A fully automatic oil (gas) burner with good performance is installed on a boiler. Whether it still has the same good combustion performance largely depends on whether the gas dynamic characteristics of the two match. Only a good match can give play to the performance of the burner, ensure the stable combustion of the furnace, achieve the expected heat output and obtain the good thermal efficiency of the boiler.
A single type full-automatic combustor is like a flame ejector, which injects the flame into the furnace (combustion chamber) to realize complete combustion and output heat in the furnace; the combustion completeness of products measured by the combustor manufacturer is carried out in a specific standard combustion chamber. Therefore, the conditions of standard experiment are generally used as the selection conditions of combustor and boiler.
The power of the combustion engine refers to how much mass (kg) or volume (m3 / h, under standard state) fuel it can burn per hour when fully burned, and also gives the corresponding thermal energy output (kW / h or kcal / h). While the boiler is calibrated for steam output and fuel consumption, and the two must be matched when selected.
In an oil (gas) boiler, the hot gas flow starts from the combustion engine and is discharged to the atmosphere through the furnace, heat exchanger, flue gas collector and exhaust chimney to form a fluid thermal process. The hot gas flow generated after combustion flows in the furnace channel with the upstream pressure head, just like the water in the river, and the level difference (drop, head) flows downstream.
