The furnace main performance indicators

The furnace main performance indicators

The main performance of the furnace is mainly determined by the technical and economic performance of the fire-resistant insulation materials, direct impact on the investment cost of the furnace, work performance, thermal efficiency, running energy consumption costs. Select the general principles of the fire-resistant insulation materials:

    1, furnace performance and thermal characteristics. Such as working intermittently furnace should be used in materials with low thermal capacity

    2, the safe use of the material temperature, the thermal system, the high-temperature strength, chemical stability

    3, the use of life

    4, the investment costs and operation and maintenance costs

Generally speaking, heavy refractory focus on a technical performance indicators, such as high temperature stability, chemical stability; pay more attention to the technical and economic indicators of the investment and running resistance, lightweight insulation material.

Selection of lightweight insulation materials, insulation materials, thermal conductivity (lambda) to determine the cost per unit volume of insulation materials (p) of the λΡ value of the product as small as possible. Small values ​​of thermal conductivity, good insulation effect of the insulation material, the runtime energy costs low. Per unit volume of insulation materials low cost low investment costs, with good economic efficiency of investment. Can coordinate graphical method mapping selection, the horizontal axis is the operating temperature, the vertical axis is (λΡ) good product, interception of the curve of the material with the safe use of the temperature of the material, select the material with good technical and economic performance.
