Equipment |
High Volume Sampler |
|
2. |
Description |
The high volume fly ash sampler is used to |
|
|
|
|
recover a representative sample of fly ash |
|
|
|
by traversing the boiler exit or air heater exit |
|
|
|
ducts over a short period of time. The flyash |
|
|
|
sample is collected by drawing the gas sample |
|
|
|
into the collection canister by an aspirator. |
|
|
|
Within the canister, the ash is separated from |
|
|
|
the gas by passing the sample through high |
|
|
|
temperature filtering paper. |
