This is the first of three essential reference volumes for those concerned with the installation and servicing of domestic and industrial gas equipment. This volume explains the basic principles underlying the practical and theoretical aspects of installing and servicing gas appliances and associated equipment, from the basics of combustion, to burners, pressure and flow, transfer of heat, controls, as well as materials and processes, electrical aspects, and metering and measuring devices. The revised fifth edition is brought fully up to date with current Standards and legislation to reflect recent developments in industry, in line with requirements of the ACS Certificates of Competence and NVQs. Covering both natural gas and liquefied petroleum gas, the many illustrations and worked examples included throughout the text will help the reader to understand the principles under discussion. Volume 1 of the Gas Service Technology Series will enable the reader to put into practice the safe installation and servicing procedures described in the companion volumes: Domestic Gas Installation Practice (Volume 2), and Industrial and Commercial Gas Installation Practice (Volume 3). Combining a comprehensive reference with practical application in real-world engineering contexts, Volume 1 provides an essential handbook for all aspects of fundamental gas servicing technology, ideal for both students new to the field as well as professionals and noneoperational professionals (e.g. specifiers, managers, supervisors) as an ongoing source of reference. * Comprehensive reference combined with practical application, an essential handbook for gas service technology * Fully updated in line with the latest changes to standards, NVQs and ACS Certificates of Competence * Hundreds of line drawings and photographs maximise accessibility of the text, enabling readers to easily recognise the appliances under discussion
