Description

Multi-nozzle coal water slurry or powder coal gasification furnace and industrial application thereof

Technical field

The present invention relates to a kind of vapourizing furnace that is used for coal water slurry or coal gasification, relate to a kind of multi-nozzle vapourizing furnace.

Background technology

The cleaning of coal and efficient utilization are the great technical tasks in the energy and environment protection field, the world today, also are one of gordian techniquies of Chinese national economy sustainable development.Gasification is the main path that primary energy source is changed into clean secondary energy, and its product is fuel gas (coal gas), synthetic gas, reducing gas, hydrogen, carbon monoxide.The coal gasification technology has obtained using widely in the production of combined cycle (IGCC) power generation assembly, synthetic ammonia and synthesizing methanol industry, producing acetic acid by carbonylation method and aceticanhydride industry, sponge iron, the preparation of pure carbon monoxide, the fields such as preparation of pure hydrogen, and vapourizing furnace then is the key equipment of gasification.For this reason, numerous scientific and technical personnel study, have developed various types of vapourizing furnaces.At present, in the technology that adopts air flow bed (fluid injected bed, carry bed) to gasify, representationally mainly contain two kinds: adopting coal water slurry is that the vapourizing furnace of raw material has Texaco's (Texaco now is a GE company); Employing fine coal is that the vapourizing furnace of raw material has Xie Er (Shell).Document U.S.Pat.Nos.4,637,823,4,527,997,5,281,243 disclose Texaco gasifier respectively, and the geometric properties of this vapourizing furnace is nozzle axis and coal gas and melt cinder outlet dead in line, and the both is on the vapourizing furnace main body axis.In view of this vapourizing furnace is an air flow bed, thereby cause partial material (stream thigh) short circuit.Applicant's experiment test shows, if material mean residence time in such vapourizing furnace is 5 seconds, in fact, wherein the partial material residence time is less than outside 1 second stove of promptly overflowing, another part material in stove the residence time considerably beyond 5 seconds.That is to say that the residence time of material in this vapourizing furnace is a very wide distribution, have 50%～60% material just to overflow outside the stove less than mean residence time.The efficiency of carbon conversion of Texaco gasifier is generally less than 95%, and steam resolution ratio is also less than 20%; Document U.S.92-960345 discloses the Xie Er vapourizing furnace.Coal gas and melt cinder are reversed flow, and promptly coal gas makes progress, and melt cinder is downward.Its shortcoming has two, one, and melt cinder is followed because of no heating gas, very easily solidifies and stops up slag notch; Its two, the tiny cinder that is suspended in the coal gas stream will pass through the longer pipe road, and the change flow direction, just can enter upstream device and carry out waste heat recovery or gas solid separation, pipeline and upstream device stop up easily, the both can shorten the operational cycle.Defective in view of above two kinds of type of furnaces, Chinese patent 98110601.3 discloses a kind of multi-nozzle opposed type coal water slurry or pulverized coal gasification furnace, this coal slurry gasifier has carried out pilot plant (22 tons/day) and demonstration unit (1150 tons/day) operation, this vapourizing furnace efficiency of carbon conversion is more than 98%, and is higher 3 percentage points than Texaco stove; This powder coal gasification furnace carries out pilot scale (15～45 tons of coal/skies) operation, and efficiency of carbon conversion consumes, shown extraordinary gasification performance than every technic indexs such as coal consumptions than oxygen more than 98%.Facts have proved, this vapourizing furnace also leaves some room for improvement, present vapourizing furnace can't satisfy modern production enterprise to handling the demand of 3000 tons of above scale Coal Gasification Technology of coal day, and the homogeneity of the temperature distribution in the stove and the processing power of vapourizing furnace also can further improve.

Summary of the invention
