Graver Technologies provides filtration solutions to optimize the quality, productivity, and economics for paper mills.
Filtration is an essential part of the manufacturing process for the pulp and paper industry, who requires innovative technologies to ensure product quality, consistency, and affordability. Protection of equipment such as valves and pumps and managing incoming raw water quality or bleaching chemicals and additives is critical to minimizing downtime, reducing the cost of maintenance, and assuring high productivity levels. Whether it is cooling water filtration, process water filtration, spray nozzles protection, pump seal protection, or RO prefiltration, Graver Technologies provides a filtration solution to allow manufacturers to meet the quality, productivity, and economics of their process.
How often should gas turbine filters be replaced?
This depends on the environment and filter type; however, pre-filters are changed every 3–6 months, while final filters may bechanged once in a year or two. Monitoring pressure drop is key to determiningreplacement timing.
What factors affect the operating life of a gas turbine filter?
Here are some factors:
How do I know when a filter needs to be changed?
Differential pressure across the filter is animportant aspect in this case. If it increases beyond the set threshold, thefilter may be clogged or need cleaning or replacement.
What is pressure drop and why does it matter?
Pressure drop is the resistance to airflow through afilter. A high-pressure drop reduces turbine efficiency and increases energycosts. Selecting low-resistance filters helps improve performance.
