BIOGAS¦ free passage makes it resistant to foreign objects, and its solid construction makes it resistant even to abrasive materials. EnergyJet provides the only dry to fully homogeneous mixing system on the market that can handle energy crops with ease, and with an integrated cutting system. It makes using screw conveyors, mixing pits, and tanks a thing of the past with its ability to mix and feed the digester in a single step. Systems can be automated for 24-hour feeding or manual feeding, depending on the customer’s specific needs. EnergyJet combines the advantages of both dry and liquid solid matter feeding into a single machine.
Caterpillar G3520C Biogas Gen Set
The first commercial shipment of the next generation G3520C biogas generator set rated at 2000 electric kilowatts (ekW) happened in October 2013 via Cat dealer Carolina Cat to owner Enerdyne Power Systems. This Cat G3520C biogas generator set converts biogas fuel into useful electricity and heat. The electricity can be exported to the local electric utility as a qualified renewable resource or consumed locally. Caterpillar has launched an engineering update to the Cat G3520C biogas-fueled generator set for operation at 60Hz—primarily in North and South America—that increases power output from 1600 to 2000 ekW via new controls, gear train, base frame and

cooling system design. Over the past seven years, the model G3520C gas generator set has become a popular selection for landfill, wastewater, and agricultural biogas applications across the globe. Until now, the G3520C was limited in biogas applications to engine speeds of 1200 rpm. By increasing engine speeds to 1,500 rpm, and updating the cooling system, baseframe and controls, Caterpillar was able to increase power output by 25 percent with a nominal change in footprint while maintaining the same owning and operating costs.
Primary Flow Signal Digester, Bio-Gas (HVT-DG) flow metering system
The HVT-DG flow metering system is a customizable, insertable Venturi meter engineered to deliver accurate and reliable measurement of low or irregular pressure, and dirty, wet gas environments. This meter is suitable for measuring any type of gas, including digester gas generated in municipal wastewater treatment facilities in the normal processing of sewage, and a wide variety of biogas applications. The HVT-DG meter is available in a standard configuration, as well as special configurations designed for any
