2. Combitube - Wikipedia

   en.wikipedia.org/wiki/Combitube

   The Positube checks for air flow resistance on tube number two and is very helpful in checking proper Combitube placement when intubation is performed in noisy environments. The Combitube's ease of use makes it an option for use in the pre-hospital, emergency setting when advanced level providers capable of placing an endotracheal tube are not ...

3. Oil burner - Wikipedia

   en.wikipedia.org/wiki/Oil_burner

   The maintenance in a gun burner usually involves a replacement of the nozzle used to atomize the fuel, replacing the filter located at the air handler, replacing the fuel filter on the heating oil system from the tank, cleaning out any soot or deposits in the heat exchanger of the furnace, and ensuring the system is in good working order.

4. List of vacuum tubes - Wikipedia

   Continuously transmitting tubes: Maximum anode dissipation in W or kW in Class-C amplifier telegraphy; Pulsed transmitting tubes: Maximum peak anode current in A (number preceded by "P") Rectifiers: Maximum average anode current in mA; Thyratrons: Maximum average anode current: Less than 3 digits: in mA; 3 or more digits: 1st digit: =0 – in mA

5. Shell-and-tube heat exchanger - Wikipedia

   en.wikipedia.org/wiki/Shell-and-tube_heat_exchanger

   In shell-and-tube heat exchangers there is a potential for a tube to rupture and for high pressure (HP) fluid to enter and over-pressurise the low pressure (LP) side of the heat exchanger. [8] The usual configuration of exchangers is for the HP fluid to be in the tubes and for LP water, cooling or heating media to be on the shell side.

   Combination nozzle A low pressure fog nozzle (usually 120 to 150 lbf/in² or 820 to 1030 kPa that can be adjusted to produce a near straight stream. Also commonly referred to as a Taskforce tip (TFT). Compressed air foam system (CAFS) A water / surfactant (foam) mixture, with compressed air forced into the mix.

8. Ground-coupled heat exchanger - Wikipedia

   en.wikipedia.org/wiki/Ground-coupled_heat_exchanger

   If building air is blown through the heat exchanger for heat recovery ventilation, they are called earth tubes (or Canadian well, Provençal well, Solar chimney, also termed earth cooling tubes, earth warming tubes, earth-air heat exchangers (EAHE or EAHX), air-to-soil heat exchanger, earth channels, earth canals, earth-air tunnel systems ...

9. 833A - Wikipedia

   en.wikipedia.org/wiki/833A

   A pair of 833A's with adequate forced air cooling can deliver 1000 watts of CCS RF power operating as a class C amplifier plate modulated stage. A pair of tubes used in a class B modulator can deliver 1800 watts of "peak" AF power in ICAS service with speech, or 1600 watts in CCS service with music or high duty cycle operation. Two 833A's are ...
