Expert Biofuel Combustion Control

In an effort to shift to sustainable, environmentally responsible energy production, many companies are shifting to renewable biomass and away from burning non-renewable carbon-rich fuels such as coal and oil. Biomass can come from chipped trees (typically the leftovers from lumber or paper production), construction debris, corn stover, switchgrass, dried manure, organic waste from the production of food or ethanol, and many other sources.

Biofuel boilers are also frequently configured to burn waste streams that aren’t renewable, such as MSW (Municipal Solid Waste), TDF (Tire-Derived Fuel), or creosote-treated rail ties. These boilers are often configured for cogeneration (where steam is run through a turbine to generate electrical power, then extracted for local heating).

Sometimes these boilers are required to act like a thermal oxidizer to ensure organic pollutants are fully combusted.

If you’re regularly working with boilers or controlled combustion reactions, we’d love to hear from you. Our process experts can optimize your process, replace underperforming components, audit your control systems, and much more to ensure that you’re performing at peak efficiency.

Experience With Multiple Boiler Technologies

Since our inception in 1991, Cross Company Process Control Integration has completed well over 75 boiler controls projects ranging in size from small 35 KPPH package boilers up to 500 KPPH industrial boilers. We have experience with multiple boiler technologies, fuels and auxiliary control systems for virtually any hardware platform.

We can help provide the best control option for your application. Our experience ranges from a small PLC or single loop controllers on the small boilers to a fully integrated Distributed Control System (DCS) on the larger applications. In many of these instances, third-party equipment is typically integrated into the control system. Our engineers are highly skilled in incorporating multiple, dissimilar pieces of equipment into a complete package.

Challenges Of Biomass Combustion

Burning biomass in boilers has many challenges over and above the standard challenges from burning coal or oil:

  • The energy density is considerably less, so more mass and volume of fuel must be burned to obtain an equivalent heat value.
  • Water content is often significant, also resulting in more fuel being required to obtain the necessary heat value.
  • A larger proportion of the fuel is typically inert ash, so together with the larger amount of fuel required to obtain the necessary heat, ash production can be far higher than with coal producing equivalent heat.
  • Material handling is more challenging. Biomass is almost always fibrous, which is more challenging to handle than liquid, chunks of coal, or pulverized coal powder. Biomass also often comes in a very wide variety of sizes, and (especially if construction debris is part of the source stream) can contain foreign material such rebar and nails, or good material that is too large, such as whole lumber.
  • Emission controls are challenging to a degree similar to coal, but with different specifics. This is especially true when burning waste streams such as MSW, TDF, and creosote-treated lumber, in which complete combustion must be assured.
  • Biofuel boilers with grates are far more subject to piling, where unburned biofuel builds up on one section of the grate while burning well on other sections. This reduces efficiency, maximum load, and forms clinkers.

Biofuel combustion controls, therefore, have corresponding challenges over and above the standard challenges from controlling the combustion of coal or oil:

  • There is typically far more fuel and ash handling equipment relative to what would be required for the same steam production from burning coal.
  • More auxiliary equipment is often required.
  • Combustion is often less consistent due to varying water content, fuel quality & size, so the amount of air needed at a particular load is much more variable.
  • The flow of biomass into the boiler is typically not measured – and if it is, the heat value is still unknown – so traditional cross-limiting does not work, and flow must be assumed or estimated from belt scales and screw speeds.
