Calculation formula for boiler soot:
\(Q=G \times A \times ηA \times (1-η)\)
In the formula:
G——the amount of coal consumed;
A - ash in coal;
ηA——the percentage of fly ash in coal that accounts for ash; its value is related to the combustion mode, see the table below;
Η——dust removal efficiency; 55% for the water bath, 90% for the ceramic tube, 80% for the cyclone, and 99% for the bag;
Percentage of fly ash in coal as a percentage of ash (Environmental Statistics Manual)
| Furnace type | ηA | Furnace type | ηA |
|---|---|---|---|
| Hand burner | 15-25 | Boiling furnace | 40-50 |
| 链条炉 | 15-25 | Pulverized coal furnace | 75-85 |
| Reciprocating furnace | 20 | Vibration grate | 20-40 |
| Coal smelter furnace | 25-40 |
