Abstract: A burner includes an atomizing chamber, a flame tube in front of the atomizing chamber adapted to direct combusting fuel introduced by the atomizing chamber along an interior of the flame tube, and a controller. The controller is programmed to independently control rate of fuel flow to the atomizing chamber, rate of atomizing air flow to the atomizing chamber, and rate of combustion air to the flame tub. The controller is also programmed to perform operations including regulating, based on output of a gas sensor, at least the rate of combustion air to the flame tube to substantially maintain a first predetermined amount of excess air in the flame tube.

Abstract: A deployable facility includes an enclosure that has a first configuration with a first service volume and a second configuration with a second service volume. The second service volume is greater than the first service volume. The enclosure includes a fixed floor, a fixed roof, and a movable wing that is pivotably coupled to the fixed floor. The deployable facility also includes a covering support assembly that is pivotably coupled to the fixed roof. The covering support assembly has a collapsed configuration within the first service volume on a condition that the enclosure is in the first configuration and an expanded configuration within the second service volume on a condition that the enclosure is in the second configuration.

Abstract: A deployable kitchen includes an enclosure, a lateral wall, and then exhaust assembly. The exhaust assembly is positioned within the enclosure and is configured to receive a cooking exhaust and a combustion exhaust from an appliance. The exhaust assembly includes an exhaust hood, an exhaust plenum, a blower, an outer duct, and an inner duct. The outer duct is configured to receive the cooking exhaust. The inner duct is positioned within the outer duct and is positioned to receive the combustion exhaust.

Abstract: A deployable kitchen includes an enclosure, an appliance within the enclosure, and a recapture plenum. The appliance includes a housing and a burner unit that is within the housing. The appliance defines cooling passage between the housing and the burner unit. The cooling passage is in thermal communication with the burner unit such that an airflow through the cooling passage establishes an air buffer between the burner unit and the housing. The housing includes a face that defines an outlet of the cooling passage. The recapture plenum encloses the face of the housing such that the recapture plenum receives an exhaust portion of the airflow after the airflow is conveyed through the cooling passage. The recapture plenum is configured to be in fluid communication with a heating vent within the deployable kitchen.

Abstract: An atomizing burner and corresponding method for turning an atomizing burner from an ON state to an OFF state. The burner has independently controllable flows of atomizing air, combustion air, and fuel flow, the burner in the ON state having flow values of burner parameters including flow of atomizing air, flow of combustion air, and fuel flow. The method includes: changing, in response to an OFF instruction, flow of at least one of the flow of atomizing air, combustion air and/or fuel to a lower non-zero value; first discontinuing, after a first period of time since the changing, flow of fuel and flow of atomizing air; maintaining, for a second period of time since the first period of time, flow of combustion air; second discontinuing, after the maintaining, flow of combustion air; wherein the maintaining prevents buildup of excess heat inside the burner during the transition to the OFF state.

Abstract: A burner with a flame detector is provided. An atomizing chamber has an aperture. A flame tube is in front of the atomizing chamber, adapted to direct combusting fuel introduced by the atomizing chamber along an interior of the flame tube. A photodiode circuit is located behind the atomizing chamber. A filter is adapted to filter out signals from the photodiode outside of a predetermined bandwidth. Light from combusting fuel in the flame tube reaches the photodiode through the aperture. The output of the filter indicates the presence or absence of the flame in the flame tube based on at least whether enough light received and converted by the photodiode has a flicker rate within the predetermined bandwidth.

Abstract: A mobile kitchen comprises a housing disposed atop one or more wheel axles and a plurality of appliances disposed within the housing. Each appliance is heated by combustion of a distillate fuel. One or more air channels are disposed about each of the appliances, such that each air channel substantially isolates excess heat from combustion of the distillate fuel from a workspace within the housing. One or more first air blowers are associated with the air channels, and each is adapted to force air through the air channels and vent the excess heat to the exterior of the housing. One or more second air blowers are coupled to the housing, and each second air blower is adapted to vent a predetermined volume of air from within the workspace at least once per minute.
