Abstract
一种带有混杂气化循环(10)的发电系统,其中将CO2再循环回气化器(12)用作气化反应物和工作流体。该发电系统包括新鲜氧源(20)、气化器、与气化器以流体连接形式安装的颗粒分离器(16)、合成气燃烧器(48)、与燃气涡轮的出口以流体连接形式安装的燃气涡轮(50)和气体压缩机系统(36),该压缩机系统放出压缩排放气流。将压缩排放气流的第一部分(34)通至气化器以控制气化器内的温度、为气化作用提供CO2和蒸汽以及减少其内对新鲜纯氧的需求。
Description
发明领域
本发明涉及一种利用再循环工作流体的混杂式气化循环,以及一种操作此类系统生成电能的方法。
发明背景
全球气候变化与温室气体例如二氧化碳(CO2)的排放之间的关系已有详尽的报导。传统的矿物燃料燃烧发电厂,例如煤粉燃烧发电厂,产生大量的CO2。因此,似乎始终存在提高这种发电厂的效率以及开发改进工艺以降低其CO2排放的动力。所开发的用以实现这些目标的主要方法之一基于在气化器中将煤气化生成合成气,该合成气在下游燃烧器中燃烧。
M.De Lallo等最近公开的论文“Evaluation of Innovative FossilCycles Incorporating CO2 Removal”论述了几种从燃煤电厂去除/分离CO2的已知方法,该论文在2000年10月8-11日在加利福尼亚的洛山矶召开的2000气化工艺会议上发表。该论文揭示当将这种CO2去除和/或分离系统用于煤粉燃烧发电厂的后端时,会降低电厂效率多达十一个百分点,相当于每吨$30的CO2去除费用。为对比起见,文中涉及的所有美元量都用2003美元表述。
例如,在传统的吹氧整体式气化组合循环(IGCC)发电厂中,一氧化碳(CO)常常经水-气变换为燃气涡轮机上游的氢气(H2)和CO2。然后经吸收和解吸或用膜将这类CO2分离和浓缩,然后压缩封存。然而,这类方法耗能、昂贵,并且由于从溶剂再生CO2以及伴随变换的能量损失,使系统效率降低。(由于氢气的低热值(LHV)比CO低,以每摩尔计,当CO变换为H2时损失15%的LHV。因而,为了补偿变换的损失,需要由气化过程生成更多的合成气。得自变换反应的低品位热补偿系统损失。)据估算,采用这种工艺的IGCC发电厂有六个百分点的效率损失,以及每吨$15的CO2去除费用。
U.S.6,269,624描述了一种使气态燃料与氧燃烧的组合循环发电方法,将燃气涡轮排放气中的部分二氧化碳再循环回燃气涡轮燃烧器。收集在再循环气中的二氧化碳从与燃气涡轮相连的气体压缩机的下游冷凝。
U.S.5,572,861披露了一种IGCC方法,将再循环的二氧化碳在一系列燃气涡轮燃烧器中用作稀释流体。将燃气涡轮排放的二氧化碳在多级压缩机中压缩,包括部分二氧化碳的级间分离,并导向冷凝单元。按照本发明,在加压气化器中伴着氧气与蒸汽的混合物使煤气化生成合成气。此方法采用非常复杂的装置,例如合成气高温压缩机。
GB1,298,434描述了一种方法,用纯氧使煤气化并使生成的气体在锅炉炉膛中与氧气一起燃烧。水蒸汽从锅炉炉膛的烟道气中冷凝,部分剩余二氧化碳再循环回气化器和锅炉去控制它们的温度,另一部分二氧化碳在多级压缩机中压缩并分多步冷却,从而形成液体二氧化碳。但是,这种循环的热效率不太高,同时基于蒸汽涡轮的兰金循环仅以较低的效率发电。
发明概述
本发明的一个目标是提供一种采用再循环工作流体的简单混杂气化循环系统和一种使用该混杂气化循环系统的方法,以高效地生成电能。
本发明的另一个目标是提供一种采用再循环工作流体的简单混杂气化循环系统和一种消除或降低二氧化碳到大气的排放的混杂气化循环系统。
为实现本发明的这些和其它目标,如附带的权利要求中所述,提供了一种新型发电装置和方法。
在一种方式中,本发明提供一种发电系统,包含:新鲜纯氧(O2)源;带有固体燃料入口和新鲜纯氧入口的气化器,其在升高的压力P1下运行将所述固体燃料转化成包含一氧化碳(CO)和氢气(H2)的合成气及包含焦化炭(char)的固体残渣;颗粒分离器,与所述气化器以流体连接的形式安装,用于分离所述气化器排放的合成气中的焦化炭颗粒;合成气燃烧器,带有新鲜纯氧入口和颗粒分离器排放的合成气的入口,用于燃烧合成气以生成包含二氧化碳(CO2)、水和过量氧的排放气;燃气涡轮,与合成气燃烧器以流体连接的形式安装,用于使排放气膨胀,从而用与燃气涡轮连接的发电机发电,并通过燃气涡轮的出口放出膨胀的排放气;蒸汽发生器,与所述燃气涡轮的出口以流体连接的形式安装,包含用以放出处理过的排放气的出口;气体压缩机系统,带有与蒸汽发生器的出口流体连接的入口和用于放出压缩的排放气流的出口,及用于将压缩排放气流的第一部分通至气化器的装置,以控制气化器的温度、为气化过程提供蒸汽以及减少对新鲜纯氧的需求。
在另一种方式中,本发明提供一种发电方法,其中该方法包含步骤:(a)从氧源供应新鲜纯氧;(b)将固体燃料和新鲜纯氧引入气化器,将所述固体燃料转化成包含一氧化碳(CO)和氢气(H2)的合成气以及包含焦化炭的固体残渣;(c)将来自气化器的合成气通至颗粒分离器,在颗粒分离器中使焦化炭与合成气分离;(d)颗粒分离器流出的合成气与新鲜纯氧在合成气燃烧器中燃烧,生成包含二氧化碳(CO2)、水和过量氧气的排放气;(e)使排放气在与合成气燃烧器以流体连接的形式安装的燃气涡轮中膨胀,用与燃气涡轮连接的发电机发电,经燃气涡轮的出口放出膨胀的排放气;(f)将来自燃气涡轮的膨胀排放气通至蒸汽发生器,经蒸汽发生器的出口放出处理过的排放气;(g)将来自蒸汽发生器的处理过的排放气引入气体压缩机系统;以及(h)将压缩排放气流的第一部分通至气化器,以控制气化器的温度、为气化过程提供CO2和蒸汽,以及减少其内对新鲜纯氧的需求。
如文中所用,术语“纯氧”应当广义地解释为包括任何由浓缩氧源生成的氧气流,浓缩氧源例如为低温空气分离器、例如分离膜或变压吸附系统的非低温空气分离器、贮氧罐或类似物。作为例子,由低温空气分离器生成的氧气流通常具有超过95%的氧浓度,由非低温空气分离器生成的氧气流通常具有约90-约95%之间的氧浓度。然而,只要由浓缩氧源生成,氧浓度略低于90%的氧气流也包含在术语纯氧的范围内。术语“新鲜”氧气是指由新鲜纯氧源供应的氧气,与再循环入系统的氧气相对。
本发明提供一种先进的混杂气化循环,将CO2再循环回气化器,用作气化反应物和工作流体。气化器优选为加压循环流化床(PCFB)气化器,通常在高达约55个大气压或更高的压力下运行,将诸如煤之类的固体燃料气化。相应地,气体压缩机系统将排放气的压力提高至优选至少与气化器的运行压力一样高的压力,该系统提供待再循环回气化器的主要包含二氧化碳及一些水和氧气的压缩气体。
在随合成气夹带的焦化炭和其它固体颗粒在颗粒分离器中分离之前,优选将气化器排放的合成气在合成气冷却器中冷却。颗粒分离器优选金属管形过滤器元件。如果需要,在将合成气通向气体燃烧器之前,可用传统方法从合成气中清除对燃气涡轮有害的其它物质。
根据本发明的发电系统优选包含用于将压缩排放气流的第二部分通至合成气燃烧器的装置,例如适宜的管线、管道及类似物。当排放气主要包含二氧化碳时,可将其用于控制合成气燃烧器内的燃烧温度,以控制从可能存在于合成气中的少量氮气生成氮氧化物(NOx)。通常,压缩排放气含一些水,这也有助于控制NOx。该气体中还含有一些过量氧气,这减少了合成气燃烧器中对新鲜纯氧的需求。
气体压缩机系统包含燃气涡轮压缩机和增压压缩机较为有利,燃气涡轮压缩机与燃气涡轮的轴连接。燃气涡轮压缩机通常将排放气压缩至适于将气体通至合成气燃烧器的压力,并且选择增压压缩机的压缩比以使其出口压力与气化器的压力相对应。
燃气涡轮压缩机为分级压缩机较为有利,其包含级间注水冷却系统以降低压缩机的电力需求以及增加压缩的排放气流的湿度。在本发明的发电循环中,注水有助于合成气燃烧器的NOx控制并增强气化器中的气化作用。
根据本发明的一种优选实施方式,将压缩排放气的第三部分从气体压缩机系统的出口导向二氧化碳冷凝段。如果该排放气被压缩至例如约55个大气压,该压力相应于气化器的运行压力,就可以简单地通过将该气体冷却至相对较高的温度例如约15℃而将排放气中的二氧化碳冷凝。因而,在本发明的组合循环中,二氧化碳冷凝段无需用于分离CO2的分离压缩机也是可以的。
为避免冰的形成,在二氧化碳的最终冷凝之前,在二氧化碳冷凝段中从排放气中分离出水。通过从排放气中分离出二氧化碳,形成主要包含纯氧的排出气流。这样,CO2冷凝段生成独立的冷凝二氧化碳流和水流,以及主要包含氧气的剩余气流。可将生成的液体CO2封存或用于多种用途。优选将主要包含纯氧的排出气流通至空气分离元件,即通至新鲜纯氧源以增强其效率。在一些应用中,将出口气流直接通至合成气燃烧器会比较有利,用于降低其中对新鲜纯氧的需求。
根据本发明的另一种优选实施方式,系统包含用于燃烧焦化炭的锅炉。在用于燃烧焦化炭的锅炉中,作为气化器的底灰收集的、以及作为飞灰从气化器下游的颗粒分离器收集的焦化炭可与纯氧燃烧用以生产蒸汽。用于燃烧焦化炭的锅炉生成过热蒸汽用以用燃气涡轮发电。用于燃烧焦化炭的锅炉为常压循环流化床(ACFB)锅炉比较有利。因此,来自加压气化器和颗粒分离器的灰流在被引入用于燃烧焦化炭的锅炉之前,必须在减压单元中减压。
根据本发明的发电系统优选包含将燃气涡轮放出的部分排放气从燃气涡轮导向用于燃烧焦化炭的锅炉的装置,这类用于传导的装置包括适宜的管线、管道和其类似物。由于排放气中的CO2和水,通向用于燃烧焦化炭的锅炉的排放气控制用于燃烧焦化炭的锅炉的运行温度。另一方面,排放气中的过量氧气减少了用于燃烧焦化炭的锅炉中对新鲜纯氧的需求。用于燃烧焦化炭的锅炉产生烟道气,该烟道气可以用涤气器或传统装置净化,用冷却器冷却至约65℃的温度并经由进气通风风扇通至气体压缩机系统。
在一些应用中,优选将燃气涡轮放出的部分排放气经热回收蒸汽发生器(HRSG)通向气体压缩机系统。取决于系统的操作模式,膨胀排放气在HRSG和用于燃烧焦化炭的锅炉之间的分配可以变化。通常任何时刻膨胀排放气仅通向HRSG和用于燃烧焦化炭的锅炉中的一个。系统也可以仅包含将膨胀排放气从燃气涡轮导向用于燃烧焦化炭的锅炉的装置或将膨胀排放气从燃气涡轮导向HRSG的装置。
附图简述
图1是表示基于本发明的混杂煤气化循环的发电厂的示意工艺流程图。
图1中以框形表示的每个组件各自都是公知的。因此,这类组件的细节此处不作详细描述。
优选实施方式的描述
图1中所例举的混杂循环发电厂10表示本发明的一种优选实施方式。该发电厂包括分气化器12,优选加压循环流化床(PCFB)气化器;合成气冷却器14和颗粒分离器16。颗粒分离器16优选多孔金属阻挡滤片。例如煤的固体燃料流18和纯氧20被引入气化器12,在此转化成合成气流22和含焦炭的固体残渣。在升高的压力下操作气化器12比较有利,通常为高达约55atm的压力,但是压力也可以低于或更高于55atm。
当进料到气化器的组分反应时,生成热的合成气。合成气主要包含一氧化碳(CO)和氢气(H2)。在PCFB气化器中,合成气垂直向上传送流化床的一些固体残渣穿过反应器进入循环旋风除尘器(未示出)。从床层淘析出并包含在合成气中的固体在旋风除尘器中收集并经浸入管(未示出)返回气化器底部的密层。热固体的循环起到热飞轮的作用,有助于促进有效的固-气化学反应。如果需要,可将沙子加入PCFB气化器12中以保持床层的总量并促进气化过程。
纯氧气流20源自氧源24,该氧源优选低温空气分离单元(ASU),将进入的空气流26转化为独立的氮气(N2)流28和氧气(O2)流30。ASU24生成分别用于加压和常压工艺的独立的高压氧气流30和近环境压力的氧气流32比较有利。在本发明的一些应用中,氧源24可以是除低温分离器之外的一些其它类型,例如基于变压吸附的分离器或膜分离。氧源也可以仅是一套从外部氧源定期地再充填的液氧罐。
优选将来自燃气涡轮压缩机36(以下描述)的包含CO2、O2和蒸汽的气流34也注入气化器12,为气化反应提供组分和控制处理温度。也可以在将来自燃气涡轮压缩机36的气流34和纯氧气流20引入气化器12之前先将其混合。气化器12的处理温度范围通常为约900℃-约1100℃,取决于燃料类型。
离开循环旋风除尘器之后,合成气通常穿过火管型合成气冷却器14,进入例如多孔金属(管形)阻挡滤片的颗粒分离器16,在此清除合成气中的颗粒物质。如果需要,合成气可在冷却气体净化步骤中进一步净化(未示出),该步骤采用涤气器或其它传统合成气净化装置。合成气净化装置的适宜类型取决于几种公知的因素,包括气化器12中采用的燃料的类型和品质。
优选将颗粒分离器16收集的飞灰流38和/或从PCFB气化器12移出的底灰流40收集到减压器42,并以输送至用于燃烧焦化炭的锅炉44,在此燃烧灰中的焦炭为蒸汽涡轮(未示出)生产蒸汽。用于燃烧焦化炭的锅炉44优选为常压循环流化床(ACFB)锅炉,但也可以是一些其它类型的锅炉,例如悬浮燃烧锅炉。
将清洁合成气流46通至气体燃烧器48,在此燃烧生成热气,该热气在燃气涡轮50中膨胀,经发电机52发电。在本发明的系统中,优选在燃气涡轮50的上游无需水-气变换和从合成气分离CO2。因而,消除了伴随这些操作的循环效率与燃气涡轮动力的损失。
合成气与空气分离单元24供应的纯氧54在气体燃烧器48中燃烧。来自燃气涡轮压缩机36的压缩气流56流进气体燃烧器48。压缩气体56包含CO2和蒸汽,这降低燃烧反应的温度并由此限制氮氧化物(NOx)的生成量。压缩气体56还包含一些氧气,这减少ASU 24对新鲜纯氧的需求。而且,燃烧室内气体量的增加提供了更高效的气体膨胀,从而在燃气涡轮50中更高效地发电。在一些应用中,也可以将来自CO2冷凝单元58(以下描述)的富O2气流(图1中未示出)通至气体燃烧器48。
来自燃气涡轮的排放气60是一种大部分的CO2与蒸汽和氧气的混合物,其中氧浓度通常约为3体积%。根据本发明,这些未使用的氧气可以用在气化器12、气体燃烧器48和用于燃烧焦化炭的锅炉44中。相应地,优选将来自燃气涡轮50的排放气流60输送至用于燃烧焦化炭的锅炉44。
在用于燃烧焦化炭的锅炉44中,以空气分离单元24中生成的纯氧流62作为主要氧化剂,将从气化器12和/或颗粒分离器16中回收并在减压器42中减压的焦炭燃烧。来自燃气涡轮50的热排放气流60为焦炭燃烧提供额外的氧气。由于其高CO2含量,排放气控制用于燃烧焦化炭的锅炉44的温度。用于燃烧焦化炭的锅炉44产生过热蒸汽较为有利,可将过热蒸汽用于驱动蒸汽涡轮(未示出)发电。
在本发明的一个优选实施方式中,操作气化器12使碳转化率对烟煤为约60%-约80%,对亚烟煤则接近95%。作为例子,当将Illinois#6用作燃料时,炭渣中将出现约20-40%的煤碳,该炭渣将在用于燃烧焦化炭的锅炉44中燃烧。需要时,也可以将附加的固体燃料流64例如煤引入用于燃烧焦化炭的锅炉44。
优选地,将石灰石、氨和/或尿素注入用于燃烧焦化炭的锅炉44中以控制二氧化硫(SO2)和NOx的生成。石灰石通常通过以硫酸钙(CaSO4)的形式捕获SO2而将其分离。另一方面,氨和/或尿素将NOx化学还原为氮气(N2)和水。优选将底灰66从用于燃烧焦化炭的锅炉44收集并从系统移至垃圾场或类似地方。
优选以设定的路线使用于燃烧焦化炭的锅炉44的排放物穿过诸如袋滤除尘室的除尘器68和冷却器70。含有一系列过滤器的袋滤除尘室68除去排放气中的大部分飞灰。在冷却器70中将排放气冷却至低温,例如约30℃。在冷却器70中,一些水被冷凝并从排放气中除去。冷却后,优选使气体在引入燃气涡轮压缩机36之前流过进气通风风扇72。
也可以将来自燃气涡轮50的排放气60,或其一部分引入热回收蒸汽发生器(HRSG)74,在其中通过从热排放气摄取热量而生成过热蒸汽以驱动蒸汽涡轮(未示出)。非必须地,可以将部分清洁合成气46通至(未示出)HRSG74,并在其内燃烧以提高排放气的能量含量。在气体冷却器76中将HRSG74的排放气最终冷却至低温,例如约30℃。在此冷却阶段,排放气中的部分水蒸气从系统移出。然后将冷排放气送至燃气涡轮压缩机36。
优选燃气涡轮压缩机36为带有通过注水78进行级间冷却的分级压缩机。注水78降低压缩动力需求并增加压缩排放气的湿度。当将压缩排放气通至气化器12和气体燃烧器48时,压缩气体蒸汽含量的提高增强了气化器12中的气化作用,并有助于控制气体燃烧器48中的NOx。
优选将包含CO2、O2和蒸汽的压缩排放气分成三部份。大部分气体被注入气体燃烧器48并在燃气涡轮50中膨胀。在将压缩排放气的剩余部分分成通入气化器12的部分和通至CO2冷凝段58的部分之前,可以将其经末端压缩机80(增压压缩机)进一步压缩。
优选将通至CO2冷凝段58的压缩气体在热交换器82中通过将热量传递给ASU24放出的冷O2流30、32进行首次冷却。在冷却器84中进一步冷却压缩气体,以从排放气中首次除去水,然后液化排放气中的CO2。由于CO2处于高压,液化CO2所需的温度就较高,例如对于57atm的压力约为16℃。CO2冷凝段58提供冷凝CO2流86,优选用泵88将其进一步加压,并经CO2管线90送去处理或进一步使用。
CO2冷凝段58之后,剩余的排放气为主要包含氧气的冷气体流92。优选将冷气体流92通至空气分离器24,以减少O2需求量、节省动力以及充当空气分离器的冷却剂。可选地,可将富O2气体92通至(未示出)气体燃烧器48,由此进一步降低其内对新鲜纯氧的需求。
存在于压缩排放气中、例如源自用于燃烧焦化炭的锅炉44的二氧化硫(SO2)可CO2冷凝段58中与CO2一起冷凝。因而,特别是当处理生成的液体CO2时,可以从本混杂气化循环中免除分离硫的俘获装置
上述发电厂虑及高效和经济地使用宽范围的较廉价煤,同时致力于解决CO2对环境的破坏作用。其优点包括能够分离CO2而无需昂贵的耗能变换、化学/物理吸附和/或脱附。例如,如与传统发电厂相对比,采用依据本发明的发电厂去除CO2的预期费用每吨低于$10,而传统发电厂的费用从煤粉发电厂的每吨$30变化到传统吹氧IGCC发电厂的每吨$15。
上述发电厂的其它优点包括(i)通过再循环排放气中所含的过量氧使整体耗氧量最小化;(ii)免除了传统IGCC发电厂中为支撑水变换反应所需的大量蒸汽需求;以及(iii)通过使CO2可在气体压缩机的排放压力下使用,或通过完全消除对传统IGCC发电厂中通常采用的用于CO2分离的分离压缩机的需要,而降低CO2分离压缩机的动力需求。
因而,根据本发明的发电厂将提供一种用于发电的系统,该系统带有用于消除燃煤电厂的CO2排放的更简单、更可靠及廉价的装置;并且将大大降低伴随从排放气去除CO2并将其加工以传送至封存地的传统工艺而来的发电厂效率的损失。
以上例子是对本发明优选实施方式的举例说明。然而,如本领域普通技术人员所能理解的,取决于发电厂的需要,上述本发明的许多方面,例如气化器和焦炭子系统,可以采用其它的形式。而且,尽管组件的上述排布是目前优选的配置,但是显然取决于各种设计考虑,该系统的各种组件可以重新排布和/或以相互间不同的组合来使用。
