Abstract
A steam boiler liquid separator having a plurality of liquid separator segments connected together to form a shaft disposed inside a pipe section, with swirl vanes disposed around the shaft. The liquid separator segments each include a shaft segment connected to a pipe segment by a swirl vane such that the shaft segment is disposed radially inward from the pipe segment.
Claims14
A steam boiler liquid separator for a steam boiler through which steam flows vertically, comprising:
- a pipe section;
- a shaft in the pipe section;
- a shaft segment holder;
- a plurality of swirl vanes arranged about the shaft in the pipe section, wherein each swirl vane is connected to the pipe section, wherein the swirl vanes are shaped such that a rotational movement is imparted to a flow of steam through the pipe section in addition to a longitudinal movement through the pipe section;
- wherein the pipe section has a plurality of pipe segments and the shaft has a plurality of shaft segments;
- wherein each swirl vane is connected to a pipe segment and to a shaft segment to form a liquid separator segment;
- wherein the shaft segments are attached positively and detachably to the shaft segment holder by a positive connection;
- and
- wherein the shaft segments are held in position by the positive connection;
- wherein a first closure element is connected to a first end face of the shaft segment holder and a second closure element is connected to a second end face of the shaft segment holder;
- wherein the first and second closure elements have circular grooves with open sides facing the first and second end faces, respectively;
- and
- wherein radially extending groove walls of the circular grooves engage axial ends of the shaft segments.

A method for producing a steam boiler liquid separator, comprising:
- providing a plurality of liquid separator segments, wherein each liquid separator segment comprises a swirl vane connected to a pipe segment and to a shaft segment;
- providing a shaft segment holder;
- providing first and second closure elements;
- connecting the first closure element to the shaft segment holder;
- positively and detachably connecting the shaft segments of the liquid separator segments to the shaft segment holder such that the shaft segments are disposed adjacent to each other around a circumference of the shaft segment holder such that a pipe section is formed by the pipe segments and a shaft is formed by the shaft segments in the pipe section and such that the swirl vanes are arranged around the shaft in the pipe section and are shaped such that a rotational movement is imparted to a flow of steam through the pipe section in addition to a longitudinal movement through the pipe section;
- and
- connecting the second closure element to the shaft segment holder such that axial positions of the shaft segments between the first closure element and the second closure element are fixed.
