Our two-pass, three-pass or four-pass Scotch Marine(Fire Tube) boilers are available in dryback, wetback, steam or hot water versions; from 15 to 800 hp with pressures to 300 psig. Hurst Scotch Marine boilers are rated to 81% minimum efficiency.
atural circulation water tube and fire tube boilers (Figs. 1 and 2) are widely used in the chemical process industry. These are preferred to forced circulation boilers (Fig. 3) where a circulation pump ensures flow of a steam/water mixture through the tubes. In addition to being an operating expense, a pump failure can have erious s
h) Identify measurement locations and verify access. i) The most common flue gas measurement location is immediately downstream of the steam generation section of a water-tube type boiler. For a fire-tube type boiler the flue gas sample is most commonly taken as the exhaust gases exit the boiler proper. Establish tune-up timeframe. 39.
Maintaining a good flame in a boiler is the key to a good boiler performance. Unstable flame is always a threat for boiler furnace explosion, which can lead to a large outage of boiler and loss. There are many causes that can contribute to boiler flame failure. Hence it has become a practice of all boiler designers to interlock purging the boiler with boiler start-up.
According to flow of water and hot gases: 1. Water tube. 2. Fire tube. In water tube boilers, water circulates through the tubes and hot products of combustion flow over these tubes. In fire tube boiler the hot products of combustion pass through the tubes, which are surrounded, by water. Fire tube boilers have low initial cost, and are more

Fire tube boilers are useful for small demands of steam and water tube boilers are useful for industrial level usage. To cut short the main purpose of boiler is to boil a liquid mostly the water in order to generate the steam for serving the purpose of heating a building or running an equipment through pressurized steam or pressurized water.
Shell and tube boilers are also referred to as fire tube or smoke tube boilers. Fire tube boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to steam circulates. Fire tube boilers, typically have a lower initial cost, are more fuel efficient and easier to operate.

Boiler operators and technicians should pay close attention to three key safety devices to protect personnel, equipment, and the facility: Safety valves. The safety valve is the most important safety device in a boiler or domestic hot-water system.
Alternative water-tube boiler layouts. The following layouts work on the same principles as other water-tube boilers, and are available with capacities from 5 000 kg/h to 180 000 kg/h. Longitudinal drum boiler. The longitudinal drum boiler was the original type of water-tube boiler that operated on the thermo-siphon principle (see Figure 3.3.5).
Fire tube steam boilers are designed for the purpose of industrial scale heat exchange in order to heat saturated liquid entering the control volume to a saturated gas. Exiting gas leaving the control volume may experience a pressure drop when returning to atmospheric pressure. Three pass fire tube steam boilers are composed of a cylindrical hull filled with thermal insulation in which a
Scale builds up over a longer period of time and also contributes to boiler inefficiency. Heat loss of 8% and increased fuel consumption of 2% will result from only 1/32" (0.8mm) of scale in the boiler tubes. In a water tube boiler, water runs through tubes that are surrounded by the heating source. Because the water is heated to very high

3. Scotch Fire Tube Boiler Design. The scotch fire tube boiler design is most commonly referred to as the scotch marine boiler. With this design, the furnace is a big diameter tube located inside of the boiler. The furnace and boiler are circumferenced by water. Some of the larger, older scotch boilers would have two or even three different
The common steam locomotive boiler is a horizontal straight fire tube boiler with riveted cylindrical boiler courses, a stayed internal firebox at the rear, and a smokebox at the front. Operating pressure ranges up to 300 psi. The boiler shell is made up of cylindrical sections or courses which may be straight or tapered.
The HP boiler worked at approx 850 psi (5.86 MPa), and the low-pressure boiler at 200 to 250 psi (1.38 to 1.72 MPa). The UHP and HP boilers were of a water tube design, while the LP boiler was a fire tube boiler typical for steam locomotives. The LP cylinders were driven with a mixture of the HP cylinder exhaust and the LP boiler output.

Shellmax is a packaged, three-pass smoke tube, with fully wet back boiler. Shellmax comes in two series - SMDL for burning light oils & gas and SMDH for burning heavy oils. It can also be customised to a completely skid mounted unit on customer demand.
A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7-2,000 kPa or 1-290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
Meaning if the pressure drops on a fire tube boiler, it takes longer to come back up than on a similarly rated water tube boiler. Fire tube boilers typically have lower operating and maintenance costs, have easier access to the fire and water sides for inspections, and its much easier to replace tubes on a fire tube than a water tube.
Comparison between Fire Tube and Water Tube Boiler can be done in 14 aspects. Those aspects are operating pressure, passage of material type in tubes, rate of steam generation, handling of load fluctuation, floor area requirement, efficiency, operator skills, design, maintenance cost are listed below in the tabular form.

the Boiler Master), fuel flow and air flow controllers in manual mode, and set their outputs to the required ignition positions. The ignition sequence is then initiated by closing the fan switch. The programmer will automatically put the boiler into a pre-purge mode, with the required amount of air flow, for a specified time period.
The boiler consists of a shell, a tube sheet on each end of the shell, and tubes connecting the two tube sheets. The boiler is mounted above a steel or masonry furnace. The products of combustion leave the furnace and are directed through the tubes at one end of the boiler.
