摘要:

In recent years, there have been considerable developments in combustion models for fossil fuels that are used for design purposes by means of CFD modelling of combustors in power stations. As a result it is now possible to predict combustion behaviour in complex power station furnances fuelled by coal. Biomass is finding increasing use as a fuel in similar circumstances and at present there are no accurate models available. The object of this paper is to examine the applicability of the present models to wood (pine) and straw and to provide ways to improve their accuracy.

摘要:

India is the seventh largest energy consumer in the world. As the major contribution towards meeting the energy requirement is from fossil fuels, the emission from these fuels is enormous. A study is made on the available potential of energy both commercial and renewables in India. The utilisation pattern of commercial energy with regard to renewables is analysed. Renewable energy substitution in the total energy scenario is determined using an Optimisation Model. The model minimises cost-efficiency ratio. The parameters considered are social acceptance, demand, potential, reliability, emission and employment. The model determines that in 2020–21, biomass direct combustion will be utilised to an extent of 2.92 × 1015kJ and solar PV would be utilised to an extent of 2.32 × 1015kJ. The model is also run for 2000–01, 2005–06, 2010–11 and 2015–16. The results are presented. It is found that biomass direct combustion and solar is expected to have an exponential increase in India over the years.

摘要:

In the UK, about 30 million tonnes of Municipal Solid Waste (MSW) is generated each year and the disposal of this waste has become a national problem. The growing scarcity of landfill sites for municipal solid waste disposal and the increasing environmental problems with landfill waste has led to more stringent regulations and high cost of waste disposal. The landfill tax in the UK is designed to encourage energy efficient waste management strategies aimed at reducing the amount of waste to be landfilled through incineration while maximising the recovery of the waste energy. Efficient recovery of energy from waste is therefore an important aim for modern incinerator design. The incineration of MSW is known to be a very complex process since the waste is poorly specified and its composition varies from moment to moment. Hence, research into waste combustion is fundamental to rational incinerator operation and the evolution of innovative processes such as co-incineration and integrated incinerator/gas turbine plants. This paper reviews the current research activities at Sheffield University Waste Incineration Centre (SUWIC) in MSW incineration.

摘要:

A Green Certificate (GC) is a “document” that proves that a unit of electricity has been produced from a Renewable Energy (RE) source. Generators receive a certificate for each pre-defined unit of electricity produced from their RE scheme that is delivered to the electricity network. Electricity from RE schemes is indistinguishable from other electricity, so the certificate is used to represent the “renewableness” or the “greenness” of a unit of the renewable energy generation. A GC becomes a Tradable Green Certificate (TGC) when the mechanism allows trading of GCs as a means of meeting an obligation. Note that for practical purposes Green Certificates are more likely to be electronic documents than paper documents.
