Industrial Hot Air furnace manufacturers tell you that the energy-saving effect of coal-fired hot air furnaces is not only a response to the national promotion of energy conservation, emission reduction and environmental protection, but also reduces production costs and improves economy for the factory itself. Industrial Hot Air furnace manufacturers tell you that coal-fired hot air furnaces are widely used in all walks of life, and its energy-saving effect is one of its important advantages. Industrial Hot Air furnace manufacturers tell you that the energy-saving effect of a coal-fired hot blast furnace cannot be directly judged, but it is reflected in multiple indicators such as thermal efficiency, heat exchange rate, and energy consumption. The thermal efficiency depends on the drying method. Generally, the thermal efficiency of conduction drying can reach 100% in theory. If convection dry wiping is used, the thermal efficiency can only reach about 70%.

Low price Industrial Hot Air furnace from China manufacturer
The manufacturer of the Industrial Hot Air furnace tells you that the 70% heat exchange rate depends on the heat exchange area of ​​the heat exchanger, provided that the structure is the same. In addition, if there is an overall thermal insulation design, the heat loss can be minimized, and the heat exchange rate can be improved. The most fundamental way to judge the energy-saving effect of a coal-fired hot blast stove can be obtained from the heat exchange rate, that is, after reaching the corresponding hot blast temperature, the temperature of the flue gas emitted by the hot blast through the heat exchanger is high or low. If the temperature of the flue gas is high, it means that the heat exchange rate is low and the energy saving effect is poor; on the contrary, the flue gas temperature is low, the heat exchange rate is high, and the energy saving effect is good.
Industrial Hot Air furnace manufacturers tell you that energy consumption is a comprehensive indicator. Low energy consumption means that under the same drying effect, the energy consumption is low, that is to say, the thermal efficiency is high and the heat loss is small. Determine the energy-saving effect of coal-fired hot blast stove.
