    Abstract

    For many years people realized that the needs of energy is an expensive basic needed for human life, especially energy from fossil, such as crude oil, gas, and coal. At oil refinery factory or electrical generator unit, heat is the mostly dominant of utilization and oil refinery factory product price structure. A boiler is steam producer. Heat produced by the fuel combustion reaction will transfer through convection and radiation process to boiler feed water (BFW) until produce good steam with saturated quality or reach superheated steam. A dominant operation problem is uncomplete combustion process caused by uncomplete ratio of air–fuel. This problem caused by the addition of deposite or sealling inside and outside of tube fire heater. Sealing in the tube usually influences BFW quality that carried many impurities then sealed at the wall inside of the tube. Deposite sealed at ouside of tube formed by uncomplete combustion. Fired heater performance will be reduced because of carbon deposite. The point of this research is to study the effect of steam flow variation on burner and tubing to the increasing of heat and temperature also quality of steam as caused by steam reaction with haevy oil and air on burner and steam reaction with carbon on tubing happen for combustion on fired hater. This research use package boiler B&W series 1986 model which can be seen at oil refinery factory or steam power electrical generator unit at Indonesia. Two thermodynamics process that will be observed at this research are combustion process and heat transfer process, approximately convection is the dominant method at this heat transfer process. This package boiler has 50 kgs/hours steam production capacity, superheated steam qualified, maximum pressure 7 kgs/cms2 and maximum temperature 700 oC. Quantitatively, the heat efficiency which is corresponded to the temperature increasing caused by steam injection that can be achieved as 41.25% and the specific enthalphy is 12.07%.
