Abstract : The Mobile Kitchen Trailer (MKT) uses 6 M-2 gasoline burners to heat a griddle, range cabinets and cooking racks. These cooking appliances do not currently have any type of chimney or vent, so all combustion products from the burners go into the kitchen. Accordingly, a ventilation system (i.e. equipment vents) was designed, fabricated and tested for the MKT to reduce the probability of clinical symptons that have ranged from mild irritations to possible hypoxia. The equipment vents reduced the carbon monoxide concentration by 89 percent (15.3 ppm to 1.7 ppm), and the percent oxygen was increased by 35 percent (19.4 to 20.4%). The formaldehyde concentration was reduced from 0.37 ppm (exceeding the Threshold Limit Value), to 0.05 ppm, an 86 percent decrease. The equipment vents also reduced the temperature difference between the floor and ceiling by 35 deg F and increased the efficiency of the grill by 53 percent. Combustion products for the M-2 and M-3 burners also were compared. The equipment vents are recommended for use within the MKT as a means of providing a safer cooking environment for military personnel.
