Combustion Systems
In the early 1980s, a company named Seaburn
asked us to design and price a liquid waste incineration system that
could be built within a standard 40 ft container to destroy waste
liquids from industrial plants. These units could be mounted on ships
or barges anchored at sea and stacked so several systems may be
operated from one central control station.
Waste liquids can be tested at the source to determine content and then
pumped into liquid waste containers for transfer to a ship or barge
containing the burner system at any convenient port within a few days.
The ship is designed with a control station, piping, pumps, filters,
liquid heaters, etc, to connect the burners with the liquid waste
containers. Waste burning continues until the containers are empty when
they are returned to port for unloading and any additional reloading.
If a burner system needs service, it can be quickly replaced while in
port and the damaged unit sent for repair.
The only other similar technology available in the 1980s was the
Vulcanus 1 and 2, however they proved a failure as the waste onboard
liquid tanks corroded and the refractory deteriorated due to weather
exposure. Additionally, when a Vulcanus unit was damaged, it took a
year for repairs to be completed to allow a second burn. Shortly
thereafter, legislation was passed and liquid waste burning at see was
prohibited. The decision to prohibit burning at sea was not a result of
any technical issues, but was determined strictly by politics.
The present BP oil spill in the Gulf of Mexico is of immediate major
concern with the cleanup being accomplished basically in three steps.
First, removal of the oil from the ocean and shoreline and second
processing, filtering and separation of the collected oil and water.
The third step is disposal of the oil to prevent further impact on the
environment.
Several companies are capable of providing the equipment to collect and
process the oil-water mixture with the separation technology offered by
Kevin Costner being one of the available options. That leaves only the
destruction of the oil collected and the most efficient way is to burn
it. Various systems are now being tested so a decision can be made on
what would be the best method.
The most recent efforts involving the burning of waste oil the is to
place 20 ft shipping containers containing small incineration systems
with separators and filters onto shrimp boats. These boats would travel
around the Gulf picking up oil, processing and then burning the oil
collected with compenstion being on a per barrel basis. Unfortunately,
these burning units are too small to have an immediate impact and will
require a great deal of fuel to operate. They will also require an
onboard, qualified engineer to operate the filtration and oil water
separation systems necessary to make each boat operate efficiently and
safely. While control of the collection, processing, and burning cannot
be monitored, flow-meters and recorders can be modified to record data.
Since each boat is compensated according to the quantity of oil they
collect and burn, shortcuts may be taken further compromising the
environment and the safety of the boat crews.
A more practical approach is to use the shrimp boats to collect the oil
in tanks taking care to collect a minimal amount of water. When the on
board tanks are full, the oil can be pumped to a larger transfer vessel
or taken directly to a barge where it can be processed and burned. The
oil collected at the barge can be tested for water content and the
vessel paid for quantity of oil collected with the amount adjusted to
account for water concentration. The less water content, the more the
vessel is paid per barrel. The burner systems would be placed on barges
and the barges located at various locations around the spill area.
Since the collection ships can load and unload quickly, they could be
deployed in priority areas such as along the coastline where the worst
pollution damage potential exists.

barge. The units can be set side by side with a stack bolted to the top
and are also available with an optional stack connection at the end,
which allows the units to fire and discharge horizontally. Systems may
be stacked vertically when operated in this manner. Should a system
require repair that cannot be performed at sea, the unit may be quickly
removed and replaced when the ship returns to port.
A multi-system setup with 5 systems across, stacked 3 systems high
could burn as much as 260 barrels per hour. The ship can be anchored
with the bow into the wind allowing the horizontal discharge to be off
the stern. All PLC controls for each unit can be monitored from a
central control station on board.
Storage,
Processing
and
Feed Systems
Support
components including pump/receiving stations are located near
the bow enabling the pump station to accept oil from the collection
fleet, which can offload to a barge. The oil would then be processed
with oil/water separators, including chemical treatment if necessary,
heated to 50°C and filtered. Processed oil is then moved to a
storage/supply tank supplying a recirculation distribution line
connected to each of the systems.
Once processed oil
is
available, the systems can be brought online with
#2 fuel oil, or a higher grade of the crude being processed. When the
system reaches operating temperature, the fuel oil is changed over to
the processed waste oil. Air vents from each of the process stations
can be vented to the combustion inlets of the systems further
reducing emissions.
Systems can be mass produced using the modular design described above.
Final assembly includes mounting in 20 or 40 ft. sea carrier trailers,
control panel with main power connections and remote interface controls
allowing the systems to operate independently from a main control
station or pilot house on board the ship. Systems are built to meet
Coast Guard Compliance and Certification. Other fabrication
sources may be used as delivery requirements dictate.

System Technical Details
Typical System Description
- 60FM-CGOL
Marine Waste Oil Combustion System is designed to raise the temperature
of the firing chamber to the required operating temperature, thus
assuring maximum destruction of any organics in the exhaust gas. The
system package comes complete with oil burner, refractory lined
chamber, stack, operating controls and when needed, the optional
components described below.
Refractory Lined Carbon
Steel Chamber
The package is constructed of carbon steel and lined with a combination
of ceramic fiber, high temperature refractory materials, which is
installed with stainless steel anchors to maintain integrity and
mounted on structural steel legs. Chamber includes sight ports, thermal
wells and a natural gas burner.
Oil
Burner (CGOL Option)
The system may include one (1) packaged oil fired burner for
maintaining the temperature of the chamber to the preset operating
temperature as required. System comes complete with flame safety
controls and safeties. A motorized, modulating gas valve regulates the
burner output using the latest Honeywell digital controllers. Burner
train components are supplied loose for field installation. Customer
supplies the natural gas regulator.

Operational Design
Controls (PLC Optional)
System operator may start and stop the system from the main panel or
from remote inputs. Startup energizes and prove the combustion blower,
start prepurge timer, fuel pumps, start burner on #2 oil, prove set
temperature and signal start of waste oil injection. Blower pressure
and customer safety limits must be proven prior to burner ignition.
Component failures will shut down the system while alerting the
operator. Indicator panel lights will display fault.
The system is designed to operate with a variable waste gas input with
natural gas being controlled to maintain a preset temperature. System
self-regulates fuel input to maintain temperature and adjust conditions
to match the flow of the waste gas stream.
Control Operation
The system can mix a portion of #2 fuel oil to maintain flame
stability. The #2 oil and waste oil will be connected to the suction
side of the fuel pump with motorized isolation valves. The system will
startup and run on #2 oil until the preset "At Temp" is reached.
When the correct temperature is reached, the waste oil valve will open
while the #2 oil valve
will begin to close. This process is completed slowly to allow the
system to monitor the flame with the UV Scanner. The scanner will
produce a flame strength signal that will assure an optimal flame
pattern. If a ratio is reached which lessens the flame strength, the
waste oil valve will not open further. The fuel mixture is fed to the
suction
side of the pump, feeding into a liquid cyclone to blend evenly with
any water.
Note: The UV scanner signal is connected to the Flame Safety, which
produces a 0-5 VDC signal. This signal is sent to a PID controller
producing a 4-20ma signal to operate the mixing valves. An over-ride
will hold the valves to #2 oil only until the "At Temp" is reached.
Control Components
This package includes one (1) Hoffman Nema 4 control panel, for remote
control and monitoring and maintains a preset temperature utilizing a
type K T/C and 4-20ma digital controllers. System is monitored and
operated with Honeywell DC-3000 temperature controllers located in the
main panel. All controls and safeties are operated from the main panel
as the controller modulates the gas to maintain temperature. Contacts
will be provided for remote start and stop, pressure limit switch and
for the motor starter coil.
