How do millivolt gas valves work?
A millivolt gas valve is used in a standing pilot type of appliance. In a normal application there are actually 2 valves in one. one valve controls gas flow to the pilot and the other part of the valve controls gas flow to the burner. The pilot burns on a device or devices that produce a small amount of electricity ( millivoltage ) some valves accomplish this with a thermopile producing energy for the pilot and the burner portions of the valve. others use a thermocouple to produce energy to keep the pilot open and a thermopile to produce the energy for the burner side of the valve. In a typical gas fireplace valve the pilot runs on 30mV ( millivolts ) and the burner runs on 500 mV. it sounds like alot but it's only .5volts. This energy creates an electromagnet that pulls the valve open against a spring. That is the fail safe and how the pilot safety function works, if for any reason the energy isn't present, the spring snaps the valve shut shutting off the gas. Millivolt valves are NOT field serviceable. They should never be disassembled as they will leak. Most issues with millivolt valves are caused by a simple lack of manufacturer recommended service and maintenance.
How can I troubleshoot a gas fireplace thermopile issue?
To troubleshoot a gas fireplace thermopile issue, first check for any debris or blockages in the pilot light or burner. Next, ensure the gas supply is turned on and the pilot light is lit. If the pilot light won't stay lit, the thermopile may need to be cleaned or replaced. You can also test the thermopile with a multimeter to check for proper voltage output. If these steps don't resolve the issue, it may be best to consult a professional technician for further assistance.
How long does it take to boil ml of water in a Bunsen burner?
8.30 minutes
What would happen to marble if the bunsen n burner had been turned off for several minutes?
If the Bunsen burner is turned off, the marble's temperature would gradually decrease as it loses the heat energy absorbed. The marble would eventually cool down to room temperature.
How long does it take to boil 150ml of water on a Bunsen burner?
It typically takes around 2-3 minutes to boil 150ml of water on a Bunsen burner, depending on the intensity of the flame and the efficiency of the burner.
What are some common issues to consider when conducting gas fireplace troubleshooting?
When troubleshooting a gas fireplace, common issues to consider include checking the gas supply, ensuring the pilot light is lit, inspecting the thermocouple and thermopile, cleaning the burner and ensuring proper ventilation.

How long does it take to boil 50 ml of water using a Bunsen burner?
Well, honey, it doesn't take a rocket scientist to figure this one out. Boiling 50 ml of water using a Bunsen burner should take around 1-2 minutes, depending on the intensity of the flame and the efficiency of your burner. Just keep an eye on it, and don't let it evaporate into thin air!
Where is the orfice on a dearborn heater?
Behind a hex cap next to the main burner valve.this is wrong...the orifice is located inside the burner you have to disassemble the valve from the burner in other words you have to take the whole thing apart takes about 15 minutes on a bad day
