摘要

In the biomass power plant for use of regenerating raw materials such as wood, predried wood pieces (1) arrives over biomass stocks (2) and a subsequent biomass lock (3) provided with electrical vibrators in the biogas developers (4), in which the burn of the biomass and the development of hot biogas take place, which is led via a dynamic drying gas cleaner (6) and a wood gas distillate separator (7) into a converter with combustion engine, and over a device technology, a steam generator for the production of regulating stream is driven. In the biomass power plant for use of regenerating raw materials such as wood, predried wood pieces (1) arrives over biomass stocks (2) and a subsequent biomass lock (3) provided with electrical vibrators in the biogas developers (4), in which the burn of the biomass and the development of hot biogas take place, which is led via a dynamic drying gas cleaner (6) and a wood gas distillate separator (7) into a converter with combustion engine, and over a device technology, a steam generator for the production of regulating stream is driven. A fresh air is supplied to the biogas developer via a spraying chamber-air dryer, is cooled by cooling water with 3[deg]C and is dried. In the biogas developers, a carbonization gas developing in the dynamic drying gas cleaner is cleaned by adhering suspension particles, in which drop bolls ionized from a cartridge, consisting of 50% pumice grains and 50% heat-resistant plastic drop into the gas stream and there an adhering of the sulfur particle present in the gas stream causes on the drop balls. The drop balls fall down then into a funnel-like lower part provided with guide plates on a filter, by which dust particles fall through and the drop balls over a deionizer and a collecting- and transport equipment in deionizing condition, led back again into the cartridge, in which the drop bolls are ionized again over ionization bars for the continuation of the process. The cleaned biogas is led first over a glass fiber roll filter and afterwards into the wood gas distillate separator. At a radiator bars, projecting into the lower part of the wood gas distillate separator, a condensate forms, which is regularly exhausted and the biogas then led by a cartridge consisting grid meshes, The cartridge is fastened with ceramic rings. The temperature of the radiator staffs (bar) is controlled via a sensor and an automatic controller. Rotational energy developing in the converter with combustion engine is supplied to the steam generator and there the regulating stream is produced, which is fed into a place or fed into public net. A part of regulating stream is used for the heating of water in the hot water tank and for clad water-cooling of the converter over a heat exchanger and again used in the biomass predryer over mixer and circulation pumps for heating purposes.
