Description
Technical field the present invention relates to a kind of vertical boiler, and particularly a kind of is the method for the vertical boiler and the co-producing plant powder of fuel with plant debris.
The present boiler major part of background technology is a fuel with coal, can produce a large amount of SO during coal burning
2, H
2S, CO, CO
2Gas pollutes air, SO
2, H
2S becomes sulfuric acid etc. after running into water, big especially to the pollution of environment, SO in the most serious in the world atmosphere pollution atmosphere that burning causes from fossil energy
2, H
2Therefore S, adopts the substitute of coal to be used for boiler heat supplying, is an important means that reduces atmosphere pollution.
Carbonized rice husks is mainly used in effect such as molten steel covering and insulation in steel plant's steelmaking process, also can be used for the effect that organic fertilizer factory carries out additive.With the charring rice husk is base-material, with flyash, expanded graphite etc. is filler, it is reasonable, in light weight for shape for the rounded grain heat preserving agent for liquid steel of making, be not tied up with, free from environmental pollution, spreadability good, high insulating effect, Grcular particles of insulating agent for molten steel that cost is low.But rice husk ash production steel mill floss collecting agent for temperature isolation.Charring rice husk is through the graininess meal of a kind of black flash of control burning back acquisition in the charred rice husk stove.Owing to have good endothermic character and insulation characterisitic, use as the domestic and international large-scale popularization of the insulation material of insulation in ironmaking and the steel industry and resistive connection slag aspect.Can be widely used in grey cast-iron, ball-type cast iron, the slag-collecting thermal-insulating in the various ferrous material castings such as cast steel covers.The method of producing carbonized rice husks, rice husk ash at present is very simple and crude, generally digs a hole into the earth, and adds the fire in a stove before fuel is added and lights, and piles up husk again, makes husk smoldering under anaerobic environment, and environmental pollution is big, and heat energy can not be fully used, the waste resource.
Summary of the invention purpose of the present invention is exactly at the deficiencies in the prior art, providing a kind of is the method for the vertical boiler and the co-producing plant powder of fuel with plant debris, make full use of the heat energy that the husk burning produces when producing carbonized rice husks, rice husk ash, provide hot water and steam, simultaneously the method for co-producing plant powder.
