The invention discloses a powdery active coke fluidized bed desulfurization, ammonia injection and denitration combined system and method. The method includes the steps: 1) enabling dedusted flue gasto flow into a fluidized bed desulfurization tower and contact with sulfur-containing active coke and catalyzed powdery active coke, and removing sulfur dioxide in the flue gas by adsorption; 2) enabling the desulfurized flue gas after gas-solid separation to enter a fluidized bed denitration tower, adding ammonia and the powdery active coke, enabling powdery active coke to catalyze the ammonia toreduce nitric oxide in the flue gas into nitrogen, and removing the nitric oxide; (3) separating the flue gas after denitration by the aid of a second gas-solid separator and a bag-type dust collector, conveying the separated flue gas into a chimney, recycling the sulfur-containing coke separated by a first gas-solid separator into the fluidized bed desulfurization tower to be circularly used, and recycling circulating coke separated by a second gas-solid separator into the fluidized bed desulfurization tower to be circularly used, and adding the catalyzed powdery active coke separated by thebag-type dust collector into the fluidized bed desulfurization tower to perform desulfurization.

The invention relates to a device and craft for using fluidized bed to burn kerogen. The raw oil and kerogen are transmitted into the boiler combustion device through the transmission system. The device includes fluidized bed boiler, vortex separator, and ash particle combustion system and ash dredge reclaiming device. In the boiler, the hot wind enters with small aperture speed and hot fluidized speed through the directional cap, the wind is divided into the first wind and the secondary wind; the wind quantity can be adjusted, maintains the stability of the bed and homogeneity of temperature, the temperature is maintained between 850deg.C-920deg.C. The smoke is separated through the separator, the raw particle returns into the furnace to be burned, the residue tail gas reclaims heat through several heat exchangers, and the ash dredge in the furnace is discharged out of the dredge colder with high wind quantity and pressure through the electric dust eliminator, which can be used as cement mixing material. The combustion intensity and efficiency are high, the contamination is little.

The invention relates to manufacture of garbage incinerator, and in particular relates to a whirlwind suction garbage incinerator which has the advantage of rapidness, environmental friendliness and energy conservation. The garbage incinerator comprises a furnace structure, a chassis structure and a furnace cushion structure and is characterized in that the furnace structure is a whole furnace body which is cylindrical, a center steel tube is arranged in a hearth, and the centre steel tube is vertically installed and communicated with a chimney; the top of the hearth, the bottom of the hearthand a bent tube part are connected with an exhaust pipe which is communicated with the outside of the furnace body, the periphery of the lower part of the furnace body is provided with a plurality offans, and the inlet air pipe of each fan extends into the hearth so as to form a rotary airflow forming assembly on the chassis structure; the chassis structure part in the hearth is provided with a cavity with an upward hydraucone, the hearth of the furnace cushion structure is provided with one segment of cavity with an upward hydraucone, and two segments of cavities with downward hydraucones are positioned above; and the upper part of the furnace body is provided with at least two feed inlets. The garbage incinerator provided by the invention has the advantages of rapidness, environmental friendliness, energy conservation and lower cost.

The invention provides a combustion furnace. The combustion furnace is used for coal combustion, generated smoke is changed into sludge fertilizer, clean gas is discharged to the environment, the fog hazard degree is lowered, and high chimneys do not need to be constructed. Smoke and gas which are generated after coal combustion are subjected to two times of shower water spraying and one time of chemical agent processing under the effect of closed system terminal electric fan pumping and is discharged into the atmosphere after being purified, and sludge formed after the smoke is subjected to shower water spraying and precipitates can be used as the fertilizer. The combustion furnace can be used for coal combustion for heating of north residents, coal combustion in plants in all places, coal combustion in brickyards in all places, and the like.

The invention discloses a removing device and a removing method for particulate pollutants generated by combustion of biomass fuel. The removing device comprises a chimney, a wet-type electric dust remover, a smoke condenser, a wet-type ash remover, a spiral ash remover, a combustion chamber and a heating furnace shell. The wet-type electric dust remover is arranged in the chimney. The smoke condenser sleeves the chimney. The wet-type ash remover is arranged at the lower end of the chimney. The smoke condenser is connected with the upper end of the spiral ash remover. The combustion chamber and the spiral ash remover are arranged in the heating furnace shell. A feed port communicated with the inside and the outside of the heating furnace shell is arranged on the combustion chamber. Smoke contains a large quantity of steam after the biomass fuel combusts, the steam can be condensed to form a thin water film on the surface of a precipitation pole when the temperature of the smoke continues dropping, and a cooling water jacket is arranged on the outer portion of the precipitation pole, so that exhaust smoke temperature is reduced, and heat of the smoke is recycled; condensed water generated by condensation serves as a water source of the wet-type electric dust remover, so that a water adding device, a water spraying device and the like are omitted, and water pollution is reduced.
