► What's Syngas ?

Syngas, or synthesis gas, is a fuel gas mixture consisting primarily of hydrogen, carbon monoxide, and very often some carbon dioxide. Syngas is usually a product of gasification and the main application is electricity generation. Syngas is combustible and often used as a fuel of internal combustion engines. It has less than half the energy density of natural gas.

Syngas can be produced from many sources, including natural gas, coal, biomass, or virtually any hydrocarbon feedstock, by reaction with steam (steam reforming), carbon dioxide (dry reforming) or oxygen (partial oxidation). Syngas is a crucial intermediate resource for production of hydrogen, ammonia, methanol, and synthetic hydrocarbon fuels.

Production methods include steam reforming of natural gas or liquid hydrocarbons to produce hydrogen, the gasification of coal, biomass, and in some types of waste-to-energy gasification facilities.

► Special Features & Merits of Ettes Power Syngas-Biomass Engines

Syngas is far different with methane base gas (natural gas, biogas and Coalmine gas etc). Syngas is much more tricky, it is low in heat value, high in tar content and unstable in gas quality (TAR always raise problems of pipeline-blocking, cylinder-pollution and spark plug-jamming etc).
 
So, there are few engines can be fired by syngas properly. However, Ettes 300 series low speed engines can work at syngas smoothly. The key reasons are that our 300 series engines 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 syngas with high hydrogen content over 10%), 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 can ensure sustainable financial rewards of the power plant.

► Requirements for Syngas-Biomass Quality

• Before entering into engine, the biomass should be appropriate filtering, gas-liquid separation and pressure regulation. If the temperature is too high, it should be through cooling treatment, and make sure there is no liquid content in the gas.

  Heat value≥4MJ/Nm3.
  Gas pressure 3~5kpa, Pressure change rate≤1kPa/min
• The capacity of syngas pressure-buffering tank should match well with the generator’s gas consumption.
• The acceptable fuels can be low BTU gas (including Syngas, Wast to Energy Gas, Biomass,Wood gas, producer gas, rice husk gas, sawdust gas, woodchip gas, straw gas, coal gas, coking gas, coke oven gas, semi-coke gas, synthesis gas, pyrolysis gas etc.)

► 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.
