Biobil® Version 2.4
Program for the detailed calculation of mass and energy balances of heating plants. Multi-stage boilers and multi-stage heat recovery systems (including condensation and air preheating units) are considered.Based on MS-Excel and VBA
The results are presented in tables for subsequent processing and in a clearly arranged flow sheet.

Input parameters:
- Composition of the fuel (direct input or comprehensive data base available).
- Water content of the fuel.
- Gross calorific value (direct input, calculation, and comprehensive data base available).
- Contents of unburned carbon and CO2 in the ashes (comprehensive data base available).
- S und Cl in the ashes.
- Oxygen content in the flue gas (input as O2-content, CO2-content or air ratio λ).
- CO- und NOx-content in the flue gas.
- Amount of fuel used or capacity of the boiler (in kW) – alternative input.
- Temperatures of the flue gas in the different boiler sections.
- Flue gas temperatures in the different stages of the condensation unit.
- Ambient temperature and pressure.
- Side constraints for flue gas recirculation (flue gas recirculation ratio or determination of the maximum adiabatic flue gas temperature).
- Parameters to calculate a quench process (optional).
- Data in order to determine the heat losses of the heating plant
Output parameters:
- Composition of the fuel (dry base and wet base)
- Combustion air used (in mol/kg fuel (w.b.), kg/kg fuel (w.b.), Nm3/kg fuel (w.b.), m3/kg fuel (w.b.), mol/h, kg/h, Nm3/h und m3/h).
- Composition of the flue gas in the different plant units.
- Amount of the flue gas in the different plant units (in mol/kg fuel (w.b.), kg/kg fuel (w.b.), Nm3/kg fuel (w.b.), m3/kg fuel (w.b.), mol/h, kg/h, Nm3/h und m3/h).
- Density of the flue gas at different temperatures.
- Amount of condensate produced.
- Contents of flue dust in the flue gas.
- Visualisation of all relevant energy fluxes of the plant.
- Specific parameters (adiabatic flue gas temperature, dew point of the flue gas, direct and indirect efficiencies with and without condensation unit)
- Amount of ashes produced.
- Presentation in a clearly arranged flow sheet
Fields of application:
- Design of heating plants: calculation of the flue gas streams in all different plant sections, of the fuel used, of the amount of ashes produced, etc.
- Evaluation of the performance of combustion plants: calculation of the heat produced and the average efficiencies (over a given evaluation period).
- Calculation also for alternative fuels possible (e.g. pyrolysis gas, natural gas, heating oil).
