LOW PRESSURE STEAM AND HOT WATER THRU-THE-DOOR BOILER. EASCO Series SM5, Modified Scotch Marine, Horizontal Firetube 3 Pass Water backed Boilers are manufactured for use in low-pressure steam (15 PSIG) or hot water (30 to 60 PSIG) standard applications, providing efficient operation and low-cost maintenance. 20-150 Boiler Horsepower.
The Johnston 509 Series offers an efficient 4-pass boiler (50-1600 HP) configuration which maximizes heat transfer, while at the same time eliminating tube sheet stresses and costly maintenance repairs that are common with dry backed designs, as well as a 3-pass boiler (1800-2500 HP) with its high steam and water storage areas, high efficiencies, rugged construction, and its ability to keep up
Boiler shell is 5/16" thick boiler plate 30-40 HP / 3/8" 50-125 HP. Twin boiler tube sheets are 1/2" thick boiler plate. Insulation is 2" ceramic wool and is lagged with 22-gauge boiler jacket. Extra heavy 4" channel iron boiler skids. Designed to last with special industrial grade features. Couplings are 3,000 psi. Flanged, detachable front
Apr 15, 2021 - 15ton fire tube steam boiler is a traditional three-pass, wet-back horizontal firetube boiler. The first pass flows through the furnace from front to back. The furnace is corrugated to maximize efficiency while also minimizing thermal stress.

3 Pass Wet Back Boiler (Manual Fired) It features a large water capacity allowing it to satisfy high demands for steam in a very short time. The large evaporation of water droplets even during repeated demands for steam as often happens during industrial use.
This 3D model shows all major components associated with a typical three pass fire tube boiler, these include: Shell – fired pressure vessel. Burner – used for combustion. Corrugated furnace – where combustion occurs.
Earlier generation boilers used to be dry back. Thus wet back boilers ensure lesser radiation losses and hence save fuel. The layout of the tubes involves the number of passes the tube will make to pass the heat from the boiler furnace before being discharged. These can be two- pass and three pass boiler.
Figures 3.2.1a and 3.2.1b show a typical two-pass boiler configuration. Figure 3.2.1a shows a dry back boiler where the hot gases are reversed by a refractory lined chamber on the outer plating of the boiler. Figure 3.2.1b shows a more efficient method of reversing the hot gases through a wet back boiler …

BOILER TYPES FOR STEAM APPLICATIONS One weakness of a multi-pass Firetube boiler is a problem called "Thermal Shock". This is actually not a shock, but a difference in thermal expansion and contraction caused by the furnace, tubes and shell heating and expanding at different rates, causing high stresses and fatigue failure.
Oct 31, 2016 · Ever wonder how your boiler is creating steam? Today on the Boiling Point, Ritchie talks with Steven Taylor about how a firetube steam boiler works. Boiler's
A "Scotch" marine boiler (or simply Scotch boiler) is a design of steam boiler best known for its use on ships. Sectional diagram of a "wet back" boiler. The general layout is that of a squat horizontal cylinder. One or more large cylindrical furnaces are in the lower part of the boiler shell. Above this are many small-diameter fire-tubes.
Jun 24, 2019 · The output of a 10 ton boiler is 7 million kcal. Formula for calculating fuel consumption. Fuel consumption = boiler output ÷ fuel calorific value ÷ boiler thermal efficiency. According to the above method, the user can calculate the gas consumption of the gas steam boiler according to the various values provided by the boiler manufacturer
The top tube sheet in a steam boiler can be above or below the water line. When it is above, it is called a dry-top and when it is below, it is called a wet-top. A vertical boiler has a small "footprint" and can be installed in boiler rooms with limited space. Vertical boilers are very popular in the dry cleaning industry.
