Description
Technical Field
The utility model relates to a combustion apparatus especially relates to a formula burning economizer system is mixed in advance outside kiln.
Background
The combustion system is a key part of the kiln and is a core structure for heating, most of the used fuels of the kiln for firing ceramic products are gases, such as natural gas, liquefied petroleum gas, coal gas and the like, and air and the fuels are usually mixed in a burner and then are combusted for heating.
Different fuel components have different heat values, and the difference of the required air proportion is large, for example, the volume ratio of the clean natural gas to the air after being mixed and completely combusted is about 1: (10-12), the volume ratio of the liquefied petroleum gas to the air in complete combustion is about 1: (24-30). In the actual process, the air-air ratio is difficult to reach the theoretical combustion state, and incomplete combustion can be caused by excessive gas or excessive air, so that a large amount of waste gas is generated, fuel is wasted, and the power consumption of an exhaust fan is increased. These problems occur if the mixing is not uniform, even if the air and fuel are properly proportioned, so that a reasonable air-fuel ratio and a uniform and rapid mixing are important.
At present, the proportion of air and gas is generally controlled by the sizes of an air outlet and an air jet hole of a combustion-supporting air swirl plate of a burner core, and combustion-supporting air enters a combustion chamber from the swirl plate and fuel from holes of a jet head to be mixed and combusted. In addition, combustion-supporting air of most of burners of the kiln is controlled by a manual valve, and the temperature change in the kiln is controlled by automatically opening and closing a fuel gas through an electric valve. The structure is a rough mode no matter the mixing or the air-air ratio is adopted, the valve opening and closing size and the flow and the pressure are in a nonlinear increasing and decreasing relation, and the size of the valve opening and closing size and the flow and the pressure are changed continuously, in the process of automatically adjusting the temperature, sometimes the valve opening and closing size rolls due to too large dense smoke, sometimes flameout is caused due to excessive air quantity, sometimes the flame is unstable due to uneven air-air mixing, the product quality fluctuation is large, and the unit energy consumption is high.
In addition, there is a overgrate air mixed structure, set up two wind channels, a gas pipe in the nozzle inside, burn after mixing with a small amount of wind and gas for the first time, the secondary is sprayed combustion-supporting wind directly into the combustion products and is further fully burnt, still can't reach the best combustion effect to the nozzle block is first big (account for kiln wall space, outside heat dissipation is serious), the structure is complicated, the cost is high, is difficult to obtain effective popularization.
