What is BS 3841-2 - Determination of smoke emission from manufactured solid fuels for domestic use about?
BS 3841-2 describes an electrostatic precipitator method and a dilution tunnel method for measuring the smoke emission rate from a manufactured solid fuel tested in accordance with BS 3841-1:1994.
Who is BS 3841-2 - Determination of smoke emission from manufactured solid fuels for domestic use for?
BS 3841-2 on determination of smoke emission from manufactured solid fuels for domestic use is useful for:
- Solid fuels industry
- Manufacturers of solid duels for domestic use
- Testing laboratories
- Health the safety bodies
- Environmental safety bodies
- Pollution control authorities
Why should you use BS 3841-2 - Determination of smoke emission from manufactured solid fuels for domestic use?
Smoke emissions from chimney and other applianced in domestic environment generae lot of harmfull emissions, having impact on the surrounding area as well as health. Therefore, measuring and collecting these smoke emissions is essential.
Electrostatic precipitator is used for the purpose of collecting and measuring the smoke from domestic appliances burning solid fuel. The precipitator collects the particulate matter from the total volume of flue gas produced by the fire during the test period.
BS 3841-1 describes the general procedure to be adopted for measuring the smoke emissions from solid smokeless fuels. BS 3841-2 describes procedures for measuring the smoke emission rate (in g/h) under the combustion conditions specified in Part 1.
BS 3841-2 provides the electrostatic precipitator method, which was developed for the purpose of collecting and measuring the smoke from domestic appliances burning solid fuel.
The total mass of smoke emitted during the test period is determined by weighing the precipitator at the beginning and end of the test.
BS 3841-2 provides guidance on carrying out electrostatic precipitator method for smokeemission rate measurement, dilution tunnel method for smoke emission rate measurement. Both methods specified in BS 3841-2 have been shown to be capable of measuring in the range 0.5 g/h to 30 g/h.
Comparison of results obtained by the dilution tunnel and electrostatic precipitator methods and calculation of in-stack concentration is also provided by BS 3841-2.
What’s changed since the last update?
BS 3841-2:1994 supersedes BS 3841:1972. BS 3841-2:1994 includes some technical
