One or more techniques and/or systems are disclosed for a heating device may comprise a control assembly having a self-contained, on board power supply. A control unit may control the operation of the heater and the power supply may comprise a first power source in electrical communication with the control unit, wherein the control unit controls the operation of the first power source to selectively supply electrical power to at least a portion of the heating device; and, a second power source in electrical communication with the control unit, wherein the control unit controls the operation of the second power source to selectively supply electrical power to at least a portion of the heating device.

The gas turbine combustor includes a swirler lip on the air hole plate periphery, protruding toward a chamber, and a spring seal in an area for fitting the liner and the plate/lip. The spring seal has an air hole for passage of part of the combustion air introduced in the gap between the outer periphery of the air hole plate and the liner. The swirler lip has an air hole which introduces part of the combustion air passing through the spring seal air hole into the chamber. The liner has an air hole facing the spring seal air hole, to introduce part of air from outside the liner into the gap between the outer periphery of the air hole plate and the liner. A turn guide for rectifying a combustion air flow is provided at the liner end portion on the side for fitting the liner and air hole plate.

A flameless industrial air heater comprising: a combustion engine having a drive shaft and a combustion exhaust gas conduit to direct hot exhaust gases away from the engine; a mixing chamber having an air inlet and being in fluid communication with the exhaust gas conduit to mix the hot exhaust gasses with air flowing into the mixing chamber to produce a warmed air stream; and a compressor connected to the drive shaft and being driven thereby, the compressor being downstream of the mixing chamber to receive the warmed air stream and to pressurize the warmed air stream for delivery to applications requiring heating.

A liquid fuel air heater comprises a housing defining a motor housing portion and a grip portion extending from the motor housing portion. An electric motor is positioned in the motor housing portion. A combustion chamber is at least partially positioned within the motor housing portion. A fan is driven by the motor when activated for generating an axial airflow through the combustion chamber. A battery pack containing a plurality of battery cells connected to each other in a series or parallel arrangement is removably coupled to the grip portion of the housing for supplying power to the motor.

The present invention relates to a boiler with a heating blower, the boiler being able to improve heat exchange efficiency without an additional boiler. According to the present invention, there is provided a heating blower that supplies high-temperature hot wind to a flame guide tube outside a storage tub, so it is possible to improve heat exchange efficiency of the flame guide tube and flue tube without an additional boiler.

A heating device, in particular a gas-heating system, including a housing structure and an external housing, the external housing having at least one sidewall and at least one cover, which are able to be fixed in place on the housing structure. The at least one cover is developed to position the at least one sidewall in at least one direction in space relative to the housing structure. A method for mounting a heating device is also described.

A heater including a housing, a heater unit, a control interface, and a fan unit. The housing includes a base. The heater unit is supported on the base and includes an ignitor mechanism and a heater element having an external surface configured to emit heat. The control interface is supported on an exterior of the housing and includes an actuator operable by a user. The fan unit is coupled to the base or the heater unit and is positioned to induce an airflow through the heater unit within the heater element to heat the airflow. The fan unit includes a fan shroud having an air outlet to direct the heated airflow radially outward.

A portable forced air heater including a housing, a heating element located within the housing, a sensor configured to sense a characteristic of the portable heater, a communications device configured to communicate with an external device, and a controller having an electrical processor and memory. The controller is configured to receive, from the sensor, the characteristic of the portable heater, and output, via the communications device, a signal indicative of the characteristic of the portable heater to the external device.
