Apart from the fuel consumption and the maintenance costs of a gas engine, the average lubricant consumption is a key factor affecting the TCO (total cost of ownership) of a gas genset. Recent measurements, field tests, and further development of the model series show that MWM has succeeded in reducing the lubricant consumption of the gas engines.

 

Gas engine	Gas type	Service category	Lubricant consumption
TCG 2016	Natural gas	400 / 600 / 800 kWel	0.20 g/kWh
TCG 2016	Natural gas	515 kWel	0.10 g/kWh
TCG 2016	Biogas	400 / 600 / 800 kWel	0.10 g/kWh
TCG 2020	Natural gas	1000 / 1200 / 1560 / 2000 kWel	0.15 g/kWh
TCG 2020	Biogas	1200 / 1560 / 2000 kWel	0.15 g/kWh
TCG 2032	Natural gas	3333 / 4300 / 3000 / 4000 kWel	0.20 g/kWh
TCG 2032	Biogas	3770 / 3510 kWel	0.20 g/kWh
TCG 2032B	Natural gas	4500 / 4050 kWel	0.20 g/kWh

 

Previous values:

• TCG 2016: 0.2 g/kWh
• TCG 2020: 0.2 g/kWh
• TCG 2032: 0.3 g/kWh

 

Reduced Operating Costs of CHP Plants

The main advantage for the customer is the reduction of the oil consumption and the associated financial savings. For example, the lubricant consumption of the MWM TCG 2032 gas engine series has been reduced by 0.1 g/kWh (from 0.3 g/kWh to 0.2 g/kWh). Based on an electrical output of 4,500 kW_el the operator of an MWM combined heat and power (CHP) plant thus saves 450 g of lubricant an hour. Assuming 8,000 operating hours a year, the lubricant savings total 3,600 kg. Expressed in volume and hard currency, this means a significant reduction of operating costs.
