Problems solved by technology

The disadvantage of this method is that although a higher temperature can be generated, the test environment is different from the flame. Substantial difference, while the maximum range of temperature is also limited
The second is the combustion chamber used in the laboratory and the measurement results of the auxiliary thermocouple as the test environment of the optical combustion measurement technology. Its disadvantage is that the temperature distribution of the flame is not uniform, and the thermocouple itself is also limited by the temperature measurement.
[0004] Through the research of the existing technology, the inventor found that the current testing and calibration methods have the problem that the temperature range is limited and the combustion environment cannot be truly simulated, which will bring errors to the measurement technology

Embodiment 1

[0035] figure 1 It is a schematic diagram of the structure of the flat flame furnace device provided in the first embodiment of the present invention, and the device includes:

[0036] The furnace body 101A and 101B, the honeycomb pressing plate 102, the furnace body fixing bolt 103, the steel pipe seat 104, the base 105, the honeycomb structure body 106, the metal capillary tube 107, the air and gas fuel inlet pipes 108A and 108B.

[0037] The furnace bodies 101A and 101B are connected and positioned by the furnace body fixing bolts 103 and positioning pins, which is convenient for disassembly, assembly and maintenance of the flat flame furnace. The joint surface of the furnace body adopts sealing methods such as sealing ring or plane seal to ensure that the inside of the furnace body is isolated from the outside air.

[0038] The honeycomb pressing plate 102 is used to fix the honeycomb structure 106 to ensure the position and stability of the honeycomb structure.

[0039] The steel...

Embodiment 2

[0050] See figure 2 As shown, another technical solution of the flat flame furnace structure design provided in this embodiment:

[0051] 201A and 201B are furnace bodies;

[0052] 202A, gas fuel inlet pipe;

[0053] 202B, air inlet pipe;

[0054] 203, is a honeycomb pressing plate;

[0055] 204, is an inert gas such as nitrogen accompanied by a flow outlet;

[0056] 205, is the flame burning area of ​​the honeycomb structure.

[0057] Compared with the flat flame furnace structure design solution provided in the first embodiment, the embodiment of the present invention adds the nitrogen and other inert gas accompanying flow outlets 204 to the honeycomb structure, and adds the corresponding inert gas to the furnace structure. Air chamber. The inert gas such as nitrogen is accompanied by the flow outlet 204, which adopts a honeycomb structure similar to the honeycomb structure 205 and is composed of uniformly distributed regular hexagonal cells to ensure that the inert gas such as nitr...

Abstract

The invention discloses a structural design scheme of a flat flame furnace. The structure comprisess: a furnace body, a base, a honeycomb structure body, a pressing plate and a steel-tube seat, wherein the furnace body is flat flame furnace main structure, and the furnace body adopts split design so as to facilitate disassembly, assembly and maintenance of the flat flame furnace; the base forms a combustion gas chamber of the flat flame furnace and is used for introduction of gas fuel; the honeycomb structure body is used for uniform mixing of gas fuel and air; the pressing plate is used for fixing the honeycomb structure int the furnace body; and the steel-tube seat is used for isolating fuel gas and air so as to avoid premixing of fuel gas and air in the furnace body. The structural design scheme of the flat flame furnace is capable of ensuring that fuel gas and air are uniformly mixed at the furnace outlet, combustion flame with even temperature distribution can be generated, and the overall structure of the furnace body is easy to disassemble, assemble and maintain.
