Steam generator with current stabilizers

Abstract

The invention relates to a steam generator which comprises an upper boiler barrel, a lower boiler barrel, rising pipes and falling pipes, and the rising pipes and the falling pipes are connected between the upper boiler barrel and the lower boiler barrel. Current stabilizers are arranged in the rising pipes, multiple current stabilizers are arranged in one rising pipe, and the lengths of the current stabilizers are gradually increased in the fluid flowing directions of the rising pipes. The steam generator with the current stabilizers of new structures is provided, the lengths of the current stabilizers are changed, when steam-liquid two-phase flow exists in the rising pipe, heat transfer is strengthened, vibration of the rising pipes is weakened, and the noise level is reduced.

Description

technical field [0001] The present invention is a project commissioned by colleges and universities to carry out research and development. The invention belongs to the field of steam generation, in particular to a steam boiler, and belongs to the field of IPC classification number F22. Background technique [0002] The circuit that receives heat from the furnace and makes the fluid flow from a low level to a high level is called an "ascending loop", while the circuit that receives heat and makes a fluid flow from a high level to a low level is called a "falling loop". A circuit consists of a pipe or a group of pipes leading from a common point, such as a header or steam drum, and terminating at a common point, also a header or drum. [0003] In most natural circulation boiler designs, the heated tubes making up the evaporating section generally provide upward flow, but in multi-drum boilers, the descending heated tubes of the evaporator bundle do not. In this type of boile...

Problems solved by technology

However, it was found during the operation of this device that the space A formed between the three pipes is relatively small because the pipes are tightly combined, because the space A is formed by the convex arc of the three pipes, so most of the space A Narrowness will make it difficult for the fluid to enter and pass through, resulting in a short circuit of the fluid, which affects the heat tran
