The flameless heater system includes an energy source comprising a diesel engine configured to create volumes of air, a hydraulic system to control engine loading for heat generation and for air moving, and a control system, operatively coupled with the energy source and the hydraulic system to control at least one of a speed of the diesel engine, a loading of the diesel engine, or a fan speed.

A heat-generating assembly (1) includes at least one airflow generation device, air supply which is fluidically connected to the airflow generation device, and at least three heating devices, each having an air inlet connected to the air supply, and a reheated air outlet. The airflow generation device and the heating devices are controlled in that the heating devices are distributed along at least one perimeter line, and in that each perimeter line section which contains three adjacent heating devices is curvilinear.

According to various aspects, exemplary embodiments are disclosed of blow through direct fired heaters including evaporator coils and/or energy recovery ventilation.

Outdoor power equipment includes a frame supported by a plurality of wheels and an air heating system. The air heating system includes an air inlet, an air outlet, a heating device configured to heat the air between the air inlet and the air outlet, and an adjustable duct connector fixedly coupled to at least one of the air inlet and the air outlet. The adjustable duct connector includes a base plate, a ring arm slidably coupled to the base plate, and a handle rotatably coupled to the base plate and the ring arm. Rotation of the handle selectively transitions the ring arm between a first position proximate the handle and a second position arranged further from the handle. The adjustable duct connector further includes a locking mechanism configured to secure the ring arm in the first position and the second position.

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 heating system including at least one louver coupled with the housing of a heater including a blade and end caps on the blade for holding each louver in a fixed position during operation of the heater assembly, but also releasing the louver for adjustment in positioning relative to the axis of rotation of the louver to change air flow direction or other characteristics as desired.

A heater including a cylindrical housing with an inlet end, an outlet end, and an axis extending between the inlet end and the outlet end. A combustion chamber is positioned at least partially within the cylindrical housing. A base is coupled to the cylindrical housing. A user interface is operable to control combustion within the combustion chamber. The axis is positioned between the base and the user interface.

Disclosed is a portable hot air generator apparatus which includes a handle and a body forming a Venturi and, furthermore, a damping system between the handle and the body.

The invention relates to a heating device for heating air, having a primary heat source (10) and a heat exchanger (2). The heat exchanger (2) has an interior space (22) for receiving the primary heat source (10) and transfers thermal energy generated by the primary heat source (10) to the air. The heat exchanger (2) includes a holding element (21) for receiving an electric heating element (11) as a secondary heat source (2). The heat exchanger (2) consists of a first heat exchanger unit (201) and a second heat exchanger unit (202).

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.
