Combustion Air Requirements:The Forgotten Element In

Temporary air intakes such as open boiler room windows can be closed (and often are when persons in the boiler room are feeling cold), cutting off the boiler's air supply. When the combustion air supply is closed off, the fire starts to smoke as the air supply is exhausted. Incomplete combustion occurs and carbon monoxide is generated.

Optimization of Secondary Air Distribution in Biomass

Abstract: This paper deals with a use of CFD modelling for optimization of supply of secondary combustion air in the two-chamber biomass boiler combusting very wet biomass (capacity ca. 200 kW). Objective of the analyse is to observe the impact of diameter of a secondary air supply pipe and air flow velocity on mixing of the secondary air with flue gas in the combustion chamber.
