Road Fuel & Off-Road Fuel:
 
|
By separating the fuel tanks for road use and off-road use, substantial fuel road taxes can be avoided. The off-road fuel tank of the Ultraliner Boiler Truck has a 100 gallon capacity and is used for the boiler, the generator, and the air compressor.
Note: Diesel powered equipment simplifies fuel supply issues. Some alternative fuel sources, such as propane, can have performance problems under cold weather conditions. Many field crews seem to have difficulty ensuring adequate availability of alternative fuels. |

Boiler Air Compressor:
|
The boiler air compressor is used to atomize the fuel. Atomization results in a cleaner burning boiler with greater fuel efficiency. |
Boiler Fire Controls:
|
The fire controls are used to adjust the flame height to low or high, depending upon the desired boiler temperature. When the pipeliner is being pre-heated in the reel trailer, the super-heated steam drops to 212 degrees F within the unpressurized trailer, regardless of the boiler temperature. Thus while pre-heating the pipeliner in the reel trailer, a higher boiler temperature will release more thermal energy faster without altering the temperature to which the pipeliner is actually exposed.
During pipeliner processing, the boiler temperature is generally lowered by adjusting the flame height. [Note: The addition of compressed air helps to further lower the temperature to the desired range, even when pressurizing the pipeliner. The addition of air also results in a "drier" steam. However, the temperature and volume of the actual steam introduced into the pipeliner will determine the thermal energy available to heat the pipeliner and will greatly affect the required processing time.] |
Boiler Fuel Pressure Gauge
& Flame Window:
|
Fuel pressure gauges are placed throughout the fuel system to assist in maintenance and troubleshooting. The flame window allows visual confirmation of the boiler operation. |
