1. What is the hourly gas consumption of the gas genset used in the project?
Answer: In the oilfield drilling rig market, there are various gas supply channels, fuel calorific values have certain differences, and load fluctuations are large. The gas genset load rate is between 20% and 80%, and the average power generation of the entire project is about 2.6-3kwh/Nm ³, generally 2.8kwh/Nm³;
Applied in fixed load projects such as wellbore gas recovery, the load rate is generally between 60% and 80%, and the actual average power generation during project operation is about 3.2-3.3 kWh/Nm ³; If the average load of the customer is 1000kW, the hourly gas consumption is 1000/3.3=300Nm ³/h;
2. Why can't the gas genset operate at 250kW gas genset for a long time? What is the recommended continuous operating power and why?
Answer: The maximum load capacity of the gas genset is 250kW, and the factory test is also conducted based on the 250kW electrical power. The continuous operating power range of the gas genset is 60% -80%, which is 150kW-200kW. Under this operating condition range, the gas genset has the best reliability, while also considering fuel economy and high power generation efficiency. If the load intensity of the gas genset is high when operating at 250kW for a long time, the time for medium and major repairs of the gas genset will be significantly shortened. Recommend customers to use it under optimal load conditions.
3. Under what operating conditions does the 500kw gas generator set operate with the best efficiency?
Answer: The optimal operating efficiency point for the gas genset is at 70% -80% load point. At the load point of 70% -100%, the mechanical efficiency (professional description: effective thermal efficiency of the engine) is basically the same, and the generator has the highest power generation efficiency at the load point of 70% -80%. Therefore, the comprehensive optimal operating efficiency point is 70% -80% load. The standard natural gas power generation per cubic meter at this operating point is above 3.4 kWh, and using a 300kW engine produces around 3.6 kWh.
