This work was undertaken in collaboration with the Department of the Environment and a group of industrial sponsors in view of prospective European standards to limit emissions of nitrogen oxide (NOx) and carbon monoxide (CO) from domestic gas and oil-fired central heating boilers. This report is a summary of the information currently available from some 30 countries, and seeks to provide the reader with a brief overview of the findings of some 40 years research and development. With the world-wide concern over topics such as pollution, acid rain and ozone depletion, it is inevitable that all sources of pollution, large or small, are being, and will continue to be, scrutinized. There is mounting environmental pressure to reduce emissions of all types, and central heating boilers, although individually small, can be a significant local source of emissions, particularly NOx and CO2. The exposure limits to NOx and other pollutants are continually being reduced, which in turn are likely to also drive emissions limits down.
As the commercial advantage in marketing products incorporating low NOx technology increases, most low NOx research has been and is likely to remain confidential, or of a commercially sensitive nature. In particular, in common with the associated boiler emissions project at BSRIA, emissions measurements at other research establishments over the years, whilst building an extensive fund of knowledge in NOx emissions, are all confidential, and the results are not available to third parties. The effects on the environment of each of the major boiler emissions can be inter-related, and are also dependent on meterological and seasonal variations. They are also inter-related with other pollutants, both in concentration and type, and the environmental effects of pollutants can be long-lasting. A number of contact points for further information have been established, and updated information on legislation in several countries has been promised when it is available. Legislation on emissions is not static, and limits will tend to reduce to the minimum attainable by available technologies.
