VIRTUAL ENERGY AUDIT Your Power Plant on a desktop computer Alan Werner, P.E.

(Value Added by Werner)
COMPLEX ENVIRONMENT
HISTORICAL FACTORS
OPERATIONS BASED MAINLY ON INTUTION AND EXPERIENCE INSTRUMENTS PROVIDE THE MOST IMPORTANT DATA IN A VARIETY OF FORMATS ADEQUATE METHODS TO DATE NOTHING WRONG – BUT CAN BE IMPROVED
CONSEQUENCES
INCOMPLETE PICTURE OF THE ENTIRE PLANT OPERATIONS RECORDS REFLECT ONLY A PORTION OF THE EQUIPMENT FORECASTING, PREDICTIONS, AND ESTIMATIONS ARE EMPIRICAL (BASED ON EXPERIENCE)
VEA SOLUTION: The Virtual Energy Audit
Whole plant basis – all parts working together Calculation with accounting leading to energy balance A virtual energy audit (balance) on demand Uses MS Excel – simple and direct
BASIS ENERGY IN = ENERGY OUT* * Product (Delivery) + Losses + Work LOSSE S INPUT
DELIVERY
FUNDEMENTALS STOICHIOMETRIC COMBUSTION (the secret)
Water at temp + heat Steam at pressure BTU (British Thermal Unit): fixed unit Requirements from feed to output in a boiler is known and able to be calculated
FUEL The fuel shown is natural gas (CH4 mostly) Solid Fuel (wood) given local data Coal is common Oil fuel given characteristics Key: heating value at firing conditions
A LITTLE THERMODYNAMICS
Natural Gas – most uniform CH4 + 2 O2 CO2 + 2 H2O 1 LB MOLE CH4 = 337,775 BTU/lb mole ±
OIL - Varies by grade
Wood – Varies by species, moisture, and dirt
137,000 – 150,000 BTU/gal 8400 – 11,300 BTU/lb (dry), 8750-874 BTU/lb (wet)
Coal – Varies by type and location
9300 – 14,700 BTU/lb
COMBUSTION SHEET
STOICHIOMETRIC BENEFITS
Creates known requirements to heat water, add latent heat, and generate steam conditions Calculates combustion environment Air flow Flue conditions Residual O2 Excess air Efficiency contribution
Can accommodate blowdown and radiant heat losses
PLANT PROCESS DIAGRAM THE START
TOUR
LOOK AT THE INTERNALS OF THE VEA GET A FEEL FOR THE PARTS LEAD TO MORE DETAILED DEMONSTRATION
SCHEMATIC SHEET
GOLD AND YELLOW BOXES = INPUT
OPERATOR LOG
OVERALL
BOILER #2
TYPICAL FOR INDIVIDUAL UNITS
HEAT RECOVERY CONDENSING ECONOMIZER
PLANT USES 1 THERMODYNAMI C PARAMETERS
PLANT USES 2 COMMON EQUIPMENT
PLANT USES 3 COMMON EQUIPMENT
MASS BALANCE
ENERGY BALANCE The Bottom Line
PAUSE SO, WHAT WAYS WOULD YOU SEE TO MAKE THE VEA WORK FOR YOU? (There is no quiz, therefore there is no pressure.)
FEATURES
Stand-alone program or integrated into an automated control program Adaptable to future changes to remain unique to a specific plant Operates in many modes (see later) Accounts for all significant equipment Fans, Pumps, Deaerator-heaters, Pre-heaters, Economizers, Heat Recovery, Generators, Hot wells, Turbines/motors, chillers, pulverizers, and more…
TOOLS
OPTIMIZER – FORECASTING OPERATING EFFICIENCY DOCUMENTATION – RECORDS FOR TOTAL PLANT EQUIPMENT MODIFICATIONS – RESEARCH W/O HIGH COST AUTOMATION TRAINING TOOL
TRAINING TOOL Overall
Specific Customized simulation of the specific power plant to learn how to operate and optimize quickly and without actual operation.
