Four channel burner is now the industry more commonly used burner, here small make up and we talk about four channel burner burning some simple working principle.
Four channels burner, from the literal understanding is nothing more than four channels, respectively from the inside out for 1, central wind 2, coal powder channel or gas channel 3, swirling wind 4, outside wind.Its working principle is: pulverized coal is blown into the kiln by pulverized coal spray blower, and the flame thickness is adjusted by the contraction of the central air tube (the central air tube is generally adjustable, with a certain amount of contraction). The swirling wind scatters the pulverized coal in a certain direction to atomize and fully burn it.
The external wind is direct current, which can gather the divergent fire shape and achieve the ideal flame shape.Except the pulverized coal channel is a separate fan, the other three channels are a risk control system, according to the need to deploy valves, once adjusted fixed, easy not to adjust.At the same time, we should pay attention to the importance of secondary wind. While adjusting the primary wind, we should ensure the secondary air volume. Generally, the ratio of primary wind accounts for 10-15% of the total combustion air, and the rest is supplemented by secondary wind.Since the secondary air generally enters from the cooling cylinder, the secondary air is hot air, which can effectively improve the combustion quality and efficiency.
