This title describes a study carried out on 14 boiler installations under site conditions by monitoring flue gas oxygen content and temperature together with ambient air temperature to enable the combustion loss to be calculated. By undertaking the tests on boilers in both clean and dirty conditions, and recording data every minute over a period of two to three days, representative mean combustion loss figures were obtained. The combustion loss was calculated according to BS DD65 "Methods of type testing heating boilers for thermal performance. Part 1. Direct Method". The results of the study indicate the problems of producing accurate information about the performance of boiler plant under working conditions. Combustion loss figures ranged from 14.99 per cent to 29.33 per cent. Efficiency changes ranged from + 4.98 per cent to - 3.31 per cent but most changes were less than 2 per cent. The book finds no firm evidence of improved performance after maintenance and suggests further guidance is necessary on the level and frequency of maintenance required, together with some means of showing that adequate maintenance has been carried out.
