Biomass boiler

Biomass boilers are used to create energy in the form of electricity and/or heat from the use of various types of biofuel.

General info

About Biomass boilers

Biofuels offer challenges in order to reach high efficiency and availability. Biofuel normally tends to create gas-side fouling in all parts of the boiler.

About cleaning

Benefits of our soot cleaning systems for Biomass boilers

Reduced steam consumption for steam sootblowing. Saved sootblower steam is used for increasing heat or electricity production.

Lower fuel consumption. Cleaner tubes mean increased heat transfer and efficiency.

Lower and more stable differential pressure. Infrasound cleaning reaches areas that are not accessible to conventional soot cleaning systems. This means higher availability of the boiler and lower load on ID/FD fans.

Fewer and shorter outages for manual cleaning. With improved cleaning effect you can obtain higher availability and fewer man-hours spent.

Increased lifetime of heat exchangers. By reducing or eliminating steam sootblowing or shot cleaning, the lifetime of heat exchangers is prolonged. Infrasound cleaning is a non-abrasive cleaning method that does not wear on heat exchange surfaces or catalyst elements and does not contribute to corrosion or erosion. Using our optimized steam sootblowing also reduces wear since steam is supplied only half the time.

Moelven Sawmill, Edane Sweden

A case study and results from our infrasound cleaning installation on a Biomass boiler at Moelven Sawmill. At Moelven Sawmill a Compressed air sootblowing is installed but is relatively weak due to nozzles being installed on the turning chamber between the two tube passes, far from the inlet of the first tube pass where most of the deposits are found.

Perstorp Fjärrvärme P6, Perstorp Sweden

At Perstorp Fjärrvärme, Steam soot blowing was previously used six times per day in the economiser and there were also two unplanned stops per year for manual cleaning. The unplanned stops are costly and are preceeded by an increased differential pressure which increases the flue gas velocity, leading to increased erosion and uneven flue gas distribution.
