What Is an Industrial Exhaust Gas Generator?
An Industrial Exhaust Gas Generator is a specialized power generation system that uses industrial waste gas as fuel. Unlike conventional natural gas or diesel gensets, this generator runs on low-calorific, unstable, and mixed-component industrial gas streams. With a dedicated gas-air mixing system, turbocharging, and safety control features, the unit ensures stable combustion and high efficiency even under fluctuating gas conditions.
Typical Waste Gas Sources
Key Advantages of the 250kW Industrial Exhaust Gas Generator
Waste-to-Energy Efficiency — Converts low-value industrial exhaust gas into electricity, lowering energy cost dramatically.
Lower Fuel & Emission Costs — Reduces waste gas treatment, flaring, and emission penalty expenses.
Wide Gas Adaptability — Specially engineered to handle unstable gas composition and pressure variations.
High Operational Stability — Suitable for 24/7 industrial operation with advanced control, monitoring, and safety protection.
Environmental Friendly — Cuts CO₂, CO, NOx and particulate emission versus direct discharge or flaring.
Modular & Easy to Install — Compact 250kW module perfect for medium industrial plants or distributed energy stations.
Introduction to Technical Features
Turbocharging and shunt Intake technology：
Avoiding the generation of mixed gas, the gas and air enters the cylinder isolated with no contact. At the same time, the exhaust enery from the generator will be used for turbocharing the gas and air respectively. It realizes the improvement of intake and the synchronous improvement of operation power and volume power and ensures safety operation at the same time.
From 2018 till now, the safe stayale running time is more than 30000 hours. The measured electric efficiency is more than 40% in practice - 1m3 exhaust gas generates one kilowatt-hour of electricity.
There is no carbon monoxide leakage, no backfire and flash explosion, and the genset runs smoothly. Self consumption rate is less than 2%. The operation control of the genset is automatically adjusted with the change of gas.

How the System Works
The 250kW Industrial Exhaust Gas Generator adopts a specially designed gas-air mixing system, turbocharged combustion process, and engine control unit (ECU) to stabilize combustion.
Even low calorific value gas streams can be efficiently used for power generation.
Core Process
Exhaust gas enters gas pretreatment (dehumidifying, filtering, pressure-regulating).
Turbocharger increases the air intake pressure and enhances combustion.
Gas-air mixer forms a stable combustion mixture.
Engine converts combustion energy into shaft power.
Generator outputs stable 400V/50–60Hz electricity.
(Optional) Heat recovery unit provides hot water/steam for industrial use.
