O2- and CO-reduction at combustion plants

Due to economic, environmental and technical reasons, it`s necessary to operate combustion plants by means of minimizing energy losses. Essentially, the energy losses of a boiler plant occur by loss of energy through incomplete combustion, through the heat in the exhaust gas, through radiation and through cooling down. This article considers the room for possibilities to improve combustions and discusses how to reduce losses of energy in the exhaust gas. At the established boiler plant of Leiber GmbH in Bramsche, Germany, an existing burner was modified to an effect where the existing O2 trim was retrofitted into a CO control with VSD-control of the air blower.
