Radyatè ansanm ak dèlko biogaz (Komen glasyè sèk / segondè{0}} ak ba-lè tanperati-refwadi)

BiogazDèlko Mete radyatè(Anjeneral sèk-Type Air Coolers / Separe High- ak Ba-Refwadisman Tanperati)

Biogaz se trè imid, korozivite, epi li gen anpil enpurte. Se poutèt sa, konsepsyon radyatè yo bay priyorite rezistans korozyon, prevansyon bouche, ak separe refwadisman segondè- ak ba-tanperati. Nan pratik jeni, seche -tip lè fre yo itilize prèske sèlman, epi gwo fò won refwadisman dlo yo pa anplwaye.

Pou asire efikasite ak lonjevite, motè biogaz jeneralman anplwaye de sistèm refwadisman endepandan:

Sikwi Tanperati segondè-(HT)

Refwadisman: Dlo revètman silenn, blòk motè

Tanperati: 85-95 degre

Fonksyon: Anpeche motè surchof epi kenbe efikasite tèmik ki estab

Sikwi Tanperati ba-(LT)

Refwadisman: Intercooled lè, lwil motè, biogaz prechofaj

Tanperati: 55-70 degre

Fonksyon: Diminye tanperati lè admisyon an, pwoteje lwil motè, epi estabilize rapò gaz -lè a.

Chak sikwi ekipe ak yon echanjeur chalè dedye, yo rele kolektivman kòm glasyè sèk tanperati ki wo - ak ba-.

Diferans ak radyatè nan motè konvansyonèl dyezèl/gaz natirèl

Amelyore rezistans korozyon

Biogaz gen H₂S ak vapè dlo, ki trè korozivite; najwa ak kanalizasyon yo dwe reziste -kowozyon.

Pi fasil pou netwaye

Biogaz gen anpil enpurte, ak najwar refwadisman yo gen tandans bouche; konsepsyon an dwe fasilite lave dlo ak lè mouche.

Kontwòl Tanperati pi strik

Valè kalorifik biogaz varye anpil; Tanperati enstab nan sikwi tanperati ki ba-la dirèkteman afekte pwodiksyon pouvwa ak tanperati echapman.

Pwoteksyon konjel ivè

Antijèl ethylene glycol se souvan itilize pou anpeche pete tiyo akòz konjelasyon.

 

Biogas Generator Set Radiators (Typically Dry-Type Air Coolers / Separate High- and Low-Temperature Cooling) Biogas is highly humid, corrosive, and contains many impurities. Therefore, radiator designs prioritize corrosion resistance, clog prevention, and separate high- and low-temperature cooling. In engineering practice, dry-type air coolers are almost exclusively used, and water cooling towers are not employed.  To ensure efficiency and longevity, biogas engines generally employ two independent cooling systems: High-Temperature Circuit (HT) Cooling: Cylinder liner water, engine block Temperature: 85–95°C Function: Prevents engine overheating and maintains stable thermal efficiency Low-Temperature Circuit (LT) Cooling: Intercooled air, engine oil, biogas preheater Temperature: 55–70°C Function: Lowers intake air temperature, protects engine oil, and stabilizes the air-fuel ratio Each circuit is equipped with a dedicated heat exchanger, collectively referred to as high- and low-temperature dry coolers.  Differences from Radiators in Conventional Diesel/Natural Gas Engines Enhanced Corrosion Resistance Biogas contains H₂S and water vapor, which are highly corrosive; fins and piping must be corrosion-resistant. Easier to Clean Biogas contains many impurities, and cooling fins are prone to clogging; the design must facilitate water washing and air blowing. Stricter Temperature Control Biogas calorific value fluctuates significantly; unstable temperatures in the low-temperature circuit directly affect power output and exhaust temperature. Winter Freeze Protection Ethylene glycol antifreeze is commonly used to prevent pipe bursts due to freezing.
