Apparatus for Oil Flow Control

An apparatus for controlling a fuel oil, comprising

• An oil pump 10 for drawing the fuel oil from a source and raising a pressure of the fuel oil;
• A pressure regulator 15 for regulating the pressure of the fuel oil downstream of the pressure regulator to a desired value;
• A trim heater 20 for controlling a temperature of the fuel oil;
• A temperature sensor 30 for measuring the temperature the fuel oil;
• A flow control valve (FCV) 40 for controlling a flow rate of fuel oil;
• A flow meter 50 for measuring the flow rate of the fuel oil;
• A combustion controller 70;
• A heater controller 90;
• and
• A burner capable of burning said fuel oil in a boiler, wherein the combustion controller 70 receives a call for heat signal from the boiler, and determines a target flow rate of the fuel oil for the heater controller 90 and a target setting for the FCV 40;
• the heater controller 90 receives feedback signals from the temperature sensor 30 and the flow meter 50, and controls the trim heater 20 to drive the flow rate of the fuel oil toward the target flow rate of the fuel oil.
