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.

The invention discloses a high efficiency combustion control system and a method thereof. A high-efficiency combustion control system includes a gasification unit, a gas remixing zone coupled to the gasification unit, a combustion unit coupled to the gas remixing zone; a first gas detecting unit disposed in the gasification unit; a second gas detecting unit disposed in the remixing gas region; and an air supply unit coupled to the gas remixing zone. The first gas detecting unit and the second gas detecting unit detect the concentration of a specific gas of the first gaseous fuel or the second gaseous fuel respectively. And air is supplied to the liquid fuel or the first gaseous fuel according to the gas concentration, so that the gasification rate is changed, and the calorific value is changed accordingly to obtain the optimal calorific value and the optimal combustion efficiency.

A vaporization pipe for a kerosene lamp has an oil tube, a thermally conductive tube, and a first passage. The oil tube is made of steel and has a vaporization jet on a top of the oil tube. The thermally conductive tube is mounted in the oil tube and forms a first channel. The first passage is disposed between the oil tube and the thermally conductive tube. The steel oil tube can prevent the vaporization pipe from being softened and bent during the preheating of vaporization pipe or burning of the kerosene, and thus a useful lifetime of the vaporization pipe is prolonged. The thermally conductive tube is made of high-thermal-conductivity material for keeping the vaporization pipe with adequate thermal conductivity and improving a burning rate of kerosene. The first passage allows the kerosene to flow upward, preventing the kerosene from being vaporized incompletely because the kerosene is over pressurized.

A nozzle structure of a burner includes: a housing having an exhaust opening penetratingly-formed at an upper surface thereof, and having therein an accommodation space communicated with the exhaust opening; a fuel supply member connected to the housing such that one end thereof communicates with one side of the accommodation space, for supply of liquid fuel to inside of the accommodation space; a fuel supply controller accommodated in the accommodation space so as to be movable up and down, and having a fuel supply micro-control member at an end thereof, the fuel supply micro-control member configured to micro-control the amount of fuel to be supplied, by being selectively inserted into or separated from the exhaust opening as it moves up and down; and a heating pipe connected to two sides of an outer surface of the housing with different heights, so as to communicate with the accommodation space.
