Novacon Energy Systems, Inc. The TAMS Flue Gas Multi-Pollutant Control System For conventional utility boilers, TAMS holds the promise of extending the useful life of the plant while simultaneously reducing emissions and meeting higher future demand for electric power at competitive prices. For smaller utility boilers it would allows for substantial emissions Reductions without the high capital, labor, maintenance, and Operating costs associated with scrubbers. For Circulating Fluidized Bed combustors  it would significantly reduce  costs, increase efficiency, increase plant output, and provide for very high emissions reductions without additional capital investment. TAMS very low capital cost significantly reduces the financial risks of facilities planning and pollution control cost containment strategies. It may be used in any type of combustor and is applicable to Waste to Energy plants, Paper manufacturing, and many other industrial applications.
THE NOVACON SORBENT INJECTION PROCESS   Thermally Active Marble (TAM (c) )   WHAT IS IT ?  A specially selected and prepared form of Calcium Carbonate exhibiting greatly increased performance as compared to conventional Limestone,Hydrated lime, Sodium Bicarbonate, and other sorbents
TAMs Dynamics Why does it outperform other in-furnace or in-duct sorbents?   ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
TAMs Injection into CFB or PCB TAMS can be used in  any type of combustor  through a simple system consisting of a silo, a metering valve, and pneumatic injectors. Drawing shows schematic for the majority of installed boiler types Works well in Stoker-Grate, Rotary Kiln and Mixed-with-Coal- Systems
Novacon Process Schematic for P.C.B. boilers For C.F.B.s no equipment needed since they are already equipped for limestone injection Feed Stone Supply Grinding & Processing Equipment Grinding & Processing Equipment Two production lines for increased reliability TAMs Silo Variable speed Feeder Boiler Combustor Injectors * * Closed-Loop Control System Feed rates would be automatically controlled by CEMS stack sensor data vs. Emissions Set-Point
THE ADVANTAGES OF THE NOVACON TAMs FLUE GAS DESULFURIZATION SYSTEM FOR PULVERIZED COAL BOILERS (PCB) ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
Comparison of TAMs to Limestone in Pulverized Coal Boiler Demonstrations Firing 2.48% Sulfur Bituminous Coal % SO 2  Capture at Ca/S of 2   Test performed under the sponsorship of the U.S. Dept. of Energy and The Illinois Clean Coal Institute at EERC (General Electric). Over 500 limestones tested in this program. Showed 78% reductions @ 2 CA/S at Penn State firing same coal.
THE ADVANTAGES OF TAMs IN CIRCULATING FLUIDIZED BED (CFB) COMBUSTORS IN PLACE OF LIMESTONE ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
CFB Pilot Scale Test Please note: SO2 reductions with TAMS higher by 1.8% Difference in feed rates would have been higher at same reduction rate  Results of Demonstrations in CFB Power Plants Ca/S ratios required to meet SO2 reduction targets. Over 1 year in use at Foster Wheeler, AES, Tampella,
Superior Performance allows the option of using less expensive higher-sulfur fuels in CFBs while still meeting very stringent emission standards ,[object Object],[object Object],[object Object],[object Object]
TAMs Compared to Other Sorbents Higher temperature tolerance without sintering and flatter curve This allows it to be injected closer to the flame which increases residence time and assures higher mixing efficiencies of SO2, coal, and sorbent    Temperature conversion- 2200 F = 1204 C  2300 F = 1260 C  2400 F = 1316 C  2500 F = 1370 C
Tests run at EERC   Key Operating Results  Firing 2.5% Sulfur Illinois Coal (EERC is a subsidiary of General Electric) 2450 F = 1343 C  Flue gas V = 2.15 m/s
Cost/Benefit Issues and Implications  ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
TAMs  (c)   Can be used at Coal and Oil Burning  Power Plants as the Transformation Technology to a Cleaner, Greener Environment
