Abstract

The utility model relates to a jacket liner boiler. A jacket liner is added in a one-layer liner of a common boiler. The inner wall of the jacket liner forms a combustion chamber. The outer wall of the jacket liner and the one-layer boiler liner form a cyathiform flue as a second return stroke channel for fume. Therefore, the boiler becomes a three return stroke boiler with large heat transmission area, little steel consumption, good combustion conditions and high thermal efficiency. The utility model can be widely used for design, manufacture and technical innovation of a boiler shell type boiler.

Description

Chuck flue formula boiler
The utility model belongs to a kind of boiler, particularly a kind of boiler with chuck flue.
The flue of boiler all is an individual layer at present.The high-temperature flue gas that produces after fuel burns therein flows through the heat convection district that is made heat-transfer surface by smoke pipe bundle or festoon after flowing to first backhaul of other end formation flue gas from an end again, and the internal surface area of flue is the heat exchange area of boiler first backhaul.A kind ofly be called as the boiler that cigarette is returned at the center,, flow through tube bank heat convection district again after an end flows to the other end though the high-temperature flue gas in its flue returns again.Returning still of its flue gas carried out in the individual layer flue, and the long-pending area of total heat exchange of first, second backhaul still is the internal surface area of individual layer flue.And, return mobile flue gas and also can sneak into just from the fuel gas flow of burner ejection, make the boiler instability of catching fire, incomplete combustion, heat loss increases.
The purpose of this utility model is to provide the flue gas that a kind of second backhaul is flowed can't sneak into the fuel gas flow that has just sprayed from burner, thereby realizes the chuck flue formula boiler that three real backhauls are flowed.
The purpose of this utility model is achieved in that increases a chuck flue in the individual layer flue of plain cylindrical furnace, inwall by the chuck flue constitutes the combustion chamber, fuel is after the internal combustion of combustion chamber, the high-temperature flue gas that produces flows out from the shell and the common cup-shaped flue that constitutes of individual layer flue of chuck flue, enters tube bank heat convection district again.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Accompanying drawing 1 is a structural representation of the present utility model;
In the accompanying drawings, the chuck flue is by chuck inboard wall of furnace [16] and the common formation of chuck furnace outer wall [14].Chuck inboard wall of furnace [16] surrounds combustion chamber [2].Chuck furnace outer wall [14] constitutes cup-shaped flue [4] jointly with individual layer flue [8].Between chuck inboard wall of furnace [16] and chuck furnace outer wall [14], chuck [3] is arranged.The openend of chuck [3] is by front wallboard [15] sealing of boiler.The fuel and air mixture of burner [1] ejection burns in combustion chamber [2], and the high-temperature flue gas of generation flows to the rear end from chamber front end, finishes first backhaul and flows; Leaving combustion chamber [2] flows along second backhaul of cup-shaped flue [4] do again; Do the 3rd backhaul by smoke pipe bundle [13] again and flow, discharge from exhanst gas outlet [9] at last.Medium in the boiler circulates like this: cryogenic media enters boiler from medium import [7], after smoke pipe bundle [13], individual layer flue [8] heat absorption, enter communicating pipe [12] from taking over [11] again, openend by the chuck flue enters in the chuck [3] after the heat absorption again, enters upper boiler by last communicating pipe [5] again.Liquid state or gaseous state high-temperature medium that boiler produces are discharged for using from media outlet [6].[10] are blowoff valves among the figure.
The utility model makes flue gas realize that three real backhauls are mobile, and heat transfer area is big, and it is few to consume steel, and combustion conditions is good, and thermal efficiency height can extensively be suitable for manufacturing and designing and technological transformation of smaller hard flour pancake boiler.

Claims (2)

1, a kind of chuck flue formula boiler, constitute jointly by plain cylindrical furnace and chuck flue, it is characterized in that: increased a chuck flue in the individual layer flue of plain cylindrical furnace, the inwall of chuck flue constitutes the combustion chamber, the cup-shaped flue of the common formation of the outer wall of chuck flue and individual layer flue.
2, a kind of chuck flue formula boiler as claimed in claim 1 is characterized in that between chuck inboard wall of furnace and chuck furnace outer wall chuck being arranged, and the openend of chuck is by the front wallboard sealing of boiler.
