Steam boiler provided with three boiler cylinders

Abstract

The invention provides a steam boiler provided with three boiler cylinders. The steam boiler provided with the three boiler cylinders comprises the first boiler cylinder, the second boiler cylinder and the third boiler cylinder, wherein the first boiler cylinder is located on the upper portion, the second boiler cylinder is located in the middle, and the third boiler cylinder is located on the lower portion; and the first boiler cylinder and the second boiler cylinder are connected through a first ascending pipe and a descending pipe, the second boiler cylinder and the third boiler cylinder are connected through the descending pipe, and the third boiler cylinder and the first boiler cylinder are connected through a second ascending pipe. According to the steam boiler provided with the three boiler cylinders, the three boiler cylinders are arranged so that all heat can be sufficiently used, heat transfer is enhanced, and the heat utilization rate is increased.

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...

AI Technical Summary

Problems solved by technology

The impact phenomenon will cause large noise vibration and mechanical shock, causing damage to the equipment

[0006] In addition, during the operation of the boiler, waste heat such as flue gas cannot be well utilized, and indirect utilization methods are generally used, such as through gas-saving or air preheaters, which will cause waste heat waste

[0007] In view of the above problems, the present invention improves on the basis of the previous invention, and provides a new steam boiler, thereby solving the problem of low heat absorption efficiency of the rising tube
