In production management------Steam consumption and cost control--Full utilization of waste heat recovery
Thread Content
1...Many enterprises use steam as a heat source in their production processes for process heating/heat exchange. However, for the discharge and control of steam condensate after heat exchange, most enterprises still use traditional steam traps for this purpose. But this has invisibly caused a leakage of at least about 5% of the steam volume. The more steam traps are used in a plant, the greater the amount of fresh steam (unconditioned) that leaks. 2... When high-temperature condensate is discharged into ponds in a low-pressure or atmospheric pressure environment, a large amount of flash vapor is generated. This not only wastes this heat but also has a severe negative impact on the production environment (with smoke and vapor everywhere). The heat contained in this flash vapor is very valuable; if it can be recovered, it would bring great benefits to the enterprise. Currently, the price of steam in the market is around 200 yuan per ton. If one ton of flash steam can be recovered and reused, the company will be able to reduce its consumption of one ton of fresh steam. In this way, enterprises not only reduce energy consumption and improve their production environments but also save more energy for society. 3...Currently, many companies in the market are capable of carrying out condensate recovery; they use high-temperature water pumps to transport hot water (at around 60-100 degrees Celsius) to boilers or to replenish water in circulation tanks for use. However, circulating water needs to be cooled using cooling towers; reducing condensate water with such high temperatures to normal levels requires a large amount of electrical energy, which leads to increased energy consumption and raises the production costs for enterprises. In some companies, the hot water has no useful purpose and can only be discharged on-site, resulting in waste and loss of water resources. At the same time, environmental protection authorities charge companies for the wastewater they discharge, which further increases costs. 4...If a company faces the issues mentioned above and wishes to resolve them in order to reduce production costs, it can get in touch with me. Our company has been specializing in this industry for over a decade; we have provided professional services to hundreds of companies. Our constant pursuit is to help businesses save energy and reduce costs, thereby contributing to the creation of wealth for society!
I think there are many organizations that need it; too many have been working in the energy sector in recent years
Yes, China is a country with high energy consumption, so it is essential to save energy and reduce consumption. Environmental pressures require that enterprises avoid releasing steam, and it is also necessary to improve the conditions at the production sites. Saving energy and reducing consumption, as well as lowering the unit cost of products, is also crucial for enhancing a company’s competitiveness. Saving energy and reducing consumption for enterprises, as well as accumulating wealth for society, is the path to green and sustainable development.
There’s also a direct way, which is to sell hot water to bathhouses
Buying hot water for bathhouses is now the most basic form of energy-saving approach adopted by many companies. If a company has its own boiler, it’s most sensible to recycle the hot water back into that boiler. If the company relies on steam supplied by a power plant, and that plant does not recycle the condensed water, then the only options are to dispose of it or sell it as hot water. Nowadays, bathhouses are not allowed to have boilers, as their hot water resources are very limited. This can also only utilize the sensible heat of water, but more heat is lost to the air in the form of flash vapor. If this portion of the flash vapor can be reused, it is possible to save the corresponding amount of primary steam. Then its value is very high.
