Investigation of the ESP Cleaning Efficiency of the Flue Gases in the Wide Range of Re numbers
Keywords:small boilers, flue gases, solid particles, electrostatic precipitator, different Re numbers
The aim of this work is to evaluate the emissions from a residential boiler (50 kW) and to investigate the properties of an electrostatic precipitator capturing the solid particles emitted during incineration of wood pellets in wide range of flue gas Re numbers (Re=4200-25000). The performed analysis demonstrated that in the case of a negative potential, the corona discharge is at smaller voltages than in the case of a positive potential and practically does not depend on the Re number. However, in the case of a positive potential, dependence on the Re number is obvious and the corona discharge is shifting to smaller voltages with decreasing of the Re number.
