Study of Heating Efficiency Improvement for Multi-hole Gas Burner by Forced Air Supply

摘要

This study shows the experimental result that the influence of the forced air supply for multi-hole gas burner. The parameters are chosen as the flame hole angle, the flow rate and the distance between the air nozzle head and heating object. LPG(Liquefied petroleum gas) is used for the test fuel gas. The compositions of LPG are propane 97.5 vol%, butane 0.2 vol% and methane + ethylene 2.3 vol%. The flame temperature measurement is carried out by K type thermocouple. The analysis of combustion gas is carried out by a gas analysis device. It is clarified that the foreed air supply is effective method for heating efficiency improvement of the multi-hole gas burner.
