The contents of the paper Introduction Biogas utilization in Poland Biogas potential in Upper Silesia region Examples of utilization: Żywiec, Ostrowiec Świętokrzyski

Introduction: 

Introduction Biogas: flammable gas, which is produced as a result of methane fermentation, thanks to activity of methane bacteria. Organic compounds are changed into biogas and inorganic compounds in an oxygen-free environment.

Introduction: 

Introduction Conditions that favor methane fermentation: temp. ca. 30 – 35 OC (mesophile f.) neutral or slightly alkaline reaction (pH 7.0 – 7.5) period of detaining the substrate 12 – 36 days (mesophile f.) lack of light and oxygen

Introduction: 

Introduction Biogas is a mixture of the following compounds: CH4: 40 – 85% (typical 55 – 65 %) CO2 O2, H2S, N2, other: andlt; 5 % Typical calorific value: 5.5 – 6.5 kWh/m3 (19.8 – 23.3 MJ/m3)

Introduction: 

Introduction Typical biogas utilization: as fuel for boilers (heat production) as fuel for combustion engines (electric energy production, if heat recovery is performed also heat production) after CO2 separation, gas can be pressed into a gas grid (used in the same way as natural gas)

Introduction: 

Introduction Three main ways of biogas production: at sewage treatment plants: fermentation of sludge at waste dumps: a natural process which accompanies waste storage at agricultural farms: fermentation of animal and vegetable waste

Biogas utilization in Poland:

Biogas utilization in Poland Biogas from waste dumps: andgt; 32 objects andgt; 16.0 MWel andgt; 7.1 MWth

Biogas utilization in Poland: 

Biogas utilization in Poland Biogas from agricultural farms (and from food production industry): andlt; 10 objects andlt; 5.0 MWel

Biogas potential in Upper Silesia: 

Biogas potential in Upper Silesia 2004 – 2005: determining the renewable energy resources at non-industrial areas of Upper Silesia region Silesian voivodship consist of 170 communes, 22 communes (the biggest cities) have been excluded from the project

Biogas potential in Upper Silesia: 

Biogas potential in Upper Silesia Orderer was: The Board of Silesian Voivodship The project has been realized by: Polish Academy of Sciences, Mineral and Energy Economy Research Institute, Kraków The project has been financed by: The Voivodship Fund for Environmental Protection and Water Management in Katowice

Biogas potential in Upper Silesia: 

Biogas potential in Upper Silesia Theoretical and technical potential of biogas: Theoretical potential has been assumed as maximum possible for gaining amount of power and energy from a certain source and certain area with total collecting the substance which is the source of biogas and with assuming lossless conversion of chemical energy into other effective forms of energy.

Biogas potential in Upper Silesia: 

Biogas potential in Upper Silesia Theoretical and technical potential of biogas: Technical potential has been assumed as maximum possible for gaining amount of power and energy from a certain source and certain area with such collecting the substance which is the source of biogas which is possible in reality and with assuming efficiency of conversion of chemical energy into other effective forms of energy according to available devices.
