Abstract

The invention relates to an energy-saving kiln. The energy-saving kiln comprises a kiln body, a black body element and a high temperature resistance material; the kiln wall of the kiln body is provided with an installation hole of the black body element; the bottom of the black body element is provided with a boss, and the boss is in interference fit with the installation hole; and the high temperature resistance material is sintered on the kiln wall of the kiln body, and the high temperature resistance of the kiln is improved. According to the energy-saving kiln, by arranging the black body element on the wall of the kiln, the heat transfer area of a hearth is increased substantially, the emissivity of the hearth is improved, disordered heat rays are adjusted and controlled to be ordered,the in-place rate of the heat rays is increased, the irradiance to a workpiece is improved, radiative heat transfer is improved, the heat energy utilization rate is increased, and energy sources aresaved; and meanwhile, through the interference fit mode, the black body element is fixed, fixing is durable, and the structure is simple.

Description

technical field

[0001] The invention relates to the field of furnace pits, in particular to an energy-saving furnace cellar. Background technique

[0002] The heat transfer theory and a large number of engineering cases prove that the black body technology can increase the emissivity of the furnace and strengthen the radiation heat transfer of the furnace wall, which is an efficient furnace energy-saving technology.

[0003] At present, blackbody elements can only be installed on refractory brick masonry or refractory castable furnace walls. The general installation method is: the black body element is bonded on the surface of the furnace wall by an adhesive. This installation method has the problem that the black body element cannot be reliably installed on the furnace wall for a long time: the black body element has a certain weight. At the same time, the blackbody components are scoured by high-speed flame and high-temperature flue gas, and the bearing capacity of the ad...
