Abstract

The invention relates to a method for reforming a heating furnace with targeted heating elements. The method for reforming the heating furnace with the targeted heating elements comprises the steps that (1) the raw material texture of the targeted heating elements to be installed is determined; (2) the installation density and number of the targeted heating elements to be installed are calculatedand determined; (3) targeted heating element matrixes are made on the furnace top and the side wall of a hearth of the heating furnace; (4) the targeted heating elements are installed on the furnace top and the side wall of the hearth, the targeted heating elements are connected with a furnace lining through sintering materials, and mechanical fixation is conducted in the cold state; (5) coating treatment is conducted on the whole inner portion of the hearth with infrared thermal radiation nanometer materials; and (6) baking is conducted according to a heating curve, and after baking, the targeted heating elements and the furnace lining are sintered into a whole. By the adoption of the method for reforming the heating furnace with the targeted heating elements, radiation heat transfer in the hearth can be greatly enhanced, the service life of the furnace lining is prolonged, energy is saved, and the consumption is lowered.

Description

technical field [0001] The invention relates to an energy-saving transformation method for a heating furnace, in particular to the transformation of the heating furnace by using targeted heating elements, and belongs to the field of thermal energy engineering. Background technique [0002] On the one hand, the energy saving and consumption reduction of industrial kilns can be considered from the efficient utilization of a large amount of physical sensible heat carried by high-temperature flue gas, and on the other hand, it can also be considered comprehensively from the structural design of the kiln, the optimization of the lining material and the principle of high-temperature heat radiation. [0003] In the calcination technology, due to the large volume of the heating furnace used for calcination, the heat will converge on the upper part of the heating furnace, resulting in a large temperature difference between the upper and lower sides of the heating furnace. However, th...
