The capture efficiencies of standard exhaust hood for exhaust gas and contaminant generated by cooking on the commercial cooking stove and fryer were measured in case that there is horizontal airflow from the outside of hood. Two kinds of heat sources of natural gas and induction heater are selected. Through the experiments, it is turned out that the capture efficiencies for the electromagnetic cookers are less than those for gas-fired cookers under the side airflow of 0.25 or 0.5 m/s. This is because the plume above electromagnetic cookers are weaker than the plume above gas-fired cookers due to less of heat generation rate.
