Description
Technical field
The present invention relates to a kind of from tar removing formula biomass fixed-bed gasification furnace system.
Background technology
Biomass are very important renewable energy sources, have the features such as recyclability, low contaminative and extensive distributivity.Utilize the biomass energy as an alternative, to low-carbon emission reduction, reduce " Greenhouse effect " and improve atmosphere acid rain environment tool being of great significance.Biomass gasification system utilizes biomass airtight anoxia burning in vapourizing furnace exactly, by producing inflammable gas after carbonization and thermochemistry oxidation.
Fixed-bed gasification furnace is the important kind of biomass gasification system.In fixed-bed gasification furnace, fuel exists with the state of piling up in stove, completes gasification in the mode of grate firing.Fixed-bed gasification furnace is because the fuel thermal decomposition time is longer, and binder is more, so the coal-tar middle oil content of combustion gas is higher, adds that produced fuel gas temperature is lower, causes tar very easily to be separated out, thereby stops up gas pipeline.
At present gasifying biomass furnace system adopts outside tar removing as washing etc., or by increasing by two, tertiary air improves biological fuel gas temperature and solves or alleviate tar problem.
For example, Chinese patent application 201010251310.2 discloses a kind of scale fixed bed biomass gasification power generation production technology and suite of equipment, it is made up of four parts: (1) raw material pretreatment portion, mainly comprises raw material collection, oven dry and formation system; (2) gasifying biomass part, is mainly macro-organism matter fixed-bed gasification furnace and relevant auxiliary facility thereof; (3) gas sweetening part, mainly comprises the equipment such as ash disposal, tar removing, desulfurization, dechlorination; (4) fuel gas generation part, the combustion gas after deep purifying mainly utilizes combustion power generation in oil engine.
