• Energy efficiency 30%-85%
  Currently, industrial machinery mainly uses resistance heating elements which can produce a large amount of heat radiated to the surroundings. Induction heating is an ideal alternative to solve this issue. The surface temperature of induction heating coil ranges between 50ºC and 90ºC, the heat losses are significantly minimized, providing energy savings of 30%-85%. The energy saving effect is therefore more obvious when the induction heating system is used in high power heating equipment.
• Safe
  Using induction heating system enables the surface of the machine to be safe for touching, and that means it can avoid burn injuries which often occur in machines that use resistance heating elements, providing a safe workplace for operators.
• Fast heating, high heating efficiency
  Compared to resistance heating whose energy conversion efficiency is approximately at 60%, the induction heating is over 98% efficient at converting electricity to heat.
• Lower workplace temperature, higher operation comfort
  After using induction heating system, the temperature of entire production workshop is lowered by more than 5 degrees.
• Long service life
  In contrast to resistance heating elements that have to long-lasting work at high temperature, the induction heating works at near ambient temperature, therefore efficiently prolonging the service life.
• Accurate temperature control, high product qualification rate
  The induction heating provides low or no thermal inertia, so that it will not cause the temperature overshoot. And the temperature can remain at set value of 0.5 degree difference.

Example: Project of Pyrolysis for Flue Gas Denitrification

• Name: induction heating for pyrolysis
• Medium to be heated: flue gas after denitrification, water vapor 26%, dust <20mg/Nm³
• Flow rate: 500Nm³/h
• Heat carrier: stainless steel pipeline
• Starting temperature: 180-200ºC; End temperature: 350ºC
• Heating time: 3600s

Calculation formula
Q=CM(t2-t1)
Q=W=Pt
Specific heat capacity CP of flue gas: 1030J/kg*ºC
Specific heat capacity CP of 0.1MPa water vapor: 1850J/kg*ºC
P1=1030J/kg*ºC×(350-180)ºC×(1.29*500*0.74) kg÷3600s=23215.34W≈23kW
P2=1850J/kg*ºC×(350-180)ºC×(0.47*500*0.26) kg÷3600s=5337.76W≈5kW
Theoretical total power P=P1+P2=23kW+5kW=28kW
Calculating under continuous operation with 1.5 times load, the actual power is 28kW*1.5=42kW, one 50kW stainless steel induction heating system is recommended.
