Question 1

What is a gas generator set and how does it work?

Accepted Answer

A gas generator set converts the chemical energy of fuel gas into electrical energy. The gas mixes with compressed air in the combustion chamber and ignites, producing high-temperature high-pressure gas that drives turbine blades or pistons to generate electricity. HUAQUAN gas generator sets are available from 20kW to 1200kW.

Question 2

What are the fuel requirements for a gas generator?

Accepted Answer

Natural gas: methane content >=70%, hydrogen sulfide <=20mg/Nm3, moisture <=40g/Nm3, inlet pressure 80-200kPa. Biogas: methane >=40%, pressure 3-100kPa. Corrosive components must be pre-treated to safe limits to avoid engine damage.

Question 3

What is the difference between a gas generator and a diesel generator?

Accepted Answer

Gas generator: lower fuel cost, cleaner emissions, longer engine life, but requires stable gas supply and higher initial investment. Diesel generator: higher fuel cost, louder, but more portable and faster startup. Choose based on fuel availability and application.

Question 4

Can a gas generator run on biogas from an anaerobic digester?

Accepted Answer

Yes. HUAQUAN gas generators run on biogas with methane >=40%. System includes gas treatment (desulfurization, dehydration) before entering engine. Typical for livestock farms, wastewater treatment plants, landfill sites.

Question 5

How much does a gas generator set cost compared to diesel?

Accepted Answer

Higher upfront cost (1.5-2x diesel) but 30-60% lower fuel cost. For continuous operation >2000h/year, ROI achieved within 2-4 years. HUAQUAN provides TCO analysis.

Question 6

What emissions standards do HUAQUAN gas generators meet?

Accepted Answer

Comply with EPA Tier 2/3, EU Stage IIIA, and China GB20891. Gas generators produce significantly lower NOx, PM, and CO emissions vs diesel generators.
