Heat exchanger
Thread Content
1. Equipment upgrade. Replace the steam heat exchanger; use 25 kilograms of saturated steam to heat the air, with the aim of raising its temperature from 10 degrees to 175/195 degrees. The temperature of the condensed water is 160 degrees, and the fan has a capacity of around 30,000 Nm3/h. The steam consumption is required to be no more than 100 KG per hour. I ask all the teachers to help design the heat exchanger. Thank you. There are no strict requirements for the condensate water temperature.
There might be an issue with what you’re saying. On the hot side, 25 kilograms of steam at saturation can be turned into hot water at temperatures of 30–50°C. On the cold side, air at a volume of 30,000 standard cubic meters results in temperatures ranging from 10 to 180°C; the heat generated is approximately 1.8 megawatts. To produce this amount of heat, around 3 tons of steam are needed. My QQ number is 2368619091
Have you got the steam volume wrong? Based on the parameters you provided, more than 3 tons of steam are needed to meet the requirements.
