Page: CHP´s with combustion engine
different types of engines: • For smaller plants (< 30 kWel) gasOttoengines are used. These have shorter live time, but lower investment costs. • In the region of 30150 kWel ignition streak aggregates are used. In principal, this are diesel engines. To produce a save mixture, 710 ...

Page: CHP´s with fuel cells
Fuel cells have a high electrical efficiency and low pollutant emissions, comparatively. Because of low number of units they are very expensive. They are working in base of oxyhydrogen reaction: !fuel cell reaction.jpg! By use of a reformer biogas is transformed into hydrogenrich gas. In the fuel ...

Page: Conditioning
Divers variants of usage expects divers complex pretreatments and conditionings of biogas. Minimum of conditioning is drying and desulfurization. Condensing out the containing moisture happens by cooling the gas. Together with the condensate most of the contamination is retired. For the use of biogas as compensational natural gas ...

Page: Conditioning for feeding into natural gas mains
Basic condition for feeding into natural gas mains is, that biogas regarding specific parameters have to be compatible with natural gas. If there are wide variations, a gas mixer is arranged. Such plants are controlled by caloric value or Wobbe value, variables are pressure, natural gas volume ...

Page: Desulfurization
H 2 S would be oxidized to sulfur dioxide during combustion. This would conduct to corrosion of the engine and other parts made of metal, which are contaminated with gas. Afterwards there are three desulfurization variants, which are used generally. • Biological oxidation: introducing of 35 ...

Page: Further conditioning for usage in fuel cells
use in fuel cells interrupting spoors have to be removed. They can be removed by complex procedures by oxidizing or reducing by catalyzers. For usage in polymer electrolyte membrane fuel cells (PEMFC) the biogas is reconditioned by a reformer to pure hydrogen, finally. At usage of solid oxide ...

Page: Possibilities of application
Directly combustion to produce heat is no longer common because of the low efficiency. Conversion into electricity by combined heat and power units by use of combustion engines (common form) or fuel cells (in development) conveys a essential higher energy efficiency, because of using ...
