#AskGlaston Episode 20: How can I remove white haze?

This week’s questions are referring to white haze, the bow of the glass and the correlation between connected power and energy consumption. The questions are:

  1. How can I remove white haze?
  2. The size of our tempering line is 7 x 4 ft. When we move beyond 7 ft in length, the bow is uncontrollable no matter how many settings we have tried. What should we do to fix this issue?
  3. Is there a correlation between connected power and energy consumption?

How can I remove white haze?

White haze can be caused by several reasons. There is no one single solution for each and every case. We have step-by-step instructions on how to figure out the root cause of the problem and act accordingly. Please read more from the link below:

Killing the glass ghost: how to eliminate white haze from tempered glass?

The size of our tempering line is 7 x 4 ft. When we move beyond 7 ft in length, the bow is uncontrollable no matter how many settings we have tried. What should we do to fix this issue?

Based on the descriptions given in the question, we can presuppose that the problem is coming more from the cooling section of the tempering line. This means that there might be blocked quenching nozzles or some other issue, which is causing uneven cooling pressure distribution throughout the quench, making the glass bend. The problem can be solved by either fixing the furnace or checking and cleaning the cooling section.

Is there a correlation between connected power and energy consumption?

The connected power and energy consumption of a tempering line has no correlation whatsoever. Higher connected power doesn’t have a direct effect on the energy consumption. Usually, higher connected power means more control of the tempering line, which actually means lower energy consumption.
