Fixed bed gasification of corn stover biomass fuel: Egypt as a case study

摘要

Abstract > This paper focuses on the optimal performance of a small tri‐generation power, heat, and cooling plant, which uses corn stover as the feedstock. First, 100 kg?h ?1 of the corn stover is converted into syngas by the gasification process, using a downdraft fixed‐bed reactor at gasification temperatures reaching 995?°C and with an oxidant–fuel ratio of 1.65. About 243.18 kg?h ?1 of product gas mass flow with 4.766?MJ?kg ?1 of calorific value is supplied to an externally fired gas turbine (EFGT) to convert this fuel to electrical power. It is estimated that the EFGT is capable of producing 70.57?kW of electrical power with a high‐temperature heat exchanger efficiency of 75% and a pressure ratio of 4.84 at a turbine inlet temperature of 875?°C. The absorption refrigeration system is used for the cooling process. The cooling power type="mathematics"> ( ? <sub> eva </sub> ) of the absorption cooling system is 130.92?kW with a cooling tower temperature of 15?°C and a system performance coefficient (PC) of 0.6. The recovered heat flow to the generator ( type="mathematics"> ? <sub> gen </sub> ) and the refrigerating heat flow are 82.62 type="mathematics"> kW <sub>th</sub> and 48.83 type="mathematics"> kW <sub>ref</sub> , respectively, with a circulation ratio of 4.07. For the whole system (gasifier, EFGT, and absorption cooling), the gross electrical efficiency (ηnetEL ) is 21.78% and the net thermal efficiency ( type="mathematics"> η <sub>th</sub> ) is 47.43% with a system cooling‐to‐power ratio (CPR) of 1.88. The simulation of this system was conducted using Cycle‐Tempo software. ? 2019 Society of Chemical Industry and John Wiley & Sons, Ltd </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract Type =“Main”XML：Lang =“en”> <标题类型=“main”>抽象</ title> > 本文侧重于小型三代电力，热量和冷却厂的最佳性能，用于使用玉米秸秆作为原料。首先，100公斤？H. ？1 </ sup> 通过气化过程将玉米秸秆转化为合成气，在气化温度下达到995Ω°C，氧化剂 - 燃料比为1.65。大约243.18千克？？1 </ sup> 产品气体质量流量4.766？MJ？kg ？1 </ sup> 热值供应到外部烧制的燃气轮机（EFGT）以将该燃料转换为电力。据估计，EFGT能够在875Ω·℃的涡轮机入口温度下产生75％的高温热交换器效率，高温热交换器效率为75％，压力比为4.84。吸收制冷系统用于冷却过程。冷却功率 type =“mathematics”> （？</ i> <sub> eva </ i> </ sub> 的） </ span> 吸收冷却系统的吸收冷却系统为130.92Ω·kW，冷却塔温度为15Ω°C和0.6的系统性能系数（PC）。将回收的热流流到发电机（ type =“mathematics”> ？</ i> <sub> gen </ i> </ sub> 的） </ span> 而制冷热流为82.62 type =“mathematics”> kw. <sub> th </ sub> </ span> 和48.83 type =“mathematics”> kw. <sub> ref </ sub> </ span> 分别具有4.07的循环比例。对于整个系统（气化器，EFGT和吸收冷却），总电效率（ηnetEL）为21.78％，净热效率（ type =“mathematics”> η. <sub> th </ sub> </ span> ）47.43％，系统冷却到功率比（CPR）为1.88。使用Cycle-Tempo软件进行该系统的仿真。还2019年化学工业协会和约翰瓦利＆amp; SONS，LTD. </ p> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-16091/'>《Biofuels, bioproducts & biorefining: Biofpr》</a> <b style="margin: 0 2px;">|</b><span>2020年第1期</span><b style="margin: 0 2px;">|</b><span>共13页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li > <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span><a href="https://www.zhangqiaokeyan.com/clc/180.html" title="生物工程学（生物技术）">生物工程学（生物技术）;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=tri‐generation&option=203" rel="nofollow">tri‐generation;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=gasification&option=203" rel="nofollow">gasification;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=EFGT&option=203" rel="nofollow">EFGT;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=absorption cooling system&option=203" rel="nofollow">absorption cooling system;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=biomass&option=203" rel="nofollow">biomass;</a> </p> <div class="translation"> 机译：三代;气化;efgt;吸收冷却系统;生物量; </div> </li> </ul> </div> </div> <div class="literature cardcommon"> <div class="similarity "> <h3 class="all_title" id="enpatent66">相似文献</h3> <div class="similaritytab clearfix"> <ul> <li class="active" >外文文献</li> <li >中文文献</li> <li >专利</li> </ul> </div> <div class="similarity_details"> <ul > <li> <div> <b>1. </b><a class="enjiyixqcontent" href="/journal-foreign-detail/0704022070369.html">Fixed bed gasification of corn stover biomass fuel: Egypt as a case study</a> <b>[J]</b> . <span> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=&option=202" target="_blank" rel="nofollow" class="tuijian_auth tuijian_authcolor"> </a> <a href="/journal-foreign-16091/" target="_blank" rel="nofollow" class="tuijian_authcolor">Biofuels, bioproducts & biorefining: Biofpr .</a> <span>2020</span><span>,第1期</span> </span> </div> <p class="zwjiyix translation" style="max-width: initial;height: auto;word-break: break-all;white-space: initial;text-overflow: initial;overflow: initial;"> <span>机译：玉米秸秆生物量燃料的固定床气化：埃及为例</span> </p> </li> <li> <div> <b>2. </b><a class="enjiyixqcontent" href="/journal-foreign-detail/070406210704.html">The impact of fuel properties on the emissions from the combustion of biomass and other solid fuels in a fixed bed domestic stove</a> <b>[J]</b> . <span> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Mitchell E.
