 CNG Generators
CNG Generators
  • ※ No Exhaust Gas,Start quickly in cold region,Lower running cost
    ※ Gas consumption: less than 0.28cbm/kWh 
    ※ Low operation cost of nature gas generator
    ※ High profit of nature gas generator: low operation&maintenance cost, supply of electricity and thermal power at the same time.
    ※ Long designed overhaul term: 25000 ~ 30000 hours
    ※ Electronic Air/Gas mixer. The mixer guarantees optimum air-fuel ratio, improves thermal efficiency, reduces NOx emission. Unique air-fuel ratio adjusting system suits 30% ~ 90% methane density.

► Applicable Fuels of Natural Gas Scope
Methane Based Gas, mainly including natural gas (CNG, LNG, PNG), Oilfield Assoicated Gas, Coalmine Gas, Coalbed Gas,  Coal Well Gas, Shales Gas and so on.

♦ Compressed natural gas: CNG is methane stored under high pressure in a gaseous form, making it lighter than air. It is safer than gasoline and diesel because it's nontoxic, and disperses quickly.

♦ Liquefied natural gas: LNG is methane cryogenically cooled to a liquid form, reducing its volume for ease in storage and transport. LNG provides fleet managers with the ability to store more fuel with less tank weight, thus creating an efficient and cost-saving fueling solution for heavy-duty trucking, marine, and rail fleets.

♦ Oilfield Gas: other named associated petroleum gas (APG), or associated gas, is a form of natural gas which is found with deposits of petroleum, either dissolved in the oil or as a free "gas cap" above the oil in the reservoir.

♦ Coalbed methane gas: coal-bed methane (CBM), coalbed gas, coal seam gas or coal-mine methane, is a form of natural gas extracted from coal beds. In recent decades it has become an important source of energy in United States, Canada, Australia, and other countries.

♦ Shale Gas: shale gas a kind of natural gas that is found trapped within shale formations.Shale gas has become an increasingly important source of natural gas in the United States since the start of this century, and interest has spread to potential gas shales in the rest of the world. In 2000 shale gas provided only 1% of U.S. natural gas production; by 2010 it was over 20% and the U.S. government's Energy Information Administration predicts that by 2035, 46% of the United States' natural gas supply will come from shale gas.
