Main point

Coal handling dust and ash handling dust should not be merged into one unspecified material description. The source process and the actual material properties define the information an equipment designer must review.

02

Information to record

Create a separate duty sheet for each extraction or transfer point. Record material identity, available analysis, operating hours, airflow basis and collection destination. Identify changes in fuel, process or moisture that may make one historic sample unrepresentative of current production.

Review and acceptance

Ask the project engineering team to define the required material assessment and compare each proposed collector against the correct duty. Keep performance requirements and handling interfaces explicit. Do not transfer a general claim about power-station baghouses into an unconditional commitment for every coal or ash stream.

04

FAQ: Can one dust sample cover every collection point?

Only if its representativeness for the stated duties has been established.

05

FAQ: Should reclaimed dust destination be specified?

Yes. The destination and transfer interface are part of the proposed system boundary.
