| 1) The burner and electrical control panel are protected by a weatherproof housing for on deck usage. Control panel meets USCG. |
|
| 2) High combustion efficiency is obtained by pressure atomization of fuel oil and high pressure air. An electric pre-heater heats the residual fuel oils for proper atomization. |
|
| 3) Electrical panel meets all required codes and can be mounted on either side of the heater package. |
|
| 4) Optional controls provide full modulation with low fire start and up to 10:1 turn down ratio. Burners meet USCG requirements and ABS on request. |
|
| 5) Extra heavy steel cylindrical shell surrounds the helical single or double wound coil made from Schedule 40/80 seamless pipe. Spacers separate the coil and shell. |
|
| 6) The shell is covered with layers of ceramic fiber blanket insulation. A rigidizer is sprayed on the surface to protect against velocity of exiting gases. |
| 7) Helical Coil - Single or double wound, designed by Volcanic. |
| 8) Access door allows for inspection and maintenance tasks. |
|
| 10) Separation/Surge Tank - Velocity of thermal liquid return from system is decreased to allow any steam or air in the system to escape into the expansion tank. |
|
| 11) Expansion Tank - As the system is brought up to operating temperature, heated thermal liquid expands into the expansion tank from the separation tank. Thermal liquids expands approximately 4% by volume per 100°F temperature increase. When the system is shut down and the liquid cools, liquid is withdrawn from the expansion tank to maintain a filled circulating loop. |
|
| 12) Cold Seal Tank - The thermal liquid system is vented to the atmosphere through this tank to expel air and any steam during system start-up. |
|
| 13) Circulating Pump - A centrifugal pump is used to supply thermal liquid for the entire system. Pumps are selected to meet flow and pressure drop requirements of the system. Pumps are jacketed for water cooling when required. |
