Kunzwisisa uye Kugadzirisa Njodzi dzeKupisa Marasha

Ichi chinyorwa chinopa mhedziso yakazara ye marasha anopfungaira, kuongorora zvimiro zvayo, mashandisirwo, uye njodzi dzakabatana kwezvakatipoteredza nekuchengetedza. Isu tinoongorora maitiro anosanganisirwa mukushandiswa kwayo, tichiongorora zvakanakisa maitiro ekudzikisa kukanganisa kwakashata uye kuve nechokwadi chekubata zvine hunyanzvi. Dzidza nezvemhando dzakasiyana dze marasha anopfungaira, maitiro avo, uye nzira yekusarudza mhando yakakodzera kune chaiwo maapplication. Isu tinokurukura zvakare kutevedza kwemitemo uye kufambira mberi kwazvino mukuderedza kutsika kwezvakatipoteredza marasha anopfungaira kushandiswa.

Chii chinonzi Steaming Coal?

Kupisa marasha, inozivikanwawo semarasha ekupisa, imhando yemarasha anonyanya kushandiswa kugadzira magetsi mumagetsi ekupisa. Iyo inoratidzwa neiyo yakakwira simba remukati uye yakaderera sarufa yemukati, ichiita kuti ive yakakodzera kupisa mumaboilers. Maitiro acho anosanganisira kupisa marasha kuti abudise kupisa, izvo zvinobva zvaburitsa chipfunga chekutyaira maturbine uye kugadzira magetsi. Sarudzo yezvakakodzera marasha anopfungaira kwakakosha pakuita kwakaringana magetsi chirimwa uye kuderedzwa kwehutsi.

Mhando dzeMarasha Anopisa

Mhando dzinoverengeka dzemarasha dzinorongwa se marasha anopfungaira, chimwe nechimwe chine zvinhu zvakasiyana-siyana. Misiyano iyi inokonzeresa kukodzera kwadzo kune zvirimwa zvemagetsi zvakasiyana uye maapplication. Hunhu hwakakosha hunosanganisira chinzvimbo (semuenzaniso, bituminous, sub-bituminous, lignite), inoshanduka nyaya yemukati, madota, uye sarufa.

Bituminous Coal

Bituminous marasha rudzi rwakajairika rwe marasha anopfungaira, inoratidzirwa nehuwandu hwemagetsi ayo uye hunyoro hushoma. Inopisa zviri nyore uye zvakanaka, zvichiita kuti ive sarudzo yakakurumbira yekugadzira magetsi makuru. Nekudaro, inogona zvakare kuve nepamusoro sarufa yemukati kana ichienzaniswa nemamwe marudzi, ichida mamwe matanho ekudzora emission.

Sub-bituminous Coal

Sub-bituminous marasha ane simba rakaderera pane bituminous marasha asi kazhinji ane yakaderera sarufa. Izvi zvinoita kuti ive imwe nzira yakakodzera mumatunhu ane mirau yakaomesesa yekuburitsa. Yayo yakaderera calorific kukosha ingangoda kugadziridzwa kune boiler dhizaini uye maitiro ekushanda.

Lignite Coal

Lignite marasha, anozivikanwawo semarasha ebrown, ane simba rakaderera pakati pe marasha anopfungaira mhando. Hunyoro hwayo hwepamusoro hunoda kugadziridzwa mukubata uye maitiro ekupisa. Nepo kazhinji isingadhure, kushanda kwayo kwakaderera uye kuburitsa kwakakwira kunopa kune yakakura kukanganisa kwezvakatipoteredza.

Mamiriro Ezvakatipoteredza uye Chengetedzo Yekufunga

Kupisa kwe marasha anopfungaira inoburitsa magasi egreenhouse, anosanganisira carbon dioxide (CO2), achikonzera kushanduka kwemamiriro ekunze. Zvimwe zvinosvibisa zvakaburitswa zvinosanganisira sulfur oxides (SOx), nitrogen oxides (NOx), particulate matter (PM), uye mercury. Izvi zvinobuda zvinogona kuita zvakakosha pamhando yemhepo uye hutano hwevanhu. Kubata kwakanaka uye kuchengetedza kwe marasha anopfungaira zvakakoshawo kudzivirira njodzi dzakadai sekuputika kweguruva nemoto.

Kuderedza Kukanganisa Kwezvakatipoteredza

Tekinoroji uye maitiro akasiyana-siyana anoshandiswa kuderedza kukanganiswa kwezvakatipoteredza marasha anopfungaira kushandiswa. Izvi zvinosanganisira:

• Flue gasi desulfurization (FGD) kubvisa SOx
• Selective catalytic reduction (SCR) kuderedza NOx
• Matunhu ekudzora zvinhu (semuenzaniso, electrostatic precipitators, machira mafirita)
• Carbon kutora uye kuchengetedza (CCS) matekinoroji
• Maitiro ekupisa akavandudzwa ekuwedzera kugona

Regulatory Compliance uye Best Maitiro

Mitemo yakasimba inotonga kushandiswa uye kubata kwe marasha anopfungaira kuchengetedza zvakatipoteredza uye hutano hwevanhu. Vashandi vemagetsi emagetsi vanofanirwa kutevedzera iyi mirau, kazhinji inosanganisira emission yekutarisa, kushuma, uye zvinodiwa zvemvumo. Kuomerera kumitemo yekuchengetedza kwakakosha kudzivirira tsaona uye kuona kugara zvakanaka kwevashandi nenharaunda yakapoteredza.

Kusarudza Yakakodzera Kupfungaira Marasha

Sarudzo yezvakakodzera marasha anopfungaira kune chirimwa chemagetsi chinosanganisira kunyatsoongorora zvinhu zvakati wandei, zvinosanganisira:

Kunyatsotariswa kwezvinhu izvi kunopa kugadzirwa kwemagetsi kwakakwana uye kunoderedza kukanganisa kwezvakatipoteredza. Bvunza nenyanzvi dzeindasitiri uye masangano anodzora kuti uve nechokwadi chekutevedzwa uye maitiro akanaka.

Kuti uwane rumwe ruzivo nezvemhinduro dzesimba, funga kuongorora mamwe manyuko emagetsi. Inner Mongolia Xinxin Silicon Industry Co., Ltd yakazvipira kupa zvigadziriso zvitsva zveramangwana rakachena resimba.

¹ Dhata pamusoro pezvivakwa zvemarasha inogona kuwanikwa mune dzakasiyana siyana geological ongororo uye indasitiri zvinyorwa. Ndokumbira utarise kunobva kwakakodzera kune chaiyo data zvinodiwa.
