It is a water tube, forced circulation boiler, where the feed water is compressed to supercritical pressure to prevent the formation of bubbles in the water tube. The compressed water feed increases the density of the water such that its density and that of the steam become the same, which reduces the latent heat in the water to zero making it easier to convert to steam.

Feed water pumps (FWP) pump the feed water from the de-aerator through the HP heaters to the boiler. The major characteristic of FWP is their high differential head. In medium to large size coal- and oil-fired power plants, the main FWP are horizontal barrel type while booster pumps are horizontal single stage double suction type.
Answer: A. clarification: The boiler is started from cold by circulating the feed water from the hot well by operating the starting valve. While taking the boiler on range, starting valve is closed and valve 2 is opened. This method avoids excessive heating of tubes.

2021/4/19 · Watertube boilers. The construction of watertube boilers, which use small-diameter tubes and have a small steam drum, enables the generation or production of steam at high temperatures and pressures. The weight of the boiler is much less than an equivalent firetube boiler and the steam raising. Figure 4.2 Foster Wheeler D-Type boiler.
Waste heat boiler—a device that uses waste heat from a process to produce steam, p. 297. Water tube boiler—a type of boiler that contains water-filled tubes that allow water to circulate through a heated firebox, p. 296. 14.1 Introduction Steam has many
The small and narrow application of the site can choose vertical boiler, spacious site can choose horizontal boiler. In comparison, it mainly depends on the needs of the customers, because the two kinds of boilers are different in scope of use, for example, if they want to heat 100 thousand square meters, then the vertical boiler is not enough.
2017/7/25 · We briefly discuss about Water tube boiler parts and functions. D type water tube boiler. In the water tube boiler, the water and steam flow inside the tubes and the hot gases flow over the outside surfaces. Where as in fire tube boilers hot gases from combustion travels through the tubes. flue gases produced from furnace where fuel is burnt.
