Farmyard manure gas fermenter - with program controlled recirculation of floats and sinks layers

摘要

A farmyard manure gas fermenter is a horizontal cylinder, made of steel, plastic, concrete, wood or combinations of them. One side wall has pipes for the gas extraction, for the supply of fresh manure and the pump connections for the sinks and floats layers. The opposite side wall has pipes for the outflow of the digested manure, for a recirculation and for the removal of extreme floats or sinks layers. This creates a plant which can be produced at a capital cost which equals the savings of fuel oil by the gas produced. It requires little maintenance.
