Embodiment Construction

[0042] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0043] In this article, if there is no special explanation, when it comes to formulas, " / " means division, and "×" and "*" mean multiplication.

[0044] further as figure 1 The aforementioned steam boiler includes an upper drum 1 and a lower drum 2 , and the ascending tube 3 and the downcomer 5 connect the upper drum 1 and the lower drum 2 . Water enters the downcomer 5 from the upper drum 1 . The water flows down in the downcomer and is collected in the lower drum 2 of the tube bundle. The riser 3 of the boiler is heated by the combustion of fuel in the combustion chamber 10 of the furnace. The heat absorbed by the riser 3 causes the liquid inside the tube to boil, thereby creating a two-phase mixture of water and steam. The two-phase mixture in the riser 3 reaches the upper drum 1 . The supercooled water released from the water supp...

Abstract

The invention provides a steam boiler. The steam boiler comprises an upper boiler barrel, a lower boiler barrel, rising pipes and falling pipes, wherein the rising pipes and the falling pipes are connected between the upper boiler barrel and the lower boiler barrel. The rising pipes are internally provided with flow stabilizers, and the multiple flow stabilizers are arranged in the same rising pipe; and the lengths of the flow stabilizers are constantly increased in the fluid flowing direction of the rising pipes. According to the flow stabilizer steam boiler of a novel structure, through length changing of the flow stabilizers, when steam-liquid two phase flowing exists in the rising pipes, heat transmission is reinforced; and meanwhile, 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...
