A tube coil for a double fired coker heater wherein the tube coil has at least two independent flow passes in an intertwined serpentine pattern. The tubes are located in a common plane and plumbed in parallel with one another. These tube coils can be used in a number of configurations within the radiant section of a coker heater.

A system and method whereby on-line cleaning of black oil heater tubes and delayed coker heater tubes may be effectuated by injecting a high pressure water charge through the tubes during normal process operations so as to prevent tube fouling and heater downtime. The high pressure water charge begins the on-line cleaning process once it enters the heater tube by undergoing intense boiling and evaporation. The cleaning occurs by two methods&#x2014;a scrubbing action and a shocking action. The scrubbing action occurs because of the complete turbulence caused by the water charge's intense boiling within the heater tubes. The shocking action is caused by the expansion and contraction of the heater tubes resulting from the colder water charge flowing through the heater tubes which is then followed by the hotter process fluid flowing through the heater tubes.

A method and apparatus whereby flameless combustion may be precipitated and sustained within the essentially oval combustion chamber of an integrated heater/burner apparatus. The invention provides for an air inlet and fuel source in combination with recirculating flue gas within the apparatus combustion chamber to precipitate and maintain flameless combustion of the combined gases along, and within, a narrowly defined boundary. Air is introduced to the oval combustion chamber via an air inlet. Fuel gas is combined with recirculating flue gases with continued heating of the recirculating flue gas, introduced air or both flue gas and air, until the temperature at the boundary interface between the air and inerted fuel gas exceeds an auto ignition temperature of the boundary interface components. A fuel gas stream absent a flamed portion thereof is combined with the recirculating flue gas and then allowed to diffuse with the air stream in a measure sufficient to sustain flameless combustion and chamber operational temperature of generally between 1500&deg; F. and 1900&deg; F. The essentially oval configuration of the integrated heater/burner allows for increased mass and circulation rates beyond that possible with heaters of the contemporary art and as a consequence thereof provides for uniform, complete and cooler combustion resulting in low NOx emissions.

The tubular housing has a generally frusto-conical shape. A peripheral lip is attached to and extends around an edge of the first open end. A sleeve for extending into the first open end of the housing has a first end, a second end and a peripheral wall extending between the first and second ends. The first end of the sleeve is open and has a perimeter edge has a flange thereon. The flange comprises a hook extending toward the second end. The flange may be extended over the lip on the housing for rotationally coupling the sleeve to the housing.

A system and method to improve the efficiency of delayed coker charge heating by effecting and controlling the temperature of a coker process fluid, prior to its introduction to a coker charge heater. In its preferred embodiment, the instant invention strategically positions and controls a pre-heater to automatically stabilize and minimize delayed coker charge heater firing rates. Said pre-heater's set point is derived by a feed forward control system that allows for the detection of process fluid temperature within a combination tower bottom, and communicates that temperature value to a pre-heater. Based upon the temperature value communicated to the pre-heater, the pre-heater intensifies, maintains, or decreases its firing to effect an operationally consistent combination tower bottoms temperature. By maintaining nearly constant combination tower bottoms temperature, a delayed coker charge heater derives enhanced operational efficiency and increases its life expectancy. Such benefits result from a nearly constant coker charge beater process fluid inlet temperature and optimized coker firing rates.

A probe for determining the heat flux in a direct-fired heater. The direct-fired heater is under a vacuum pressure. This vacuum pressure induces a small quantity of ambient air through a ceramic insulating tube and eventually into the heater. The induced air cools an absorber head and receptacle, causing heat to flow from a target to a base. The target is an outer surface of the absorber head exposed to radiant heat inside the direct-fired heater. The base is that portion of the absorber head and receptacle which has a surface exposed to cooling air within the ceramic tube. The vacuum pressure inside the heater causes ambient air to be induced into a second end of the ceramic tube. Air passages at a first end of the ceramic tube cause the induced air to flow past the base and into the heater. A thermocouple is fitted into a cylindrical slot inside the receptacle. First and second thermocouple wires extend from the thermocouple to a weatherhead, which has electrical contacts which connect to the first and second thermocouple wires and to instrumentation, such as a digital meter or other input, output device such as a microprocessor or computer for monitor and control of heat flux. After measuring the thermocouple temperature in the receptacle, one can then determine the heat flux through the target by experimental correlations.

In a delayed coking process, furnace tube fouling is minimized by including a measured amount of full boiling range heavy gas oil as an additive in the furnace feed, preferably by forced recycle from a heavy gas oil stream. An additive is preferably supplied directly to individual furnace tubes by multiple circumferential injection upstream of each tube receiving the additive.

Reduction of coker furnace tube fouling in a delayed coking process

An improved process and article of manufacture to advance heater performance and reduce the cost of delayed coker charge heaters. Such improved performance is realized by routing delayed coker feedstock through a double row, double fired, heating conduit thus creating a channel to contain previously heated flue gas and resulting in the introduction of downflow, backside convective heat transfer to the interior portion of the heating conduit. When replacing the present art's single row coker tubes with the double row heating conduit afforded by the instant invention, the backside convective heat transfer introduced to the interior portion of the heating conduit eliminates the necessity of double firing the present art's single row coker heater tubes to achieve similar results.

An improved process and article of manufacture to effectuate pressure reduction in a delayed coker charge heater's radiant heat section outlet and feedstock process coil, by upflowing coker feedstock through a single or double row, single or double fired, feedstock process coil. The innovative upflowing of coker feedstock as disclosed by the present invention allows BFW/Steam injection and vaporizing hydrocarbons to rise in the same flow direction as the coker feedstock, resulting in an enhanced mixing of fluid film and coker feedstock. Such enhanced mixing, in turn, increases heat transfer rates to the feedstock. As coker charge heater burners are commonly located in the bottom of the heater, the lower portion of the heater is typically the location of highest processing temperatures and tube side fouling. Upflowing the process coil places migrates the hottest processing section to a cooler location in the heater, and thus, contributes to conditions which reduce coking/fouling rates within the feedstock process coil, increase feedstock process coil tube life, reduce tube skin temperatures, and increase run time between decoking the interior portion of the feedstock process coil.
