Utilization of waste heat in coking plants
Thread Content
Currently, the environmental situation is severe, **with stricter requirements imposed on the exhaust gas emissions from coking plants; there are regulations in place to control the emissions of sulfur dioxide and nitrogen oxides. Therefore, to reduce costs, making good use of waste heat is particularly important. However, the steam generated by the flue gas desulfurization waste heat boiler is supplied to users at a pressure of 0.4 MPa and a temperature of around 140 degrees. Due to these low pressure and temperature levels, it does not meet the requirements of the manufacturing process, making it practically useless; although it appears to be a source of energy, it is very difficult to utilize. Friends, is there any good solution? What methods can be used to increase steam pressure and temperature in order to compensate for the energy lost during transportation?
Should the steam produced by the waste heat boiler be reheated? What method should be used? High costs are also practical.
Use a steam jet pump to mix it and obtain medium-pressure output, or use it on-site within the plant
Is the consumption of high-pressure steam high?
It’s still relatively high; mainly, medium-pressure steam is useful in various applications. We have carried out modifications in this area; if you are interested, please send me an email to describe your current situation: mysmia@126.com
If your heating demand is not high, you can use this low-grade heat source to generate electricity, thereby earning money by connecting it directly to the power grid.
It can be used for both heating and domestic hot water systems, right?
I have an inorganic chemical engineering technology that enables the large-scale utilization of waste heat; it is safe and pollution-free. The investment required ranges from 1 million to 100 million. With an investment of 20 million, annual profits can reach 80 million, while profits can reach 100 million if there is available waste heat. Those interested should contact myben@126.com
What is the exhaust temperature after heat exchange? By increasing the number of heat exchangers, it is possible to reduce this exhaust temperature, thereby improving the efficiency of waste heat recovery and raising the temperature of the steam produced
