Wood Chip Gas /Wood Gas /Syngas /Biomass Gas Electricity Generator
- 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.
- 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.
- 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). 300 series engines can deal with this kind of hydrogen-rich syngas properly.

Gas Generator Technical Features
Syngas-biomass is far different with methane base gas (natural gas, biogas and Coalmine gas etc). Syngas is much more tricky, it is in low heat value, high in tar content and unstable in gas quality (TAR always cause problems of pipeline-blocking, cylinder-pollution and spark plug-jamming etc). So, based on syngas as fuel, it is a headache in fields of gas engines all over the world, there are few engine can't be fired by syngas properly. However, Ettes 300 series low speed engines can work with syngas smoothly. The key reasons are that they have unique and remarkable features & advantages as follows:
- Cylinders Structure in Line & Upright & Concise Layout, which means simple, easy and low cost in operation & maintenance. Engine-Overhaul can be handled at user's site.
- Large cylinder (300mm), long stroke, low speed and big displacement 215L and 242L, which means big reserve power capacity and constant power output.
- Low engine speed at 500 or 600rpm, which means high reliability for continuous operation, sufficient combustion, low exhaust gas temperature and high heat efficiency.
- Naturally aspirated (no turbocharger and Intercooler), which means low failure rate and minimum downtime (TAR in syngas always block and damage turbocharger and intercooler).
- Internal mixing system (for high hydrogen gas over 15%), gas and air intake separately, then mixed in combustion room, which means no risk of backfire and cylinder knocking.
- Strong treatment and resistance ability against TAR, long term trouble free operation. TAR always raises problems of pipeline-blocking, cylinder-pollution and spark plug-jamming etc.
- Compressed Air Starting System, smooth starting, high success rate and easy for maintenance.
- Open Cooling System, adopting plate-type heat exchanger, high efficiency and easy for scale-removal.
- Dismountable intake-valve-box, which means can clean TAR easily and conveniently (no need disassembling of cylinder head).
- Low-speed engine makes the noise lower. The maximum noise ≤100dB. Through silencer, the noise will be ≤70dB.
- Low speed means low components wearing, namely lower cost in spare parts replacement and long life span.
- Long Overhaul Time of 60,000 hours and lifecycle of 20-25 years, which ensure sustainable financial rewards of power plant.
Applicable Low BTU Fuel of Syngas Engines
- Biomass from MSW, Woodchips, Sawdust, Straw, Rice husks, Nut-shells, and Chicken manure etc.
