Natural Gas Engine and GenSet

On the basis of introducing the international advance technical diesel engine from Deutz AG, Germany, content the inside and outside market requirement of using the clean source of power, developed high speed, large power gas engine, generating sets and other power equipment. The power of generating sets is from 150kW to 1500kW, the grade of volage cover the normal 220V to high 10.5kV, gas widely used in various areas. The generating sets have various models, equipped the control system with international advance gas engine and the brushless generator, its performance can be reached international advance level.

Gas using

♦ Natural gas

♦ Mine gas, miscellaneous biogases, landfill gas

♦ Coke-oven gas, blast furnace gas, the tail gas of refining

The basic request of gas

♦ No liquid water and oil

♦ The content of sulfureted hydrogen volume not more than 0.15

♦ The gas pressure not less than 5 kPa

♦ [ma/m³ CH₄]<10, (um)3-10

The system of power station

        The system of gas power station mainly includes gas Gensets and other equipment as follow:

♦ The system of supplying gas and separating the harmful impurity(e.g. dehydration, desulphurization, catching coke etc,)

♦ Low concentration gas safety transport

♦ Outside cycle cooling system (open-type cooling Gensets)

♦ Power station ground, engine room, Gensets base

♦ Flame penetration guard of concentration gas

♦ Remaining heat recovery system (select it according to the function of power plant)

♦ High, low voltage control room, transfer and change wire circuit.

♦ Using the expendable-part stock and the basic living facility of watch keeper

The alternative cooling system scheme of power station

♦ Open-type cycle cooling system

     Mainly apply to the area with enough fountain and water quality in preferable condition. It has a nice cooling effect, no infection with the environment temperature. But the cooling water of inside cycle needs softening treatment.

♦ Close cycle cooling system

     Mainly apply to the area with lacking fountain, the gensets equipped with complete double cycle system. It needn't add the outside pipe, but the cooling effect is liable to effect by the environment temerature.

Main technical datasheet of gensets	The Gensets equipped with Siemens generator, self-excitation, invariable excitation. Self-heat abstraction, protection level: IP22/IP23, insulation level: F
Remark: 1. The rated condition of Gensets power according to the standard environment condition marked in DIN ISO3046: atmospheric pressure 100kPa, air temperature 25 deg C, air relative humidity 30%. 2. Fuel consumption is calculated on the basis of  clean natural gas, the different gas composition will affect the Gensets power.

Characteristic of Gensets

♦ The gen-sets equipped with V 8, 12, 16 cylinders, engines with the update gas engine technology in the world.

♦ The central arrangement for industrial spark plug, has the performance good spark plug seat cooling system and increase of service life. Each cylinder has one ignition coil, it is convenient for maintenance.

♦ The microprocessor controls the high-tension ignition system and makes the adaptability of the internal combustion engine and the control more perfect.

♦ Automatically main net voltage tracking adjustment with U.S. Basler digital technology

♦ The entire electric control system carries on the electronic control and the monitor to Gensets.

The advantage of power station

♦ Abundant gas resource, sustainable using

♦ May take as CDM project, bring into Nation or International plan of reducing emission

♦ Gensets with high removability, apply to the different digging for using

♦ May use the remaining heat of power generation, replace of supply heat in some certain area

♦ Low cost, fast invest recovery

Main Technical Index

♦ When content of coal bed gas no less than 20%, it could be primarily treated for power generation

♦ When content of coal bed gas no less than 5%, it could be specially treated for power generation

♦ Low fuel gas consumption, pure gas of each cube could be powering generation above 3.5KWh

♦ The power generation of Gensets with high thermal efficiency, can reach above 38%

♦ Compositively use remaining heat, thermal efficiency can reach 65%-80%

Marsh gas, gas of landfill of refuse generation system

Using the gas produced from production process of chemical industry, like the city sewage treatment, landfill of refuse field, the large-scale breeding farm, brews and so on. Adopts the single gensets or parallel operation to transforms the waste gas into electrical power and send to enterprise interior electrical network. It will reduces the waste gas discharges to the atmosphere and also saved the considerable energy disbursement for the enterprise.

Hot, cold and the electricity, tri-link supply system

Hot, cold and the electricity, this tri-link supply system is new generation of energy application system technology, it has represent the direction of energy use of the city as  to the clean non-pollution development. Main application is suitable to apply the place which demands stable hot, cold and the power load, like office, high-quality office, apartment, hotel, hospital and so on. This system use for user's group security power supply, it will not only save the investment cost of boiler to burnt coal, fuel gas hot water, but also effectively solve the unbalance of requirements of electric power for hot and cooling between the summer and the winter, the system's cleanly exhaust will reduce the emission of greenhouse gasses. It meets the requirement of "the Kyoto protocol" and rise the comprehensive utilization ratio of energy sources.
