The available heat for the boiler at 500°F and theoretical combustion equals 9, 150,000 BTU per hour. If 20 percent excess combustion air was used, the available heat at 500°F would be decreased to about 79 percent of the gross heating value for natural gas (calculated from Figure 4).Get Price
A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.Get Price
123. Why large boilers are water tube type ? Water tube boilers raise steam fast because of large heat transfer area and positive water circulation. Thus they respond faster to fluctuations in demand. Further single tube failure does not lead to catastrophy. 124. What type of boiler does not need a steam drum ? Super-critical pressure boiler. 125.Get Price
Magnetic particle examination (MT) is a very popular, low-cost method to perform nondestructive examination (NDE) of ferromagnetic material. Ferromagnetic is defined in ASME Section V as "a term applied to materials that can be magnetized or strongly attracted by a magnetic field."Get Price
Sep 01, 2014 · The idea is to find the tube in the boiler with the most deposit in a high-heat area. You cannot use a tube that has failed, because some or all …Get Price

The Babcock and Wilcox boiler is a water tube horizontal boiler with natural draft circulation and multiple tubing. Water enters the tubes by a down take header, is heated by hot flue gases and moves in a zigzag fashion forced by baffle plates. The steam in the tubes moves to an uptake header, where it is collected in a boiler drum.Get Price
