Calculation of heat exchange area for waste heat from flue gas in heat transfer oil furnaces
Thread Content
Calculate the heat exchange area for recovering the waste heat from the flue gas of a heat transfer oil furnace. Parameters: flue gas volume of 1000 cubic meters, temperature of 260 degrees. The heat is to be recovered using high-temperature soft water, with the temperature of the soft water being around 105 degrees and a flash vapor pressure of 50 KPa. Please help calculate the heat exchange area. Thank you!
The conditions you’ve provided are not sufficient; selection of the appropriate model is necessary, which requires testing various parameters. Only by using heat exchanger selection tools or process calculation software can such calculations be carried out – it’s impossible for an average person to do this calculation.
So let’s see if there are any experts around. . . Dear friends. . . Get moving. . . Not active enough, everyone
It can be achieved using a heat pipe steam generator, with a small size
Based on normal flue gas calculations, with a flow rate of 1000 Nm3/h, an inlet temperature of 260 degrees and an outlet temperature of around 167 degrees, as well as an inlet water temperature of 105 degrees, it is possible to produce 58 kg/h of 0.5 MP saturated (151°C) steam. 88 heat pipes are required, with a heat exchange area of around 36 m2. The pressure drop is approximately 40 Pa, and the heat transfer capacity is 37.3 kW
I see a heat pipe again. What is filled inside the heat pipe? Are there any authoritative data on heat pipe heat exchange?
I just have an issue – the equipment weighs around 2 tons, and its total cost is 50,000. With boiler accessories. Excluding costs for installation, interfaces, etc., at 130 yuan per ton of steam, the equipment investment can be recovered after approximately 10 months of operation
Upstairs, are you satisfied with this plan?
50KPA pressure, right? Isn’t 0.5MPA a bit too high?
I thought 50kPa was a typo; if it really is 50kPa, it will be impossible to control the water inflow. A heat pipe is an efficient heat transfer element, sometimes referred to as a \"superconductor of heat.\" It has many advantages, especially in areas such as gas-to-gas heat transfer and gas-to-liquid heat transfer.
