Description
Technical Field
The utility model relates to a heating furnace field specifically is a high-efficient energy-conserving through-type heating furnace.
Background
Heating furnaces, various industrial furnaces and boilers are high-energy-consumption kilns, and the resource consumption is large. The heating furnace has high temperature when heating the steel ingot, and a large amount of high-temperature heat is taken away by the flue gas, thereby causing waste and low heat utilization rate. The measures for saving energy and reducing consumption are as follows:
1. the RLHY-2 black body radiation energy-saving coating is coated on the inner wall of the heating furnace, so that the radiation rate of refractory materials of the wall of the heating furnace is increased, the radiation heat exchange in the furnace is accelerated, and the energy-saving rate of the product is 10-20%.
2. The high-emissivity barrel-shaped device is additionally arranged on the inner wall of the heating furnace, the high-emissivity barrel-shaped device also has the effects of improving the emissivity of refractory materials of the furnace wall, accelerating the radiation heat exchange in the furnace, and realizing the energy saving rate of 3-6% of products.
3. The purpose of waste heat recovery can be achieved by using the honeycomb ceramic heat accumulator, but the one-time investment is large, the switching mechanism is more, and the maintenance cost is high; in addition, a great amount of gas which is blown out by the burner but is not combusted is also taken away in the switching process, so that the energy is seriously lost. The heat exchanger can make up the defects of the honeycomb ceramics, and has the advantages of low investment, no switching mechanism and no maintenance.
If a metal heat exchanger is used, the oxidation resistance is poor due to the limitation of materials, the metal heat exchanger cannot be used at high temperature for a long time, and the waste heat recovery rate is low. If the temperature of the flue reaches over 800 ℃, the metal heat exchanger is very easy to be damaged by high temperature, and the purpose of waste heat recovery cannot be achieved.
If the kiln temperature is higher than 800 ℃ and the flue temperature is lower than 800 ℃ under the ordinary condition, the metal heat exchanger is suitable for the condition, but if the conditions of power failure, large gas quantity, insufficient combustion-supporting air quantity and the like occur, the flue temperature is quickly higher than 800 ℃, so that the metal heat exchanger is quickly burnt out;
in the past, a burner is arranged on the top, a heating point is too local, local overheating is easily caused, heating is not uniform, and energy consumption is high.
