BS 845-1:1987

This standard BS 845-1:1987 Methods for assessing thermal performance of boilers for steam, hot water and high temperature heat transfer fluids is classified in these ICS categories:

• 27.060.30 Boilers and heat exchangers

This Part of BS 845 describes a concise procedure for conducting thermal performance assessments, using the indirect (losses) procedure, to give results within a tolerance of ± 2 percentage points¹⁾ for boilers for steam, hot water or high temperature heat transfer fluids and for presenting the results in tabular form. Test results are based on either the gross or the net calorific value of the fuel.

This concise procedure provides a convenient means for assessing boilers which are thermodynamically simple, i.e. having a single major source of heat input and a simple circuit for water, steam or high temperature heat transfer fluid, and that do not condense moisture out of the flue gases.

NOTE The titles of the publications referred to in this standard are listed on the inside back cover.

A concise but complete test method, at minimum cost, for assessing the thermal performance of boilers, generally of output greater than 44 kW which are thermodynamically simple and fired by solid, liquid or gaseous fuels.
