Abstract
The invention discloses gas fired-boiler flue inner conduit formula heat sink, including flue and waterpipe type cooler, it is characterised in that：The structure of waterpipe type cooler includes the spiral coil and two sections straight tube at middle part, respectively accounts for 1/3 length, is vertically arranged in flue, and its two ends straight tube passes perpendicularly through furnace wall and welds therewith, and the inner chamber of waterpipe type cooler communicates with stove hydrospace；The structure of waterpipe type cooler also can take 3 ~ 5 using the combination of the concentric circles endless tube and two sections straight tube at middle part, concentric pipe, and its caliber is less than straight tube, and the upper and lower ends of all concentric pipes are connected to two sections of straight tubes；2 ~ 5 waterpipe type coolers are set in the axial direction in the middle part of flue axis.During operation, stove water is full of in waterpipe type cooler all the time, and quickly absorbs flue flame heat, cold water enters from lower end by the rising of free convection hot water.Waterpipe type cooler has flow-disturbing and the effect of breaing up to flame, while flame peak temperature can be reduced, so as to reduce thermal NOXGeneration.
Description
Technical field
The present invention relates to a kind of gas fired-boiler, more particularly to a kind of gas fired-boiler flue inner conduit formula heat sink.
Background technology
Nitrogen oxides is NOXA kind of common atmosphere pollution to form photochemical fog, damage the ozone layer, in recent years with
Increasing environmental pollution, country continues to increase environmental requirement.NOXType be broadly divided into three kinds：It is fuel type, heating power type, quick
Type.For existing gas furnace, fuel type NOXControl problem is resolved, Quick-type NOXWith thermal NOXCompare, measure small
It is negligible, therefore, reduce NO in gas fired-boilerXDischarge be mainly control thermal NOX.General principle is to reduce flame
Spray into water droplet in peak region ignition temperature, the oriented flue of method of use or steam, flue internal welding be connected to the logical straight tube of current,
Expand flue area and to flue internal classification air-supply etc..Water droplet or steam penetrating flue implementation method difficulty are larger, and straight tube is heated
Limited area and thermal expansivity is poor, flue area is limited by boiler specification and cost can not infinitely be increased, and air stage feeding needs one
A whole set of complete device.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the invention discloses gas fired-boiler flue inner conduit formula heat sink.
Gas fired-boiler flue inner conduit formula heat sink, including flue and waterpipe type cooler, it is characterised in that：Waterpipe type
The structure of cooler includes the spiral coil and two sections straight tube at middle part, respectively accounts for 1/3 length, is vertically arranged in flue, its
Two ends straight tube passes perpendicularly through furnace wall and stretches out 2 ~ 5mm of furnace wall, and with furnace wall welding, the inner chamber of waterpipe type cooler and Lu Shui
Space communicates, and sets 2 ~ 5 waterpipe type coolers in the axial direction in the middle part of flue axis.
The structure of waterpipe type cooler also can be using the combination of the concentric circles endless tube and two sections straight tube at middle part, concentric circles
Pipe takes 3 ~ 5, and its caliber is less than straight tube, and the upper and lower ends of all concentric pipes are connected to two sections of straight tubes.
The material of various waterpipe type coolers will select heat resisting steel.
Compared with prior art, the beneficial effects of the invention are as follows：One is all the time full of stove water in waterpipe type cooler, by certainly
Right countercurrent hot-water rises and cold water enters from lower end, and the wall surface temperature that can be prevented effectively from waterpipe type cooler is too high；Two is water pipe
Formula cooler can quickly absorb flame heat regulating, flue flame peak region temperature be reduced, so as to reduce thermal NOXGeneration；
Three is that waterpipe type cooler has flow-disturbing and the effect of breaing up to flame, and ectonexine flame can be promoted to mix, and accelerates flame radiating；
Four is that waterpipe type cooler hot expansibility is good, is avoided that the damage that thermal expansion is caused, and can modularization setting.
Brief description of the drawings
Fig. 1 is gas fired-boiler flue inner conduit formula heat sink profile（Water pipe sets two groups）；
Fig. 2 is Section A-A top view（Waterpipe type cooler is spiral coil）；
Fig. 3 is Section A-A top view（Waterpipe type cooler is concentric circles endless tube）；
Reference：1- flues；2- waterpipe type coolers.
Specific embodiment
The present invention is further described below in conjunction with the accompanying drawings.
Gas fired-boiler flue inner conduit formula heat sink includes flue and waterpipe type cooler, the structure of waterpipe type cooler
Spiral coil and two sections straight tube including middle part, also can be using the concentric circles endless tube at middle part and the knot of two sections straight tube
Close.During installation, with lower wall surface perforate in axis vertical direction in the middle part of flue axis, aperture is slightly larger than waterpipe type cooler straight tube
Caliber；Waterpipe type cooler inclines certain angle and enters flue, and upper end straight tube is introduced into flue perforate, until waterpipe type cooling
Device lower end can be stretched out vertically into flue perforate, then two ends and furnace wall welding, the two ends straight length of waterpipe type cooler
Furnace wall 2-5mm.2 ~ 5 waterpipe type coolers can be set in the axial direction in the middle part of flue axis.
When gas fired-boiler runs, stove water is full of in waterpipe type cooler all the time, by free convection hot water rise and cold water from
Lower end enters, and the wall surface temperature that can be prevented effectively from waterpipe type cooler is too high；Waterpipe type cooler can quickly absorb flame heat
Amount, reduces flue flame peak region temperature, so as to reduce thermal NOXGeneration；Waterpipe type cooler has flow-disturbing to flame
With the effect of breaing up, ectonexine flame can be promoted to mix, accelerate flame radiating；Waterpipe type cooler hot expansibility is good, can keep away
Exempt from the damage that thermal expansion is caused, and can modularization setting.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in essence of the invention
Within god and principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
