Pellet Burning Boiler

Brandelle Biomass Systems’ current initiative is the development of a proficient biomass boiler; the BX series.

The design of the BX boiler is focused on cost effective, efficient delivery of heat for your home or workplace. These objectives will be accomplished through a precise control, featuring versatile fuel options and compatibility with existing heating infrastructure.  To be effective and versatile, a biomass burner must accommodate biomass fuels of different burning characteristics.  The BX boiler accomplishes this through precise computer control of the complete burn process in much the same way modern automobile engines achieve high efficiency with low pollution.

The boiler is designed for use in an indoor, enclosed environment such as a garage, basement or farm outbuilding. Existing exhaust flue, ducting and blower, designed for fossil fuel furnaces, are completely compatible with the BX series. These proven designs are readily available for low cost installations at an undeveloped site or for retrofitting to existing heating systems that are being upgraded or replaced.

The versatility of a universal fuel design enables effective use in diverse geographic locations.  Wood, corn, mustard, oats, wheat, switchgrass and other biomass fuels can be used in this boiler.  This broad range of fuel facilitates use in areas where common fuels are hard to acquire or become expensive.  The available, inexpensive biomass resources in the consumer’s specific location can be used as an effective fuel source.

The most impressive attribute of this boiler is efficiency through precise control.  Current testing yields 85-92% efficiency dependent on the type of fuel in question. This rating is based on calculated BTU values of fuel input versus observed BTU output value.  This extremely high efficiency is made possible by careful monitoring and control of the combustion process via onboard microprocessor. This arrangement is not unlike the computer controlled combustion in your car. Precise measurements of exhaust and core temperature, oxygen levels, thermal efficiency and more are monitored with thermo-couples and advanced sensors, providing continuous feedback to the processor. The unit is supplied with complex algorithms and combustion settings based on extensive testing for several types of biomass pellet fuel. The processor employs these algorithms and ongoing data input to monitor the status of the combustion process; frequent micro-adjustments to various system inputs based on process data enable a consistently high level of burn efficiency.
