Abstract
The utility model relates to an integrated type thermal-efficiency measuring device, in particular to a device used for simultaneously measuring the fuel-gas temperature and the oxygen content. A thermocouple and a fuel-gas sampling gun are fixedly arranged in a sleeve, the test end of the thermocouple and the sampling end of the fuel-gas sampling gun are arranged outside the sleeve, and the other end of the thermocouple is connected with an FLUKE; and the other end of the fuel-gas sampling gun is connected with a fuel-gas analyzer. In the utility model, the fuel-gas sampling gun and the thermocouple are assembled in the sleeve which has novel design according to the aim of the integration of the fuel-gas measurement and the temperature measurement. The unitarity of the device is solved, thereby the simple, high-efficient and clean fuel-gas and temperature measuring processes can be ensured, the working condition of the thermocouple can be improved, the measuring precision is high, and the workload and the maintenance amount of the operation personnel can be lightened.
Description
Technical field
The utility model relates to integral type thermal efficiency measurement mechanism, is specially a kind of device of measuring the gentle oxygen amount of cigarette simultaneously.
Background technology
When the fuel-burning power plant coal-powder boiler being carried out the measurement of boiler heating rate, need measure the oxygen amount and the flue-gas temperature of boiler air preheater outlet with gridding method.In measurement, to flue gas sampling rifle and flue gas analyzer be coupled together, also need on the flue gas sampling rifle, bind the thermocouple measurement flue-gas temperature in order to measure flue-gas temperature simultaneously with emulsion tube.Need carry out preliminary work before a large amount of tests for carrying out this test, and might there be error in thermopair, thereby influences accuracy of experimental results.From the working environment of thermopair, owing to be in the flue gas of high temperature, the phenomenon that the epidermis of thermopair exists high temperature corrosion, oxidation to come off causes the exposed measuring accuracy that influences of thermopair.And the serviceable life of thermopair is short, needs often to change, and work brings very big inconvenience to site test.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of easy to use and can conveniently read the flue gas sampling and the incorporate device of temperature survey of test findings.
The utility model adopts following technical scheme:
The utility model is provided with thermopair and flue gas sampling rifle at the sleeve internal fixation, and the sampling end of the test lead flue gas sampling rifle of thermopair is arranged on outside the sleeve, and the other end of thermopair is connected with FLUKE; The other end of flue gas sampling rifle is connected with flue gas analyzer.
The utility model good effect is as follows: the utility model is pressed flue gas and is measured and the incorporate purpose of temperature survey, and flue gas sampling rifle and thermopair are assembled in the futuramic sleeve pipe.Solved the unitarity of device, made that flue gas and temperature survey process are simple, efficient, cleaning, the thermopair working environment improves, and the measuring accuracy height has alleviated operating personnel's workload and maintenance.The utility model has the precision height with flue gas sampling rifle and thermocouple junction altogether, and superiority such as long service life are the upgraded products of present flue gas sampling device, can be widely used in the thermal efficiency test of coal-powder boiler, industrial furnace.
Description of drawings
Accompanying drawing is the utility model structural representation
In the accompanying drawings: 1 thermopair, 2 flue gas sampling rifles, 3 sleeves, 4.FLUKE, 5 flue gas analyzers.
Embodiment
As shown in drawings, the utility model is installed in flue gas sampling rifle 2 and thermopair 1 in the sleeve 3, and sleeve 3 length are 2.5m, are made by stainless-steel tube.
Flue gas sampling rifle 2 is arranged in the sleeve 3, and the sampling head exposes sleeve 5cm, and the other end exceeds sleeve 10cm and is connected to flue gas analyzer 5 by emulsion tube.
Thermopair 1 is between smoke sampling rifle 2 and sleeve 3, and an end exposes sleeve 3 slightly, and is then that sleeve 3 is dead with 2 welderings of flue gas sampling rifle, prevents that flue gas from entering between sleeve 3 and the flue gas sampling pipe, and protection thermopair 1 increases the service life.The other end is drawn and is connected to FLUKE measurement flue-gas temperature.
As shown in the figure, when measuring the utility model device is inserted in the gaging hole, with emulsion tube flue gas sampling rifle 2 is connected with flue gas analyzer 5, FLUIKE is connected on the thermopair, plugs the utility model device up and down according to gridding method and measures flue gas oxygen amount and temperature simultaneously.
The utility model has the precision height with flue gas sampling rifle and thermocouple junction altogether, and superiority such as long service life are the upgraded products of present flue gas sampling device, can be widely used in the thermal efficiency test of coal-powder boiler, industrial furnace.
