What is BS 845-1 – Thermal performance of boilers for heat transfer fluids about?
BS 845 is a series of British Standards that discusses industrial boilers and heat exchangers. The main objective of BS 845 is to provide best industry practices to demonstrate the performance and reliability of boilers and heat exchangers.
BS 845-1 is the first part of the BS 845 series that describes a concise procedure for conducting thermal performance assessments, using the indirect (losses) procedure, to give results within a tolerance of ± 2 percentage points 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 that 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.
Who is BS 845-1 - Thermal performance of boilers for heat transfer fluids for?
BS 845-1 on thermal performance of boilers for heat transfer fluids is useful for:
- Manufacturers of boilers and heat exchangers
- Boiler plants
- Quality control and testing authorities
- Engineers
- Local and national authorities
- Regulatory bodies
Why should you use BS 845-1 - Thermal performance of boilers for heat transfer fluids?
Steam boilers are distinguished by their construction, portability, tube types, fuel sources, and pressure output. A steam boiler absorbs the heat produced by combustion. Radiation, convection, and conduction are the three methods through which heat is transmitted.
BS 845-1 uses the indirect (losses) procedure, in which the heat input is measured or, if not possible, the thermal output and the losses are established.
BS 845-1 walks you through the test procedure and provides guidance on instrumentation requirements and calculations that help determine the thermal efficiency of boilers. As a result, you can demonstrate whether or not the boilers are fit for purpose.
Regular assessments in accordance with BS 845-1 can enable the boiler plant to be monitored in normal operation for optimum efficiency in the interests of fuel conservation.
