Boiler Tube Failure Analysis There are many different types of boiler tube failure mechanisms, which can be sorted into six general categories: - Stress rupture (short-term overheating, high temperature creep, dissimilar metal welds)
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
The Rentech D Type Watertube boiler is known for its proven reliability, which is due, in part, to the 100% membrane wall construction eliminating the need for refractory and assists in reducing emissions. Efficient heat transfers enables the Rentech D Type Watertube to achieve full steaming capacity more quickly than with designs used in other boilers.
Corrosion is a relevant problem caused by water in boilers. Corrosion can be of widely varying origin and nature due to the action of dissolved oxygen , to corrosion currents set up as a result of heterogeneities on metal surfaces, or to the iron being directly attacked by the water.

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 four major historical types of boilers: low
Types of High Pressure Boilers. A boiler is a vessel in which water is heated under pressure and vaporized into steam for a specific purpose. There are several different kinds of boilers, heated by coal, solid fuel, oil or gas. Boilers vary widely in size from small, portable or shop-assembled units to large furnaces
Boiler Types: Live steam models utilize many different varieties of boilers ranging from the simple pot to the locomotive type. Each boiler type can give excellent performance so long as it is operated within its design envelope. Copper is the best material for small boilers.

Oil & Gas Fired Smoke Tube Type Steam Boilers : We manufacture wide range of Oil and Gas Fired Steam Boilers. The oil and gas fired steam boilers manufactured by us are developed using the latest technology. These steam boilers have the coil type & Smoke tube type with three pass designs making them efficient and free from any hazard.
4 Most Common Types Of Steam Boilers. The first thing you should know about steam boilers is that no two boilers are created equal. From the outside, it may seem like all boilers are more or less the same. However, there are several different types of boilers with different qualities, different designs, and different purposes.

Fire Tube or Shell Boilers. This is the most common type of boiler used in small and medium sized industrial installations. Fire tube boilers are often produced as 'packaged' units complete with pumps and control system, requiring only connection to a suitable water and fuel supply before commencing operation.

WNS type boiler. WNS type boiler can burn oil or gas, which is cleaner than others. This boilers are mainly used in school, hospital, hotel, textile industry, chemical plant, power plant, paper & pulp, pharmaceuticals, refinery, food processing, building materials, etc. It include fire tube boiler, water tube boiler and popular D type water
Steam boiler efficiency depends upon the size of boiler used. A typical efficiency of steam boiler is 80% to 88%. Actually there are some losses occur like incomplete combustion, radiating loss occurs from steam boiler surrounding wall, defective combustion gas etc. Hence, efficiency of steam boiler gives this result.
Vertical - this type of boiler is a one-pass boiler with the furnace at the bottom and tubes running between the lower and upper tube sheets. The furnace can be enclosed on its sides with a water cooled jacket or it may be made up of masonry. The top tube sheet in a steam boiler can be above or below the water line.
THE BABCOCK & WILCOX BOILER. The following brief description of the Babcock & Wilcox boiler will clearly indicate the manner in which it fulfills the requirements of the perfect steam boiler already enumerated. The Babcock & Wilcox boiler is built in two general classes, the longitudinal drum type and the cross drum type.
Boiler Tubes are metal tubes located inside of boilers that heat water in order to produce steam. There are two major types of tube boilers: water-tube boilers and fire-tube boilers. In water-tube boilers, water circulates inside the tubes and is heated externally by hot gases generated by the furnace.
Heat Transfer In Steam Boiler. A steam boiler is designed to absorb the maximum amount of heat released from the process of combustion. There are three way (Radiation, convection & Conduction) that heat is transfer in the boiler and relative percentage of each heat transfer within system boiler is dependent on the type of steam boiler, fuels and the designed transfer surface.

Steam Boiler Types. The steam boilers are classified into several types based on its requirement. Water Tube Boiler. The water tube boiler is one type of boiler, and the main function of this boiler is the water in the tube will be heated to generate the vapor.
There are three main types of steam boilers: Fire tube, water tube, and cast iron. In fire tube boilers, the combustion gases travel within the tubes to heat the surrounding water. Fire Tube Boiler Water Tube Boiler In water tube boilers the water travels inside the tubes and the heat on the outside, as shown in the video above.

Fire-tube boilers are used in order to add hot gases from the heating source through tubes attached inside a water-filled drum so that heat could be transformed into the water. Horizontal return tubular (HRT) boilers are generally held horizontal shape having self-contained fire-tubes along with a separate combustion chamber.
These boilers can also be supplied with a circulating pump to comply with the coil type design and provide the same operator exclusion while offering higher efficiency and steam quality than a coil type boiler. When firetube boilers are not the favoured type of boiler due to the stationery engineer's regulation constraints, a flexible
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

SZS Series Water Tube Gas Oil Fired Steam Boiler. SZS series double drum steam boiler is a packaged water tube boiler with D-type layout. Suitable for large capacity
Flexible water tube boilers typically consist of an upper and lower water drum with a series of bent steel tubes designed to absorb the stresses of thermal expansion (see Figure 2). The overall efficiency of this application can be relatively low when compared to other types of boilers and piping configurations.
How Water Tube Type Steam Boilers Work. One of the latest advances in steam boiler technology is the use of water tube boilers.This type of boiler is distinct from conventional fire tube boilers. Water tube boilers are more efficient than fire tube boilers, generating more steam but using less fuel. They are also much safer than fire tube boilers and easier to manage when it comes to routine
