Solid fuel burner with electrodynamic homogenization

摘要

A solid fuel burner may include a system for electrodynamic homogenization. One or more electrodes may apply an electric field to burning solid fuel or a region proximate the burning solid fuel. The electric field causes mixing and homogenization of volatilized fractions of the solid fuel, combustion gases, and air. The improved mixing and homogenization may reduce emission of carbon monoxide (CO), reduce emission of oxides of nitrogen (NOx), reduce oxygen in flue gas, increase temperature of flue gas, and/or allow for a larger grate surface.

主权项

1. A solid fuel burner with electrodynamic homogenization, comprising:
a grate configured to support a burning solid fuel; an underfire air source configured to deliver underfire air to the burning solid fuel from below the grate; an electrode configured to apply an electric field to the burning solid fuel or a region proximate the burning solid fuel; a fuel cache operatively coupled to a fuel stoker; and electrical insulation between the fuel cache and a support structure; wherein the fuel cache and the electrical insulation are configured to reduce or eliminate current leakage from the electric field through the fuel stoker and fuel positioned near a fuel stoker intake; and wherein the electric field is selected to cause mixing and homogenization of volatilized fractions of the solid fuel, combustion gases, and air.
