Natural Gas Generator Sets and Distributed Energy: Core Overview
Natural gas distributed energy is a highly efficient energy supply system that uses natural gas as fuel to simultaneously produce electricity, heat, cooling, and other energy forms at or near the point of use. Its core principle lies in the cascade utilization of energy: electricity is first generated by a gas-powered generator set, and then the waste heat produced during power generation is recovered for heating, cooling, or steam supply. This increases the comprehensive utilization rate of primary energy from around 40% in conventional methods to over 80%.
Core Equipment: Generator Set Comparison
| Characteristic | Gas Engine Generator Set | Gas Turbine Generator Set |
|---|---|---|
| Power Range | Several hundred kW to MW scale | Several MW to hundreds of MW scale |
| Key Features | High electrical efficiency, rapid start-up (~30 seconds), suitable for fast peaking | Compact structure, low emissions, high-grade waste heat suitable for high-pressure steam |
| Typical Applications | CCHP for buildings/small campuses, backup power | Regional energy stations for large campuses/industrial parks |
Core Advantages and Value
-
High Efficiency & Energy Saving: Comprehensive energy utilization rate exceeds 80%, far surpassing traditional separated supply methods.
