Water-tube boiler - Wikipedia

The older fire-tube boiler design, in which the water surrounds the heat source and gases from combustion pass through tubes within the water space, is a much weaker structure and is rarely used for pressures above 2.4 MPa (350 psi). A significant advantage of the watertube boiler is that there is less chance of a catastrophic failure: there is

Scotch marine boiler - Wikipedia

Gases and smoke from the furnace pass to the back of the boiler, then return through the small tubes and up and out of the chimney. The ends of these multiple tubes are capped by a smokebox, outside the boiler shell. The Scotch boiler is a fire-tube boiler, in that hot flue gases pass through tubes set

Feb 19, 2015· There are a number of considerations to factor when determining the best boiler for your steam generation needs like operating pressure, steam pounds/hour output, demand fluctuation, general application requirments and total cost of ownership, etc. Two primary boiler types, the firetube boiler and the watertube boiler, are essentially opposite in design. The firetube boiler passes combustion

Petropedia - What is Fire Tube? - Definition from Petropedia

A Fire Tube is specially used in oil and gas production to suffice the heating needs of other large equipment such as gas production units, oil refineries, treaters and heaters. This tube is basically used to supply air to the burner, where there is a low-pressure environment containing burner fuel that reacts with the air and ignites.

Scotch Marine Boiler | Three Pass Wetback | Series 400

Three and four pass dry back boilers have tube sheets with large temperature variations and this results in premature tube failure and cracks in the tube sheets. Easy Access Since there is no large refractory rear door, one man can easily remove the rear cover plates for access to the tubes.

through the third pass tubes. The hot gas travels toward the upper portion of the rear head where it’s turned and directed through the fourth pass tubes. From there, after giving up most of the energy from the combustion process, the gas is directed into the stack and vented to the atmosphere. Figure 1-1: Firetube Cut-Away gAS TrAiN OiL pipiNg

Water for Power Plant Cooling | Union of Concerned Scientists

Oct 05, 2010· Wet-recirculating or closed-loop systems reuse cooling water in a second cycle rather than immediately discharging it back to the original water source. Most commonly, wet-recirculating systems use cooling towers to expose water to ambient air. Some of the water evaporates; the rest is then sent back to the condenser in the power plant.

The fire investigator should have a basic understanding of the potential role of natural gas as a fuel source, an ignition source, and a factor in fire spread. The fire investigator should also know the tests that may be required as part of the fire investigation when natural gas piping or equipment is involved.
