In a water tube boiler comprising rows of inclined water tubes, a superheater above the tubes, a pier resting on the top tubes of the rows, tension means embracing, the lat ter tubes to hold the pier in place on the tubes and having projections extending downwardly from the tubes, and reversible heat resisting blocks located back to back in a

Two-dimensional (2-D) finite element models were developed and axi-symmetric triangular elements for the tube cross section area were employed. The results showed that the temperature distribution at the tube wall decreases with increased mass flow rate of steam and increased scale

A separately fired superheater is a superheater that is placed outside the main boiler, which has its own separate combustion system.

Alternative water-tube boiler layouts. The following layouts work on the same principles as other water-tube boilers, and are available with capacities from 5 000 kg/h to 180 000 kg/h. Longitudinal drum boiler. The longitudinal drum boiler was the original type of water-tube boiler that operated on the thermo-siphon principle (see Figure 3.3.5).

2019-10-2 · A slightly more successful adoption was the use of hybrid water-tube / fire-tube systems. As the hottest part of a locomotive boiler is the firebox, it was an effective design to use a water-tube design here and a conventional fire-tube boiler as an economiser (i.e. pre-heater) in the usual position.

We use water-tube boilers in cases where conventional smoke-tube boiler plants are not capable of providing the required parameters. Water-tube boilers are compatible with a wide range of different configurations and combustion chamber designs. If needed, heating surfaces can be cleaned during boiler …

2019-10-2 · A high pressure watertube boiler[1] (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace
