D Drum. Drum or generally called shell contains water, steam or mixture of both water and steam. In smoke tube boilers shell contains a mixture of both water and steam, water being denser forms the lower part of the shell while steam is above water level. In water tube boilers, water and steam can be filled in the same drum or separate drums.
In response to this need, the package or shop-assembled boilers were developed. A package boiler is a pre-engineered steam-generating boiler that ranges in size and steam capacity (typically from 10,000 to 600,000 lb/hr) built in a shop and shipped by rail or barge. Many companies manufactured these small shop-assembled boilers.
It is possible for a 3-pass boiler with a tube design (such as XID boiler tubes) that allows more heat transfer time to deliver the same or higher efficiency rating than a 4-pass boiler with standard tubes. 3 pass firetube boilers offer: maximized heat transfer; minimal refractory; high steam/water storage; effective handling of wide load demands
Delivering Boilers with world-leading quality and performance. Boilers are key components of thermal power plants. They convert the chemical energy contained in fossil fuels such as coal, oil and gas into thermal energy through combustion reactions and use the resultant high-temperature and high-pressure steam-based thermal energy for supplying steam turbines used in power generation.

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
Steam generators. In many applications: The amount of steam required is too small to warrant a shell boiler, i.e. Less than 1 000 kg / h. The small process requiring steam operates on a day shift only, meaning that the plant would be started every morning and shut down every night.
The RS series of steam boilers manufactured by us are 3 pass conventional wet back design shell type steam boilers. These are manufactured as per stringent Indian Boiler Regulations (IBR).

heat to the water in the boiler. A 4-pass design provides four opportunities for heat transfer. The stack temperature of a 4-pass boiler will be lower than the stack temperature of a 2 or 3-pass boiler, of the same basic design, operating under similar conditions. Because of this fact, the 4-pass will have higher efficiency and lower fuel cost.

Standard pressure up to 12 bar (higher pressure available on request) and output from 300 to 6000 kg/h. The boiler is high efficiency and copes well with instantaneous demand due to its horizontal design
The water stored in the steam boilers allows for a much better response to changing steam demand from the plant than the single through design of a steam generator. It is also worth noting that steam boilers are more adaptable to the needs of a business. Depending on the construction of your building or its energy usage, steam boilers can be
Steam output: 300 – 16,000 kg/h BBS single flame tube three-pass boilers are produced as saturated steam and optionally as hot steam generators. Operating pressures of up to 30 bar depending on capacity. BBS three-pass steam boilers are exceptional due to their high levels of efficiency, safety, robust design and minimal operating requirements.
The package boiler is usually a two or three-pass fire-tube boiler with an internal furnace tube. This is similar to the much earlier Scotch boiler . Generating tubes filled with water are in direct contact with the heat source inside the boiler, causing damage to the pipes as well as scaling.
three-pass boiler The technical progress during the last 70 years has led to the development of a boiler type, which is world wide known as the 'Three-Pass Boiler'.

Oct 28, 2014 · Steam Boilers OR Steam Generators 1. Boilers (Steam Generators) 2. Definition of a boiler • A boiler is a device used to generate steam at a desired pressure and temperature by transferring heat energy produced by burning fuel to water to change it to steam. • It is a combination of apparatus used for producing, furnishing or rec
The Steam Superheater is a coil type heat exchanger which is used to produce superheated steam or to convert the wet steam to dry steam, generated by a boiler. It is different from a boiler in a way that, boiler utilizes both sensible heat as well as latent heat to convert water into steam while superheater utilizes only sensible heat to
Once-through boilers are able to produce steam at higher pressures and temperatures than drum boilers. In thermal power plants, raising steam conditions (pressure and temperature) can enable efficiency gains in power generation equipment, allowing an operator to reduce its fuel consumption and CO 2 emissions.
Steam Production From steam tables we can see that the total heat of steam does not vary a great deal as the boiler pressure increase The boiling point (b.p.) increases as the pressure increases Thus the sensible heat increases as the pressure increases, and the latent heat decreases Boiler pressures are expressed in psia, psig, bar, kg/cm2
