Steam Calculators: Boiler Calculat

Calculation Details Step 1: Determine Properties of Steam Produced Using the Steam Property Calculator, properties are determined using Steam Pressure and the selected second parameter (Temperature, Specific Enthalpy, Specific Entropy, or Quality). The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow: Pressure = 471.9 psig

Understanding Combustion Efficiency and Combustion Equatio

Understanding Combustion Efficiency Combustion efficiency is a measurement of how well the fuel being burned is being utilized in the combustion process. This is different from the efficiency number produced on the analyzer, which is reflective of the total amount of heat available from the fuel minus the losses from the gasses going up the stack.

Natural gas pipe diameter, flow rate and pressure dro

Gauge pressure must be higher than 1 bar and lower than 100 bar. The pipeline should be longer than 1m. How is the calculation executed? The Calculator uses Renouard equation for calculation. It assumes that the temperature of the natural gas flow in long pipelines is constant.

Understanding Combustion Efficiency and Combustion Equatio

If the natural gas is burned with air, which contains 21% oxygen, 78% nitrogen and 1% trace gasses, the exhaust can also include carbon monoxide (CO), oxides of nitrogen (NOX, nitrogen + oxygen) and if sulfur is present in the fuel, sulfur dioxide, SO2 (Sulfur + oxygen).
