600kw Biogas Generator for Plants

Designed for continuous duty at centralized biogas plants, the 600kw Biogas Generator for Plants is built by Kecheng (Shandong Kecheng Electric Power Equipment Co., Ltd., China). This unit handles CH₄ 45%–60% with a fixed compression ratio of 12.5:1 and closed-loop lambda control – no dual‑fuel compromise. The package integrates a pretreatment skid (dual‑vessel desulfurizer with online switching, automatic condensate drain, 5μm filtration), a Stamford or Marathon alternator, and a PLC that manages auto start/stop, load sharing, and seamless island/grid transition. Each generator is full‑load tested for 4 hours on real biogas before shipment. Price includes on‑site commissioning, 2‑day operator training, and a 2‑year warranty. Manufacturing facilities are ISO9001 and ISO14001 certified, ensuring consistent quality and environmental compliance.

Before You Install: Six‑Point Checklist

Step‑by‑Step Operational Guide (Once Delivered) 

Step 1 – Gas pretreatment startup

- Fill desulfurizer vessels with iron oxide media (supplied in 25kg bags).

- Set automatic drain timer for condensate trap (default: every 2 hours, 10 seconds).

- Verify gas pressure at generator inlet: 10–30 mbar.

Step 2 – First start (island mode)- Close main breaker to plant load (no grid connection yet).

- Press Start on PLC panel – the unit will purge, pre‑lubricate, ignite, and ramp to idle.

- After 2 minutes idle, press Load – unit takes 0% to 100% load automatically based on demand.

Step 3 – Grid parallel (optional)- Obtain grid interconnection approval.

- Set PLC to Grid mode. Unit synchronizes voltage, frequency, and phase before closing tie breaker.

- Excess power is exported; plant load is shared between generator and grid.

Step 4 – Daily checks (10 minutes per shift)- Record gas pressure, CH₄ reading (from PLC), engine temperature, and exhaust temperature.

- Inspect condensate drain for water carryover.

- Listen for unusual knock or hissing.

A laminated quick‑start poster is attached to each control panel.

After‑Sales Service: What You Actually Get

Kecheng does not rely on third‑party dealers. Service is handled directly from our regional centers. We offer great services for our 600kw Biogas Generator for Plants!

Included in the price (no extra cost)- One on‑site commissioning trip (up to 5 days) – our engineer starts the unit, trains your team, and signs off.

- 10‑year spare parts availability commitment.

- 24/7 remote support via WeChat/WhatsApp/TeamViewer – response within 2 hours. Optional (fee‑based)- Annual maintenance contract – includes two routine service visits, consumables, and priority hotline.

- Remote monitoring platform (cloud dashboard)

– view all running parameters on your phone.

Spare parts kit recommended (one‑time purchase)

- 4 spark plugs, 2 oil filters, 2 air filters, 1 set of gaskets, 1 pressure sensor, 1 CH₄ sensor.

- Price: 5% of generator cost – enough for 2,000 operating hours.

 Why Plant Managers Choose This Model 

- No fuel blending required – runs on 100% biogas without natural gas support, unlike many biogas‑ready units that actually need 5–10% diesel or natural gas for stability.

- Heat recovery ready – optional exhaust gas heat exchanger can preheat digester feed, raising overall plant efficiency above 80%.

- Siloxane tolerance – optional adsorption filter available for biogas from landfill or industrial waste.

- Proven in continuous duty – over 120 units installed in Chinese biogas plants with average uptime >95% (verified by remote monitoring logs).
