ʻO ka corrosion haʻahaʻa haʻahaʻa ka sulfur dioxide a me ka sulfur trioxide i hana ʻia e ka sulfur i ka wahie i ka wā o ka hoʻopau ʻana i ka cylinder, ʻo ia mau mea ʻelua he kinoea, e hui pū me ka wai e hoʻohua i ka waikawa hyposulfuric a me ka sulfuric acid (ke piʻi ka mahana o ka paia cylinder. haʻahaʻa ma mua o ko lākou wahi hau), a laila e hana ʻia ai ka ʻino haʻahaʻa haʻahaʻa. .

Ke haʻahaʻa loa ka helu kumu o ka ʻaila cylinder, e ʻike ʻia nā waihona e like me ka pena ma ka ʻili o ka liner cylinder ma waena o kēlā me kēia wahi hoʻoheheʻe aila, a e pōʻeleʻele ka ʻili o ka liner cylinder ma lalo o ka mea like me ka pena. . Ke hoʻohana ʻia nā liner cylinder chrome-plated, e ʻike ʻia nā kiko keʻokeʻo (chromium sulfate) i nā wahi i ʻino.

ʻO nā mea e hoʻopilikia ai i ka ʻino haʻahaʻa haʻahaʻa, ʻo ia ka sulfur ma loko o ka aila wahie, ka waiwai alkali a me ka helu ʻana o ka aila i loko o ka ʻaila cylinder, a me ka ʻike wai o ke kinoea scavenging. ʻO ka maʻamau o ka ea scavenging e pili ana i ka haʻahaʻa o ka ea a me ka mahana o ka ea scavenging.

Ke holo ka moku i kahi kai haʻahaʻa kiʻekiʻe, e nānā pono i ka hoʻokuʻu ʻana o ka wai condensed o ka ea.

ʻO ka hoʻonohonoho ʻana o ka mahana pumping he duality. Hiki i ka ha'aha'a ha'aha'a ke pā'ani i ke 'ano o ka "ho'olu'u malo'o", e emi ana ka ha'aha'a o ka ea scavenging, a e pi'i ka mana o ka mīkini nui; akā naʻe, e hoʻopilikia ka wela o ka ea scavenging haʻahaʻa i ka mahana o ka paia cylinder. Ke emi ka mahana o ka paia cylinder ma mua o ka hau, e hiki mai ka corrosion haʻahaʻa i ka wā ʻaʻole lawa ka waiwai kumu o ka kiʻi ʻaila cylinder ma ka paia cylinder.

Ua ʻōlelo ʻia i loko o ka pōʻaiapuni lawelawe ʻenehana nui i ka wā e holo ana ka mīkini nui i ka haʻahaʻa haʻahaʻa, pono ia e hoʻonui i ka mahana scavenging e pale i ka corrosion haʻahaʻa haʻahaʻa.

No ka hoʻonui ʻana i ka mahana o ka wai hoʻoheheʻe wai e hoʻemi i ka wela haʻahaʻa, ua hoʻohana ʻo MAN i ka ʻōnaehana LCDL no ka hoʻonui ʻana i ka wai hoʻoluʻu ʻenekini nui a hiki i 120 °C e pale ai i ka corrosion haʻahaʻa haʻahaʻa.
