Boiler grate bar inotaurwa seketani yemoto, iyo inokonzeresa kupfuura 70% yehuwandu hwehuwandu hwemaindasitiri. Munguva yakapfuura, marasha akagoverwa kwenguva pfupi, saka chero marasha anogona kushandiswa kuchirimo, asi mhando yemarasha anopa kazhinji haikwanisi zvinodiwa nemabhodhi emachira, zvichikonzera kutambisa kwemarara. Kana iyo marasha emhepo yakawandisa, kunyanya kana isingasviki 1mm, yekubhururuka kurasikirwa; Kana marasha mazhinji akawandisa, kusakwana kwehunhu kunosiya chikanganiso. Tichifunga nezvekushandiswa kwemazimbe kwevira yemhando yemamirioni nemazana emamirioni ematani pagore, saka "matekinoroji emarasha eketani grate boiler" GB / T 18342-2001 yakagadzirwa.
Kwemaketeni boiler mukushandiswa, saizi yemarasha emarasha haafanire kupfuura 50mm, asi iyo maratidziro emugodhi asingasviki 6% yemarasha ese akashandiswa; Kana iyo yekupedzisira marasha asingasviki 30mm (kana 25mm) anoshandiswa, iyo marasha emugodhi asingasviki 3ram anofanira kunge ari pasi pe30%. Iyo ger yemarasha emicherechedzo cheni iri nani pane isingasviki 30%, asi iyo gayo haifanire kunge yakaderera, kazhinji 10% ~ 30% ~ 30% ~ 30%. Iyo isina kujairika zvirimo zveganda inofanira kutsanangurwa maererano nekugadzirwa kwemugodhi wemubhoti. Kune iyo ketani yechirambidziro neAnthincite, iyo yakasvibira yezvemukati inofanira kunge iri 6.5% ~ 10%; Iko hakuna muganho pane yakajeka yezvinyorwa zvemabhandi mangozi yebhandi. Iko kukosha kweCalarific yeCalal inofanirwa kunge yakakura kupfuura 21 mj / kg (500 kca / kg) yeanthracite, uye haifanirwe kunge iri pasi pegumi nemana / kg) yeBituminius ie. Iyo Coke Slag hunhu (CRC) yemarasha haapfuuri 5, zvisizvo zvikashandiswa bongozozo remubati rakasimba kwazvo richanyanyisa kuchaita muvira uye rinobata pakurwidzira. Iyo ger inonyunguduka ichipenya kupisa Zvinyorwa zveSarufa zvinotsanangurwa maererano nezvinodiwa zvekudzivirira kwezvakatipoteredza, kana sarufa zvemarasha mune mamwe maCocal mune imwe nzvimbo Kana iyo sarufa yezvinyorwa zvakanyanyisa, iyo marasha ekubatanidza nzira inogona kushandiswa kuderedza iyo sulfa yezvinyorwa kuti isangane nezvinodiwa zveMubhoti emhepo.
