In these cases, multiply the boiler pressure by 1.15 to calculate the blowdown rate from Figure 3.14.1. Blowdown lines over 7.5 m can be read straight from this graph. Example 3.14.1: For a boiler pressure of 10 bar g, an equivalent 40 mm blowdown line length is calculated to be 10 m, consequently, the blowdown rate is 6.2 kg/s (see Figure 3.14.1).Get Price
Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressureGet Price

- Direct steam-type humidifiers inject boiler-generated steam directly into the air stream. These systems normally operate above 70 degrees C (158 degrees F), and Legionella cannot survive at that temperature. - Atomizing humidifiers use mechanical devices or pneumatic air to create a water mist that evaporates into the air stream.Get Price
Install soot-blowers to remove boiler tube deposits that reduce heat transfer between the hot combustion gas and the water. The improvement in the boiler efficiency depends on the flue gas temperature. • Use economizers to transfer energy from stack flue gases to incoming feedwater.Get Price
In fire tube boiler the hot products of combustion pass through the tubes, which are surrounded, by water. Fire tube boilers have low initial cost, and are more compacts. But they are more likely to explosion, water volume is large and due to poor circulation they cannot meet quickly the change in steam demand.Get Price

Dec 01, 2016 · Hot water from a gas-fired standard cast-iron boiler (Figures 50, 51) was forced through the pipes by a circulation pump. The boiler was fired with LP gas for start-up and switched to biogas when production permitted. Thereafter, the boiler was operated on biogas entirely, except for its pilot light, which used LP gas continuously.Get Price

A reasonably well-insulated shell or water-tube boiler of 5 MW or more will lose between 0.3 and 0.5% of its energy to the surroundings. This may not appear to be a large amount, but it must be remembered that this is 0.3 to 0.5% of the boiler's full-load rating, and this loss will remain constant, even if the boiler is not exporting steam to Get Price
