Diki biomass steam jenareta yakaderera nitrogen

2. Hurongwa hweshanduko chaiyo:
(1) Wedzera mhepo yechipiri. Kuti uwane kudzika kwakadzika uye kwegiredhi kupisa kwemhepo yevira, nzvimbo yakakura yekupisa uye nzvimbo yekudzoreredza inosara. Imwe yechipiri mhepo muromo inomiswa pane imwe neimwe yemakona mana echoto chechoto (inogona kusvetuka kumusoro uye pasi, uye mhepo yechipiri inoiswa munzvimbo yepamusoro kuti ive nechokwadi chekureba kwekupora). Iyo yechipiri mhepo duct yakashongedzerwa ine inotsvedza gonhi. Iwo echipiri emhepo nozzles ane zvisimbiso. Shanduko yemhepo yechipiri ndiyo nzira huru yekudzora mafuta-mhando uye thermal-mhando NOx.
(2) Dzima mhepo yechitatu. Iyo tertiary air nozzle yakavharwa, uye yekutanga tertiary air pombi inoshongedzerwa neinoparadzanisa. Mushure mokupfuura nemhepo yakapatsanurwa negobvu uye yakatetepa, rutivi rwakakora runopinda mumhepo yepamusoro yechipiri, uye rutivi rwechiedza runoshandiswa semhepo yechipiri. Kuunza mhepo yepamusoro mumhepo yechipiri kunogona kuderedza yechipiri mhepo vhoriyamu yepakutanga main burner range. Uye zvakare, chikamu chemarasha akapwanyika mumhepo yepamusoro anogona kutumirwa muchoto chemoto nguva isati yasvika (ichienzaniswa neyepakutanga chinzvimbo chepamusoro), nekuti Kudzikiswa kwechinzvimbo kwakaenzana nekurebesa nguva yekupisa kwemarasha akapwanyika muchoto. mumhepo yepamusoro, iyo inobatsira kudzikisa zvirimo zvenhunzi zvinopisa zvinopisa mumhepo inopisa.
(3) Shanduko yeyechipiri mhepo nozzle. Maererano nechirongwa chakananga chekuchinja kwechipiri chemhepo yemhepo denderedzwa muchoto, sezvinoratidzwa mumufananidzo 1, nzvimbo nhatu dzine maitiro akasiyana zvachose emunda uye kugoverwa kwenzvimbo yepedyo-yemadziro inoumbwa pachikamu chemuviri wechoto. Inogona kuve nechokwadi kuti kune okisijeni yakakwana pamadziro kudzivirira slagging uye yakakwirira-yekushisa corrosion pasina kushandura nzira yejeti huru.

Iyi nzira yekupisa inogona kuvandudza kupenya kweiyo yekutanga mhepo yakanyungudutswa marasha kuyerera muchoto uye kuichengeta kure nemadziro emvura pazasi, ichideredza slagging, kupisa-kupisa kwepamusoro uye kuiswa kwedota muchoto. Pamusoro pezvo, nekuti kwakanangana nekutanga uye kwechipiri mhepo tangent madenderedzwa kwakapesana, chinongedzo chemarasha akapwanyika nemhepo chinononoka, nekudaro kuderedza kuburitsa kweNOx. Mukuwedzera, iyo yechipiri mhepo inoiswa tangentially, kuitira kuti iyo yekutanga mhepo inoyerera ichidzokera kumashure ichimhanya mumhepo inotonhora kubva kumusoro, kuitira kuti marasha akaputsika anonyungudika munzvimbo ino. Pasi pemamiriro ekushayikwa kweokisijeni, nyaya inoputika inoputika nokukurumidza sezvinobvira uye inopisa uye inopisa, iyo inonyanya kukosha pakupisa kwakagadzikana uye kupisa. Pane zvikomborero.
(4) Kugadziriswa kwe micro-oil ignition. Kune madiki majenareta eutsi, tsiva 2 zvinopisa muchikamu chepasi cheiyo yepakutanga gwenya jenareta ine yakaderera NOX inopisa ine micro-oiri ignition basa. Chigadzirwa chacho chinogona kuita kuti marasha akapwanyika atungidze nekupisa nekukurumidza. Mushure mekushandura, hazvidikanwi kushandisa pfuti huru yemafuta kana jenereta yemhepo iri kushanda, iyo inochengetedza mafuta akawanda emagetsi emagetsi.
