Technical Field
The utility model relates to a burner for a gas heating furnace, in particular to a universal burner with a switching and adjusting device for the gas heating furnace, and belongs to the technical field of gas combustion.
Background
The gas furnace is a common heating device in industrial production, and is used for transferring the heat energy of gas to a heated workpiece through combustion conversion, so that the temperature of the workpiece is increased to meet the technological requirement. This energy conversion process is accomplished by burner combustion. The burner is a heat energy conversion device which sends fuel gas and oxygen-containing air into a hearth to burn stably according to the concentration, flow, turbulence and mixing mode required by combustion. The existing burner cannot adapt to different fuel gas combustion, such as a special burner for both coal gas and natural gas. However, because the supply amount and the price of market gas resources are continuously changed, the price is sometimes too high when natural gas is singly used, the production cost is increased, and the limited supply is also caused in special cases, so that the production is influenced; the single use of coal gas sometimes results in contradiction between supply and demand. Therefore, in enterprises with large fuel gas consumption, it is desired to switch between natural gas and coal gas, but the above-mentioned objects cannot be achieved because the burner cannot be used in common, and it is desired to have a burner which can be adapted to a plurality of different fuel gases to solve the urgent need.
