Description
Technical field
The present invention relates to bio-energy equipment, specifically is a kind of biomass gasifying furnace.
Background technology
The main energy sources component of biomass is that organic volatile divides and fixed carbon, biomass produce materials such as inflammable gas, tar and residual carbon simultaneously in heat-processed, with the production combustion gas be the gasifying biomass of purpose to want as much as possible exactly be combustion gas with Wood Adhesives from Biomass, few generation does not even produce tar and residual carbon.Organic volatile divides at 300-500 ℃ just can begin gasification, generation combustion gas and tar, so biomass at first burned be the organic volatile branch.
Existing oxidation style biomass gasifying furnace is short and thick body of heater, adopts general air as vaporized chemical, and gasification is the one-part form reaction, relies on a part of biomass in vaporizer and air combustion, to provide gasification required temperature condition.Because it is the easiest to be burned that the organic volatile in the biomass divides, will make quite a few volatile matter that is converted into fuel gas product that gasifies easily burn earlier like this, cause the final combustible gas scale of construction that generates to reduce; Stay a large amount of residual carbon behind the gasifying biomass and can not be converted into combustion gas, discharge from furnace bottom, cause the waste of biomass energy and become lime-ash.
Summary of the invention
The invention provides a kind of biomass gasifying furnace, can increase the output that gasifying biomass is converted into combustion gas, improve the gasification efficiency of biomass gasifying furnace.
The invention provides a kind of biomass gasifying furnace, comprise the body of heater shell and be fixed in the furnace body support of body of heater shell, be provided with stove layer outer wall in the described body of heater shell, be provided with stove layer inwall in the described stove layer outer wall, the gasification layer is heated in forming in the described stove layer inwall, form the outer gasification layer that is heated between stove layer outer wall and the described stove layer inwall, the bottom of described stove layer inwall is communicated with the burning heating zone that described stove layer outer wall bottom forms, and described stove layer outer wall bottom is provided with whipping appts, steam entry and oxygen-enriched inlet.
Biomass gasifying furnace of the present invention can make biomass be heated in described to gasify in the gasification layer dropping process, the gasification layer that is heated outside the volatile matter of the easy gasification of the overwhelming majority and small-particle biomass are upwards transferred to after the interior gasification layer gasification of being heated at once continues to gasify, can prevent that a large amount of volatile matters of gasification easily from burning earlier, make the final combustion gas output that generates increase, improve gasification efficiency; Water vapor and the residual carbon reaction that enters from steam entry generates inflammable gas in addition, can make full use of the remaining residual carbon in burning back with respect to prior art, avoids the waste of biomass energy, further increases the output of combustion gas.
