Design and Implementation of Control System for Fuel Feeding

A biomass burner integrated with gas to gas heat exchanger has been designed, constructed and evaluated. The burner use three types of biomass energy fuel which is Empty Fruit Branches (EFB), wood chip and rice husk. The current biomass burner were designed with a manual biomass fuel feeder which will control the feeding volume of solidify biomass to the combustion area. The current design has a disadvantage which is the biomass feeder have to be operated manually thus the burner could not function without continuous monitoring. A control system has been designed and fabricated to modify the current biomass feeder to solve the problem. An important part of the design is to control the solid particle feeding into the combustion area without any disturbances. The system will operate when the temperature drop below 80°C and stop when it reach 90°C. The fabricated unit is tested experimentally and the result meets the objective of the project
