  • APPENDIX A: HALON USE BY THE NAVY | Fire Suppression

    The halon 1301 agent is in liquid form in cylinders, pressurized by nitrogen at 600 psi. The nitrogen is required to provide adequate cylinder pressure to discharge the halon in 10 seconds and to provide sufficient nozzle pressure to ensure proper distribution of the agent in the compartment.

    Feb 21, 2014 · There's more to selecting the right grease than you might have thought. By Ken Bannister, Contributing Editor Whenever I deliver a Lubrication Fundamentals workshop, I ask attendees to close their eyes and "picture" a lubricant. Most have reported the simultaneous appearance of two distinct images during this exercise: one is a container of liquid oil, …

    Pressure sensors measure pressure in a gas or liquid in pounds per square inch (psi). Low pressures are typically measured in inches of water. Pressure can be generated by a fan, a pump or compressor, a boiler, or other means. Pressure controllers use bellows, diaphragms, and a number of other electronic pressure sensitive devices.

    Mar 29, 2011 · The enthalpy is the difference between boiler water temperature and boiling temperature, multiplied with the specific heat and density. Since steam boilers are under pressure, differential pressure transmitters (e.g. ABB type 266MST) must be used for level measurement in order to compensate for the vessel's overpressure.

    The ETC1021 Gas Pressure Sensor is installed between the two gas isolating valves on the gas train. Once installed the sensor can be used as part of the gas valve proving system and can provide high and low level alarm and interlock functions. Because the sensor is self-checking, the need for mechanical pressure switches is eliminated. The ETC1030/1034 & ETC1040/1044 are self-checking steam pressure and temperature sensors.

    Pressure. The ratio of force to area. Atmospheric pressure at the surface of Earth is in the vicinity of 15 lbf/in. 2 (1.0 × 10 5 Pa). Pressures in enclosed containers less than this value are spoken of as vacuum pressures; for example, the vacuum pressure inside a cathode-ray tube is 10-8 mmHg, meaning that the pressure is equal to the pressure that would be produced by a column of mercury

    The steam is then cooled and collected into an ice bath maintained at 0°C. The nozzle serves to isolate the high pressure in the boiler from the low pressure in the ice bath and may stabilize the steam flow. Accordingly, the steam is allowed to maintain a steady dynamic state for data acquisition purposes.
