Example of Nitrogen Electric Heater Power Calculation (1380KW)
Example of nitrogen electric heater power calculation, where the calculated power of the nitrogen electric heater is 1380KW.

Basic design conditions for nitrogen electric heater:

    Working pressure 0.35~1.50MPa (gauge pressure), design pressure 2.00MPa (gauge pressure); inlet nitrogen temperature of electric heater 35~230℃, outlet nitrogen temperature 200~430℃, outlet design temperature 450℃; normal gas flow rate 12750m³/h (standard condition), maximum gas flow rate 15000m³/h (standard condition).
    Nitrogen electric heater power calculation formula: P=E×C×ρ×Q×△T
Where: E—Safety factor, taken as 1.3 (recommended value);
     P—Power required for medium temperature rise, W; 
     C—Specific heat of medium, J/(g·℃);
