Three-dimensional conduction heat exchange combustor

Abstract

The invention belongs to the technical field of industrial furnace equipment, and relates to a three-dimensional conduction heat exchange combustor. The three-dimensional conduction heat exchange combustor comprises a heat exchanger; one axial end of the heat exchanger is tightly connected with a combustor; an air inlet and a smoke outlet are formed in the other axial end of the heat exchanger; the air inlet communicates with an intake channel in the heat exchanger; the smoke outlet communicates with a smoke channel in the heat exchanger; plates are arranged in the combustor, and are providedwith projection parts; a gas inlet and a burner are arranged at the upper end of the combustor; and the intake channel in the heat exchanger communicates with the gas inlet to realize mixing of air and gas after preheating. The combustor fully preheats combustion assisting air through a multistage heat exchange form to achieve the purposes of high efficiency and energy conservation, can be widelyapplied to heat treatment and indirect heating of nonferrous metal, is suitable for working conditions of workpieces incapable of contacting with smoke or special need of some atmosphere in the furnace, is also suitable for direct heating, and achieves the purpose of energy conservation through preheating of the combustion assisting air in a use temperature range of 500-1000 DEG C.

Description

technical field [0001] The invention belongs to the technical field of industrial furnace equipment and relates to a three-dimensional conduction heat exchange burner. Background technique [0002] The self-preheating burner is a continuous combustion heater widely used in the heating field. It has the characteristics of low calorific value, high temperature combustion, low NOX emission, safety, stability and energy saving. At present, the self-preheating structure of the burner is There are defects such as large volume, inconvenient installation, low heat conduction efficiency, easy loss of heat, and short service life. The invention provides a heat exchange burner for industrial kilns, which is the development direction of burners in the field of medium and low temperature combustion in the future. . Contents of the invention [0003] Aiming at the above problems, the present invention provides a three-dimensional conduction heat exchange burner, which fully preheats th...
