Backpressure: Pressure, higher than the supply pressure, caused by a pump, elevated tank, boiler, or other means that can cause backflow. Backsiphonage: Backflow caused by negative or reduced pressure in the supply piping. Cross-connection: A connection or potential connection between any part of the potable water system and another environmentGet Price

From Example 8.2, the existing boiler has an excess O 2 of 6% and an overall boiler thermal efficiency of about 78% (i.e., η s t d = 0.78). After the boiler tune-up, the excess O 2 is 3%. Using the monograph of Fig. 8.12, the new boiler efficiency can be determined from the flue gas temperature (343°C or 650°F) and the excess O 2 (3%).Get Price
Oct 16, 2013 · The ratio of exit pipe cross-sectional area to total tube cross-sectional area should not be less than 0.75 unless there is a very special reason and careful design. The recommended value is 1.0. Long radius elbows and 90° tee type exits of the same minimum cross-section were found by HTRI to give similar overall reboiler performance.Get Price

A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.. The fire-tube boiler developed as the third of the four major historical types of boilers: low …Get Price
