Abstract

The invention discloses an energy-saving industrial furnace. The energy-saving industrial furnace comprises a furnace base body, and the furnace base body is made of heatproof fibers, firebricks or a micro-nano material; the outer wall of the furnace base body is coated with a combined heat insulation coating layer, and the inner wall of the furnace base body is coated with an infrared radiation energy-saving coating layer; and the combined heat insulation coating layer comprises an inner heat insulation coating layer, a medium heat insulation coating layer and an outer heat insulation coating layer which are sequentially coated from inside to outside. A reinforced radiation heat transfer combined thermodynamic heat insulation energy-saving technology, which combines the infrared high-radiation technology of the high temperature-resistant infrared-energy saving coating layer with the high-efficiency heat insulation technology of the combined heat insulation coating layer, is applied, so the industrial furnace disclosed in the invention has the characteristics of effective improvement of the heat utilization efficiency, good energy saving effect, long service time, prolonged service life, and generation of the environmental protection effect.

Description

technical field [0001] The invention relates to an energy-saving industrial furnace. Background technique [0002] Industrial furnaces are high-energy-consuming equipment among many energy-consuming equipment, and their energy consumption accounts for about 10% to 70% of the energy consumption of enterprises, and some are even more. Taking the electronics industry furnace as an example, its energy consumption accounts for about 30% of the energy consumption of the electronics industry; the energy consumption of the furnaces of ceramic and glass production enterprises accounts for about 50% of the energy consumption of the enterprise, and some are even higher. [0003] Due to the influence of factors such as product production process, production organization, furnace structure, and furnace base material, the heat utilization efficiency of industrial furnaces is relatively low. For example, the thermal efficiency of the flat glass furnace is about 36%, the thermal efficiency...
