How to Customize Your Combustion Solution with Forney’s PAF (Parallel Air Flow) Burner

In the southern US states, peak demand for power generation typically runs from May to September due to people needing to cool off from the summer heat. In the northern US states, higher power generation demands peak during winter when people are looking to warm up their homes.

For plant supervisors and instrumentation/control technicians, these are their most stressful seasons. Their equipment must be running well and generate enough power to meet the increased demand loads while keeping emissions within regulated limits.

This problem is especially significant for plants with medium to large steam boilers aiming for gas conversion while meeting the strict emission requirements.

These operational strains can degrade and significantly shorten the lifespan of your plant equipment. If coupled with insufficient maintenance measures, this results in utility downtime, higher Loss on Ignition (LOI), and higher emissions.

Left unchecked, you’re looking at state fines, federal fines, and bad publicity due to higher emissions on top of the growing revenue losses your plant is suffering every single day. If this trend continues, layoffs and even more strained plant operations can quickly become a reality.

Most plants will opt for frequent, repeated equipment repairs instead of replacement with a better, more long-term solution. Some will even pay the fines and hope the press won’t catch on.

Here at Forney, we understand this draining cycle of plant operations. To help plant managers and operators like you get out of this cycle, our engineers developed a custom solution that allows you to meet your load requirements without worrying about emission and maintenance.

The result is our custom-designed Parallel Air Flow (PAF) Burners.

Forney PAF Burner

The Forney Parallel Air Flow (PAF) Burner is our answer to achieving generation demands without compromising emissions and potential maintenance issues in the most convenient way possible.

Each of our PAF Burners is custom-engineered for a wide range of heat inputs while providing the flexibility of firing various fuel types. Whatever your plant’s heat or fuel type requirements are, we have a PAF Burner made just for your plant.

This ensures less utility downtime, lower LOI, and more importantly, decreases the probability of revenue loss caused by failure to hit target loads on demand.
