MODULAR INDUSTRIAL MICROWAVE FURNACE

摘要

There is provided an industrial microwave furnace comprising a metal casing subdivided into three adjacent compartments by partitions having each an opening in an upper part thereof. The two outer compartments each include a number of microwave generators and are each pressurized by a flow of cool air from an associated air fan. The microwave generators are disposed opposite the openings in the partitions such that warm air resulting from cooling of the microwave generators by the flow of cool air is directed through the openings into the middle compartment which forms a microwave applicator section. The industrial microwave furnace further comprises a plurality of waveguides arranged on the walls of the casing and a plurality of radiators for coupling the microwave energy from the microwave generators in the waveguides and for coupling the microwave energy from the waveguides into the middle applicator compartment. The radiators are evenly distributed along the waveguides so as to create a constant electric field over the cross-section of the middle applicator compartment, thereby to result in a constant heating over the crosssection of the middle applicator compartment and in a maximum microwave energy coupled into the middle applicator compartment.
