Questions and Answers:
I suggest 16H35/40X4,it’s enough? the engine model that can used see following,
A. We are agree with 16H35/40GV-50 Hz x 4 �Please send me an offer for thoose .
You mean the exhaust steam from our gas generator? yes, we can offer turbine for you to improve the efficiency.
A. Exhaust gas from your gas generator. We suppose to produce low pressure steam (about 12 bar, 190 °C) from exhaust heat by using waste heat exchanger and use that steam for power generation by a LP steam turbine. Please send me an offer for a convenient turbine too.
1)Where will be the location of the plant and the project name?
A. City: East; 40.11 North ; Project name:
2)These power plant will supply power to steel or other metals melting, chemical industry or mains supply for city?
A. Will supply the national grid.
3)This power plant is going to tender from your client or already in your hands?
A. No tender! Already in our hands, but some competitors with prices about 500 $/kW.
4), Is there any other competitors with you? What do you need us to support you to get the order except technical?
A. Yes, Waertsilla, MWM are the main competitors. Not only the investment cost will be determinant, the operating cost is also very important. Please , let me know the data’s like, NG-consumption per kWh electricity and the total efficiency of the plant for offered gas generators.
Q：We suppose to produce low pressure steam (about 12 bar, 190 °C) from exhaust heat by using waste heat exchanger and use that steam for power generation by a LP steam turbine. Please send me an offer for a convenient turbine too.
A.The steam from exhaust heat by using waste heat exchanger is not enough to drive turbine for power generation, just can be used for heating the mineral oil you have said before.
Q：let me know the data’s like, NG-consumption per kWh electricity and the total efficiency of the plant for offered gas generators.
A.NG-consumption per kWh electricity is 162g and the Brake Thermal efficiency of the engine is 44.6%
2MW gas engine generator with cogenerating system
1- what is the efficiency of gas turbine when we use natural gas,
A. The total efficiency of the plant is 49.5%
2- what is the efficiency of gas turbine and cogenerating
A. The steam from exhaust heat by using waste heat exchanger is not enough to drive turbine for power generation
3- please inform me the total natural gas consumption per hour .
A. NG-consumption per kWh electricity is 157g ,so the Total natural gas consumption for 2MW is about 314000g per hour.
4- how many hours you will guarantee it
A. One year after delivery.
5. they are willing to pay 20% of total amount to bank to get loan but it take some time. so if you provide the loan from chinese bank they can visit you and close the deal immediately
A: we need at least 30% of the employer's own financing or equity, among which we can offer 5-10%, you if your employer has 20% of the equity, and then he can let his bank or bank syndicate issue our bank financing guarantee, and buy our Sinosure insurance company premium, it is possible that our bank will offer financing of 70% of the EPC price.
6. PERFORMANCE DATA AT DESIGN AMBIENT CONDITION
- Gross Output AT Generator Terminal : 8381kW/Unit
- Fuel consumption at Generator Terminal : 1,758.0 Nm3/h
(Tolerance +5%, Load 100%, 50 Hz, PF = 0.8
Fuel gas LCV = 49138 kJ/kg, Density = 0.80558 kg/Nm3)
But local NG specifications are different
LCV : 8.250 kcal/Nm3
Density: 0,67 kg/Nm3
How are than the performance data’s?
A: FUEL GAS FOR GAS ENGINE
For continuous operation without reduction in the rated output, the fuel gas has to fulfill the below mentioned quality requirements.
In order to avoid operation problems like derating, corrosion, wear, lube oil contamination etc. the fuel gas composition must be submitted to the engine manufacturer.
Fuel Gas Specification
- Lower Calorific Value (LCV) : Min. 36 MJ/Nm3
- Methane Number (MN) : Min. 73
- Particles or solids at engine inlet : Max. 5 ㎛
- Particles or solids at engine inlet : 50 mg/Nm3
- Hydrogen sulphide content (H2S) : 30 mg/Nm3
- Gas inlet temperature : 0 - 60 Celsius Degree
