The Johnston 3-pass boiler has large steam and water storage areas, high efficiencies and the ability to meet wide load demands. The three pass design can be manufactured up to a 2500 HP steam boiler. As well as the 4-pass design, the 3-pass maximizes heat transfer while minimizing the use of refractory – no expensive door repairs.
The Enertech Classic 3-Pass Wet Back Package Fire Tube Boiler is a high performance boiler unit with design parameters based on the generously built top of the line US boilers, suitable for firing bunker C oil, Diesel oil, LPG or Natural Gas. It is available in capacities from 60 to 1500 boiler horsepower (940 to 23,500 kg/h), with operating
The furnace represents the 1st pass through the boiler. Exhaust gasses from combustion then travel to the first reversal chamber. The gasses exit the reversal chamber and then enter the 2nd tube pass, second reversal chamber, 3rd tube pass, smokebox and finally the chimney. Water is heated by the heat from combustion and the resultant exhaust gasses.

Boiler is a two drum, bent-tube, "D" type Boiler. The line consists of three Models; "D", "DL" and "DLD" which vary only in size, dimensions, and capacity. All models are covered by this manual. The Boiler has a six-wall water cooled furnace. The inside and outside furnace walls, as well as
Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure

Apr 23, 2018 · Packaged boilers can be water tube or fire tube. These boilers are classified single pass 2 pass and 3 pass boilers. based on the number of times the hot combustion gases pass through the tubes of the boiler. Package boilers can be further classified to Wet back boiler and dry back boilers.
Watertube capacity with firetube efficiency. Each set of tubes that hot combustion flue gas travels through before making a turn within the boiler, is considered a "pass." A 3-pass firetube boiler design consists of three sets of horizontal tubes, with the stack outlet located on the rear of the boiler. A downdraft design keeps the cooler water from having an effect on the hot surfaces within the boiler.
• Package boilers are generally of shell type with fire tube design • High heat release rate in small combustion space More number of passes-so more heat transfer Large number of small diameter tubes leading to good convective heat transfer. Higher thermal efficiency Packaged Boiler
