BS 3407:1982

What is BS 3407 - Guide for assessing coke screening plant about?

BS 3407 provides guidance on assessing coke screening plants, both new and those to which major alterations have been carried out, including mobile plants.

BS 3407 describes methods that can be used to satisfy buyer and seller that the plant is capable of meeting the requirements agreed between them and to indicate the effectiveness of separation of the specified coke into required fractions.

For the purposes of BS 3407, main screening plants are considered to consist of screens, storage hoppers, anti-breakage devices, and debreezing screens, together with inter-connecting conveyors and chutes. Mobile screening plants are those which are commonly used to remove undersize material from graded coke after ground storage.

Note: BS 3407 requires frequent reference to BS 1016-18 and BS 1017-2 and it is based on the assumption that the relevant requirements of these standards are complied with.

Who is BS 3407 - Guide for assessing coke screening plant for?

• Coke ovens
• Coke storage hoppers
• Coke producing plants
• Relevant compliance authorities

Why should you use BS 3407 - Guide for assessing coke screening plant?

BS 3407 gives guidance on the testing of new coke screening plants or plants where major alterations have been carried out, and to show the effectiveness with which the specified coke is separated into the required size fractions. In coke screening practice, the required size fractions or grades refer to coke at the outlet of storage hoppers or at the end of a boom loader or at other such points where coke is finally discharged from the plant, and therefore the tests will normally include the effect on the coke of the passage through the hopper.  

BS 3407 specifies different clauses as follows:

• Clause 4 gives guidance on methods of assessing the effectiveness with which a screen separates coke into the required sizes.
• Clause 5 gives a description of how the test is to be carried out and
• clause 6 some procedures for obtaining the required technical data for evaluating the plant.

Appendix A shows the number of increments to be collected for moisture determination, Appendix B sets out the way in which the results should be recorded and Appendix C gives a method for calculating input data when testing mobile plant.

BS 3407 is intended for application at coke ovens but would be equally applicable to any coke producing plant or manufactured fuel works.

What’s changed since the last update?

BS 3407:1982 supersedes BS 3407:1969. The main technical change from the BS 3407:1969 concerns the efficiency of screening and the opportunity has been taken to align it with BS 1016-18, which has superseded BS 1293 and BS 2074.
