► Waste to Energy (Synthesis Gas-Biomass) Power Plant
Waste-to-Eergy (WtE) or energy-from-waste (EfW) is the process of generating energy in the form of electricity and/or heat from the primary treatment of waste. WtE is a form of energy recovery. Most WtE processes produce electricity and/or heat directly through combustion, or produce a combustible fuel commodity, such as synthetic gas fuels.
Municipal Solid Waste (MSW), including household waste, is the residual waste put into a black bin bag or wheelie bin. MSW contains a mixture of recyclable, organic, inorganic and biodegradable materials. Recyclable materials are recovered as many as possible before drying and shredding the remainder to make a Refuse Derived Fuel (RDF) for the process. The energy from waste process, transforms the RDF into a clean hydrogen-rich synthesis gas (syngas). Ettes Power 300 series engines can deal with this kind of hydrogen-rich syngas properly.
Syngas-Biomass is organic matter derived from living or recently living organisms. In the context of biomass as a resource for making energy, it most often refers to plants or plant-based materials which are not used for food or feed, and are specifically called ligocellulosic biomass. As an energy source, biomass can either be used directly via combustion to produce heat, or indirectly after converting it to various forms of biofuel.
Wood remains the largest biomass energy source today; examples include forest residues (such as dead trees, branches and tree stumps), wood chips. Besides wood, rice husk, crop stalk, straw, straw dust, coconut fabric dust and palm bunch still can be feed stock of biomass gas.
Tar is always troublemaker for biomass combusted into electricity energy, which can block and damage the turbocharger and intercooler. However, Ettes Power 300 series biomass engines has strong treatment and resistance ability against tar, and with advantages of low speed, big cylinder, big displacement and special design for syngas fuel, Ettes Power engines are the best choice for syngas/biomass power plant.
Because of their increased wavelength (nearly 20 meters at 20 Hz), achieving high output at low frequencies usually requires large drivers (subwoofers). Headphones or earbuds, have less trouble playing back those low frequencies despite their small size: by sealing your ear canal, they create a volume that acts as a pressure chamber. This phenomenon is totally different from what you hear when listening to a speaker playing in the open air. Without the cabin effect — another name for the same phenomenon — earbuds would produce hardly any bass.
