The invention provides an
afterburner with an
airflow channel designed in a rectifying support plate, the oil and
gas mixing degree can be effectively improved, the
mixed gas staying time is prolonged, and the
combustion efficiency is improved.
Airflow from an inner duct and an outer duct is mixed among rectifying support plate
flame stabilizers through a sliding baffle type rear duct ejector,
airflow enters the support plate from small air inlet holes formed in the surfaces of the two sides of the rectifying support plate
flame stabilizers and passes through the
airflow channel formed by partition plates, the speed is reduced in the process,
fuel oil in
fuel oil channels is heated, then the
fuel oil is sprayed out towards the center on the back through small air spraying holes formed in the surfaces of the
tail flame stabilizers, the fuel oil enters fuel oil channels in the rectifying support plate flame stabilizers through
oil supply pipelines, after being heated, the fuel oil is sprayed out through small oil spraying holes connected with the surfaces of the flame stabilizers, the fuel oil is disturbed through multiple strands of airflow, the fuel oil is further heated and mixed with the airflow, and
combustion is conducted in a back low-speed
backflow area. The fuel oil is good in heating, atomizing and
evaporation effect and is disturbed by the airflow, the oil and
gas mixing time is long in the low-speed area, accordingly the oil and
gas mixing effect is good, and therefore the
combustion efficiency can be improved. Meanwhile, ignition and stable combustion can be achieved under the condition of the small oil and gas ratio.
