Siemens presented its new high-efficiency, low-emission gas engines at the 6th China International Bioenergy and Biomass Utilization Summit in Shanghai. One of the advantages of these new engines is that they can use a wide range of fuels to generate electricity and heat. They can be powered by natural gas, biogas, gas from landfills or sewage treatment plants, synthesis gas, well gas, or a wide selection of other gases, which means they can supply a wide range of industrial sectors.
Siemens is developing these engines in its new Power and Gas division business, Siemens Engine Business, which aims to resolve and overcome many of the obstacles currently affecting industry. Together with Siemens’ heavy investment in R&D and the experience it has gained over more than 50 years, this makes Siemens Engine Business a leading international technology provider in both liquid and gas fuel engines for a wide range of applications and sectors.
Standing out among its products, high-efficiency, low-emission gas engines can be used in several applications such as cogeneration, electricity generation, and waste-based energy. These engines use the latest fuel injection and supercharging technologies, which boost their power, reduce their fuel consumption, and optimize their maintenance costs.
The SEB factory in Zumaia (Guipuzcoa) has spent more than 50 years designing and manufacturing high-performance engines in Spain that are exported the world over, largely to countries such as Argentina, the United States, Egypt, Morocco, Turkey, Pakistan, Singapore, Malaysia, Australia and, of course, all over Europe. The power ratings of the SEB portfolio range from 150 to 2065 kW for gas engines/generators.
One of the company’s most important research and development facilities is in Miñano, in the Spanish Basque Country. The company has developed a new technology, Siemens Fuel Blending solution, at this facility that allows an engine run on 100% biogas, 100% natural gas or a blend of both. This system enables engines to run even when the primary fuel is not available because they can change from biogas to natural gas at the press of a button. An automatic change to 100% biogas takes place as soon as the engine reaches nominal speed.
This dynamic fuel blending system is especially designed for use in situations with biogas restrictions; fuel can be switched 100% in such a way that the engine’s operability is not affected. One of the main advantages of Siemens engine flexibility is that it provides a safe, efficient and reliable power supply system even when the fuel supply is interrupted.
