afgasstroom

Afgasstroom is a term used in Dutch engineering to describe the flow of exhaust gas away from a device, reaction chamber, or enclosure. It refers to the rate at which gas exits the system and can be expressed as a volumetric flow (for example, cubic meters per hour at specified conditions) or as a mass flow (kilograms per hour). The afgasstroom is a key process variable in the design and operation of ventilation, combustion, and emission-control systems, and it interacts with gas temperature, pressure, and composition.

Measuring and controlling the afgasstroom involves several methods. Common instruments include differential-pressure flow meters, rotameters, turbine meters, and mass flow meters. In practice, measurements are often referenced to standard conditions to allow comparison across equipment and processes. Factors such as pipe geometry, bends, leaks, and potential choking at high pressures can affect accuracy and require proper calibration and sampling locations.

Applications of afgasstroom span industrial and environmental contexts. In combustion systems and furnaces, it helps maintain safe temperatures and efficient fuel use. In exhaust systems and incinerators, it determines the rate at which pollutants are removed. In building HVAC, it ensures adequate ventilation and contaminant removal. Regulatory considerations frequently govern acceptable afgasstroom rates and permit monitoring, particularly when toxic or corrosive gases are involved.

Etymology and usage: the term is of Dutch origin, combining afgas (exhaust gas) with stroom (flow or stream). It is used primarily in technical documentation, process control, and engineering discussions related to gas handling and emissions.
