Pilot lights

Naked flames (e.g. Bunsen burners, welding torches, blow lamps, furnaces, pilot lights, matches, glowing cigarettes or embers). 

Pilot Light. This is a small continuously operated flame at the end of the blooey line, and it will ignite any natural gas encountered while drilling. 

Burn Pit. This pit is at the end of the blooey line and provides a location for the cutting returns, foam and for natural gas or oil products from the subsurface to be ignited by the pilot light and burned off. The burn pit should be located away from the standard mud drilling reserve pit. 

These four main types of apparatus being defined, (scientiste and manufacturers have let their imagination go in order to create apparatus). There are now about ten models, which differ by the volume of liquid used (from 2 cm to about 70 cm, the metal used for the cup (brass, aluminium), the heating mode (water bath, Bunsen burner, electrical), the type of gas used by the pilot light (natural gas, butane), the level of complexity of automatic controls some apparatus equipped with several cups can actually be programmed in order to make measurements automatically without the help of the operator. The liquid can be shaken manually or, thanks to an electrical motor, the ignition can be manual or automatic.

Never use excessive heat for drying. I have heard of nitro propene burning faster than gunpowder due to excessive heat. Personally, 1 feel this could have been caused by a nearby pilot light that was left burning. 

The qualifications tests consists of checking the transmission of the one-bit binary information sent by the controller to the contactors, relays, electrovalves, pilot lights, and other digital outputs of the system.

Today, burner manufacturers have access to all kinds of designs for pilot lights, to fit all shapes and sizes of burners and burner ports and draft systems from the smallest breeze to gale-force winds—there is no longer any excuse to operate without pilot lights installed and working. 

One of the most common safety trips is the automatic fuel-gas shutoff. We have this at home on our furnaces. We ignite the pilot light manually. The pilot light heats a thermocouple. The milliamp output from this thermocouple opens the fuel-gas valve to the main burner. The gas in the main burner is ignited from the pilot-light flame. Should the heat from the pilot light diminish below a certain point, the fuel gas to the main burner, as well as to the pilot light, will be shut off.

Transformer ignition circuit for bomb calorimeter. The switch is a momentary-contact push switch that is only on when it is held down. Release the switch if ignition does not occur after about 5 s (the pilot light will indicate when the fuse wire bums through). The choice of resistor R will depend on the type of calorimeter and the length of fuse wire to be used (a current of 3 to 4 A is desired).
