Energy-saving measures for industrial furnaces

Date of release:2018-12-27 Author: Click:

     

Energy saving must have scientific measure and comparative test method. At present, the accepted testing method is heat balance test. Through the thermal measurement of industrial furnace, comprehensive understanding of the thermal process of anhui industrial furnace, heating furnace of analysis and diagnosis of "illness", find out the "cause", energy-saving technological transformation, to further improve thermal efficiency of heating furnace, consumption, and to obtain the parameters of heating furnace operation economic and technical performance indicators and analysis of heating furnace operation, timely adjust the furnace condition, to the running state of the better, so as to find out the effective ways to save energy and direction.

When designing or improving the furnace, the new type energy-saving anhui industrial furnace should be selected according to the production process requirements. Choose proper furnace type structure, improve mechanization degree and energy efficiency. Currently, the following energy-saving measures are commonly adopted:

1, the use of circular furnace instead of box-shaped furnace, furnace can enhance the effect of uniform heat transfer on the workpiece, reduce the heat loss of the furnace wall, so that the furnace form a heat exchange system, heat exchange between the heating element, furnace lining and the workpiece 3. By using reasonable furnace space and increasing the inner wall area of the furnace without increasing the space volume of the furnace, the heat exchange of the furnace is improved by increasing the heat exchange area so as to improve the thermal efficiency.

2. A fan is installed in the furnace to enhance the convection and heat transfer in the furnace. In particular, small heating furnace, high-speed air flow can destroy the stagnation on the surface of the workpiece hinder heat transfer and interface reaction furnace gas boundary bottom layer, play a role in shortening the heating time and speed up the workpiece temperature.

3, the furnace body seal, including the furnace in the lead out of the components, furnace shell, door, etc. The furnace body seal is not strict, will cause everywhere to run the fire, the leakage fire, causes the energy to waste massively, the equipment to burn bad, the environment to be bad and so on, therefore the furnace body seal directly affects the work piece quality and the energy consumption, simultaneously the seal is also in the furnace atmosphere control key. The appearance of refractory fiber products created conditions for solving furnace seal and realized soft seal.

4, the use of refractory castable integral casting furnace with high strength, integrity, good air tightness, long life and other advantages.

5. New furnace materials are adopted to optimize the lining structure. Under the premise of guaranteeing the structural strength and heat resistance of furnace lining, the heat preservation ability and heat saving should be improved as far as possible. It will not only increase the heat and cost of furnace lining, but also reduce the effective utilization rate of furnace bottom area. Refractory fiber and rock wool are selected as insulation layer and lightweight brick is used as inner lining of furnace body to reduce heat storage loss of furnace body, enhance heat insulation of furnace and reduce heat loss of furnace wall.

6, in the furnace wall coated with high temperature and high radiation coating, strengthen the radiation heat transfer in the furnace, conducive to the full use of heat energy, its energy saving effect of 3% ~ 5%, is the recent more advanced energy saving method.

In addition to tapping potential in equipment and technology, energy saving in industrial furnaces should also include manpower in energy management. We will strengthen energy management in terms of organization, production and operation. Efficient organization of production, strengthen equipment maintenance, play to the capacity of equipment, so that the furnace efficient operation. Improve the operation level, strengthen the planning and scheduling, and the energy use process caused by the run, run, drop, leakage and other energy waste phenomenon to check and deal with, effectively put an end to all kinds of tangible losses.
