Abstract: Through the installation of online cleaning robot instead of the original use of rubber ball cleaning system,the on-line cleaning of condenser cooling pipe is realized. Experiments have proved that on line cleaning technology, improved the cleanliness of condenser,turbine back pressure reduced,finally achieve the purpose of reducing coal consumption. And provide some reference for the economic operation of the unit.
