Kuki amashanyarazi agomba gutekwa mbere yo gutangira? Nubuhe buryo bwo guteka amashyiga?

Guteka amashyiga nubundi buryo bugomba gukorwa mbere yuko ibikoresho bishya bitangira gukoreshwa. Muguteka, umwanda n'ingese bisigaye mu ngoma ya generator ya gaze mugihe cyo gukora birashobora gukurwaho, bigatuma ubwiza bwamazi hamwe nisuku yamazi mugihe abayikoresha babikoresheje. Uburyo bwo guteka amashanyarazi ya gaze nuburyo bukurikira:

(1) Uburyo bwo guteka
1. Kuzamura umuriro muke mu itanura hanyuma uteke buhoro buhoro amazi mumasafuriya. Imyuka yabyaye irashobora gusohoka binyuze mumashanyarazi cyangwa hejuru yumutekano.
2. Hindura ifungura ryokongoka hamwe na valve yumuyaga (cyangwa valve yumutekano). Gumana ibyuka kumuvuduko wakazi 25% (6-12h ukurikije umwuka wa 5% -10%). Niba ifuru yatetse icyarimwe mugice cya nyuma cyitanura, igihe cyo guteka kirashobora kugabanuka muburyo bukwiye.
3. Kugabanya ingufu zumuriro, gabanya umuvuduko winkono kuri 0.1MPa, kura umwanda buri gihe, no kuzuza amazi cyangwa kongeramo imiti itarangiye.
4.
5. Noneho gabanya ingufu zumuriro kugirango ugabanye umuvuduko, ukureho imyanda yimyanda umwe umwe, kandi wuzuze amazi.
6. Kuzamura umuvuduko uri mu nkono kugera kuri 75% yumuvuduko wakazi kandi ukomeze 5% -10% byuka mumasaha 6-20.

Mugihe cyo guteka, amazi yamazi agomba kugenzurwa kurwego rwo hejuru. Iyo urwego rwamazi rugabanutse, amazi agomba kuzuzwa mugihe. Kugirango hamenyekane neza ko amashyiga akora neza, amazi yinkono agomba gutondekwa mu ngoma zo hejuru no hepfo hamwe n’imyanda isohora imyanda ya buri mutwe buri masaha 3-4, kandi hagomba gusesengurwa alkaline na fosifate y’amazi y’inkono. Niba itandukaniro ari rinini, imiyoboro irashobora gukoreshwa Kora ibyo uhindura. Niba ubunyobwa bwamazi yinkono buri munsi ya 1mmol / L, hagomba kongerwaho imiti yinyongera.

(2) Ibipimo byo gutanura amashyiga
Iyo ibirimo fosifate ya trisodium bikunda kuba bihamye, bivuze ko reaction yimiti iri hagati yimiti iri mumazi yinkono hamwe ningese, igipimo, nibindi hejuru yimbere yimbere yabirangije byarangiye, kandi guteka birashobora kurangira.
Nyuma yo guteka, kuzimya umuriro usigaye mu itanura, kura amazi yinkono nyuma yo gukonja, hanyuma usukure imbere mumashanyarazi usukuye namazi meza. Birakenewe gukumira igisubizo kinini cya alkalineite gisigaye muri boiler gutera ifuro mumazi yabotsa kandi bikagira ingaruka kumiterere ya parike nyuma yo guteka. Nyuma yo gukubura, inkuta zimbere yingoma numutwe bigomba kugenzurwa kugirango bikureho umwanda. By'umwihariko, imiyoboro y'amazi hamwe n'ipima ry'amazi bigomba kugenzurwa neza kugirango birinde imyanda ituruka mugihe cyo guteka.
Nyuma yo gutsinda ubugenzuzi, ongera wongere amazi mumasafuriya hanyuma uzamure umuriro kugirango ushire mubikorwa bisanzwe.

(3) Kwirinda mugihe utetse amashyiga
1. Ntibyemewe kongeramo ibiyobyabwenge bikomeye muri boiler. Mugihe utegura cyangwa wongeyeho ibisubizo byibiyobyabwenge kuri boiler, uyikoresha agomba kwambara ibikoresho birinda.
2. Kubotsa hamwe na superheater, amazi ya alkaline agomba kubuzwa kwinjira muri superheater;
3. Igikorwa cyo kuzamura umuriro no kuzamura igitutu mugihe cyo guteka kigomba gukurikiza amabwiriza atandukanye hamwe nuburyo bukurikirana mugihe cyo kuzamura umuriro no kuzamura ingufu mugihe icyotezo gikora (nko guhanagura igipimo cyamazi, gukaza umwobo nu mwobo wamaboko imigozi, n'ibindi).
