Kupa simba iyo "Mwoyo Wakasimba" weGlobal Boilers: Nei Vatengi Vakasimba Pasi Pose Sarudza Yedu Yakagadzirirwa Boiler Grates
Muminda yemaboiler emaindasitiri, kugadzirwa kwemagetsi ebiomass, neKurasa-ku-Energy (WTE) zvirimwa, bhodha gireti (Boiler Grate / Grate Stoker) inozivikanwa se "moyo" yemagetsi ese. Senyanzvi yekugadzira yakadzika-yakadzika midzi muR&D nekugadzira masisitimu egireti kwemakore akawanda, tinoziva isu pachedu kuti chero kudzima kusina kurongwa kana kugadzirisa kwegeti system (Grate System) kunogona kudhura chirimwa makumi kana mazana ezviuru zvemadhora pazuva.
Vatengi vekumhiri kwemakungwa-kunyanya vatengi vekuGermany nevekuEurope vane mukurumbira wetsika dzakasimba-vanotarisa Total Cost of Ownership (TCO) pakusarudza magrate bar (Grate Bars / Grate Tiles). Kudzingirira mutengo wakaderera wekutanga usingaoni kazhinji kunoshandura kumitengo yakakurisa yezvimedu zvakasara (Grate Spare Parts) uye njodzi dzakakomba dzekudzikira gare gare.
Nhasi, senyanzvi dzekugadzira zvinhu, tinoda kugovera mafungire atinoita pamusoro pezvese zvinhu, magadzirirwo, uye kutumira kuti tive shamwari yakavimbika,{0}}yenguva refu yevatariri vezvekutenga zvinhu.
1. Hardcore Metallurgy: Kuzvipira "Kurebe-Upenyu" Kupfuura Magiredhi Ezvinhu
Grate plates (Grate Plates) anoshanda nguva dzose pasi pemamiriro ekunze ekunyanya kupisa, kusakara kwakanyanya, uye kukora kwakanyanya (sekupisa-temperature chloride corrosion mukupisa tsvina). Hatina kumbocheka makona pazvinhu. Pane kudaro, tinopa-tier heat and wear-resistant alloy (Heat & Wear Resistant Alloys) magadzirirwo anoenderana nenzvimbo dzakasiyana dzevira nemhando dzemafuta:
Main Combustion Zone yeWaste Incinerators: Isu tinoshandisa -chromium cast iron grate mabharu akakwirira (Yakakwirira-Chromium Cast Iron Grate Bars, akadai seGx300CrMo27-1 / 1.4855) ine chromium ($Cr$2% inodzorwa) yakasimba pakati pe2%. Nyaya iyi inoumba dense $Cr_2O_3$ inodzivirira layer pamusoro, yakanyatsogadzirwa kurwisa yakasindimara yepamusoro-tembiricha chloride corrosion uye zvakanyanya kuwedzera hupenyu hwesevhisi (Grate Service Life).
Biomass High-Temperature Zone: Kurwisa kuora kwesimbi yealkali uye kushanduka kwekushisa kwakanyanya, tinokurudzira austenitic heat-resistainable steel/cast steel grates (seG-X40CrNiSi25-20 / 1.4848). Yayo yakasarudzika yekupisa kuvhundutsa kuramba inoita kuti grate iwane "zero kupaza" pasi pekutanga kutanga uye nekukasira kushanduka kwekushisa.
Iyo "Isingaonekwi Hunhu" Isu Isu Tinoendesa: Kusangana kwemakemikari emugadzirirwo ingori yekutanga. Tisati tasiya nzvimbo yedu, batch yega yega yezvigadzirwa inoongororwa metallographic (Metallographic Analysis) kuve nechokwadi chekuti eutectic carbides yakanaka uye isingaenderere mberi $M_7C_3$ mhando, ichibvisa zvachose iyo inoenderera network zvimiro zvinokonzeresa brittleness uye kutsemuka. Uyezve, chikamu chega chega chinowana kushushikana kwakanyanya-kubvisa kupisa, zvichitsigirwa netembiricha yakakwana-machati enguva, kuve nechokwadi chekuti zero deformation kana yaiswa muchoto.
2. Ingenious Engineering: Kuwedzera Kukosha KweKilogram Yese Yemafuta
A grate haisi muunganidzwa wezvakareruka castings; ndiyo yakanyanya kuomesesa mechanical grate firing system (Mechanical Grate Firing System). Chikwata chedu cheinjiniya chine yakasimba dhizaini dhizaini kuti ive nechokwadi chekuti girati rinoenderana neako chaiwo maitiro emafuta:
Zoned Accurate Air Supply (Zoned Air Supply / Primary Air Distribution): Ingave iri reciprocating grate (Reciprocating Grate), cheni gireti (Chain Grate / Traveling Grate), kana dumping grate (Dumping Grate), yedu air plenuis zvimiro zvinotsigira akawanda-stage, yakazvimirira kugovera, uye yakazvimirira. Izvi zvinonyanya kuwedzera boiler kupisa kunyatsoshanda uye kunoderedza kusapisa kabhoni kurasikirwa (Unburnt Carbon Loss).
Micron-Level Thermal Expansion Gap Control (Thermal Expansion Gap): Zvichienderana nemakore ekuunganidzirwa kwedhata rekuyezera kusimuka kwemafuta, tinogadzira kubvisisa kwacho pakati pemabharu egireti anofambisa (Moving Grate Bars) nemabhawa akagadziriswa (Fixed Grate Bars). Izvi zvinoderedza kusefa kwegireti (Grate Siftings) uye kuvuza kwedota uku uchidzivirira zvakakwana jamming yezvinhu kana kupisa kunokonzerwa nekuwedzera kupisa.
Hungwaru Kuwedzeredza Dziviriro: Yedu grate drive system (Grate Drive System, hydraulic kana mechanic) inoshongedzerwa neaviri akawandisa ekudzivirira maitiro. Kana chimedu chihombe che-chekunze chinobatika chikazadzwa muchoto, sisitimu inodaira uye inorira ipapo ipapo, ichidzivirira matanda ese epa grate (Grate Beams) uye magadzirirwo kubva pakukuvadzwa kukuru.
3. Dependable Service: "Zero-Risk" Global Delivery
Kune vatengi vekune dzimwe nyika, kusava nechokwadi ndiyo mutengo wepamusoro. Kubva pakudhirowa simbiso kuenda kutransoceanic delivery, tinopa chokwadi chakakwana mukati mese maitiro:
International Passport to Compliance: Yedu yekugadzira uye welding maitiro anoenderana zvizere neASME uye EN zviyero. Zvikamu zvega zvega zvezvigadzirwa zvinounzwa neEN 10204 3.1 Chitupa (Material Mill Certificate), zvichiita kuti zvikunetsei-kuparura mahara uye kutevedzera mitemo yako.
Pa-Time Delivery (OTD): Zvirongwa zvekugadzirisa zvirimwa (Outage / Shutdown) zvakarongwa kusvika pazuva. Tinonzwisisa zvikuru kuti nguva imari; saka, isu tinopa zvinoonekwa kugadzirwa uye Logistics tracking kuvimbisa kuti zvinhu zvako zvinosvika panzvimbo yacho chaizvo panguva yakatarwa.
Ocean-Grade Protective Packaging: Kuti tishingirire mavhiki kana mwedzi yekufamba nemugungwa, tinoisa-layer protection tichishandisa mabhegi eVapor Corrosion Inhibitor (VCI), akakwirira-anodzivirira{3}}oiri yerust, uye akasimba, mabhokisi emapuranga asingabhadharwi. Izvi zvinoita kuti zvigadzirwa zvisvike panzvimbo yako yemhiri kwemakungwa "zvisina ngura-zvemahara" uye zvakachena sezuva ravakabva kufekitori.
