Important operation of energy saving in industrial kiln
Energy and environmental problems to the iron and steel enterprises and the ceramic industry and other industries to bring the rapid development of restrictive effects, energy saving and reduce emissions is the enterprise technological progress and can be the energy and environmental pollution, energy and environmental pollution, The inevitable choice for sustainable development. Industrial furnace is the key equipment for industrial heating, widely used in the national economy of high temperature industry. Industrial kiln is also a large energy consumption, its energy consumption accounts for 25% of the total energy consumption, accounting for about 60% of total industrial energy consumption.
In the energy saving process of industrial kilns, in addition to heat source transformation, sintering process transformation, combustion process transformation and furnace structure transformation, the furnace refractory and kiln refractory material performance is good or bad energy saving effect of industrial kilns have a decisive Impact, industrial refractory insulation materials are refractory fiber, refractory castable, refractory high temperature insulation coating, lightweight refractory bricks, A1302 hollow ball bricks and magnesia brick and other furnace lining fireproof insulation materials.
The calorie consumption in the industrial kiln can be decomposed into the heat absorbed by the product, the heat absorbed by the kiln, the heat from the flue gas, the heat absorbed by the kiln wall and the kiln car, and the heat of the kiln heat dissipation. The heat absorbed only for the product is the effective energy. China's energy efficiency is low, the average thermal efficiency of industrial kiln is 30%, of which 5% to 20% forging furnace, heat treatment furnace 8% to 25%, continuous heating furnace and tunnel kiln thermal efficiency is slightly higher Some, only 30% to 55%, with the international industrial furnace thermal efficiency on average more than 50% compared to a larger gap.
In response to the severe challenges of the energy situation, industrial kiln energy saving is the inevitable trend of development. Industrial kiln energy saving and kiln lining refractory material technological progress, furnace technology design and construction are closely related. Kiln lining refractory in the industrial furnace energy saving effect is through a variety of kiln lining refractory material and thermal insulation material combination, the use of fire-resistant insulation integrated lightweight refractory material as kiln body structure, the kiln body to reduce heat loss and storage Heat loss to achieve energy saving purposes.
There are many ways to combine the refractory material and the insulation material of the kiln lining. From the point of view of heat transfer, the calculation and analysis of several different thermal conductivity kiln lining refractory materials are used to analyze the composition, including heat flux density and external surface temperature change Heat transfer analysis, in order to optimize the industrial furnace kiln lining refractories, according to the use of different kiln analysis, refractory high temperature insulation coating to prevent heat conduction energy saving for the best.
