    摘要： Internal combustion engines tolerant to tar-containing producer gas are disclosed. Two concepts are described. The engines are tolerant to producer gas from a biomass gasifier with minimal pretreatment. When biomass is gasified to be burned for power generation or to be used to synthesize chemicals such as biofuels, a large fraction of the installation cost is spent on equipment to clean up the heavy organic components (also referred to as ‘tars’) from the gas stream, hereafter referred to as ‘producer gas’. The invention described herein may be used to enable power generation from gasified biomass with minimal treatment. It may also be used to treat biomass at a very low cost for other uses such as synthesizing chemicals. The producer gas is not necessarily limited to biomass derived. Producer gas derived from coal or other sources has similar issues and the invention described herein would be equally applicable.

    摘要： A biomass gasification power generation system including: a gas generation device that generates a combustible gas from a biomass and a gasification agent; an internal combustion engine that generates motive power from a fuel gas containing the combustible gas generated by the gas generation device; and a generator that generates electric power from the motive power generated by the internal combustion engine. The power generation system is additionally provided with a water electrolysis device that generates oxygen and hydrogen through the electrolysis of water. The gasification agent contains oxygen generated by the water electrolysis device, and the fuel gas contains hydrogen generated by the water electrolysis device. The oxygen concentration in the gasification agent is from 22 vol. % to 40 vol. %.

    摘要： A combined heat and power plant includes a gasifier, a heat exchanger arranged to reduce the temperature of the raw synthesis gas formed in the gasifier by exchanging the heat of the raw synthesis gas into heating medium used for heating and forming cooled raw synthesis gas, a filtration unit for cleaning the cooled raw synthesis gas to form refined synthesis gas suitable as a fuel for an internal combustion engine, an internal combustion engine where the refined synthesis gas is burnt to produce mechanical power, ducts for connecting different parts of the plant to each other a raw gas burner arranged after the gasifier to burn the raw synthesis gas formed in the gasifier during the time when the refined synthesis gas is not utilized in the internal combustion engine. A method for treating raw synthesis gas a combined heat and power plant is also disclosed.

    摘要： The invention relates to an environmentally friendly motor vehicle based on the use of energy-accumulating substances (EAS) and can be used not only in transportation engineering, but also in power engineering to produce electric power with the aid of thermal engines run on hydrogen that is produced from aluminum composites in reaction with water.The object of the invention is to provide an environmentally friendly motor vehicle powered by hydrogen that is produced from EAS, comprising a closed water supply system to supply a reactor of a hydrogen generator with water obtained by condensing water vapors from exhaust gases, and quick change cartridges composed of a cylinder casing and a cover with hydrogen-generating elements in the form of plates of aluminum composites mounted inside the casing.The object is attained in the following way. A motor vehicle comprising an internal combustion engine provided with a liquid cooling system with a primary radiator mounted in front of the engine, and a hydrogen generator accommodated in a trunk and operating on the reaction of aluminum composites with water, further comprises an exhaust gas cooling system to autonomously supply the generator with water by condensing water vapors in exhaust gases. The exhaust gas cooling system is connected to an exhaust manifold of the engine and consists of an expander, a condenser in the form of a gas/air heat exchanger and a storage tank for collecting water condensate and discharging uncondensed gases. The storage tank is connected by means of conduits to the hydrogen generator, wherein the supply of water to the latter and circulation of water in order to intensify the hydrogen release process are performed by a pump mounted inside the storage tank, and drainage of water from the generator into the storage tank is performed through a filter mounted in the generator housing.
