Firetube Boilers - The National Board of Boiler and

In a scotch boiler, the furnace is a large diameter tube, within the boiler, surrounded by water. Some older, large scotch boilers had two or three furnaces but modern boilers typically have only one. Scotch boilers may be two-pass, three-pass, or four-pass depending upon the arrangement of baffles and tubes.

Superheated steam - Wikipedia

Superheated steam was widely used in main line steam locomotives. Saturated steam has three main disadvantages in a steam engine: it contains small droplets of water which have to be periodically drained from the cylinders; being precisely at the boiling point of water for the boiler pressure in use, it inevitably condenses to some extent in the steam pipes and cylinders outside the boiler

Choosing the best boiler for your buck

Sep 09, 2015 · Firetube boiler capacities can be as low as 50 hp or as high as 2,500 hp. These boilers contain large amounts of water and can react to load changes with little variation in operating pressure. The large water mass also means it takes more time to initiate steaming and to react to changes in …

Boiler Basics – Technology Transfer Services

Water-tube boilers may vary in design; however, their basic principles of operation are the same. This type of boiler consists of two drums, a series of water tubes, a feedwater inlet line, and a combustion gas outlet stack. These tubes are connected to a steam drum and a mud drum. The water is heated and steam is produced in the upper drum.

stack gas temperature are reduced in firetube boilers that are equipped with heat recovery equipment, such as feedwater economizers, condensing economizers, or air preheaters. Perform Visual Inspections Visually inspect boiler tubes when the unit is shut down for maintenance. Scale removal can be achieved by mechanical means or acid cleaning.

Fire Tube Steam Boilers - Babcock Wanson

These tubes are surrounded by a water jacket. The heat from the hot gases transfers through the walls of the tubes and heats the water. In a water-tube boiler, the water is in the tubes while the fire is external to the tubes. The hot flue gases pass around and between the tubes, heating the water and then out the boiler …
