Abstract

Método para eliminar los depósitos de lodo de un generador de vapor que incluye una placa de tubos en una extremidad inferior de un recipiente vertical y una multiplicidad de tubos y que se extienden hacia arriba a partir de ella, teniendo dicho recipiente un orificios de acceso encima de dicha placa de tubos, caracterizado porque una corriente en forma de chorro líquido se dirige tangencialmente hacia dicho recipiente (12) encima de dicha placa de tubos (34) con el objeto de crear una corriente circunferencial de líquido en la extremidad externa de dicho placa de tubos (34), y porque dicha corriente es aspirada y extraída de dicho recipiente por un aparato de aspiración (66,74) y, al mismo tiempo, una lanza (76) provista de orificios provista de orificios de salida de chorros de líquido (84) se desplaza a través de dichos tubos (38) encima de dicha placa de tubos (38) y hacia dicha corriente líquida circunferencial para lavar todos los depósitos desprendidos de las extremidades inferiores de los tubos (38) y contenidos en dicha corriente líquida circunferencial de modo que sean inmediatamente eliminados a través de dicho aparato de aspiración (66,74).
