Power & Steam Boiler

Boilers are required to provide the power and steam needed for many stages of the kraft process. Efficient burner control ensures reduced fuel costs and lower emissions.

Efficient boiler operation depends upon optimizing the combustion reaction between oxygen (from air) and the fuel used. An ideal ratio between the two ensures safe and efficient operation with minimal emissions.

High temperatures are used for drying and cooking stages, and for the recovery process. Analysis of the flue gases from the boilers used is needed to ensure efficiency and regulatory compliance.

We provide proven solutions for monitoring gases in power and steam boilers. These trusted measurement technology and specialized designs for high-particulate conditions.

    Combustion control

    The key to combustion efficiency is to find the optimum ratio between air and fuel in the combustion reaction. This requires, at the minimum, accurate monitoring of oxygen, and also benefits from additional measurements: combustibles (for process optimization) and methane/hydrocarbon (for safety).

    Recovery Boilers

    Recovery boilers are used to recover the chemicals for white liquor from black liquor. The black liquor is burned, generating heat use for power/steam. Although a difficult application, combustion control is critical for burner operation.
