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 is a large number of small-diameter fire
High Pressure Boilers. chapter 1. STUDY. PLAY. Scotch Marine boiler , vertical fire tube boiler. 350 PSI and 750 BHP. The higher the steam pressure, the higher the _____ of the water in the boiler. Boiling point. As Steam pressure in the boiler increases, there is …
The larger capacities of a steam and hot water boiler are powerful enough to support large-scale, high demand critical operations that see swings in steam demand. The water stored in the steam boilers allows for a much better response to changing steam demand from the plant than the single through design of a steam generator.

DRY BACK SCOTCH MARINE BOILERS Available in Steam or Hot Water Versions Two pass boiler design eliminates refractory baffles between flue gas passes. Minimum maintenance with rugged construction for extra-long life. Efficiencies allow for burning number 5 and number 6 oil with complete combustion with low heat release.
What is a Fire tube boiler? The universal type of steam boilers is the smoke tube or fire tube boiler where the heat and gases of combustion (from furnace) pass through tubes that are enclosed by water. While in water tube boilers, water passes through tubes.Mostly used boiler in small and medium industries with different fuels and steam pressure requirements.
2017-12-19 · * water converted into high pressure steam by transfer of heat from very high temperature combustion gases on water. If cocks A and D or steam passage is shut or choked, boiler pressure will press the water level in the glass higher than the real water level of the boiler. The water level indication in glass will, therefore, be incorrect.
2019-5-13 · A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam. The fire-tube boiler developed as the third of the
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.
