A pressure-type alcohol stove includes a stove body, an upper cover, a pre-heating pipe, and an automatic liquid-feeding device, wherein the upper cover is arranged on the stove body and is matched with the stove body to form a vaporization cavity, the pre-heating pipe penetrates through the upper cover and has a bottom end located in the stove body and a top end partially stretching out of the upper cover, a pre-heating cavity is formed around the pre-heating pipe, spirally-distributed spray holes are formed through the upper cover, air jet holes used for air jetting and pre-mixing are formed through an upper part of in the pre-heating pipe.

The current invention discloses a method of controlling the flow rate of a heavy fuel oil in a fluid transfer apparatus having a point of use outlet to a boiler. It not only controls the flow rate of the fuel oil directly, but also indirectly control the viscosity of the fuel oil without measuring its viscosity. It relies on combustion curves established during the commissioning period using a typical fuel oil at a predetermined trim heater temperature. During normal operation, it sets the flow control valve according to the combustion curves, measures the flow rate and compares to the flow rate target. Instead of using the flow rate measurement feedback to control the flow control vale, it modulates the trim heater to vary the viscosity to arrive at the desired flow rate.

A fired heater has two cells segregated by an insulative wall. A first plurality of burners are located in the first cell and a second plurality of burners are located in the second cell. A radiant tube extends from the first cell to the second cell for carrying a fluid material through the heater to heat the fluid material. The flow of fuel to the burners in either the first cell or the second cell can be terminated to accommodate lower heater duty when demand is lower.

Compared with traditional alcohol stoves, the alcohol stove of this invention has higher power and efficiency.

A turbocharged burner has a burning unit and a turbocharger. The burning unit is installed with a fuel bucket for storing fuel and a burning chamber having a tubular shape, and interior of the burning chamber is installed with at least one nozzle. At least one fuel tube coupled to the fuel bucket is disposed at each nozzle, and the turbocharger is coupled to the burning chamber. Under the reaction of the turbocharger, the gas fluid of the burning chamber is increased, a flowing speed and a flowing flux of the gas fluid are increased, and thus the burning further entirely achieves the objective of increasing fuel burning efficiency.

A heating system includes a closed pipe for flowing kerosene, the closed pipe including lengthwise conductive ridges on an inner surface; a pump being in fluid communication with kerosene; heating assemblies each including an insulation cylinder put on a portion of the closed pipe, and a heating coil wound on the insulation cylinder for heating the kerosene; and a plurality of electric power sources each electrically connected to the heating coil.

A system for providing ignition and pressurization of hypersonic vehicles is disclosed. The system combines the pressurization, barbotage and ignition functions into a single system saving mass and volume and simplifying the hypersonic vehicle plumbing. A monopropellant fuel such as Tridyne is used to pressurize a fuel tank, warm the fuel as it enters fuel injectors, and provide barbotage of the fuel just prior to its injection into a combustion chamber.

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.
