25 Ash Formation Partitioning 25
26 Ash Particle Size and Composition Distribution Na and Ca rich 26
27 How do deposits form in boilers? Transport of particles and vapor phase material to the surface Sticking to the surface sticky material formation 27
28 Ash Transport to Heat Transfer Surfaces The transport of intermediate ash species (inorganic vapors, liquids, and solids) is function of: State and size of the ash species System design burner type, heat transfer surface configuration System conditions, such as gas flow patterns, gas velocity, and temperature 28
29 Ash Transport Mechanisms eddy 29
30 Sticking and Bonding Phases 30
31 Silicate Viscosity: Slag Flow, Particle Sticking, Deposit Strength 31
32 Wall Slagging Wall Slagging (hightemperature bonding phases) Indicates propensity of deposits to accumulate on the radiant walls of a boiler Temperatures from 2000 to 3000 F (1093 to 1649 C). Slagging Convective pass fouling High temperature Low temperature Burners 32
33 Deposit Thickness T-fired boiler Ma, Inman, Lu, Sears, Kong, Rokanuzzaman, McCollor, Benson, Fuel Processing Technology 88 (2007)
34 Convective Pass Fouling Silicate (high temperature) Occurs in high-temperature convective pass Temperatures between 1600 and 2400 F Silicate-based deposits Convective pass fouling High temperature Low temperature Sulfate (low temperature) Low-temperature convective pass Temperatures between 1000 and 1700 F Sulfate-based deposits Slagging Burners 34

37 Deposit Sampling and Analysis 37
38 Boiler Design for Lignite 38
39 Effects of Rank and Coal Type on Boiler Sizing 39
40 Important Design Criteria for the Furnace Net heat input per furnace plan area (Btu/hr-ft 2 ) Vertical distance from top fuel nozzle to furnace arch Distance is function of furnace width and depth Furnace dimensions must provide residence time to: Properly burn fuel Cool the combustion products Function of body of the boiler (radiative heat transfer)
41 Important Factors in Convective Pass Fouling Erosion can be diminished by minimizing gas velocities. Fouling can be reduced by: Sootblowing - Air for low-fouling situations - Steam for high-fouling situations - Pulsed detonation - Acoustic horns Lower heat release rates (large furnace volume) Greater number of wall blowers to minimize wall slagging Higher excess air levels Greater number of retractable sootblowers in the convective pass Increased tube spacing Additives

47 Comparison of observed with predicted fouling behavior 47
48 Summary - Lignite Property Impacts Moisture lowers heating value, increases volume of gas in combustor, changes where heat is absorbed Volatile matter lower volatile matter decreases ability to stage and reduce NOx Ash increase lowers heating value Higher basic ash (Na, Mg, Ca, K, Fe) (low ash contents) fine particle formation, reflective ash in boiler, higher furnace exit gas temperatures, increased convective pass fouling, higher opacity Higher acidic ash (Si, Al, Ti) (higher ash contents) larger ash particle formation, wall slagging, high-temperature convective-pass fouling, lower low-temperature convective-pass fouling, lower opacity Blending significant opportunity to improve the efficiency/reliability and decrease CO 2 intensity 48
