D-Type BoilerInesigubhu esikhulu seSteam phezulu, ixhumeke ngokuqondile esigungwini samanzi esincanyana ngezansi. I-D-Type Water Tube Boiler ukunciphisa isikhathi sokujikeleza kwephrojekthi jikelele. Amasethi amabili we-180t / h ama-boilers amukele ukwakheka okujwayelekile, ukulethwa module, kanye nomhlangano osendaweni. Sinikeza ukuholwa kwezobuchwepheshe kokufakwa kwesayithi nokuthunyelwa.
1. Izici ezihlelekile ze-D-Type Boiler
I-Convection Tube Bundle kanye nesigubhu kuhlangenwe nakho okunwetshiwe. Isigaxa sokuqala seshubhu se-convection sishiya udonga lwe-membrane nodonga lokuhlukanisa; Isixha sesibili sodonga olufanele lwe-membrane nodonga lokuhlukanisa. Isigaxa sokuqala se-Tonxction Tube ukuhwamuka komhlaba wokushisa, kanye neshubhu le-Tonction Coupction lesibili liphansi kwesigubhu esiphezulu.
I-D-Type Boiler ayinalo uhlaka, futhi kuyisakhiwo esisekelayo. Isakhiwo sihlangene, umsebenzi mncane, isisindo sikhanya, ukufakwa komsebenzi okuku-kusayithi kuncane futhi kushesha isivinini sokufaka. Ngakho-ke, ilungele amaphrojekthi aphesheya kwezilwandle ngesikhathi sokulethwa okuqinile.
2. Amapharamitha aphambili we-D-Type Boiler
| Cha. | Into yendaba | Thanda |
| 1 | Umthamo olinganiselwe (t / h) | Umfana no-180 |
| 2 | Ingcindezi yeSteate Superheated (MPA) | 4.1 |
| 3 | Amazinga okushisa amunca ngokweqile (℃) | 400 |
| 4 | Okuphakelayo Ukushisa kwamanzi (℃) | I-120 |
| 5 | Ukuphakelwa kwengcindezi yamanzi (MPA) | 6.2 |
| 6 | Ingcindezi yokuqamba iDrum Design (MPA) | 4.45 |
| 7 | Ubukhulu (m) | 11x8.7x10.3 |
| 8 | Isisindo esiphelele (ithoni) | 234 |
Kubandakanya ikakhulukazi ama-boiler amabili we-180T / h3 ithangi lamanzi, ne-chimney eyodwa yensimbi engu-90m. Isikhungo samanzi esingu-450t / h esimisiwe (i-deaarator, iphampu ye-deaarator, idivaysi ye-deoxidant dosing, njll.). I-boiler ngayinye yegesi inamasethi ayisithupha Steam Soot Bloowers ngohlelo lokulawula okuzenzakalelayo. Amasethi amane abuyiselwe ngokuphelele ama-soot emzimbeni we-boiler, futhi ama-swoot ama-soot abuyiselwe amabili angokomfula. I-boiler ngayinye ine fan eyodwa ye-FD, futhi ama-boilers amabili egesi abelana nge-chimney eyodwa (ukuphakama kwama-90m, ububanzi obuphumayo 3.3m). Ithangi lokunwetshwa okuqhubekayo okuqhubekayo, ithangi lokunwetshwa kwe-Intermitlent blowdown kanye nokuphola kuyatholakala. Ama-drainage aqhubekayo ngemuva kokupholisa kumanzi okwenziwa kwamanzi ajikelezayo.
3. Izici zokuhlanganisa ze-D-Type Boiler
I-Steam Stieber ngayinye ine-Durser engu-4 (amandla alinganiselwe owodwa 48.7 MW). Lapho usebenzisa igesi kaphethiloli, umthwalo wokukhiqiza ungama-25% -110% umthamo olinganiselwe; Kusetshenziswa uwoyela kagesi, umthwalo ungama-35% -110% umthamo olinganiselwe.
3.1 Uhlelo lwamanzi amusha
Umthamo wamanzi ohleliwe ngu-420t / h, kanye nokuqukethwe kwe-oxygen kungu-7μ / g. Inqubo condensate yatholakala futhi yaphathwa njengamanzi okuphakelwa kwama-boiler, nenani le-PH ngu-8.5-9.5. Ine-Preseter yamanzi yokuphakelayo eyingqayizivele.
3.2 Flue igesi nohlelo lomoya
I-Steam Steam ngayinye ine fan eyodwa ye-FD ene-design yomoya yevolumu engu-4026 m3 / min. Ingcindezi yomoya eFD Fan Outlet ingu-3.16 KPA, futhi i-Flue Pur Pres Transcient ngaphambi ko-Economizer yi-0.34 KPA.
3.3 uhlelo lokulawula okuzenzakalelayo
Kubandakanya ukulungiswa okuzenzakalelayo kokuhlinzekwa kwamanzi, inqubo yokuhlanza kanye nokushisa okushisayo okuphezulu, nokulahla okuzenzakalelayo, ukushaya i-soot kanye nokuqhuma. Uhlelo lwe-BMS luqoqa ingcindezi yothando, izakhiwo zikaphethiloli, izinga lamanzi wesigubhu, okuqukethwe kwegesi ye-flue axygen, bese kuguqula i-burner ngokufanele.
