Abstract
The utility model discloses a wall type reheater of a boiler. The wall type reheater of the boiler comprises a plurality of vertical pipelines arranged at the inner side of a water wall of the boiler and horizontal steam inlet pipes connected with the vertical pipelines. The horizontal steam inlet pipes are communicated with inlet collecting boxes. The vertical pipelines are communicated with outlet collecting boxes. Each horizontal steam inlet pipe is communicated with one vertical pipeline through a first horizontal extending pipe, an arc connecting pipe and a second horizontal extending pipe, wherein the first horizontal extending pipe, the arc connecting pipe and the second horizontal extending pipe are sequentially connected. According to the wall type reheater of the boiler, the high-temperature smoke vortex intensity in a combustion chamber of the boiler using the four corner combustion mode is reduced and the heat exchanging efficiency is high.
Description
Technical field
The utility model relates to a kind of boiler, relates in particular to a kind of wall type reheater of boiler.
Background technology
Thermal power plant is adopted boiler heating steam to drive steam turbine generator and is generated electricity, and is provided with water-cooling wall in boiler, and the inboard of upper furnace water-cooling wall (the namely inboard of the water-cooling wall of front side, top and both sides) is provided with wall type reheater.Traditional reheater concrete structure is as shown in Figure 1-2: comprise some be arranged on boiler water wall 5 ' on vertical pipeline 1 ' and with the horizontal steam inlet pipe 2 of vertical pipeline 1 ' directly be connected ', horizontal steam inlet pipe 2 ' with entrance header 3 ' be connected, vertical pipeline 1 ' with outlet header 4 ' be connected.Reheater can make the thermal efficiency of unit increase substantially, but when the non-full load operation of boiler, in reheater, vapor (steam) temperature may not reach designing requirement.And boiler coner firing mode commonly used is burnt, and, because the high-temperature flue gas after burning is that mode with vortex moves upward, causes the gentle Temperature of Working deviation of cigarette of boiler both sides all larger, affects the heat exchange performance of boiler integral body.
The utility model content
Technical problem to be solved in the utility model is: a kind of wall type reheater that can reduce high-temperature flue gas voorticity in boiler and the high boiler of heat exchange efficiency is provided.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of wall type reheater of boiler, comprise some horizontal steam inlet pipes that are arranged on the vertical pipeline of boiler water wall inboard and with vertical pipeline, are connected, horizontal steam inlet pipe is connected with the entrance header, vertical pipeline is connected with outlet header, and described horizontal steam inlet pipe probes into pipe, circular arc tube connector, the second level by the first level that connects successively and probes into to manage and be connected with vertical pipeline.
Described every several horizontal steam inlet pipes, the first level probe into pipe, circular arc tube connector and the second level and probe into Guan Weiyi and organize and be arranged on same perpendicular, the admission tube connector of horizontal steam inlet pipe pipe end by several different radians is connected with the water transport port of several diverse locations on the same cross section of entrance header respectively, and the second level probes into the pipe pipe end and is connected with vertical pipeline accordingly by the bend pipe of several different radians.
Described the second level probes into pipe and is arranged in the top of described horizontal steam inlet pipe.
Described circular arc tube connector pipe end to the distance of boiler water wall between 80cm-140cm.
The beneficial effects of the utility model are: because horizontal steam inlet pipe probes into pipe, circular arc tube connector, the second level by the first level that connects successively, probe into to manage and be connected with vertical pipeline, probe into the interior pipeloop of burner hearth resistance of vortex formation for flue gas, so the remitted its fury of vortex; Simultaneously, the area of heat exchange increases, and can effectively increase Radiant exothermicity, and heat exchange efficiency is high, improves the control characteristic of boiler.

The specific embodiment
, below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Fig. 3-6, a kind of wall type reheater of boiler, comprise the some vertical pipeline 2 of boiler water wall 1 inboard and horizontal steam inlet pipes 3 that are connected with vertical pipeline 2 of being arranged on, horizontal steam inlet pipe 3 is connected with entrance header 4, vertical pipeline 2 is connected with outlet header 5, and described horizontal steam inlet pipe 3 probes into pipe 6, circular arc tube connector 7, the second level by the first level that connects successively and probes into pipe 8 and be connected with vertical pipeline 2.The second level probes into pipe 8 and is positioned at the top of horizontal steam inlet pipe 3, and every three horizontal steam inlet pipes 3, the first levels probe into pipe 6, circular arc tube connector 7 and the second level and probe into pipe 8 and be one group and be arranged on same perpendicular, the admission tube connector 10 of horizontal steam inlet pipe 3 pipe ends by three different radians is connected with the water transport port of three diverse locations on the same cross section of entrance header 4 respectively, and the second level probes into pipe 8 pipe ends and is connected with vertical pipeline 2 accordingly by the bend pipe 9 of three different radians.Circular arc tube connector 7 pipe ends to the distance of boiler water wall 1 is 100cm.
Because the pipeloop that probes in burner hearth forms a resistance for the vortex of flue gas, so the remitted its fury of vortex causes both sides temperature deviation in boiler to reduce, according to putting into practice numerical value that its deviation reduces more than 10 ℃.In addition, the area increase due to heat exchange, can effectively increase Radiant exothermicity, and its heat exchange efficiency is higher, has improved the control characteristic of boiler.It is an especially effectively mode that the boiler that particularly for the reheater temperature, does not reach designing requirement undergoes technological transformation, and has improved the economy of unit.For the situation of superheater overtemperature, adopt after the reheater of this structure heat due to burner hearth to be absorbed a part by reheater more and also can reduce the spray water flux of superheater, can further improve the economy of unit.
