria, Australia : a case study from Wonthaggi

    No full text
    In 2007, the state government of Victoria, Australia, announced plans to build a large desalination plant with a capacity of 150 million m³ per year of desalinated water. Currently, the only feasible source for significant expansion of the greenhouse-gas neutral (GGN) energy generation in the state is wind power. A criterion for GGN of a desalination plant has been formulated. In a case of no greenhouse gas contribution from the desalination plant, the criterion is satisfied if the annual growth of the electrical energy generated by GGN sources is around 6–9% for the period 2010–2070. Higher annual growth of 18% for the period 2008–2015, 8% annually for the period 2015–2035 and 6% annual growth thereafter are required if the desalination plant is contributing to the greenhouse-gas balance of the state

    Explosions of methane/air mixtures induced by radiation-heated large inert particles

    No full text
    This work presents the results of an experimental and modelling investigation of the ignition of quiescent methane/air mixtures caused by radiation-heated large inert particles. The experimental data indicate that the explosion-delay time is inversely proportional to the radiative power flux. The delay time exhibits a minimum at a methane/air ratio near to stoichiometric. The mathematical model incorporates the basic principles of the thermal initiation mode of detonation phenomena. The experimental values of the explosion-delay time correlate with the predictions, hence lending weight to the proposed model.V.A. Stamatov, K.D. King and D.K. Zhan

    A Mie scattering investigation of the effect of strain rate on soot formation in precessing jet flames

    No full text
    This is an experimental study of soot formation in precessing jet flames. The Mie diagnostic technique was implemented to provide qualitative visualisation of the zones of soot formation. A range of conditionally sampled experiments was carried out. The characteristic Reynolds number based on the nozzle diameter, was varied from 4329 to 11223 and the Strouhal number based on the nozzle diameter, was varied from 0.0042 to 0.0245. The nozzle diameter was fixed at 5 mm and the jet exit angle at 45 deg. Experimental data were collected and used to show the tendencies in the formation of soot at different experimental conditions. It was found that the relative soot intensity increases with increase in both Re and St numbers.The instantaneous images reveal that soot is predominantly formed in sheets of varying thickness. Very little soot is observed in the near nozzle region, which is consistent with the idea that the formation of soot in appreciable quantities is kinetically limited. Readily observable are very broad regions of low signal spanning much of the flame. These broad regions are more prevalent in the high St number flames where strain rates are lower and residence times are longer. The experimental results support the hypothesis that low strain in a diffusion flame promotes soot formation and high emissivity (i.e., soot formation correlates inversely with flame strain)
