Detailed Description
The present utility model will be described in detail below with reference to the drawings attached to the specification.
As shown in the figure, the variable gas burner comprises a gas inlet channel and a gas outlet channel, wherein the gas outlet channel is at least formed by three gas outlet pipes 5 with different diameters, the gas outlet pipes 5 are sleeved together, the inner gas outlet pipe and the outer gas outlet pipe 5 are connected through a supporting plate, the gas inlet channel is at least formed by two gas inlet pipes 1, one gas inlet pipe is a gas inlet pipe, the other gas inlet pipe is an air inlet pipe 11, the gas inlet pipes 1 are all provided with gas inlet valves 2, the tail ends of the gas outlet pipes 5 are provided with gas guide pipes 3, the quantity of the gas guide pipes 3 at the tail ends of the same gas outlet pipe 5 is the same as that of the gas inlet pipes 1, the gas inlet pipes 1 are connected with each gas outlet pipe 5 through the gas guide pipes 3, and the gas guide valves 4 are all arranged on each gas guide pipe 3.
According to the experiment, under the condition that the number of the air inlet pipe 1 and the air outlet pipe 5 is four, the combustion requirements of the existing fuel gas with various heat values can be met.
The working principle is as follows: taking the case that the number of the air inlet pipes 1 and the air outlet pipes 5 is four as an example, the four air inlet pipes 1 are respectively an air main pipe 11, a natural gas main pipe 12, a converter gas main pipe 13 and other gas main pipes 14, and the four air outlet pipes 5 are sequentially provided with a first air outlet pipe 51, a second air outlet pipe 52, a third air outlet pipe 53 and a fourth air outlet pipe 54 from inside to outside.
When natural gas (heat value 8500 kcal) is combusted, the air inlet valve 2 on the natural gas main pipe 12 is opened, the air guide valve 4 between the natural gas main pipe 12 and the second air outlet pipe 52 is opened, so that natural gas enters the second air outlet pipe 52 through the air guide pipe 3, the air inlet valve 2 on the air main pipe 11 is opened, and the air guide valves 4 between the air pipe 11 and the first air outlet pipe 51, the third air outlet pipe 53 and the fourth air outlet pipe 54 are opened, so that air enters the first air outlet pipe 51, the third air outlet pipe 53 and the fourth air outlet pipe 54 through the air guide pipe 3 respectively, and the effect of the combustion is that the second air outlet pipe 52 provides fuel gas, and the first air outlet pipe 51, the third air outlet pipe 53 and the fourth air outlet pipe 54 provide air, so that the fuel gas and the air are uniformly mixed, and a flame organization form with central wind is formed.
When the converter gas is combusted (the calorific value is 1200 kcal), the air inlet valve 2 on the converter gas main pipe 13 is opened, then the air guide valve 4 between the converter gas main pipe 13 and the first air outlet pipe 51, the second air outlet pipe 52 and the third air outlet pipe 53 is opened, so that the converter gas respectively enters the first air outlet pipe 51, the second air outlet pipe 52 and the third air outlet pipe 53, then the air inlet valve 2 on the air main pipe 11 is opened, and the air guide valve 4 between the air pipe 11 and the fourth air outlet pipe 54 is opened, so that the effect of the combustion is that the first air outlet pipe 51, the second air outlet pipe 52 and the third air outlet pipe 53 provide fuel gas, and the fourth air outlet pipe 54 provides air, thereby forming a low calorific value flame structure form.
By analogy, the design can increase or decrease the opening quantity of the air outlet pipe 5 according to different types of fuel gas, and can be arbitrarily combined between the air inlet pipe 1 and the air outlet pipe 5 through opening or closing the air guide valve 4, so that the combustion requirements of fuels with different heat values are met.
