A device for suppressing black smoke emission

摘要

A black smoke emission suppressing device for suppressing generation of black smoke in combustion of a liquid fuel includes: a vessel having a cylindrical casing formed with a fuel inflow opening in a center of an end thereof and a fuel outflow opening in a periphery thereof, and a supply cylinder member arranged in the cylindrical casing, the supply cylinder member having one end being opened, the other end being closed, and a plurality of through holes in a periphery thereof, the opened end being connected with the fuel inflow opening of the cylindrical casing to thereby allowing the liquid fuel to flow in the supply cylinder member; and an electrostatic charger having a charging cylinder coaxially placed on an outer periphery of the supply cylinder member, the charging cylinder being formed with a plurality of spiral channels extending in radial directions, inner openings of the plurality of spiral channels being respectively connected with the plurality of through holes of the supply cylinder member to thereby allow the liquid fuel to flow in the plurality of spiral channels and then flow out from outer openings of the plurality of spiral channels.
