Transformation heating

In newly built small-scale sulfuric acid production plants, the method of heating is usually selected based on specific requirements and cost considerations. There are advantages and disadvantages to heating with an electric furnace and heating through indirect heat exchange with diesel. The advantages of electric furnace heating are precise control, uniform temperature rise, environmental friendliness (no direct emissions), and relatively simple maintenance. The downside is that the cost of electricity may be high, especially in areas with high electricity prices. The advantage of using diesel for indirect heat exchange to raise temperature is the relatively low cost (if diesel prices are reasonable) and the mature technology. Disadvantages include pollutant emissions from combustion, as well as the need for more complex equipment maintenance and operation. The choice of method usually depends on local energy costs, environmental regulations, as well as equipment investment and operation and maintenance costs. In practical applications, indirect heat exchange using diesel is a common method for heating, but with stricter environmental regulations and lower costs of renewable energy, electric heating is gaining increasing attention. .
