Water Tube Boilers In this type of boiler water passes through the tubes while the gases remain in the shell side, passing over the tube surfaces Used for high steam demand and pressure requirements Capacity range of 4,000 120,000 kg/hour.
Water drum size is limited to that required to receive the generating tubes, for modern radiant heat boilers with only a single bank of screen tubes and no generating tubes between the drums, the water drum has been replaced by a header and the downcomers fed straight to the waterwall headers.
18.104.22.168 Water-Tube Boilers . Most high-pressure and large boilers are of this type (Figure 9.2.2). It is important to note that the small tubes in the water-tube boiler can withstand high pressure better than the large vessels of a ire-tube boiler. In the water-tube boiler, gases low over water-illed tubes. These water-illed tubes
Fire-tube boilers are generally similar to Scotch marine or locomotive boilers. In this type of boiler, the gases of combustion pass through tubes that are surrounded by water. There are a number of auxiliary boilers of the fire-tube type in use in diesel-driven ships. Figure 18-12 illustrates a cutaway view of the fire-tube boiler shown in
The first successful user of water-tube boilers, however, was James Rumsey, an American inventor, celebrated for his early experiments in steam navigation, and it is he who may be truly classed as the originator of the water-tube boiler. In 1788 he patented, in England, several forms of boilers, some of which were of the water-tube type.
Fire Tube boiler is the simplest form of the internal furnace, vertical fire tube boiler.Fire tube boilers are a portable boiler and it requires a small floor space. The steam rating in fire tube boilers doesn't exceed 2500 kg per hour and pressure is limited to 10 bars.
Water Tube Boiler is a high-pressure boiler that operates at a pressure of about 165 bar. Basically, in this boiler, water will be flown inside the tubes surrounded by flue gases. More steam is generated by using this boiler so, the overall efficiency of the boiler is high.

Introduction. This article deals with the famous ESD III type water tube marine boilers available in the market today. ESD III type boilers substituted ESD II type for the same reason for which ESD II substituted ESD I, i.e. to accommodate a higher superheated steam temperature range. Moreover, the ESD II type are more technically advanced and have better efficiency.
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
Water Tube Damage: Boiler Tube can be damaged if there is any dust in the feed water. Because it blocks the water circulation. The deposition of salt and sediments in the inner surface of the Water Tube is a common problem for this type of boiler. Water Level: Water Tube Boiler uses less water and for this reason, the water level needs to check

The number and size of the tubes, the type of fuel, and the overall physical dimensions of the boiler will all vary depending on what the boiler is designed to produce (water, steam, or heat) and the industry it is intended to serve (e.g., utility, industrial, medical).
Water-tube boilers differ from shell type boilers in that the water is circulated inside the tubes, with the heat source surrounding them. Referring back to the equation for hoop stress (Equation 3.2.1), it is easy to see that because the tube diameter is significantly smaller, much higher pressures can be tolerated for the same stress.
In fire-tube boilers, flue gases are inside of tubes, and water is in the shell around the tubes. Steam Applications. In steam applications, water quality is an important part of boiler selection. Steam boilers tend to be steel water-tube- or fire-tube-type boilers in the 10-to-1,000-hp range. Fire-tube boilers are more robust and more tolerant
BOILER BASICS AND TYPES OF BOILERS - WATER TUBE BOILER AND FIRE TUBE BOILER In other cases, special forced circulation boilers have been designed, which consist of many rows of tubes without a steam drum. In another type, heat is supplied by steam from a standard type of boiler which heats the water in a direct contact heater.
