With our partners, we developed the Pyroinc 320BL especially for use in recovery boilers (black liquor boilers). The air -cooled probe has a diameter of 70mm only and a length of either 906mm or 1526mm. The measuring temperature range startes from 600 ° C to 1450 ° C with a resolution of 320×240 pixels. The opening angle is 74 ° x 55 °, which is of course kept free of dirt by a patented air flush. In order to get a maximum of information from the online image, this version of the Pyroinc will of course also work with a flame filter. In addition, an automated system is periodically cleaned the boiler opening. You can find out more here: Pyroinc 320BL/
