Design and characterisation of an electrostatic precipitator for small heating appliances

The work presented here results from efforts to improve small heating appliances burning solid fuel. For application in small heating systems, a compact and inexpensive solution that still offers a significant reduction of particle emissions is required. In this paper, a specific design of electrostatic precipitator (ESP) is presented and its collection efficiency and electrical characteristics are evaluated. Different geometries and electrode set-ups have been considered with the aim of developing a system that can also be retrofitted to existing installations.
