How does the coil of a hot oil furnace (hot coal furnace) prevent uneven burning? A regular furnace, with three inlets and three outlets, without flow meters or thermometers? Is there any relatively simple way to prevent uneven burning?
The length of both the inner coil and the middle coil is between one-fourth and one-half of the length of the outer coil. A short flue is formed between the inner coil and the middle coil, and another short flue is formed between the middle coil and the outer coil. A long flue is formed between the outer coil and the cylinder of the furnace housing. A chimney is located on the outside of the furnace housing, and a larger ash collection area is provided at the rear end of the furnace housing； The combustion apparatus includes a burner, a fuel delivery pipeline assembly, an ignition device, and a radiation chamber; the radiation chamber forms a flue gas passage together with two short flues, an ash collection area, a long flue, and a chimney.
The key is to ensure that the hot oil circulation pump operates properly, so that the flow rate of the hot oil through the coil is maintained; by preventing the flow rate from becoming too low, uneven burning can be avoided.
Xiao Qiang, regularly use an infrared thermometer to measure the temperature of the furnace tubes, and adjust the flow rate by adjusting the valve opening.
It is sufficient to control the flow rate of the heat transfer oil, ensuring that its flow rate is not less than 4 meters per second.
