Description
Technical field
The present invention is the project for entrusting colleges and universities to be researched and developed.The invention belongs to steam generation field more particularly to a kind of steamings
Boiler furnace belongs to the fields IPC code F22.
Background technology
Receive heat from stove and fluid is made to flow to high-order circuit referred to as " riser circuit " from low level, and receives heat
It measures and the circuit for making fluid flow to low level from a high position is referred to as " declining circuit ".One circuit is by a pipe or one group of pipe
Composition, this group of pipe are drawn from a common point, such as header or steamdrum, are terminated at and are similarly public as header or drum
Concurrent.
In the design of most of natural circulation boilers, the heat pipe for constituting evaporation section is typically for fluid flows upward, but
In more drum-type boilers, the downflow heated tube of steam-generating bank is quite different.In such boiler, downflow heated tube provides stove
Whole circular flows of interior and steam-generating bank part tedge.
On the one hand, the fluid of tedge is during upwards, usually stream-liquid two-phase flow, so that the stream in tedge
Body is liquid-vapor mixture, and the presence of stream-liquid two-phase flow makes the efficiency for affecting tedge heat absorption.
