The present invention discloses an air energy boiler and belongs to the technical field of energy conversion. A crankshaft of the boiler is fixed at the output end of a rotating unit. The crankshaft is provided with at least one bulge. A driving piston of each conversion assembly is arranged in an air cavity in a reciprocating motion. The driving piston divides the air cavity into a first cavity and a second cavity. A wrist pin is arranged in the second cavity, and the wrist pin is fixed and connected with the driving piston. Both ends of a piston rod is rotatably connected with the wrist pin and the corresponding bulge respectively. The first cavity is provided with an air intake. Multiple heating pipes are in communication with the first cavity at one end and stretch into the boiler body at the other end. The boiler body is sealed and stores water, and the boiler body is provided with a steam outlet, wherein the steam outlet of the boiler body is connected to various terminals through the use of pipelines. Since air is used as the heat source, no conditional limitations exist for installation, and it is safe to use and saves energy and electricity.

Disclosed is a high-temperature hot air blower capable of gathering energy and generating heat, including a machine housing (1) provided therein with a side wall (12) of a machine inner-side channel; an energy-gathering heat generator (13) is disposed on the side wall (12) of the machine housing inner-side channel and includes a heat generator transmission protective cover (14), a heat generator friction heat-generation body (15) and a heat generator heat-insulation isolation wall (16); the heat generator transmission protective cover (14) and the heat generator heat-insulation isolation wall (16) are respectively arranged on two sides of the heat generator friction heat-generation body (15), and are respectively in fit connection with the side surfaces of the heat generator friction heat-generation body (15); and the energy-gathering heat generator (13) is in fit connection with the side wall (12) of the machine housing inner-side channel via the heat generator heat-insulation isolation wall (16).

A dual heating process is performed in the absence of an open flame. Heat is created by a rotating prime mover(s) driving a fluid shear heater. Heat is also collected from a cooling system of the prime mover, and from any exhaust heat generated by the prime mover. The heat energy collected from all of these sources is transmitted through heat exchangers to a fluid where heat energy is desired. The fluid being heated may be glycol or air, depending on the type of heat desired.
