Embodiment Construction
[0020] Depend on figure 2 It can be seen that the experimental furnace burner of the present invention comprises a gas inlet pipe 5, a mixing chamber 6, an air inlet pipe 7, a flange 8, a filler 9, a plug 10 and a spout, and the spout is composed of a group of 4 identical and dimensionally matched nozzles. Spout rings are spliced together. The nozzle ring is a square ring, with a large and a small frustum-shaped nozzle hole in the center of the square ring, a frustum-shaped installation groove concentric with the nozzle hole is provided on one side of the nozzle ring, and a truncated-cone-shaped clip is provided on the other side. Platform 4, the size and shape of the outlet end of the nozzle hole of the former nozzle ring is the same as the size and shape of the nozzle hole inlet end of the rear nozzle ring, the installation groove of the latter nozzle ring is set on the card platform 4 of the previous nozzle ring, and the front end The nozzle ring is connected to the bur...

The invention provides an experimental furnace burner. A nozzle of the experimental furnace burner is formed by splicing at least two nozzle rings. A frustum-shaped jet nozzle hole is formed in the center of each nozzle ring. A frustum-shaped installing groove concentric with the corresponding nozzle hole is formed in one side of each nozzle ring, and a frustum-shaped clamping table is arranged on the edge of the other side of each nozzle ring. The dimension and shape of the outlet end of the nozzle hole of the prior nozzle ring are identical to the dimension and shape of the inlet end of the nozzle hole of the next nozzle ring. The clamping table of the prior nozzle ring is sleeved with an installing groove of the next nozzle ring. The nozzle ring at the most front end is connected with a mixing cavity of the burner, and the nozzle ring at the last end is fixed to the furnace wall of an experimental furnace through wedge-shaped plugs. Due to the fact that a spliced structure is adopted, experimental burner nozzles of different structures and in different shapes are formed, fast dismounting and mounting can be achieved according to using conditions, the experiment time is shortened, the working efficiency is improved, operation is stable, the experimental furnace burner can be used repeatedly for experiments, the experiment cost is substantially reduced, and the requirements for combustion experiments in a laboratory are met.
Description
technical field [0001] The invention belongs to the field of heating appliances, in particular to an experimental furnace burner for a combustion state simulation experiment. Background technique [0002] During the use of industrial burners (burners), in order to ensure the shape and rigidity of the flame, and to ensure the full mixing of fuel and combustion-supporting air, nozzles (burner bricks) with stable flames are provided, but in different combustion methods and different fuels , Under different loads, there are large differences in the shape, structure, and material of the nozzle. At the same time, the structure of the nozzle has a great impact on the combustion characteristics such as combustion temperature. In order to analyze and study the influence of the burner nozzle device on the combustion characteristics, in Combustion laboratories in the field of thermal engineering and energy conservation are generally equipped with combustion experimental furnaces to ana...
