Thermal conductivity dropped back to use for washing and staining. the water temperature in the process and staining have value about 60-100 ° C by using steam mixed with water in the tank directly or bring steam to heat exchange through coil pipe heat at these high temperature. In most cases, it will be released into the pond water treatment by combining this waste heat with a cold water.There are only some of factory that bring waste heat is reuse for a new job.
