Heavy fuel oil Diesel generator sets (HFO diesel generator), mostly in low-speed generator, the main operating costs are low, long-term continuous operation and reliable operation, long life expectancy, fast quick return on investment and low noise advantages. The disadvantage is the high investment for the construction.

The hfo diesel generator sets can be the best choice for power generation of uninterrupted power plants, large industrial and mining enterprises and regional power plants, large industrial and mining enterprises and the regional electricity.

Heavy machine advantages and disadvantages:

when compared the heavy fuel oil with diesel oil,  the hfo prices is much lower, more economical for use in continuous power generation.

Heavy fuel oil diesel generator machine durability, it has a long overhaul period, the shortest overhaul time is more than 10,000 hours before overhaul, the longest up to more than 40,000 hours before to be overhauled, and a longer service life, while the diesel engine at 7,000 hours is generally would need a major overhaul.
Heavy fuel oil diesel generator’s noise is low, but hfo diesel generator power plant need more site area for installation, and construction period is longer than diesel oil power plant
Heavy fuel oil diesel generator fuel consumption is low,but it's a one-time investment is large.
Heavy fuel oil diesel generator can bear heavy load and can continuous run at 90% or rate capacity, but requirement for O&M staffs skills are higher.

Heavy fuel oil diesel generator can run reliably and continuously with high availability, and can take full advantage of application of exhausted hot gas to generate power or use for cooling/heating, resulting in considerable economic benefits.
Heavy fuel oil and light oil power generation cost comparison:
1, oil prices: according to current market price of oil, 180 # heavy oil: 3000 yuan / ton; 0 # diesel oil: 4.05 yuan / liter.
2, fuel oil consumption: According to the Diesel Engine Performance exact statistics, burning heavy fuel per kilowatt of about 240 g; burning of diesel fuel per kWh 0.28 liters. (if for our MAN or Hyundai HFO set, the oil consumption is about 180g/kwh)
3, can be seen from the table on the right than the use of heavy fuel oil diesel power generation cost per kilowatt of about 0.418 Yuan.

item	HFO Diesel Genset in Chinese Yuan	Diesel Genset in Yuan
Oil consumption	0.72 (if for MAN or Hyundai engine, the oil cost is about 0.54)	1.134
Maintenance	0.03	0.03
Lube oil/consumable	0.02	0.036
Equipments depreciation	0.01	0.02
Management	0.02	0.01
Total cost	0.81	1.228

4, to calculate One 1000KW unit, with 90% load operation, 22 per day to run a small, generating 26 days a month, the monthly generation capacity: 520,000KWH or so. More profits from HFO set over diesel fuel oil power generation: 520,000kWh × 0.418 yuan / kWh = 217,300Yuan.

5. with the international and domestic energy price adjustment, the price of 0 # diesel oil will rise. More investors will work with lower energy consumption and lower emission, on. 180 # heavy fuel oil with its international label low-cost, high combustion value, ease of use will become as the preferred oil.
