A Yuchai 12VC 1500KW high-voltage containerized diesel generator set was delivered to a coal preparation (washing) plant in Baotou, Inner Mongolia, to serve as dedicated standby power for the coal processing line.
1. Background: Baotou and the Coal Preparation Plant
Baotou, in Inner Mongolia, is a major coal and coking base in northern China. Coal preparation plants wash, screen and grade raw coal before it reaches power plants and steel mills; their belt conveyors, vibrating screens, pumps and dewatering equipment cannot simply stop when the grid drops - an unplanned stoppage causes material backlog and costly restart procedures. A reliable backup power source is therefore a standard requirement for continuous-operation plants of this type.
2. Why One 1500KW Container Set
The plant needed standby capacity that could be installed quickly with minimum civil works. A single 1500KW containerized unit, dropped on a prepared concrete pad and cabled to the plant low-voltage bus, gives selective backup for the critical "must-run" loads (screens, pumps, conveyors) during an outage - the normal, cost-effective approach for a continuous processing line, rather than backing the whole plant.
3. Key Technical Specifications
· Engine: Yuchai 12VC, 12-cylinder V-type diesel
· Rated Power: 1500 kW
· Configuration: integrated weatherproof container (plug-and-run)
· Voltage: high-voltage direct connection, no separate step-up transformer
· Rated Speed: 1500 r/min
· Rated Frequency: 50 Hz
· Control: automatic start on mains failure (ATS-ready), AVR voltage regulation
4. Operational Value Since Commissioning
On a grid interruption, the set auto-starts and carries the screening and conveying load until utility power returns - protecting the production line from material backlog and unscheduled downtime. The containerized, weatherproof design also shields the engine from Inner Mongolia's dusty, cold climate with minimal on-site build.
5. Frequently Asked Questions (FAQ)
Q: Why a containerized rather than open skid unit?
A: A container encloses the engine, radiator, exhaust and control panel in one weatherproof, noise-attenuated package, cutting on-site build time and protecting the set in dusty, cold conditions.
Q: Is 1500KW enough for a coal washing plant?
A: It is sized for the critical "must-run" loads (screens, pumps, conveyors) during an outage, not the whole plant - the standard selective-backup approach for continuous processing lines.
Q: Does it work in cold winters?
A: Yes - the container is heated and the engine uses cold-climate starting aids, so it can crank and carry load in northern China winter conditions.
