Abstract

The utility model relates to a novel external-cooling type heat flow meter. The heat flow meter comprises a heat conduction component mounted on the outer side of a water wall tube, wherein at least two thermocouples are mounted on the heat conduction component; a cooling device is arranged at a low-temperature end of the heat conduction component; and circular arc-shaped grooves matched with the water wall tube are respectively formed on two sides of the heat conduction component. Compared with the prior art, the utility model has the following benefits: an opening is formed on a water wall fin; the heat flow meter is mounted on the outer side of the water wall tube at the opening; one end of the heat flow meter directly receives the heat transmission (such as radiation and convection) of high-temperature flue gas inside a furnace, and the other end thereof is cooled by a cooling medium of the cooling device outside the furnace, so that heat conduction can be achieved; temperature values in different positions can be measured through the thermocouples mounted on the heat conduction component; and the heat-flow density on the device can be calculated according to the temperature values. The heat flow meter can be mounted without damaging the water wall tube or a heated face tube and can be disassembled and assembled simply.

Description

The novel heat flow meter of a kind of external-cooling type
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 the comprehensive grey method of blowing.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, to the light position of coking, excessively blow ash and cause heating surface wear to increase the weight of easily on the other hand, 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 the effective method of the situation of understanding coking in the stove 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 heat flow meter of external-cooling type 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:
The novel heat flow meter of a kind of external-cooling type comprises a heat-conduction component that is installed in the water screen tube outside, and at least two thermopairs are installed on the described heat-conduction component, and the low-temperature end of heat-conduction component is provided with cooling device.
Described heat-conduction component forms the circular groove that is complementary with water screen tube.
Described circular groove is located at the both sides of heat-conduction component respectively.
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 screen tube outside of tapping, make its a end directly be subjected to the heat transfer (radiation, convection current) of furnace high-temperature flue gas, other end heat eliminating medium by cooling device outside stove cools off, 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 this heat flow meter to measure the variation of 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
