Riello Biogas Burners

IF THE OPERATING CONDITIONS ARE DIFFERENT FROM THE ABOVE, PLEASE ASK FOR A SUPPORT, AS VARIATIONS OF THE BIOGAS CHARACTERISTICS COULD AFFECT THE BURNER SIZING AND RELATED ACCESSORIES. COMPOSITION VALUE NOTE Fuel Dry dehydrated biogas Methane content (CH 4 ) 65% minimum Please referrer to the RIELLO’s Application Engineers for combustion of Biogas with Methane content (CH4) lower than 65% (i.e. 50%-55%); the feasibility is highly dependent from the particularity of the application and must be properly assessed. Carbon Dioxide content (CO2 ) 35% maximum Hydrogen Sulfide content (H2S) < 0,1% Maximum percentage content in dry volume. A H2S content higher than 0,1% requires the use of special gas valves. Relative humidity < 60% Dew point < -10°C PCI 6.46 kWh/Nm 3 It is acceptable a difference in the chemical composition as to lead to a variability of maximum 5% of the calorific value. RS and DB Series | Burners for BIOGAS combustion BIOGAS BURNERS GENERAL REQUIREMENTS In order to support our customers and with the aim of providing a quick response to various needs of information, here below is shown a quick guide to the basic characteristics that can allow the access of a standard solution for Biogas combustion. THE BIOCHEMICAL CHARACTERISTICS OF BIOGAS CAN HAVE A HIGH VARIABILITY, DEPENDING ON VARIOUS REASONS RELATED TO HIS PRODUCTION; BASED ON THAT, RIELLO CAN PROVIDE DIFFERENT SOLUTIONS FOR DIFFERENT NEEDS. For the GAS TRAIN selection please referrer to the RIELLO’s Engineers, they will be pleased to support the selection process in function of BIOGAS characteristics and available pressure. 12
