Operating Limits — Boilers heat water under pressure. When water is heated above its boiling point it can flash to steam if the pressure is removed. In addition, “dry firing a boiler” (applying heat to a boiler with inadequate water inside) can result in an extremely destructive and hazardous condition caused by the rapid and potentially explosive buildup of extreme pressures and temperatures
In this new edition the book has been updated throughout with new material on welded boilers, various types of water tube boiler, rotary air heater, water level alarm, consolidated type safety valve, hydraulic testing and various aspects of survey, maintenance and operational problems.
Water wall and screen tube headers were subsequently found to be blocked solid with plugs of steel which had formed when the molten boiler tubes and run back into their holes. In the foregoing incidents with water tube boilers the source of heat responsible for the overheating has been the boiler burners.
Efficiency in boilers and beyond Steam production and waste heat recovery . 2 In 2007, a new generation of MISSION boilers with reduced environmental impact is launched: the self-cleaning MISSION TCi (Turbo Clean Intelligent) series. The boilers are now delivered as one complete unit. In 1988, Aalborg Marine Boilers & Engineering acquires Dansk Fyrings Teknik A/S, Odense, Denmark …
Boilers. On the Patriot State, steam is produced for propulsion and other requirements by two Babcock and Wilcox two-drum, oil fired marine water tube boilers, that are capable of producing 108,000 lbs/hr of superheated steam at 620 psi and 905° F.

Scotch – this type of boiler is commonly referred to as a scotch marine boiler. In a scotch boiler, the furnace is a large diameter tube, within the boiler, surrounded by water. Some older, large scotch boilers had two or three furnaces but modern boilers typically have only one. Scotch boilers may be two-pass, three-pass, or four-pass depending upon the arrangement of baffles and tubes

Figure : Water tube boiler schematic A. WATER TUBE BOILER…Contd: As you can see, the Babcock Marine Water Tube Boiler in below is looks very complicated. Thousands of tubes are placed in strategic location to optimize the exchange of energy from the heat to the water in the tubes. These types of boilers are most common because of their ability to deliver large quantities of steam. Figure
Scotch Marine Boiler. Scotch marine boiler is a fire tube boiler. It is also a scotch or tank type boiler which is used for the marine works. The reason behind, it is used for marine work is its compactness, efficiency in operation and its ability to work in any type of water.

The water tube boiler consists of finned tube or bare tube bundles mounted together in sections. Needs proper water treatment and cleaning. The water/steam mixture is then separated in a steam drum or in an auxiliary boiler. or by a three-way exhaust gas damper.
Marine Boilers, Third Edition provides practical information about boilers and other relevant equipment used at sea on steam and motor vessels. The coverage of the book includes auxiliary boilers, water tube boilers, and boiler mountings. The text also covers stresses in boiler shells; combustion of fuel in boilers; and boiler operation. The book will be of great use to marine engineers
WATER TUBE BOILER: A water tube boiler is a type of boiler in which water circulates in tubes heated externally by the fire. additional generating tubes are separate in the furnace. In smaller boilers. creating hot gas which heats water in the steam-generating tubes. while larger utility boilers rely on the water-filled tubes that make up the walls of the furnace to generate steam. .

Marine Two Drum Water Tube Boilers. In a two drum boiler the bottom drum is known as the water drum, and the other drum positioned above it is the steam drum. Banks of water tubes connect both drums, along with larger down-comers if used circulating the hot water. The Superheater. Exiting the steam drum, the saturated steam is fed through a superheater, which is a nest of coils suspended …
Generally we use the water tube boiler in order to generate the super heated steam like on steam ships etc. the pressure generated on water tubes is always higher the smoke type of boilers. The best example of this type of boiler is the cooker that we use in our home.
In water wall tubes, water flows and takes away the heat surrounding it. Thus the heat inside the boiler does not get transmitted to the outside of the boiler. These are of three designs namely: water cooled with refractory covered studded tubes; Close pitched exposed tubes and membrane Wall.

Proper boiler water treatment eliminates sludge and scale deposits within the boiler. However, over along period of time a film of copper and iron oxides build up on the tube surface. Most of these oxides are transported from oxides of corrosion within the feed system to the boiler with the condensate.
