2. BOILERS - Bureau of Energy Efficiency operational. Package boilers are generally of shell type with fire tube design so as to achieve high heat transfer rates by both radiation and convection (Refer Figure 2.4). Figure 2.2 Fire Tube Boiler Figure 2.3 Water Tube
Two drum water tube boiler types - SlideSha Oct 09, 2015· 2. Two drum water tube boiler Two drum traveling grate boiler can be adjusted to many kinds of coal, which adopts water- cooling arch and membrane water-cooling wall, which is a new type water tube shop-assemble boiler, has the features of wide range of over load adjusting.
Water tube boilers are classified as follows: 1. Horizontal straight tube boilers (a) Longitudinal drum (b) Cross-drum. 2. Bent tube boilers (a) Two drum (b) Three drum (c) Low head three drum (d) four drum. 3. Cyclone fired boilers Various advantages of water tube
The water within the water drum, and the connecting pipes to the other two upper drums, are heated, and the steam bubbles produced rise into the upper drums where the steam is then taken off. The bent tube or Stirling boiler allows for a large surface heat transfer area, as well as promoting natural water …
Our elevated-drum design is used for drum retention times of 5 minutes or more from normal water level to low water fuel cutout. Additionally, this design is utilized where shipping limitations exist as it allows for a more symmetrical load with the upper steam drum shipped separately from the boiler …

3.Two types of high pressure water tube boilers are specified, flex tube and D-type. The two boiler types are significantly different, and only one of the two types should typically be specified if all new boilers in a given project are similar.
In water tube boilers, water and steam flow inside the tubes and the hot gases flow over the outside surface. Modern high-capacity boilers are of water tube type. The boiler circulation system is constructed of tubes, headers, and drums joined in an arrangement that provides water flow to generate steam.
Type of furnace generating steam. Schematic diagram of a marine-type watertube boiler. 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 boils water in the steam-generating tubes.
