Fossil fuel power station eat the fish regularly. The largest source of mercury contamination in the United States is coal-fueled power plant emissions. Several methods exist to improve the efficiency of fossil fuel power plants. A frequently used and cost-efficient method is to convert a plant to run on a different fuel. This includes conversions of coal power plants to biomass or waste and conversions of natural gas power plants to biogas. Conversions of coal powered power plants to waste-fired power plants have an extra benefit in that they can reduce landfilling. In addition, waste-fired power plants can be equipped with material recovery, which
Fuel viscosity control Fuel viscosity control Fuel viscosity control is a technique to control viscosity and temperature of fuel oil (FO) for efficient combustion in diesel engines of motor vessels and generators of oil-fired power plants. Fuel oil's viscosity strongly depends on the temperature, the higher is the temperature the lower is the viscosity. For optimal combustion the viscosity of the fuel should be in the range of 10–20cSt. To maintain this value a combination of viscometer, PID controller and heater is used. Viscometer measures the actual viscosity of the fuel, this value is compared with the set point in the controller and
