The invention relates to the field of superheaters, and particularly to a straight arrangement fixing device for a platen superheater, which includes a fixing frame and superheater tubes, wherein a plurality groups of fixing ring sleeves are uniformly arrayed in the middle part of the inner cavity of the fixing frame; the adjacent fixing ring sleeves are fixedly connected through a welded first connecting rod; the fixing ring sleeves are fixedly connected with the fixing frame through welded second connecting rods; mounting ring sleeves are mounted on outer side frame walls of the fixing ringsleeves in a sleeving manner; and buzzers are fixedly mounted on the outer sides of the mounting ring sleeves. In the invention, telescopic rods are cooperated with springs to effectively provide certain reserving spaces to the superheater tubes and avoid later expansion, and after the later expansion reaches to a certain range, the insides of the telescopic rods are pushed against pressure sensors to trigger an alarm, so that the straight arrangement fixing device has good functionality, and can effectively avoid the superheater tubes from emergent bursting.
Description
technical field [0001] The invention relates to the field of superheaters, in particular to an in-line fixing device for panel superheaters. Background technique [0002] The superheater is a part in the boiler that further heats the steam from the saturated temperature to the superheated temperature, also known as the steam superheater. The superheater can be divided into convection type, radiation type and semi-radiation type according to the heat transfer mode; according to the structural characteristics, it can be divided into snake-shaped tube type, screen type, wall type and wall-wrapped type. They all consist of several parallel pipes and inlet and outlet headers. In the prior art, the panel-type superheater is generally fixed by a fixing device, such as a tube row-type fixing device, which is finely connected by two buckled corrugated plates and a T-shaped fixing block. The corrugated plates include several arc-shaped plates, and each adjacent The connecting plate ...
