燃气轮机燃料气计量调压系统

  燃气(qi)(qi)轮(lun)机燃料(liao)气(qi)(qi)计量(liang)调压(ya)(ya)系(xi)统是天然气(qi)(qi)长输管道压(ya)(ya)气(qi)(qi)站内为燃气(qi)(qi)轮(lun)机供(gong)气(qi)(qi)的橇装系(xi)统(装置(zhi)),集(ji)过滤、加热、调压(ya)(ya)、计量(liang)、放空、放散、泄(xie)露(lu)报警、自动切换等功(gong)能于一(yi)体的燃气(qi)(qi)计量(liang)调压(ya)(ya)系(xi)统。本系(xi)统具(ju)有防(fang)爆要(yao)求高(gao)、用气(qi)(qi)压(ya)(ya)力(li)调节范围大、安全性(xing)能好、连(lian)续稳定供(gong)气(qi)(qi)等特(te)点。

       燃气(qi)轮机燃料气(qi)计(ji)量(liang)(liang)调(diao)(diao)(diao)压(ya)(ya)系(xi)统(tong)(tong)(tong)(tong)(tong)一般由过滤加热系(xi)统(tong)(tong)(tong)(tong)(tong)、计(ji)量(liang)(liang)系(xi)统(tong)(tong)(tong)(tong)(tong)、调(diao)(diao)(diao)压(ya)(ya)系(xi)统(tong)(tong)(tong)(tong)(tong)、放(fang)(fang)空(kong)(kong)系(xi)统(tong)(tong)(tong)(tong)(tong)、燃气(qi)泄(xie)露报警系(xi)统(tong)(tong)(tong)(tong)(tong)等几(ji)个子系(xi)统(tong)(tong)(tong)(tong)(tong)组成。其中(zhong)调(diao)(diao)(diao)压(ya)(ya)系(xi)统(tong)(tong)(tong)(tong)(tong)具有“压(ya)(ya)力控制系(xi)统(tong)(tong)(tong)(tong)(tong)”的配(pei)置特点,采用了“安(an)全(quan)紧急切断(duan)阀(fa)+监(jian)控调(diao)(diao)(diao)压(ya)(ya)阀(fa)+自力式调(diao)(diao)(diao)压(ya)(ya)阀(fa)”的配(pei)置方式;计(ji)量(liang)(liang)系(xi)统(tong)(tong)(tong)(tong)(tong)则(ze)需配(pei)套流量(liang)(liang)计(ji)算机进(jin)行(xing)气(qi)体的温(wen)压(ya)(ya)补(bu)偿(chang)以便进(jin)行(xing)流量(liang)(liang)计(ji)算。放(fang)(fang)空(kong)(kong)系(xi)统(tong)(tong)(tong)(tong)(tong)原(yuan)则(ze)上采用集中(zhong)放(fang)(fang)空(kong)(kong),燃气(qi)泄(xie)露报警系(xi)统(tong)(tong)(tong)(tong)(tong)则(ze)可以和主(zhu)阀(fa)门及放(fang)(fang)空(kong)(kong)系(xi)统(tong)(tong)(tong)(tong)(tong)连(lian)锁,当现场(chang)发生(sheng)泄(xie)露危险时,由站控系(xi)统(tong)(tong)(tong)(tong)(tong)指挥主(zhu)阀(fa)门关闭(bi),并打开(kai)放(fang)(fang)空(kong)(kong)系(xi)统(tong)(tong)(tong)(tong)(tong)进(jin)行(xing)紧急放(fang)(fang)空(kong)(kong)。

 

       本系统对调(diao)(diao)(diao)(diao)压(ya)阀(fa)的(de)要求(qiu)(qiu)很高,首先要求(qiu)(qiu)其快速开(kai)启能(neng)力,同时调(diao)(diao)(diao)(diao)压(ya)阀(fa)的(de)反应速度快(比如有的(de)场合配(pei)套了加(jia)速指挥器),具备(bei)这种特点的(de)调(diao)(diao)(diao)(diao)压(ya)阀(fa)中以轴流(liu)式调(diao)(diao)(diao)(diao)压(ya)阀(fa)应用比较普遍。

  系统特(te)点:

  a、采用轴(zhou)流(liu)式调(diao)压阀,具有大流(liu)量时压力稳定、关(guan)闭性能优(you)等(deng)特点;

  b、调(diao)压精度高±1%、调(diao)节比宽;

  c、等百分比特性(对数特性);

  d、系统安全(quan)切(qie)断反(fan)应时(shi)间小于1S;

  e、系统还(hai)可配(pei)置自动切断、阀位远传、阀位指示(shi)(就(jiu)地和远程)、等功能(neng);

  f、气(qi)体的加(jia)热一般采用电加(jia)热方式,分(fen)为直接(jie)式电加(jia)热器(炉)和间接(jie)式电加(jia)热器(炉)。

  典型业绩实例:西气东输及扩建工程等著名管线压气站(燃气轮机用气)、靖边压气站燃气轮机燃料气计量调压系统。
