A boiler drum vent typically opens at 2 kg/cm² (approximately 2 bar) to relieve excess pressure and prevent over-pressurization, which can lead to equipment failure or hazardous situations. This pressure setting is determined based on the design and operational safety margins of the boiler system. By venting at this pressure, the system can maintain safe operating conditions while allowing for the necessary steam generation and distribution. This safety feature is essential for protecting both the boiler and associated equipment.
140 kg/cm2
Boiler feed pump's suction pressure be aprox. 15Kg/cm2 and discharge pressure be 180Kg/cm2. So the balancing line balance the pressure and protect the boiler feed pump. my quastion is that what is the working principal of balancing leak off
Formula: kg/cm2 x 9.807 = newtons/cm2
1 * 11 = 11 cm2 2 * 10 = 20 cm2 3 * 9 = 27 cm2 4 * 8 = 32 cm2 5 * 7 = 35 cm2 6 * 6 = 36 cm2 7 * 5 = 35 cm2 8 * 4 = 32 cm2 9 * 3 = 27 cm2 10 * 2 = 20 cm2 11 * 1 = 11 cm2
27.53 cm2 approx.27.53 cm2 approx.27.53 cm2 approx.27.53 cm2 approx.
Sorry the options are actually 64 cm2, 16 cm2, 32 cm2, 50 cm2. Thanks
10000 cm2 in one m2
You times the m2 by 10,000 to get cm2. and You divide cm2 by 10,000 to get m2
32 cm2
cm2
Just divide the numbers, and the answer will have no measurement units.
1.87 m2 = 18700 cm2
