Flame rectification is DC electrical circuit that sends a very small voltage (rated in micro amps) from the furnace electronic board up through the pilot electrode. When pilot flame is established the flame acts as a path (conductor) which allows the DC current to flow from the flame rod to ground completing the circuit. This completed signal tells the electronic board it's ok to allow the main gas valve to open . Now your furnace pilot, or hot surface ignitor will start the main flame . To put it simple, flame rectification is an electronic way to prove pilot flame before opening the main burner gas valve. It's a safety circuit to prevent the main burner gas valve from opening if there isn't apilot flame, or hot surface ignitor established.

What is uncontrolled rectifier?
Uncontrolled rectification is rectification whose baise is not controlled by a gate signal.
What is the rectification efficiency of a half wave rectifier?
40.56%
What are the advantages of a simple circuit?
easy rectification of any component have any problem.current flow analysis is easy.
Formula how to calculate voltage ripple peak to peak?
For Half wave rectification: Vr(HW) = I/(C*F) HW= Ripple Voltage I = Direct Current C= Capacitance F= Frequency of the ac line. For full wave rectification: Vr(HW) = I/(2*C*F)
Why is it required to vary the field current in only one direction while performing the open circuit test on dc generator?
rectification to the negative voltage
How does flame rectification works in a gas furnace?
AC voltage(at least 90vac) pass through the flame sensor and the ionization of the flame creates or rectifies the voltage to DC and a small microamp that can be measured with a meterl.
What can diodes be used for besides rectification?
Besides rectification, the diode can be used as a switch.
What is uncontrolled rectifier?
Uncontrolled rectification is rectification whose baise is not controlled by a gate signal.
What are the modes of rectification?
Rectification mode makes the power conversion process more efficient.
What is rectification and which power supply provides a smoother form of rectification with less fluctuation?
Rectification is the process of converting alternating current into direct current. The smoothest power supply is a 'switched mode' supply.
What is Rectification of errors?
Rectification of error is a sum in commerce.In this sum we rectified the errors in preparation of journal,ledger and trial balance.
What is the Conclusion on rectification?
Rectification is the process of making something right or correcting errors. It is important in ensuring accuracy and integrity in various processes, such as financial transactions or data collection. Proper rectification can help prevent misunderstandings, improve efficiency, and maintain credibility.
What is the rectification efficiency of a half wave rectifier?
40.56%
What changes AC power to DC power?
Rectification.
Alternating current can be changed to direct current by?
by rectification
What does rectification mean?
To put something right, to correct.
Can a half wave rectification circuit be used to power radio receivers?
Of course. It's not as efficient or noiseless as full-wave rectification, but it's certainly usable as a source of DC.
