Katsi majan aten hta pat da ai circuit katsi ai nta hpe galaw ai a madung gaw 2010 ning hta nga ai.anti-katsi ai hpe makawp maga ai, hkyet ai/hka ai masa hpe galai shai ai, parameter hpe grau kaja hkra galaw ai, jep joi ai lam hte gram lajang ai lam. Coil hte pipeline ni hpe katsi mat ai hte n-gun n rawng hkra makawp maga ra ai sha n-ga, katsi mat ai lam hpe mung, jak rung ni hpe mung shim lum hkra galaw ra ai. Operation plan hpe bungli galaw ai ladat, grup yin nbung katsi ai hte system configuration ni hpe yu nna galaw ra ai.

 

 

 

1. Pre-Hkringhtawng Anti-Freeze hpe hkyen lajang ai lam (Hkringhtawng garai n du shi yang galaw ra ai)

System hpe n-gun shaja ya ai

Tower shell, nbung galai shai ai coil ni, shang/pru ai pipe ni, hka lim ai pipe ni, valve ni hte hka shinggyin ai pan hpe 50mm jan na nlung shingnip (sh) polyurethane insulation layer hte ka-up nna, shinggan layer hta hka n shang hkra tsi lajang da u.℃hta shamu shamawt nna 8℃hta jahkring kau na matu, npu-nga ai pipe daw ni hte si mat ai shara ni hpe madung tawn nna, n-gun n-gun hpe hkang ai linkage hpe hpaw da ai pipeline ni hta self-regulating electric heating tapes ni hpe jung da u.

 

Anti-Hka lim ai tsi hpe hkyen lajang ai

Hka kata na n-gun (process hka maga) de ethylene glycol (sh) propylene glycol n-gun shayawm ai tsi hpe bang dat u. Dai n-gun hpe buga na n-gun yawm dik htum nbung katsi ai hte maren gram lajang u (ga shadawn. 30% ethylene glycol -15℃grup yin a matu), nbung katsi ai shara gaw grup yin nbung katsi ai hta 5–10℃yawm ai hpe sadi ra ai. Htap htuk ai n-gun shayawm ai tsi hte galai kau u.

 

Hka lim ai hte jasan jaseng ai

Aten galu pat da ai arung arai ni a matu, hka pru ai shara hte hka pru ai valve yawng hpe hpaw nna, ngam ai hka hpe coil, spray pipeline hte hka shinggyin ai pan ni hta nbung n-gun n rawng hkra atsawm sha jasan jaseng kau ra ai. - aten kadun laman pat kau na matu, kata na hka lim ai lam hta matut manoi lwi nga ai hpe matut manoi galaw u.

 

Tinang hkrai hkang ai ladat hpe galaw hpang wa ai

Set low-katsi ai hpe bai nhtang wa ai shaloi hka katsi ai 5℃hta n-pu (sh) maren sha rai yang, fan a nsen hpe shayawm/htum kau ai hte spray pump hpe hpaw/jahkring kau ai hte matut mahkai da ai. Hka shinggyin ai pan hpe wan n-gun hte n-gun n-gun n-gun n-gun n-gun n-gun n-htum hkra (liquid level interlock) bang da u.

 

 

 

2. Magam bungli galaw ai aten hta Anti-Freeze hte Parameter hpe grau kaja hkra galaw ai lam (Core bungli galaw ai lam)

 

Hka kata na hka hkawm ai lam (Process Water Side): Hka lwi ai hte n-gun n rawng ai nbung hpe makawp maga ya ai

 

Shutdown (sh) lwi ai lam hpe pat kau ai lam n nga ai

N-gun n law ai aten hta pyi, n law htum kata na hka lwi ai lam ( Design flow a 30% hta grau kaba ai (sh) maren sha) hpe hkan sa ra ai. Coil ni hta hka n htum hkra bypass valve (sh) karum ai pump hpe lang mai ai.

 

Katsi ai hpe hkang ai

Hka n-gun hpe 8–15℃hta hkang lu na matu hkang u. Katsi ai nbung katsi galai shai ai lam hpe shayawm na matu, nbung katsi ai shara hta fan a lawan ai hpe pat kau (sh) shayawm kau u. Grai n-gun n law ai shara ni hta, hka n-gun hpe n-gun jaw na matu, hka n-gun hpe n-gun jaw na matu, process waste heat hpe lang u.

 

Antifreeze hpe yu reng ai

Antifreeze a n-gun hte freezing point hpe bat shagu jep yu nna, n-gun yawm mat ai majaw hkrat sum ai lam n byin na matu aten dep bai jat bang ra ai.

 

Shinggan de hka hkawm ai lam (Spray Water Side): Katsi ai-Hkang lu ai Hpang/Hkring ai hte Hkring/Hka Hkrang galai shai ai lam

 

Hka hte bungli galaw ai

Degree hta grau ai (sh) dai hte maren sha nga ai shaloi, shingra tara hku hka garan ai. Hka n-gun 5-7℃de hkrat wa ai shaloi, hka garan ai pump hpe shi hkrai shi jahkring kau u. Hka hpe 4℃hta grau ai (sh) dai hte maren sha tawn da na matu hka shinggyin ai hka htung hta wan n-gun rawng ai jak hpe bang da u .

 

Katsi ai bungli

Htingbu htingbyen nbung katsi ai lam matut manoi nga ai shaloi<0℃, completely drain the spray system, turn off the spray pump, and use only fan air cooling (full dry mode) to completely eliminate the risk of spray water freezing.

 

Kalang lang hka garan aiLama na

hka garan ra ai, kadun ai-cycle hpang/jahkring ai (ga shadawn, minit 10 gat ai, minit 20 jahkring ai) hpe hkap la nna, hka garan ai pipeline ni hta heat tracing insulation hpe bang u.

 

Fan hte nbung nsen hpe gram lajang ai

Galai shai ai frequency hpe hkang ai hpe lang u. Lawan ai hpe shayawm kau u (sh) n-gun n law ai shara ni hta kalang lang gat u. Parallel multiple tower ni a matu, tower langai a katsi ai n-gun hte pru ai hka n-gun hpe jat ya lu na matu hte hka lim ai lam hpe shayawm ya lu na matu, concentrate load galaw ai lam hpe galaw ra ai.

 

 

 

3. Shutdown hte Restart galaw na matu masat da ai lam ni

Aten kadun-htum mat ai ( Hkying hkum 72 hta n law ai (sh) maren sha re)

Hka kata na circulation pump hpe n-gun dat nna, bypass hpe hpaw nna, hka n-gun hpe 5℃hta grau ai (sh) dai hte maren sha tawn da ai ; spray system hpe hka ja kau nna, katsi ai hpe n-gun n jaw ai insulation hpe tawn da u.

 

Long-term shutdown (>Hkying hkum 72)

Dai zawn re ai nbung hpe atsawm sha hka ja kau nna, kata na nbung lwi ai hte hka garan ai ladat hpe compressed air hte jasan jaseng kau nna, valve yawng hpe pat kau nna, atsawm sha pat da ra ai. Dai coil ni hta antifreeze loi mi bang nna makawp maga mai ai.
