New Fuel-Control System Reduces Boiler Fuel-Usage by Two Percent
November 18, 2005
Nippon Yusen Kaisha (NYK) and its group company Nippon Steel Corporation have jointly developed a fuel-control system called ULTY to reduce the amount of fuel required in boiler systems. Experiments have revealed that installation of the new control system can reduce fuel usage by 2 percent.
The new control system works by applying a correction value calculated using a special formula to determine the exact amount of fuel required, which in turn prevents excessive use of fuel in boiler systems. An additional characteristic of the control system is that it can be installed directly into any type of boiler, without reconstructing the facility itself.
Experiments for the system were conducted at a 300-megawatt electric power station, a station that provides electricity for about 150,000 households. Results showed that fuel usage was reduced by approximately 2 percent. A power station of this scale consumes approximately 600,000 to 700,000 tons of coal annually. Installation of the new system will reduce fuel consumption by 12,000 to 14,000 tons per year.
The system has also proved its merit when used in coal-fueled boilers and heavy-oil-fueled boilers, both of which are easily affected by dirt in the fuel-transfer tubes.
NYK Line and its group companies continually strive to reduce energy consumption and hazardous-substance emission for protection of the environment.
