Abstract
The utility model 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 both ends straight tube passes perpendicularly through furnace wall and welded therewith, and the inner chamber of waterpipe type cooler communicates with stove hydrospace；The structure of waterpipe type cooler can also use the combination of the concentric circles endless tube and two sections straight tube at middle part, and concentric pipe takes 3 ~ 5, and its caliber is less than straight tube, and the upper and lower ends of all pipes with one heart 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 can reduce flame peak temperature, so as to reduce thermal NOXGeneration.
Description
Technical field
A kind of gas fired-boiler is the utility model is related to, cools more particularly to a kind of gas fired-boiler flue inner conduit formula and fills
Put.
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, amount is small
It is negligible, therefore, reduce NO in gas fired-boilerXDischarge mainly control thermal NOX.General principle is to reduce flame
Peak region ignition temperature, spray into water droplet in 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 blow 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 infinitely to 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 utility model discloses the cooling of gas fired-boiler flue inner conduit formula to fill
Put.
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
Both ends straight tube passes perpendicularly through furnace wall and stretches out 2 ~ 5mm of furnace wall, and is welded with furnace wall, 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 can also use 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 pipes with one heart 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 utility model are：First, stove water is full of in waterpipe type cooler all the time,
By the rising of free convection hot water, cold water enters from lower end, can effectively avoid the wall surface temperature of waterpipe type cooler too high；Second,
Waterpipe type cooler can quickly absorb flame heat regulating, flue flame peak region temperature be reduced, so as to reduce thermal NOXIt is raw
Into；Third, waterpipe type cooler has flow-disturbing and the effect of breaing up to flame, ectonexine flame can be promoted to mix, accelerate flame to dissipate
Heat；Fourth, waterpipe type cooler hot expansibility is good, damage caused by thermal expansion is avoided that, 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.
Embodiment
The utility model is further illustrated 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, it can also use the concentric circles endless tube at middle part and the knot of two sections straight tube
Close.During installation, it is slightly larger than waterpipe type cooler straight tube with lower wall surface perforate in axis vertical direction, aperture in the middle part of flue axis
Caliber；Waterpipe type cooler tilts certain angle and enters flue, and upper end straight tube is introduced into flue perforate, until waterpipe type cools
Device lower end can be vertically into flue perforate, and then both ends and furnace wall welding, the both ends straight length of waterpipe type cooler stretch out
Furnace wall 2-5mm.2 ~ 5 waterpipe type coolers can be set in the axial direction in the middle part of flue axis.
Be full of stove water all the time when gas fired-boiler is run, in waterpipe type cooler, by the rising of free convection hot water cold water from
Lower end enters, and can effectively avoid the wall surface temperature of waterpipe type cooler too high；Waterpipe type cooler can quickly absorb flame heat
Amount, flue flame peak region temperature is reduced, 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
Damage caused by exempting from thermal expansion, and can modularization setting.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
