Running fire

Running Fire - Is a fire from a burning liquid fuel that flows by gravity to lower elevations. The fire characteristics are similar to pool fires except it is moving or draining to a lower level. 

Operators understand the importance of maintaining fired heaters in a safe and rehable condition. The response from operators to this priority could go to another extreme run fired heaters with too much excess air. The result of much excess air is much reduced flame length and thus the risk of flame impingement is minimized. 

The sidewall sampling tool (Sl/VS) can be used to obtain small plugs (2 cm diameter, 5 cm length, often less) directly from the borehole wall. The tool is run on wireline after the hole has been drilled. Some 20 to 30 individual bullets are fired from each gun (Fig. 5.35) at different depths. The hollow bullet will penetrate the formation and a rock sample will be trapped inside the steel cylinder. By pulling the tool upwards, wires connected to the gun pull the bullet and sample from the borehole wall. 

The purpose of the well completion is to provide a safe conduit for fluid flow from the reservoir to the flowline. The perforations in the casing are typically achieved by running a perforating gun into the well on electrical wireline. The gun is loaded with a charge which, when detonated, fires a high velocity jet through the casing and on into the formation for a distance of around 15-30 cm. In this way communication between the wellbore and the reservoir is established. Wells are commonly perforated after the completion has been installed and pressure tested. 

Burning clothing. Prevent the person from running and fanning the flames. Make the victim he down on the floor, or throw him (her) down if necessary, and wrap the fireproof blanket firmly around the ignited clothes until the fire is extinguished. 

A difference between these firing methods may also be manifested in the initial fuel cost. For efficient operation of a spreader-stoker-fired boiler, the coal must consist of a proper mixture of coarse and fine particles. Normally, double-screened coal is purchased because less expensive run-of-mine coal does not provide the optimum balance oFcoarse and fine material. 

In the horizontal-tube box heater with side-mounted convection tube bank, the radiant-section tubes run horizontally along the walls and the flat roof of the box-shaped heater, but the convection section is placed in a box of its own beside the radiant sec tion. Firing is horizontal from the end walls. The design of this heater results in a relatively expensive unit justified mainly by its abihty to burn low-grade high-ash fuel oil. Duties are 53 to 210 GJ/h (50 to 200 10 Btu/h). 

Indirect Heating If the process material cannot tolerate exposure to the combustion gas or if a vacuum or an atmosphere other than air is needed in the furnace chamber, indirect firing must be employed. This is accomplished in a muffle furnace or a radiant-tube furnace (tubes carrying the hot combustion gas run through the furnace). 

Vacuum transfer into reactor, drum or feed tank runs dry, resulting in air being pulled into vessel, creating flammable atmosphere. Potential for fire/explosion. 

In the third e.vample, the line terminates at 53%. This means DO NOT run this pump at less than 53% of the BEP. 53% of 4500 gpm is 2385 gpm. Because this is a firewater pump and because firemen need to throttle the nozzles on their fire hoses, then we need to install a pressure relief valve on this system with a discharge bypass line so that the pump dumps the restricted water (less than 2400 gpm) back into the suction tank or lake. If not, this firewater pump is likely to suffer bearing failure during an emergency. 

Early U.S. experienee in residual operation dates baek to the early 1950s. Several eompanies adapted gas turbines to run on residual fuel for loeo-motive applieation. Operating with a low inlet temperature 1350 °F (732 °C), low-sulfur residual eorrosion was limited however, it was noted that any inerease in firing temperature was aeeompanied by serious eorrosion.

The fire spreads easily by, e.g., running liquid fire, a pool fire, a fire ball, heat radiation or thermal lift (convection).

Fire and smoke damper. A device used to isolate one area of a building from fire or smoke in another, or one part of a duct run from fire or smoke in another. The device is mechanically or electrically operated in case of fire. 

The,se heaters represent a low-cost, low-ot ficiency design that requires a minimum of plot area. Typical duties run from 0.5 to 200 MMBtu/hr. Six iy[)cs of veitical-tube-fired heaters are shown in Figure 3-20. 

The radiant section tube coils of horizontal fired heaters are arranged horizontally so as to line the sidewalls and the roof of the combustion chamber. In addition, tliere is a convection section of tube coils, winch are positioned as a horizontal bank of tubes above the combustion cham her. Nonnally the tubes are fired vertically from the floor, but they can also be fired horizontally by side wall mounted burners located below the tube coil. Tins economical, high dficiency design currently represents the majority of new horizontal-tube-t1icd heater installations. Duties run from 5 to 250 MMBtu/hr. Six types o) horizontal-tube-fired heaters arc-shown in Figure 3-21.
