2019-3-28 · I understand that by conservation of mass, it implies that 1 kg of water will give rise to 1 kg of steam. But when I consider the fact that there is phase change which is an abrupt and discontinuous change in the density of the fluid and it seems to me somewhat plausible to even consider this question.
2019-5-26 · Fire tube or "fire in tube" boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to steam circulates. (Refer Figure 2.2). Fire tube boilers, typically have a lower initial cost, are more fuel efficient and easier to operate, but they are limited generally to capacities of 25 tons/hr and pressures of 17.5 kg/cm 2.
24.8.1 A boiler evaporates 3.6 kg of water per kg of coal burnt into dry saturated steam at 10 bar pressure .The temperature of feed water is 32 o C. Find the equivalent evaporation from and at 100 o C as well as factor of evaporation. Solution. Mass of steam produced, m s = 3.6 kg/kg of coal. Initial temperature of feed water, t w = 32 C

2011-4-5 · Water Treatment for High Pressure Boilers in Sugar Plants low for example at less than 0.4 ppm at a drum operating pressure of 80 kg/m2(g). Feed water is used as desuperheating spray and any contamination or feed water directly enters an optimum pH of 8.8 to 9.2 is recommended for feed water. Boiler water pH is
The composition of boiler feed water must be such that the impurities in it can be concentrated a reasonable number of times inside the boiler, without exceeding the tolerance limits of the particular boiler design. If the feed water does not meet these requirements it must be pretreated to remove impurities.
2017-6-3 · It is assumed that boiler feedwater preheat from ambient to condensate temperature (usually about 200°F) will be done by heat exchange against a process stream, outside the boiler island battery limits, with only some “top-up” heat recovery against hot boiler blowdown. The use of steam to preheat boiler feedwater was common when energy
