Fossil-fuled power plant as defined as coal, gas or oil-fueled power plants that are equipped with a flue gas desulforization plant. Coal-fired power plant are often used as base load or medium load plants. The pump seal run continuously. Gas and oil fired plants are generally designed to operate as peaking power plants, and they can also be used for voltage balancing when renewable (solar or windy) generation systems are on the grid. Seals are these plants are often exposed to highly fluctuating thermal and mechanical stress. Machine reliability and low susceptibility to failure are the crucial criteria in all of these applications. The machinery must be rugged enough to withstand high pressure, temperature and sliding velocities. The machinery also has to deal with different media such as river, sea or ultra pure water in feed pumps and cooling circuits. Sharpe LTJ, LBJ series mechanical seals are utilized in cooling water, condensate, main feed and suspension pumps. Download above attachment brochure for seal size detail.
