To make a healthy business case for a digester, the efficient conversion of organic dry matter into biogas is not the only condition. Valuation of the biogas produced must also be done optimally in order to arrive at a good business case. If there is a local heat demand that is greater than or equal to biogas production, converting to heat is the most efficient route (other options include applying a CHP or upgrading the biogas to green gas).
Special biogas burners are needed to burn this biogas (gas with> 50% methane). There are currently several suppliers on the market that supply biogas burners, but the requirements that these suppliers place on the biogas are quite high. For example, the biogas must have a very low dew point and the H2S concentrations must also be very low. Upgrading the biogas to these specifications costs energy, which reduces the efficiency of the total installation.
To counteract this loss of efficiency (and thereby increase the economic feasibility of biogas projects) we started looking for an efficient biogas burner that imposes less “strict” requirements on the biogas and is therefore more efficient. We have found this biogas burner in the biogas burners from Thermigas.
