Biomass Fuels BoilerNyob rau hauv thailand tsuas hlawv cov khoom khib nyiab los ntawm kev ua liaj ua teb thiab ua ntoo. Raws li cov kev lag luam roj carbon tsawg, lub zog tsis txaus thiab cov chaw ib puag ncig, Thaib teb tsoomfwv tau npaj lub zog ua kom muaj kev npaj kho dua tshiab. Cov lus no tso rau tom ntej kev txheeb xyuas qhov kawg, pob kws tshuaj tua kab, pob txha, muab cov ntaub ntawv ntsuas kev sim ua lag luam rau kev lag luam biomass zog Thailand.
1.1 Kev Ntsuam Xyuas Kev Ntsuam Xyuas Qhov kawg ntawm Biomass roj raws li tau txais hauv paus
| Roj Hom | C | H | O | N | S | Cl |
| Fusk | 37.51 | 3.83 | 34.12 | 0.29 | 0.03 | 0.20 |
| Pob Kws COB | 13.71 | 0.81 | 35.04 | 0.31 | 0.03 | 0.11 |
| Txoj kas | 21.33 | 3.06 | 23.29 | 0.13 | 0.03 | 0.04 |

Piv nrog thee, c cov ntsiab lus nyob rau hauv roj biomass yog qis dua; H ntsiab lus yog zoo li. O Cov ntsiab lus o yog ntau dua; N thiab s cov ntsiab lus yog tsawg heev. Cov txiaj ntsig qhia tau hais tias cov ntsiab lus cl yog qhov sib txawv heev, nrog cov nplej husk 0.20% thiab xibtes Hub tsuas yog 0.02%.
1.2 Kev txheeb xyuas cov roj biomass
| Roj Hom | Txhos | Dej | Ywj pheej | Tsau Carbon | GCV KJ / kg | Ncv KJ / kg |
| Fusk | 13.52 | 10.70 | 80.36 | 14.90 | 14960 | 13917 |
| Pob Kws COB | 3.70 | 46.40 | 84.57 | 7.64 | 9638 | 8324 |
| Txoj kas | 1.43 | 50.73 | 87.7.75 | 5.86 | 9243 | 7638 |
| Cov xib teg fiber ntau | 6.35 | 31.84 | 78.64 | 13.20 | 13548 | 11500 |
| Lub xibtes | 3.52 | 12.00 | 80.73 | 16.30 | 18267 | 16900 |
| EFB | 2.04 | 50.80 | 79.30 | 9.76 | 8121 | 6614 |
| Eucalyptus tawv ntoo | 2.45 | 52.00 | 82.55 | 7.72 | 8487 | 6845 |
Tsuas yog cov pob ua hmoov, cov hmoov tshauv ntawm cov roj biomass so yog qis tsawg dua 10%. Cov teeb meem tsis muaj teeb meem ntawm cov hmoov tshauv qhuav-dawb heev yog heev, xws li ntawm 78.64% rau 87.75%. Cov khaub ncaws Husk thiab Palm Plhaub muaj qhov zoo tshaj plaws imperition cov yam ntxwv.
Hauv xyoo 2009, biomass boiler chaw tsim tshuaj paus Taiseban pab pawg tau sib cog lus lub zog tsob nroj boiler hlawv cov plaub hau thiab efb hauv Thaib teb. Cov biomass Fuels Boiler yog ib qho 35t / h nruab nrab kub thiab nruab nrab kub kauj ruam grate boiler. Tus qauv tsim sib xyaw piv ntawm cov xib teg rau EFB yog 35:65. Cov biomass fuels butterts ob-theem fullingrocating grate kom cais cov chaw ziab khaub ncaws los ntawm thaj chaw sib txuas. Nyob rau hauv thawj-theem reciprocating grate, cov roj yog radiated los ntawm lub hauv ntej koov, nyob rau hauv cov dej twg yog lawm. Tom qab thawj-theem reciprocating grate kis tau cua, thiab li 50% ntawm cov txiv qhuav dej ua ke rau hauv qhov cub. So ib feem poob rau ntawm ob-theem ua tiav grate rau kev sib txuas. Xibtes fiber ntau thiab cov roj av roj khoob muaj cov cuab yeej coking.
Nyob rau hauv 2017, peb tau ua lwm 45t / h sub-siab thiab sub-siab zog fais fab boiler hauv Thaib teb. Peb txhim kho yav dhau los π-puab txheej rau cov qauv m hom tshiab. Cov biomass cov roj boiler tau muab faib ua hluav taws xob, txias Chamber thiab chav SuperHeatre. Kev lag luam sab saud, ua ntej huab cua ua ke, txo kev lag luam qis dua thiab ua ntej huab cua hauv lub pas dej Tail. Tshauv hoppers nyob hauv qab txias chamber thiab supertheatre chamber kom sau ya cov tshauv.
1. tsom xam cov hmoov fusion yam ntxwv
| Roj Hom | Deformation kub | Muag kub | Hemispherical kub | Ntws tawm kub |
| Fusk | 1297 | 1272 | 1498 | 1500 |
| Pob Kws COB | 950 | 995 | 1039 | 1060 |
| Txoj kas | 1040 | 1050 | 1230 | 1240 |
| Cov xib teg fiber ntau | 1140 | 1160 | 1190 | 1200 |
| Lub xibtes | 980 | 1200 | 1290 | 1300 |
| EFB | 960 | 970 | 980 | 1000 |
| Eucalyptus tawv ntoo | 1335 | 137 | 1385 | 1390 |
Cov hmoov tshauv fusion taw tes ntawm cov fusk yog qhov siab tshaj plaws, thaum pob kws cob thiab xibtes roj cab yog qhov qis tshaj.
1.4 Kev Sib Tham
High Calorific tus nqi ntawm cov fuag husk thiab palf plhaub nce kev sib xyaw ua ke hauv kev cub thiab txo hluav taws xob cua sov. Vim tias cov ntsiab lus noo noo, nws tuaj yeem txo cov cua sov vim kev ua pa tawm thiab txhim kho cov cua sov ua haujlwm. Txawm li cas los xij, cov tshuaj chlorine hauv cov kev sib xyaw ua ke husk yog qhov siab, thiab qhov hloov tau yooj yim rau kev ua kom haum thiab coke hauv thaj chaw supertheater. Xibtes Plhaub muaj lub siab Calorific, qis hmoov tshauv fusion taw tes thiab siab k cov ntsiab lus hauv tshauv. Nws yog qhov tsim nyog yuav tsum tau kho cov kev npaj ntawm kev sib txuas thiab cua sov ua kom txo cov roj qis qis kom txo tau cov pa hluav taws xob tsawg dua los daws cov cua sov thiab superheater.
Pob kws cob, polm fiber ntau thiab cov roj roj nchuav cab muaj siab cl thiab k, thiab qis hmoov tshauv fusion taw tes. Yog li ntawd, qhov chaw ua haujlwm yooj yim yuav tsum muaj alloy steel nrog muaj zog corrosion tsis kam (xws li Tp347H).
Baglse thiab eucalyptus cov tawv ntoo muaj ntau dua cov ntsiab lus noo noo vim muaj hluav taws kub ua rau kom huv thiab qis dua. Npaj radiant tsim nyog thiab convective cua sov sab qab teb, ua kom cua sov kom sov, thiab superHeater yuav tsum muaj qhov kub txaus thiab siab. Nws yog ib qho tsim nyog los xaiv alcoloy steel nrog muaj zog corrosion muaj zog rau superHeater.
1.5. Xaus thiab lus qhia
(1) Cov Husk thiab Palatile muaj cov dej noo qis, muaj teeb meem siab tshaj plaws, yog li nws tuaj yeem sib xyaw nrog lwm cov roj qis uas muaj kev ua haujlwm tsawg.
(2) Pob kws cob, pranf fiber ntau thiab cov roj roj khoob muaj cov chlorine cov ntsiab lus thiab qis hmoov tshauv. Qhov chaw ua haujlwm yooj yim yuav tsum muaj alloy steel nrog muaj zog corrosion tsis kam.
(3) bagasse thiab eucalyptus cov tawv ntoo muaj tsawg calorific tus nqi thiab siab tshauv fusion taw tes, yog li kev pheej hmoo ntawm cov coking nyob rau hauv lub cub tawg yog tsawg.
