Abstract

The utility model relates to a novel double-wing heat flow meter, which comprises a heat conduction part equipped in the outboard of a water wall tube. At least two thermocouples are installed in the said heat conduction part which has two wings attached with the two neighboring water wall tubes. Compared with the prior arts, the utility model has the following advantages: after a hole is made in the water wall tube fin, the heat flow meter is installed in the outboard of perforated part which makes one wing of the heat flow meter directly receive the heat transfer (radiation, convection) from high-temperature smoke inside an oven. The other wing of the heat flow meter is closely attached with the outboard of the water wall tube. Then heat conduction is formed. The temperature value in different positions can be measured by the thermocouples equipped in the heat conduction part, on the basis of which the heat flow density of a certain position can be calculated. The heat flow meter is equipped without damaging the water wall tube or the heating surface tube, which is easy to dismount or maintain. Thus the utility model is a novel heat flow meter.

Description

A kind of novel double-vane heat flow meter
Technical field
The utility model relates to a kind of instrument of measuring heat flux, is specifically related to a kind of heat flow meter.
Background technology
Because be subjected to the restriction of conditions such as boiler high temperature, high pressure, the heat transfer situation of change that will accurately understand regional area in the stove in boiler operatiopn has difficulties, and has influenced the economy and the security of boiler operatiopn to a certain extent.Boiler soot-blowing for example, blowing ash at present in the boiler of power plant stove generally is to adopt regularly comprehensive method of blowing ash, this method can cause on the one hand blows grey dynamics deficiency to the serious zone of coking, and influence the economy and the security of boiler operatiopn, on the other hand to the light position of coking, excessively blow ash and cause heating surface wear to increase the weight of easily, also waste energy, increase simultaneously the operation workload.Can't reach and precisely blow grey main cause in the stove is that stove internal heating surface coking degree is difficult to judge, for understanding the situation of coking in the stove, effective method is that heat flow meter is installed on heating surface, but general heat flow meter is installed on the heat pipe (as: water screen tube), need clip one section heat pipe, have unfavorable factors such as installation workload is big, improvement expenses is high, maintenance difficulties is big.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of heat pipe structure that need not to destroy, the novel double-vane heat flow meter that dismounting is simple, easy to maintenance.
In order to solve the problems of the technologies described above, the utility model by the following technical solutions:
A kind of novel double-vane heat flow meter is characterized in that: comprise a heat-conduction component that is installed in the water screen tube outside, at least two thermopairs are installed on the described heat-conduction component, heat-conduction component has respectively and adjacent two double-vanes that water screen tube fits.
The double-vane of described heat-conduction component forms the circular groove that is complementary with water screen tube.
Described heat-conduction component is installed by perforate on the water screen tube fin.
The utility model compared with prior art has following beneficial effect: perforate on the water-cooling wall fin, this heat flow meter is installed in the water-cooling wall outside of tapping, make an end of this heat flow meter directly be subjected to the heat transfer (radiation, convection current) of furnace high-temperature flue gas, the other end adopts the double-vane structure closely to contact with the water screen tube outside, form heat conduction, by the thermopair of installing on the heat-conduction component, measure the temperature value on the diverse location, can calculate heat flow density on this device according to temperature value.Utilize the variation of this measurement device hot-fluid, promptly can grasp the heat pipe heat transfer situation of change that this device zone is installed in the stove.This heat flow meter need not to destroy water screen tube or the heating surface tube structure can be installed, and dismounting is simple, and is easy to maintenance, is a kind of novel heat flow meter.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is installed in the synoptic diagram in the water-cooling wall outside for the utility model
Embodiment
Referring to Fig. 1 and Fig. 2, a kind of novel double-vane heat flow meter comprises a heat-conduction component 2 that is installed in water screen tube 1 outside, at least two thermopairs 3 are installed on the heat-conduction component 2, heat-conduction component 2 has respectively the double-vane 4 that fits with adjacent two water screen tubes 1, the double-vane 4 of heat-conduction component forms the circular groove 5 that is complementary with water screen tube 1, adopt this structure that heat flow meter is closely contacted with the water screen tube outside, form heat conduction.
When the utility model is installed, perforate on the water screen tube fin, heat flow meter is installed in the water-cooling wall outside of tapping, make its a end directly be subjected to the heat transfer (radiation, convection current) of furnace high-temperature flue gas, the other end adopts the double-vane structure closely to contact with the water screen tube outside, forms heat conduction, by the thermopair of installing on the heat-conduction component, measure the temperature value on the diverse location, can calculate heat flow density on this device according to temperature value.
