SDEC, is a joint venture of Cummins and DFAC, which is established in 1996 with a registered capital number of 100 million USD.? SDEC is capable of producing over 235000 engines every year? SDEC mainly focuses on B, C, L series of diesel engines?? CCEC is also a joint venture of Cummins and Chinese company.? the main products of CCEC are N, K, M series with the power range of 145?1343KW?Pressure Regulator:?To regulate the pressure of the gas supplier and make sure stable gas pressure.Pressure Meter:?To show and monitor the gas pressure within the normal range?Anti-explosion Valve:?To release the pressure in case the mixed gas is ignited in the intake manifold. In this way, the generator will be well protected from ignition resulted from mistaken adjustment of advance angle of ignition?Flame arrester:?This part is designed to prevent the fire entering the gas tank from the engine. As natural gas and biogas are highly flammable gas, the back-fire is highly dangerous to the gas source. So it is very important to have this flame arrester.?? 60KW Cummins biogas generatorThis Cummins biogas generator is currently working in a salt mine factory. The associated gas coming out of the salt well contains a certain amount of methane around 60%. This is good enough for our biogas generator.With the paralleling system, the electricity generated is supplier to local utility grid.?1. What is the gas production of your biogas project per day or per hour? ? ?The production depends on the scale of your biogas project. Please consult your biogas project engineer for more details. Many people would ask me:" Hi Kevin, I have 1000 cattle here, how much biogas can be produced and how much kw generator I need?" To be honest, it is not easy give a certain figure because the production of the biogas will be influenced by many factors such as the technology of fermentation, the temperature of the anaerobic digester, and the raw materials for the biogas. So it is better to ask for advice from the biogas project engineer.?2. Has the biogas been pretreated?As the Hydrogen sulfide?H?S?and moisture in new biogas are harmful to the biogas generator set, they should be cleaned out with the following facilities before it enters the biogas generator.?3. What is the biogas pressure?The gas pressure should be 3-100 KPa to supply enough biogas for the biogas generator. If the pressure is lower than 3KPa a booster fan is necessary to increase the gas pressure.?4. What is the methane (CH4) percentage of the biogas?The methane (CH4) should be at least 55% to keep the biogas generator running normally. The higher of the methane percentage, the better it will be for the generator. If the methane is less than 55%, the power of the biogas generator will not reach the power defined.5. What is the gas consumption of our biogas generator?The gas consumption rate is 0.65 m?/KWH if the methane percentage is no less than 55%.Let's take a 50kw biogas generator as an example, it will use around 33 cubic meters of biogas every hour, namely 792 cubic meters every day. ?
