Definitions

  • the present invention relates generally to the field of industrial burner apparatuses for performing combustion functions for power generation.
  • biomass describes a wide range of organic matter derived from diverse living, or recently-living organisms, such as grasses and wood products.
  • Sources of biomass include trees, shrubs, bushes, residual vegetation from harvesting grains and vegetables.
  • Biomass is commonly plant matter harvested to generate electricity or produce heat.
  • Biomass may also include biodegradable wastes of organic origin that can be burned as fuel.
  • Biomass differs from fossil fuels, which are hydrocarbons found within the top layer of the Earth's crust. Common examples of fossil fuels include coal and oil. Unlike fossil fuels, biomass fuels are generally considered CO 2 neutral and renewable resources, since CO 2 generated from biomass combustion can be removed from the atmosphere by the plants that provide the biomass.
  • biomass fuels for power generation have historically been utilized as a primary or auxiliary fuel in stoker and fluid bed style boilers. Such boilers do not rely on burners thereby enabling significantly higher furnace residence time for combustion and consequently have less stringent fuel preparation requirements.
  • Pulverized coal firing is the primary means of suspension firing in the power generation industry.
  • coal is mechanically pulverized into fine particles.
  • the particles are then subsequently conveyed via suspension in a primary air stream to a burner, wherein the burner ejects the air/fuel mixture in a furnace for combustion.
  • Residence times are nominally 1 to 2 seconds, which is normally sufficient for complete pulverized coal combustion with proper particle sizing.
  • Biomass firing in pulverized coal-fired boilers is becoming more widespread as a strategy for reducing greenhouse gases.
  • Firing biomass fuels faces many technical challenges. As compared to bituminous coal, biomass fuels have significantly lower heating values and a higher concentration of volatile matter. Heating value is inversely proportional to moisture content, such that it amounts to 25% to 75% that of a typical bituminous coal. Biomass moisture will often be reduced prior to firing for material handling reasons and to improve process efficiency and capacity. Nevertheless, firing biomass in place of coal requires considerably more fuel mass to achieve a comparable heat output. Further, while the highly-volatile nature of biomass makes the fuel inherently easy to burn, the high moisture content can delay ignition. Delayed ignition is especially undesirable in suspension firing,
  • biomass fuels are not processed to the same particle size as pulverized coal.
  • wood particles sized 1.59mm (0.0625 in). compared to the top size for pulverized coal of 0.30mm (0.012 in). Particle volume varies by the diameter cubed, thus wood particles have approximately 150 times the volume of larger coal particles used for suspension firing.
  • the larger volume of the biomass thus requires quick ignition and rapid combustion to enable use of biomass in furnaces designed for pulverized coal firing.
  • biomass co-firing One known technique of utilizing biomass in suspension firing is biomass co-firing.
  • biomass particulate is combined with pulverized coal and primary air in a single stream.
  • the combined stream is then introduced into the furnace.
  • This technique is however limited in practicality due to the resulting burner nozzle velocity necessary to maintain both types of particles in suspension. Excessive burner nozzle velocity results in flame instability, delayed ignition, and poor combustion performance.
  • US 5,697,306 describes a burner for the combustion of a pulverized coal plus primary air mixture that includes a nozzle pipe having an inlet for receiving a pulverized coal plus primary air mixture and an outlet for discharging same.
  • a hollow plug extends axially within the nozzle pipe and defines an annular space between the plug and the nozzle pipe for conveying the pulverized coal plus primary air mixture therethrough.
  • the hollow plug is axially moveable within the nozzle pipe.
  • a variable amount of core air is supplied into the hollow plug so that it mixes with the primary air plus pulverized coal mixture at an outlet of the burner to vary the PA/PC ratio and maintain a desired primary air to primary coal ratio at the outlet of the burner.
  • Natural gas can also be supplied into the hollow plug as a supplemental fuel for cofiring at the outlet end of the burner.
  • the amount of core air supplied is based upon (1) the coal flow rate being provided to the burner, in lb/hr, and (2) the percent volatile matter content (%VM) in the coal being burned.
  • WO01/25689 describes a method of co-firing biofuel in a boiler designed for burning a fossil main fuel such as coal, brown coal or peat, the method comprising the steps of first grinding the main fuel for burning, then feeding the main fuel with the help of a carrier gas into at least one burner, and burning the main fuel in the boiler combustion chamber. After the grinding of the main fuel, biofuel is mixed into the flow of the pulverized main fuel prior to the feed of the fuel mixture into the burning flame, whereby the biofuel is co-fired with the main fuel in the same flame.
  • the biofuel may be hog wood, straw, fuel separated from community waste or other available biomass.
  • a combustion apparatus capable of firing biomass fuel and alternating between biomass and coal firing, as needed, and/or combusting a combination of coal and biomass fuels concurrently.
  • a device for combusting renewable fuels including, but not limited to, biomass.
  • a combustion apparatus capable of firing biomass fuel including a burner assembly which includes a biomass nozzle concentrically surrounded by a core air zone and extending axially along the length of the core air zone, the burner assembly residing within a windbox, the windbox being attached to a furnace of a boiler, and the burner assembly being connected to the furnace by a burner throat, through which air and fuel supplied to the burner assembly are emitted into the furnace.
  • the apparatus can include some or all of a forced draft fan providing a first supply of air to the windbox, a core air duct, enclosing the core air zone, for receiving a core portion of the first supply of air, the core air duct having a core damper for regulating the core portion entering the core air duct, a core nozzle for receiving the core portion from said core air duct, the core nozzle delivering said core portion to said burner throat, a burner elbow for receiving pulverized coal and a second supply of air, the pulverized coal and said second supply of air continuing through a coal nozzle in an annulus formed between the core nozzle and the coal nozzle, the core portion serving to accelerate ignition of pulverized coal by contacting an inner cylinder of a coal jet leaving the coal nozzle, the core portion also serving to accelerate combustion.
  • a forced draft fan providing a first supply of air to the windbox
  • a core air duct having a core damper for regulating the core portion entering the core air duct
  • Fig. 1 shows a burner assembly 1 residing within windbox 2, which is attached to the furnace 3 of a boiler (not shown).
  • Secondary air 22 is provided to windbox 2 by a forced draft fan (not shown) and heated by an air preheater (not shown).
  • the burner assembly 1 is connected to furnace 3 by burner throat 4, through which air and fuel supplied to the burner assembly 1 are emitted into the furnace 3.
  • a portion of the secondary air 22 constitutes core air 5.
  • Core air 5 enters core air duct 6 and is regulated by core air damper 7.
  • Core air 5 continues through the burner assembly 1 through core nozzle 8, exiting through the burner throat 4.
  • Secondary air 22 is also supplied to the burner assembly (designated as secondary air to the burner assembly 9). Secondary air 22 enters the burner assembly 1 and travels through parallel flow paths of the inner air zone 10 and outer air zone 11. Swirl vanes in these zones serve to swirl secondary air 22 to facilitate ignition and combustion of secondary air 22 contacting the pulverized coal stream.
  • An air separation vane 12 at the exit of outer zone 11 acts to increase the size of an internal recirculation zone (IRZ) formed by resultant aerodynamics.
  • Pulverized coal and primary air 13 enter burner elbow 14 and continue through coal nozzle 15, in the annulus formed between core nozzle 8 and coal nozzle 15.
  • the core air 5 serves to accelerate ignition of pulverized coal by contacting the inner cylinder of the coal jet (not shown) leaving the coal nozzle 15; and serves to accelerate combustion by a "bellows effect" supplying air to the center of the flame.
  • LaRue '970 provides a detailed discussion on the accelerated ignition relating to core air.
  • the burner assembly 1 may be operated in combination with an over-fire-air (“OFA") system (not shown).
  • OFA over-fire-air
  • a portion of the secondary air 22 supplied to the furnace for combustion is supplied to the OFA system, such that the total amount of air supplied to the burner assembly 1 is less than theoretical air requirements. This produces a reducing environment in the furnace before OFA is supplied.
  • the accelerated combustion, higher temperature flame, and larger IRZ all serve to more effectively reduce NO x under reducing conditions.
  • biomass may be prepared for suspension firing using shredders, hammer mills and the like (not shown), collected and regulated in feed rate by a screw feeder or equivalent device (not shown) and pneumatically conveyed to the burner assembly 1 through an appropriate conduit.
  • the conduit supplies biomass and transport air 16 through an elbow whose outlet is situated at the axis of the burner 1.
  • a reducer 17 may be used to reduce the cross-sectional area of biomass nozzle 18 as the nozzle transverses the burner elbow and continues past the core air duct 16.
  • a reducer 17 serves to lessen the flow obstruction as the biomass nozzle 18 extends through the length of the burner assembly 1.
  • the biomass nozzle tip 19 diameter can be expanded as shown ( Fig 1 .) to reduce the biomass exit velocity to the optimum value for combustion. In certain embodiments, this exit velocity is between about 13 m/s (2500 ft/min) and about 25 m/s (5000 ft/min), and in further embodiments is between about 15 m/s (3000 ft/min) and 20 m/s (4000 ft/min).
  • core air 5 surrounding the biomass nozzle tip 19 serves to accelerate ignition of the biomass as it enters the burner throat 4, and supplies air to feed combustion as the biomass continues into the furnace.
  • the hot secondary core air that surrounds the biomass nozzle provides heat to enable additional moisture removal from the biomass fuel while supplying the fuel with an oxidant to facilitate ignition and combustion. This contributes to avoiding delayed ignition and/or combustion of biomass.
  • Core air damper 7 can be adjusted to supply core air 5 in such quantity so as to minimize NO x emissions when firing biomass in combination with pulverized coal.
  • the biomass supply system (not shown) serving the burner assembly 1 can be shut down and valve 23 closed.
  • Valve 21 can then be opened and adjusted in combination with core damper 7 to supply the optimum amount of core air 5 necessary for minimizing NO x when firing the particular coal.
  • valve 21 is shut and valve 23 is opened to admit biomass and transport air 16.
  • FIG.4 a schematic cross section of the burner assembly 1 is shown wherein the five distinct zones of the burner assembly 1 are identified.
  • a biomass zone 32 defined by biomass nozzle 18 is concentrically surround by a core air zone 44 defined the area between biomass nozzle 18 and core nozzle 8.
  • a coal nozzle 15 concentrically surrounds core nozzle 8 defining a first annular zone 47 wherein pulverized coal and primary air (PC/PA) 13 flows.
  • a barrel 42 concentrically surrounds coal nozzle 15 and defines the inner air zone 10 internal to barrel 42 and an outer air zone 11 external to barrel 42.
  • Such alternative arrangements can include a straight pipe without reducer 17, and/or without expansion at the furnace end of biomass nozzle 18.
  • FIG. 2 an alternative approach of a shorter or recessed biomass nozzle 18 is shown.
  • the biomass nozzle tip 19 terminates within the core nozzle 8 near the core air duct 6.
  • This embodiment provides for preheating and premixing the biomass with the core air, thereby further enabling additional moisture removal from the biomass fuel.
  • a reducing taper may be used at the exit of the biomass nozzle 18 as shown in Fig 3 . This provides acceleration of the biomass fuel as it enters the furnace 3 which can reduce the risk of flashback into the biomass nozzle 18.
  • biomass nozzle 18 is illustrated as an open-ended nozzle in the figures, it may be fitted with deflectors or swirlers near the exit to increase mixing rate of biomass with core air.
  • adjustment means may be included to facilitate minor fore/aft adjustments in the end position of the biomass nozzle 18 relative to the core pipe to enable further optimization of combustion. While the biomass nozzle 18 is shown flush with the end of the core pipe in Figure 1 , it may also be positioned slightly further back or further forward.
  • valve 21 may be used to admit a small amount of air, either hot secondary air or unheated air, to add air to the center of the flame while firing biomass. This can augment center stoichiometry for reducing NO x generation (as alternative to increasing transport air quantity).
  • Certain embodiments of the disclosed concepts can provide beneficial performance for firing of biomass fuels.
  • the large core zone provided in the burner arrangements discussed above can accommodates a biomass nozzle without changing the overall burner size. This can save the engineering and manufacturing costs associated with building burners of different sizes to accommodate biomass firing.
  • the large biomass nozzle provided in the burner arrangements described above can enable firing larger quantities of biomass in selected burners, such that fewer burners need be supplied to fire biomass. For example, biomass firing rates up to 40% of rated burner input enable boiler biomass firing rates of 20% while using only half the number of installed burners.
  • biomass fuel availability can vary over different times of the year such that biomass firing may not always be conducted continuously.
  • the biomass nozzle can be supplied with secondary air when not firing biomass such that both the biomass nozzle 18 and core nozzle 8 provide a combined core air jet for the combustion of pulverized coal.
  • the transport air with biomass can contribute to a target or preferred center stoichiometry of the burner when firing biomass in combination with coal.
  • the coal flow can be reduced such that a higher PA/PC ratio is supplied to the burner.
  • This can augmented with transport air from biomass to provide a center stoichiometry conducive to very low NO x emissions.
  • the locating of the biomass nozzle in the core zone can provide a source of hot secondary air for igniting and feeding combustion of the biomass fuel, thus preventing delayed ignition as well as feeding combustion of the co-fired biomass fuel.
