Show .- which this programme should tOllOW, and shares, along with an international group of university departments, the interpretation and ultimate utilisation of the information generated. This basic programme is known as the "Core Research Programme" of the IFRF. At the present time the Core Programme is concerned with: • studies on the scaling of natural gas burners intended primarily for natural gas fired industrial boilers • the development and application of advanced laser based diagnostic techniques for the analysis of flames and particle and droplet sprays. • the development and application of mathematical models for the prediction of combustion and the emissions of pollutants such as NOx These programmes are well described in the latest Foundation Triennial Report [1], and are co-funded by a number of organisations ~cluding the European Community through the JOULE programme, the Gas Research Institute of the USA, and the Netherlands Agency for Energy and Environment, NOVEM. Using the techniques developed within the Core Research Programme in addition to the classical flame research techniques developed over the years at IJmuiden, the Foundation undertakes a parallel research programme, primarily oriented towards applications in industry. The larger part of the Applications ·Research Programme is concemed with advanced pulverised coal burners for utility boilers and the possibility to predict the effect of burner design and operation, and coal property variation upon the performance of such burners. Recent results from this International Energy Agency coal combustion programme, in which the participating coutries are Canada, Germany, the Netherlands and the United. Kingdom, are also presented extensively in Reference 1. The present paper is more concerned with industrial processes, such as glass tanks, cement kilns and industrial boilers, with an initial emphasis upon the firing of more conventional fuels such as natural gas and pulverised coal. However, the fuels discussed within the paper"' reflect the growing trend · towards the firing of less conventional fuels, leading to the development of combustion systems for renewable fuels. Initially results are presented on the firing of so-called bio-oils, leading into the most recent work Concerned with the development of combustion systems for the co-firing of biomass and waste materials, with pulverised coal, in an experimental combustion systems designed to simulate conditions in the combustion . chamber ·of a utility boiler. This last programme is part of a large · European C<H>peration supported by the European Community within the APAS progra~e . . |
