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 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 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.
