Heat recovery and mechanical chimney draught control for can manufacturing

Can Manufacturing

The heat recovery process gives companies the option of exploiting energy resources to their full potential. Most companies try to better the efficiency of their production process in order to reduce production costs, and heat recovery systems are a good option to do just that.

The process works by identifying heat sources in the production plant and capture waste heat using strategically placed heat exchangers. In can manufacturing, there are several production phases that can emit a lot of heat, which is dissipated into the atmosphere and thereby wasted.

The heat recovery system follows a process of identifying heat sources and converting heat energy into hot water by using heat exchangers. Once the heat has been converted into hot water, it can, among other things, be stored in buffer tanks, where the temperature is maintained.

In can manufacturing, several processes, such as aluminum refining, heat fixation, and rolling are all associated with high heat emission.

In the aluminum refining process, the bauxite minerals are processed and refined in order to produce aluminum.

This refining process takes place at high temperatures, where heat exchangers can be placed in the air stream to capture the waste heat.

The primary heat source that allows for the greatest exploitation is during paint fixation and coating of the cans in the heat fixation oven. The oven emits exhaust gasses at high temperatures, along with steam.

This provides a profitable option for heat recovery. As a result of the high temperatures used during can manufacturing, recovery of waste heat is associated with huge advantages.

For instance, the captured heat energy can be reused in the production process, for heating, or for cleaning purposes in the production plant. The primary advantage is production cost savings by reusing waste heat, which enables the production of cans at a cheaper cost.

As far as exhaust gasses that are discharged in several cases, e.g. from the heat fixation oven, our mechanical chimney fans enable a reduction in energy consumption. exodraft’s chimney fans always maintain a consistent draught, thus reducing energy consumption and making the production result uniform.

The first step in the process toward new energy-friendly solutions is for our team of experts to visit your production plant, so we can use readings, etc. to establish the recovery potential using our OptiCalcHR software and clarifying how much you can save by installing our system. We also provide a feasibility plan that helps you make a well-informed decision.

After analysis of the entire production process, we give you advice about which exodraft solutions are best suited for your company. Heat recovery doesn’t just help your factory reduce cost, but by reducing energy consumption, it also helps reduce CO2 emissions, thus resulting in a positive environmental impact.
