'Wet preservation', using ammonia & hydrazine solutions and possibly nitrogen filling, can be used for preservation over quite extended periods. However, the first choice for the preservation & Maintenance of boiler, turbines, condensers and feed systems shall be 'dry preservation' with dry air circulation.
The short-term is a wet layup and consists of leaving the boiler filled with concentrated, chemically treated boiler water; preferably with a pH of 12.4 (or as close as possible). Semi-Short Term Boiler Layup Procedure — If you plan to shut down your boiler from 10 - 30 days, then you should perform the semi-short term layup.
A water tube boiler is such kind of boiler where the water is heated inside tubes and the hot gasses surround them. This is the basic definition of water tube boiler. Actually this boiler is just opposite of fire tube boiler where hot gasses are passed through tubes which are surrounded by water.. Advantages of Water Tube Boiler. There are many advantages of water tube boiler due to which

The boiler is the heart of the steam system. The typical modern packaged boiler is powered by a burner which sends heat into the boiler tubes. The hot gases from the burner pass backwards and forwards up to 3 times through a series of tubes to gain the maximum transfer of heat through the tube surfaces to the surrounding boiler water.
DISCUSSION OF BOILER ROOM CLASSIFICATION Richard L. Dornfeld, P.E. Walker Process Equipment Division of McNish Corporation July 26, 2011 All fired boilers including Anaerobic Digestion Boilers cannot be placed in spaces designated as hazardous locations due to the spark or flame ignition and standing flame during operation.

Water tube boilers are the most widely used boilers. These type has replaced many boilers, including the fire tube type, mainly because of the following reasons : The weight of the water tube boiler is much less than any type of boiler of equivalent size. Steam raising and steam generation process is much faster
Drying refractory is critical for strong, long-lasting refractory applications. Unfortunately, standard refractory dry-out schedules, provided by all refractory manufacturers with their products, are difficult to apply to refractory used on a steam-generating boiler. These standard dry-out schedules are generic and require temperature monitoring rarely found at power plants, where monitoring

Internal furnace boiler - Fire tube Boiler - Packaging Boiler - This is the conventional three pass smoke-tube design coal/wood fired steam boiler having internal furnace. This comes in dry back, semi-wet back and fully wet-back options and is most suitable for manual firing of coal, wood or briquettes.
Two primary boiler types, the firetube boiler and the watertube boiler, are essentially opposite in design. The firetube boiler passes combustion gas inside a series of tubes surrounded by water in a vessel to produce steam, while a watertube instead sends water through a series of tubes surrounded by combustion gas used to transfer heat energy
Wet Back Firetube Boilers Suppliers. Wet back fire tube boiler design has a water cooled turn around chamber, which is used to direct the flue gases from the furnace to the tube banks. It requires less refractory maintenance. However, internal pressure maintenance, such as, cleaning is more difficult.
Oil Cum gas Fired Boilers (Except Small size in Oil fired ) are three pass wet pack, horizontal, smoke tube type fusion welded. Boiler are made to IBR / DIN / BS / ASME code.Components are Engineered for maximum safety, Highest Efficiency, dependability and quite operation.
Two other classifications of fire tube boilers are wet-back or dryback. This refers to the compartment at the end of the combustion chamber. This compartment is used as an insulating plenum so that the heat from the combustion chamber, which can be several thousand degrees, does not reach the boiler's steel jacket.
A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes
The weakest part of a conventional fire tube boiler is found in the combustion gas turnaround chamber, located just after the boiler furnace and comprised of the refractory frame and the back lid, the latter of which is made of refractory and insulating materials. This type of turnaround chamber is called a "Wet-Back" in contrast to the
Fire-tube boilers - with straight tubes, stay-bolts and fixed tube-sheets - are exceptionally rigid, with no provision for the tubes or stay bolts to freely expand and contract. If a fire-tube boiler heats up evenly to a uniform temperature and remains that way (idling when there was no steam demand), no biggie.
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 design of the wet back boiler can be frustrating for Boilermakers due to the limited access to install tubes in the combustion return area of the boiler. The limited space in wet back boilers makes it necessary to choose alternative methods of tube installation.
Oxygen can quickly produce pitting in steel tube sheets and boiler tubes. Once oxygen pitting starts, it can easily corrode through a boiler tube in a very short period of time. When it is time to start your boiler back up in the fall, you could first have to make a call to a mechanical contractor to plug or replace the corroded tubes.
