Case Studies

Biomass Combustion Cell

BMA conducted a study on a 25 MW wood chip boiler in order to increase its efficiency, reduce carry-over and eliminate any control irregularity. The boiler uses four Wellon cells. Read more

Boiler Assessment

BMA carried out a study on a tangentially-fired boiler consisting of eight burners arranged on two levels, firing natural gas or fuel oil. The maximum boiler load was 140,000 kg/hr of steam, and the minimum load reached was 27,000 kg/hr. When the load was reduced below this value, control became very difficult. The risk of losing the burners and causing a boiler shutdown increased. Furthermore, the residual oxygen levels at low loads were very high. Read more

Burner and Boiler Component Replacement

BMA has been mandated to carry out a project to retrofit two 300 MW boiler. This project involved the substitution or re-design of some boiler pressure components, the substitution of non-pressure components, the replacement of burners, and the installation of a new DCS. Read more
