Paper Mill Optimizes Bleaching of 4% Kraft Stock
The mill experienced uneven heating and rough operation with its direct contact steam heater which was an adaptation of a static mixer. Inadequate condensing caused very rough operation that cracked the mixer and start-up noise and vibration compromised the mixer and associated piping and supports.
The solution was to install an Industrial Hydroheater® in-line. Because the Hydroheater was properly sized for the flow rates, vibration stopped immediately after installation.The Kraft stock temperature is precisely controlled within 1°F (0.5°C).

Unlike heat exchangers or spargers, the Hydroheater is designed only for your process conditions and unique application. We need to know a few things about your conditions, such as temperature range, steam pressure, and flow rates to size a heater specifically for you. When you click on our application data sheet and fill in the information, we will contact you within one business day. After an initial conversation with a sales representative or one of our engineers, we will then provide you with a custom quote for the Hydroheater best suited for your process.
Yes, I want to save energy and have more control using direct steam injection. Please complete the Application Data Sheet which helps us understand your process conditions such as fluid density, flow rates and temperature parameters.
