### Conversion of Existing Coal-Fired Boilers to Natural Gas

several boiler parameters responsible for the unit and steam temperature derates, which include boiler/burner technology and furnace he at input/plan area ratio. Boiler natural gas feasibility studies are required to determine the effects of burning natural gas in a coal -fired boiler.

### Understanding Coal Power Plant Heat Rate and Efficiency

Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C (Shen and Cheng, 2004).

Conversions Gross/Net (per ISO, for As Received figures) kcal/kg: Net CV = Gross CV - 50.6H - 5.85M - 0.191O MJ/kg: Net CV = Gross CV - 0.212H - 0.0245M - 0.0008O Btu/lb: Net CV = Gross CV - 91.2H - 10.5M - 0.34O where M is % Moisture, H is % Hydrogen, O

### Challenges when Converting Coal-Fired Boilers to Natural Gas

Mar 11, 2019 · Boiler coal consumption calculation formula = boiler power ÷ coal heat value ÷ boiler thermal efficiency. Of course, the boiler unit conversion is uniform when calculating. Taking a 10 ton szl series coal-fired boiler as an example, assume that the anthracite calorific value is 6500kcal/kg, and the coal consumption is 6000000 kcal / h ÷ 6500kcal / kg ÷ 85% = 1086kg / h.
