摘要

Device for implementing a method for cleaning the heating surfaces in steam generators of power stations and heating stations, a pressure-medium hose being introduced into a pipe lane and in the heating surfaces to be cleaned, high-pressure water being sprayed onto the heating surfaces by means of spray nozzles and the spray-nozzle position being changed in relation to the heating surfaces, according to the main patent the pressure-medium hose being introduced into the pipe lane and the high-pressure water being sprayed in a pulse-compensated manner out of at least two opposite spray nozzle bores and the spray-nozzle position being varied from above the pipe lane by changing the length and/or position of the pressure-medium hose. The pressure-medium hose can be suspended in a pipe lane as a straight hose. The hose bears at least at its end a pulse-compensated spray nozzle, and a stabilising weight is also connected at the hose end. <IMAGE>
