SCR系统成为新一代柴油机“标配”

近日,国内新型船用环保柴油机(产品库 求购 供应)研制佳音频传。

8月18日,沪东重机有限公司交验了国内首台带高压选择性催化还原(SCR)系统的低速柴油机,完全满足国际海事组织(IMO)体育外围氮氧化物(NOx)排放控制技术章程三级标准(Tier Ⅲ)的限值要求。8月22日,中国船舶(股票体育外围)重工集团柴油机有限公司交验了全球首套满足Tier Ⅲ排放标准、带低压SCR系统的低速柴油机。

在IMO减排标准要求下,经济适用的SCR系统几乎成为新一代柴油机的“标配”。作为“后起之秀”,中国柴油机制造企业奋起直追,“打包”提供了系列带自主研发SCR系统的主机(产品库 求购 供应体育外围)产品,力争扩大市场份额。

IMO Tier I 及Tier Ⅱ标准全球适用,Tier Ⅲ仅限于排放控制区,该区域外的海域则按照Tier Ⅱ标准执行。日趋严格的氮氧化物排放标准对船用发动机(产品库 求购 供应体育外围)的研制提出了更高要求,节能、环保、高效成为柴油机动力创新的方向。

至于双燃料发动机方案,其缺点是受船型限制,目前只在少数LNG船上使用,且双燃料主机价格是普通发动机的两倍及以上,使用成本过高。
