A steam boiler is a power generation device, used for generating steam by applying the heat energy to water.The pressure range of earlier boilers ranges from low pressure to medium pressure (7 kPa to 2000 kPa/ 1psi to 290 psi).The present boilers are more useful because it works with high pressure than old ones.

Jan 24, 2019 · The water tube boiler diagram is shown below, and these two drums are associated via two tubes such as downcomer and riser. At first, the water is supplied into the steam type drum with the help of a water pump. Whenever the fuel is burned, then hot gases will be generated that are permitted to supply in the shell part of the boiler.

Aug 28, 2019 · 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. The water Tube boiler is shown in the figure below.

Read MoreScotch Marine boiler Diagram : Scotch marine boiler diagram. The combustion chamber walls form the best heating surface. The furnace tubes, smoke tubes, and the combustion chamber, all being surrounded by water, give a very large heating surface area in proportion to the cubical size of the boiler. The water circulates around the smoke tubes.

Apr 17, 2015 · Fire Tube Boilers 8. 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 • Combustion efficiency enhanced by induced draft fans.

Water-tube boilers also have a downcomer tube that connects the steam drum to the feedwater drum. If the steam cools and condenses back into water droplets, that water can drain from the steam drum to the feedwater drum via the downcomer tube. This allows that water to re-enter the boiler's water supply, go back into the tubes, and once again

A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or 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-pressure tank
