Description
- The present application and resultant patent relates generally to gas turbine engines and more particularly relate to an in-line bio-diesel blending system that creates any desired blend of bio-diesel with other fuels without the use of a mixing tank so as to promote fuel flexibility.
- Heavy duty gas turbine engines may operate on a number of different fuels. Power plants thus may have gas turbine engines with multiple fuel capacity and may operate on, for example, diesel or natural gas. The specific fuel in use may be chosen depending upon availability, price, and other operational parameters. Moreover, there is an increased interest in renewable sources of fuel such as “bio-fuel” or “bio-diesel” fuel. Bio-fuels and diesel fuels, however, generally must be premixed before combustion. The fuels may be premixed in a number of different techniques that provide little flexibility in altering the specific proportions of the bio-diesel fuel to the diesel fuel. Moreover, a large mixing tank may be required for each proportion or blend of the fuels to be used.
- There is thus a desire for systems and methods for the accurate preparation and delivery of bio-diesel fuels and blends thereof to a gas turbine engine. Such systems and methods may provide fuel flexibility for the gas turbine engine to operate on multiple fuels and any type of blend thereof.
- The present application and the resultant patent thus provide a bio-diesel blending system for blending a flow of a bio-diesel fuel with a flow of a second fuel. The bio-diesel blending system may include one or more second fuel skids with the flow of the second fuel therein, a bio-diesel tank with the flow of the bio-diesel fuel therein, a bio-diesel skid in communication with the bio-diesel tank, and one or more blending lines in communication with the bio-diesel skid and the second fuel skids for in-line blending of the flow of the bio-diesel fuel and the flow of the second fuel to form a blended fuel flow.
- The present application and the resultant patent further provide a method of in-line blending of a flow of bio-diesel and a flow of distillate. The method may include the steps of flowing the distillate along a diesel skid, storing the bio-diesel in a bio-diesel tank, flowing the bio-diesel through a blending line, in-line blending the bio-diesel and the distillate into a blended fuel, and flowing the blended fuel towards a combustor.
- The present application and the resultant patent further provide a bio-diesel blending system for blending a flow of a bio-diesel with a flow of a distillate. The bio-diesel blending system may include a diesel fuel skid with the flow of the distillate therein, a bio-diesel tank with the flow of the bio-diesel therein, a bio-diesel skid in communication with the bio-diesel tank, and a blending line in communication with the bio-diesel skid and the distillate skid for in-line blending of the flow of the bio-diesel and the flow of the distillate to form a blended flow.
- These and other features and improvements of the present application and the resultant patent will become apparent to one of ordinary skill in the art upon review of the following detailed description when taken in conjunction with the several drawings and the appended claims.

Thepositive displacement pumps 170 may have any size or capacity. In this example, three fifty-percentpositive displacement pumps 170 are shown although other types of pumping devices may be used herein. Other components and other configurations may be used herein. - The
bio-diesel heater 150, the self-cleaningfilters 160, and thepositive displacement pumps 170 have positioned on abio-diesel skid 180 or elsewhere. Thebio-diesel skid 180 may be of any size, shape, or configuration. Thebio-diesel skid 180 may be positioned adjacent to thebio-diesel tank 110 or elsewhere.

The blending lines 190 may extend from thebio-diesel skid 180 to a T-joint 220 or another type of a flow divider. Eachblending line 190 then may continue to one of the diesel skids 50 at an in-line joint 225. In this example, the blendinglines 190 may tie in at the in-line joint 225 upstream of the low pressure filters 85. Other types of tie in points may be used. - Each
blending line 190 may have one ormore control valve 230 thereon. Thecontrol valve 230 may be in communication with a bio-diesel recirculation line 240.

bio-diesel blending system 100 permits the in-line blending of any percentage of thebio-diesel fuel 120 with thedistillate 60 without the use of a blending tank. Specifically, thebio-diesel heater 150 may heat thebio-diesel fuel 120 to a temperature well above its pour point. The self-cleaningfilter 160 may remove impurities from thebio-diesel fuel 120. The bio-diesel pumps 170 then may pump thebio-diesel fuel 120 at a desired flow rate and at the desired pressure through theblending lines 190 into the main flow of thedistillate 60 at the in-line joint 225 to form a blendedfuel 290. Thecontrol valves 230 may only allow the required flow rate based on input on the mainstream flow rate and/or the total flow rate as well as feedback from thebio-diesel flow meters 270. The remainingbio-diesel 120 flow may be recirculated to thebio-diesel heater 150 or elsewhere. The blendedfuel 290 may have any percentage of the bio-diesel 120 therein such a B20, B30, and the like. - The
bio-diesel blending system 100 thus provides the blendedfuel 280 with any percentage ofbio-diesel fuel 120. The blend ratio may be varied almost instantaneously. Moreover, thebio-diesel blending system 100 controls the overall injection rate and blend therein. Thebio-diesel blending system 100 thus avoids the cost of a conventional blending tank or mixing chamber while providing accurate fuel blends. The use of thebio-diesel blending system 100 further permits the creation of bio-diesel blends while also allowing the gas turbine engine to operate on a flow of the distillate and/or on a flow of natural gas. Thebio-diesel blending system 100 thus provides further fuel flexibility in a highly efficient system. -
FIG. 4 shows a further embodiment of abio-diesel blending system 300 as may be described herein. In this example, thebio-diesel blending system 300 may tie into the diesel skids 50 directly downstream of thebio-diesel heater 150 and thedistillate heater 70 or elsewhere. Instead of using the bio-diesel pumps 170, aneductor 310 may be used for the pumping action via aneductor line 320. Theeductor 310 is a mechanical device without any moving parts. Instead, theeductor 310 mixes two fluid streams based upon a momentum transfer between a motive fluid and a suction fluid. A motive inlet may be in communication with the flow ofdistillate 60 under pressure. Theeductor 310 also may include a suction inlet. The suction inlet may be in communication with the flow ofbio-diesel 120. The flow offuel distillate 60 thus may be the motive fluid that provides suction for the flow ofbio-diesel 120. The flow ofdistillate 60 enters the motive inlet as the motive flow and is reduced in pressure below that of the flow ofbio-diesel 120 as the suction flow is accelerated therewith. The flows are mixed in theeductor 310 and exit the blendedfuel 290. Although other types of mixers, mixing pumps, and the like may be used as theeductor 310. The use of the eductor 310 further simplifies thesystem 300 with the elimination of the pumps and like. Other components and other configurations also may be used herein. - It should be apparent that the foregoing relates only to certain embodiments of the present application and the resultant patent. Numerous changes and modifications may be made herein by one of ordinary skill in the art without departing from the general spirit and scope of the invention as defined by the following claims and the equivalents thereof.
