What are the differences between a vertical and horizontal type boiler?
While vertical boilers stand upright and erect, horizontal boilers are elongated. Within the choices of horizontal boilers, two of the most popular are horizontal fire tube boilers and horizontal water tube boilers.
What is horizontal boiler in mechanical engineering?
It consists of a horizontal drum which holds water and steam. In this boiler, the circulation of water takes place by natural means due to difference in density.
What is accessories of boiler?
Boiler accessories are devices and plants that are installed with boilers to improve the operating condition and overall efficiency of the boiler plant. Boiler accessories are devices that are installed along the boiler and the surrounding area to increase the efficiency of the boiler.

Which type of boiler is most efficient?
Condensing boilers
What is the most efficient type of boiler? Condensing boilers are the most energy efficient, typically being 25% more efficient than non-condensing models.
What is Draught in boiler?
Boiler draught is defined as the difference between absolute gas pressure at any point in a flow passage and the ambient (same elevation) atmospheric pressure. Draught is achieved a small pressure difference which causes the flow of air or gas to take place. It is measured in millimetre (mm) or water.
What is Babcock and Wilcox boiler?
Babcock And Wilcox Boiler is a stationary water tube boiler. It consists of the steam-water drum. a short tube connects the steam water drum with the uptake header and down header as shown in the figure.
What are the features of a horizontal boiler?
Horizontal boiler features: large water capacity, high thermal efficiency, enough steam and long service life. Equipped with high quality brand burner and booster feed pump, it has enough combustion, timely water supply and low noise.
What kind of boiler is the Cochran boiler?
The Cochran boiler is also a vertical-type boiler of multi-tubular design. It includes multiple horizontal fire tubes. This style of boiler incorporates a horizontal single-pass design. Flames are pushed into corresponding small-diameter tubes. The multiple small-diameter tubes are individually immersed in water.
Which is the oldest type of industrial boiler?
As one of the oldest and most simple designs for industrial boilers, the Horizontal Return Tubular fire tube boilers are still being produced today. It features a shell, a tube sheet on each end of the shell, and tubes that connect both tube sheets. The boiler is mounted above the masonry or steel furnace.
What was the original design of a locomotive boiler?
The locomotive boiler is an obsolete design. Originally found in steam locomotives, wood or coal was burned in the combustion chamber (furnace). A unit with a horizontal tube design, it was a rugged piece of equipment, with a high steam capacity.
