SINOx® Exhaust Gas Treatment for Wood-Fired Boilers
Removing nitrogen oxides from the exhaust gases of wood-fired boilers poses a particular challenge for the catalytic reactors used for this purpose. The type of catalyst selected for such applications must be able to handle the sometimes very high particulate contents of these exhaust gases, Especially in a case like this, the fact that Argillon is the only manufacturer of catalytic reactors who can equip its SINOx® systems with either honeycomb or plate-type catalysts means clear benefits for you, the customer: i.e. individual tailoring of the design of the catalytic reactor to your specific needs, safe and reliable system operation without any risk of plugging by deposits and, at the same time, space-saving compact dimensions, a factor which directly translates into lower capital costs.
The exhaust gases produced by wood-fired combustion systems often contain potentially hazardous substances. These can be expected to include, especially when the wood has been chemically treated, high concentrations of alkali and heavy metals, for example. However, Argillon many years of experience in cleaning boiler exhaust gases and our successful development work in connection with raising the resistance of our SINOx® catalysts to poisoning allow us to guarantee long component service lives, even in wood-fired plants. Furthermore, we are always ready to help you out with inexpensive catalyst replacement strategies, and also take back spent material for efficient recycling at no extra cost. Wood-fired boilers often have to fire a fuel that is not homogeneous. In addition to a variety of different woods, a supplementary fuel such as oil is also often employed. Even when boiler load conditions are the same, this may cause variations in emissions and requires a carefully optimized strategy for injecting the chemical reducing agent.
