Product Description

CNG Generator

This CNG generator set is a clean, efficient power solution powered by compressed natural gas. Designed for industrial and commercial applications, it combines advanced gas engine technology with high-performance alternators to deliver stable, reliable electricity.
 
With low fuel consumption and ultra-low emissions, it is ideal for factories, remote sites, gas stations, and power plants. The fully automatic control system ensures safe, unattended operation, while multiple enclosure options (open, silent, containerized) adapt to different working environments.

Specification

Key Structure:

1.CNG Engine:  High-efficiency gas engine with low fuel consumption and long service life
2.Alternator:  Brushless alternator with stable voltage output and high efficiency
3.Control Panel:  Digital controller for monitoring, protection, and automatic operation
4.Fuel System:  Special gas mixer and pressure regulator for stable CNG supply
5.Cooling System: Water-cooled radiator for continuous high-load operation
6.Optional ATS:  Automatic transfer switch for seamless backup power

Core Advantages

* Safety & Reliability:
Multi-layer safety interlock: high-energy ignition, electronic governor, knock monitoring, overspeed protection, low-pressure gas cutoff, high-temperature alarm, and abnormal lube-oil consumption detection—full coverage for stable operation.
* Clean & Eco-Friendly:

Full combustion, zero black smoke or dust; compliant with national standards and EU Stage IIIA; NOx as low as 250-500mg/Nm3; ideal for urban and environmentally sensitive deployments.
* High Efficiency & Energy Saving: 
35%-42% power generation efficiency; CHP model reaches >85% total energy utilization vs. ~60% for pure generation; waste heat recoverable for heating, cooling, or steam—maximum energy utilization.
* Flexible Adaptation: 
30kW-3600kW per unit, scalable to tens of MW; compatible with natural gas, biogas (CH4>=35%), associated gas, coalbed methane, refinery tail gas, and biomass gas; custom preprocessing available.

Applications:

Industrial Factories: Continuous power for manufacturing plants and workshops
Gas Stations & CNG Stations: On-site power for gas stations and remote fuel facilities
Remote Sites & Mining: Off-grid power for mining operations and construction sites
Biogas & Waste-to-Energy Projects: Power generation using clean natural gas or biogas
Commercial Buildings: Backup power for hotels, malls, and office buildings
Emergency Backup Power: Reliable backup for hospitals, data centers, and critical facilities
