Abstract
An igniter element for igniting solid fuel particles in a retort furnace is disclosed. The igniter element is a substantially planar shaped element that is in direct contact with the fuel to be ignited. A configuration of various sections is formed into the planar igniter element in order to facilitate the conversion of electrical energy into thermal energy. The igniter element uses a control system to reliably facilitate the ignition of all solid fuels including difficult to start fuels, such as anthracite coal. The service life of the heat igniter is extended by its planar shape in contact with the surface of the retort and its ability to dissipate the thermal energy produced within the retort region.
Claims21
A device for igniting solid fuel in a solid particle fuel burning furnace comprising an electrically conductive igniter element connected to a retort of the furnace, wherein the igniter element has a configuration consisting of a plurality of sections.
A method for igniting solid fuel particles in a retort furnace comprising the steps of:
- a) providing solid fuel particles from a hopper to a horizontal fuel transporter;
- b) urging the solid fuel particles down the horizontal fuel transporter into direct contact with an igniter element;
- c) providing sufficient electricity to the igniter element to heat the solid fuel particles to at least their ignition temperature;
- and
- d) introducing combustion air to the heated solid fuel particles to begin combustion of the solid fuel particles.
