Abstract
As a burner for boiler equipped on the L.N.G. carrier, the gas/oil combined burners having some special performances are needed in respect of the operating conditions.
The firing test was carried out by use of Chugai Ro-Hamworthy HXG burner which has been developed for a long period of time in order to be furnished with the above-mentioned special performances.
Burner performances investigated in the test are as follows:
1) Minimum excess air ratio.
2) Variations of flame length against gas-oil firing ratio.
3) Stability of oil flame under such burner operating conditions as ignition and shutting-off of fuel gas.
4) Relation between the blowing volume of N2gas and stability of flame.
5) Temperature of gas nozzle tip under each operating condition.
6) Variations of register draught loss against gas-oil firing ratio.
The results of the test are shown concretely on the tables and figures for the convenience of designing the combustion equipment for L.N.G. carrier.
