Biogas Generator Teeb Radiators (Common Dry Coolers / High- Thiab Tsawg-Tsuas Kub-Cooled)

Apr 13, 2026

BiogasGenerator Teeb Radiators(Feem ntau Qhuav-Hom Cua Txias / Sib cais siab- thiab qis-Tsuas txias)

Biogas yog heev humid, corrosive, thiab muaj ntau impurities. Yog li ntawd, lub tshuab hluav taws xob tsim qhov tseem ceeb tshaj plaws rau kev tiv thaiv corrosion, tiv thaiv thaiv, thiab cais siab - thiab qis - qhov kub thiab txias. Hauv kev xyaum ua engineering, qhuav- hom cua txias yuav luag tsuas yog siv, thiab cov dej txias yees tsis ua haujlwm.

Txhawm rau kom muaj txiaj ntsig thiab siv tau ntev, cov tshuab biogas feem ntau siv ob lub tshuab cua txias:

High -Circuit Kub (HT)

Cua txias: Lub tog raj kheej liner dej, cav thaiv

Kub: 85-95 ° C

Muaj nuj nqi: Tiv thaiv lub cav overheating thiab tswj kom ruaj khov thermal efficiency

Tsawg-Circuit Kub (LT)

Cua txias: intercooled cua, cav roj, biogas preheater

Kub: 55-70 degree

Muaj nuj nqi: txo qis cua sov kom tsawg, tiv thaiv cov roj cav, thiab ua kom huab cua ruaj khov - roj piv

Txhua lub voj voog yog nruab nrog lub tshuab hluav taws xob tshwj xeeb, sib sau ua ke hu ua siab - thiab qis - kub txias txias.

Qhov sib txawv ntawm Radiators hauv Pa Diesel / Natural Gas Cav

Txhim kho Corrosion Resistance

Biogas muaj H₂S thiab dej vapor, uas yog corrosive heev; fins thiab kav dej yuav tsum yog corrosion-resistant.

Yooj yim ntxuav

Biogas muaj ntau yam impurities, thiab cov fins cua txias yuav ua rau txhaws; tus tsim yuav tsum ua kom yooj yim ntxuav dej thiab cua tshuab.

Stricter Temperature Control

Biogas tus nqi calorific fluctuates ho; Qhov kub tsis ruaj khov nyob rau hauv qis- qhov kub thiab txias Circuit Court ncaj qha cuam tshuam rau lub zog tso zis thiab qhov kub ntawm qhov tso tawm.

Kev tiv thaiv lub caij ntuj no khov

Ethylene glycol antifreeze feem ntau yog siv los tiv thaiv cov yeeb nkab tawg vim khov.

 

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.
