Boiler Efficiency vs Fluid Mechanics Calculator

BoilerFE can run a quick preliminary audit on boiler efficiency and various losses associated in generation of pressurized steam. Users can create their specific boiler application including CHP (Brayton) cycle by editing default generic boiler and save it in a file for time to time performance review. Thus it would also enable users to compare different grade of fuels used in the same boiler under similar conditions. Therefore, this app can be very helpful to energy engineers and auditors in assessing the potential savings as well as to identify areas for improvement. App covers different types of boilers including CHP with option to select fuels such as coal, oil and gases with specific compositions. Following is the list of fuels under each category one can select from the picker. Each fuel has a default calorific value (HHV) based on certain composition. Users can edit this default value for accuracy. For fuels that are not in the list, users can create a custom fuel with composition and calorific value. Coal: Coal-Illinois, Coal-Pennsylvania, Coal-Ohio, Coal-W.VA, Coal- Kentucky, Coal, Custom. Fuel Oil: Furnace Oil#1, Furnace Oil#2, Furnace Oil#3, Furnace Oil#4, Furnace Oil#5, Furnace Oil#6, LSHS, Methanol, Ethanol, LPG, Kerosene, HSD, Custom. Gas: Methane, Ethane, Propane, Butane, Natural gas, Custom. By default, App uses a generic Coal fired in an industrial boiler that can be edited for more specific applications. The screen shots displays this example with results on heat balance sheet, flue gas analysis and stoichiometry. A brief description of the combustion model used in this app is also provided in App notes for reference. Type of boilers and inputs: App covers packaged, industrial and utility boilers with specific design data for efficiency and heat balance calculations. Users can conveniently choose the different unit standards for data input. Input such as airflow, fuel type and feed rate can be edited for more specific application using the respective editable tool bar buttons. There is a separate section on CHP (Brayton) cycle that is activated from Boiler info screen. All CHP data can be saved as well with unique titles and reloaded as and when required. Foot notes are provided to help edit different input parameters. Result: Besides computation of boiler efficiency using direct method, app provides the following results as shown in the screen shots. 1.Heat balance sheet 2.Flue gas analysis 3.Stoichiometric analysis of the combustion process. In this version, the app notes has the link for a complete documentation of implementation and validation of math-model used in individual apps. Also in addition this document includes guidelines to plan periodic maintenance activities required for a satisfactory performance of different energy intensive equipment such as boiler, pump, heat exchangers etc. commonly used in process industries.

Fluid Mechanics Calculator contains 97 calculators to compute different Fluid Mechanics and Civil Engineering parameters — now with a solve-for-any-variable engine: in every calculator, choose the value you want to find and enter the rest. Available in both USCS (Imperial Units) and SI (Metric Units). What's new in this version: • Filter calculators by category — pressure, open channel, pipe, groundwater, pump, and dimensionless numbers • Solve for any variable — pick the unknown in each calculator; no more fixed inputs and outputs • Share any calculation as an image Features: • 97 Fluid Mechanics and Civil Engineering calculators • Automatic, instant results on every value and unit change • USCS (Imperial) and SI (Metric) units throughout • Clear formulas and definitions for every calculator Calculator List: Absolute Pressure Brake Horsepower Bernoulli Theorem for Head Loss Bulk Modulus Buoyant Force Chezy Coefficient Chezy Velocity Compressibility External Hydrostatic Pressure Flow Rate Fluid Density with Pressure Fluid Pressure Hydraulic Radius Kinematic Viscosity Liquid Phase Diffusion Coefficient Pump Efficiency Manning Flow Velocity Mean Depth Minor Losses Net Positive Suction Head and Cavitation Specific Gas Constant Specific Gravity with Water Weight Specific Gravity with Water Weight Loss Specific Volume Thrust Block Water Horsepower Acoustic Flow Meter Bazin's Weir Flow Broad Crested Weir Curb Capture Flow Rate Curb Gutter Flow Rate French Drain Seepage Rate Gutter Capture Efficiency Gutter Carryover Gutter Interception Capacity Rectangular Weir Rectangular Weir Discharge - Francis Equation Orifice Flow Rate Parshall Flume Flow Rate Permeameter Porous Medium Flow Rate Unconfined Aquifer Well Flow Rate V notch Weir Venturi Meter for Flow Rate Hazen Williams - Fluid Flow Rate Hazen Williams - Mean Fluid Velocity Aluminum Pipe - Pressure Rating Buried Corrugated Metal Pipe Thrust - Cross Sectional Area Buried Corrugated Metal Pipe Thrust - Pipe Wall Buried Corrugated Metal Pipe Thrust - Pressure Ductile Iron Pipe - Pressure Ductile Iron Pipe - Wall Thickness Pipe Vacuum Pressure Load Pipe Water Buoyancy Factor Plastic Pipe - AWWA C900 Pressure Class Plastic Pipe - Inside Diameter Controlled Plastic Pipe - Outside Diameter Controlled Plastic Pipe - Outside Diameter Controlled Short Term Strength Plastic Pipe - Short Term Pressure Rating Slotted Pipe Gutter Interception Smooth Wall Steel Pipe - Pressure Rating Soil Load Per Linear Length of Pipe Restrained Anchored Pipe Stress Pipe Soil Weight Pressure Unrestrained Pipe Length Change Poiseuille's Law Stokes Law Cauchy Number Cavitation Number Eckert Number Euler Number Fourier Number Froude Number Knudsen Number Lewis Number Mach Number Prandtl Number Reynolds Number Schmidt Number Sherwood Number Nusselt Number Peclet Number Strouhal Number Threshold Odor Number Weber Number Darcy Weisbach - Head Loss Darcy's Law - Flow Rate Darcy's Law - Flux Darcy's Law - Hydraulic Gradient Darcy's Law - Porosity Darcy's Law - Saturated Soil Darcy's Law - Seepage Velocity Darcy's Law - Seepage Velocity and Porosity Darcy's Law - Void Ratio Water Hammer - Maximum Surge Pressure for a Fluid Water Hammer - Maximum Surge Pressure for Water Water Hammer - Maximum Surge Pressure Head Water Hammer - Pressure Increase
