A first cavity between the regenerative section (40) and the inner wall of the metal shell (5) is divided into a first inlet chamber (6) and an exhaust chamber (8) by an inlet partition plate (7), a second cavity between the oxidation section (41) and the inner wall of the metal shell (5) is divided into a second inlet chamber (22) and a mixing chamber (20) by a partition plate (21) for averaging gas, and a plurality of gas nozzles (28) are provided on the partition plate (21) for averaging gas. An internal heat exchanger (35) is arranged within the heat exchange chamber (14), and a heat exchanger inlet (16) and a heat exchanger outlet (15) of the internal heat exchanger (35) are respectively connected with a boiler drum (18). The first inlet chamber (6) is connected with an inlet (1) of the ventilation gas through a proportional control valve (38), the second inlet chamber (22) is connected with an inlet (31) for extracting the low-concentration gas through a proportional mixer (33), and the proportional control valve (38) is connected with the proportional mixer (33) through a connecting pipeline (36). The two ends of an inlet preheating pipe (9) on the honeycomb ceramic oxidation bed (13) are respectively communicated with the first inlet chamber (6) and the mixing chamber (20).

A gas combustor comprises a gas container, a fuel gas controlling device, a housing, a piezoelectric device and a combustion device. The safety switch is slidably disposed in an opening of the housing and includes a slide member, a fasten member and a passive member, adjacent surfaces of the slide member and the fasten member are disposed with a connecting mechanism and a radial sliding mechanism, thereby enabling the slide member to perform a radial sliding motion towards the left or the right at the front end of the fasten member; a rear surface of the passive member is formed with a lock tenon abutted against a block tenon of the fuel gas controlling device, thereby forming a lucked status; when the slide member is pulled towards the left or the right, the lock tenon is released from the block tenon, thereby forming an unlocked status.

A gas treatment plant (3) for treating an industrial waste gas comprising carbon dioxide comprises an oxyfuel boiler (100) and a pipe (109; 122; 180) arranged for forwarding the industrial waste gas to the oxyfuel boiler (100) and injecting the industrial waste gas into the oxyfuel boiler (100) to participate in the combustion process occurring in the boiler (100) to cause oxidation of at least a portion of the content of at least one oxidizable substance of the industrial waste gas. The gas treatment plant (3) further comprises a gas cleaning system (108), and a pipe (126) for forwarding a carbon dioxide rich flue gas generated in the boiler (100) to the gas cleaning system (108) for being cleaned therein, such that an at least partly cleaned carbon dioxide rich flue gas is formed.

One object of the present invention is to provide a burner for producing inorganic spheroidized particles which can efficiently melt and spheroidize even organic powder with a large particle size distribution. The present invention provides a burner for producing inorganic spheroidized particles, including; a raw material powder supply path configured to supply inorganic powder as raw material powder; a first fuel gas supply path (3A) configured to supply a first fuel gas; and a first combustion-supporting gas supply path (4A) configured to supply a first combustion-supporting gas; wherein the raw material powder supply path includes: a first supply path (2A) configured to extend in an axial direction of the burner (1); a first collision wall (2D) configured to be located at the top of the first supply path (2A); a plurality of second supply paths (2B) configured to be branched from the top of the first supply path (2A), and extend radially from the center of the burner (1); one or more dispersion chambers (2C) configured to be located at the top of the second supply path (2B), and have a space in which the cross-sectional area is larger than the cross-sectional area in the second supply path (2B); and one or more raw material ejection holes (2a) configured to communicate with the dispersion chamber (2C).

A gas-fueled heater can have a housing with pressure regulators, a control valve, a fluid selection valve and a burner positioned therein. The pressure regulators, control valve, fluid selection valve and burner can be configured to combust a fuel to create heat. The housing can include a number of holes passing therethrough to control access to the various components.

A gas water heater includes a water tank, a combustion chamber, a burner, a heat exchanger tube at least partially within the water tank, and a fan. The burner receives fuel gas and primary air from a first air-supply channel to create a primary air-fuel mixture for combustion in the combustion chamber with secondary air. The primary air-fuel mixture has a gas concentration above the upper explosive limit of the fuel gas. Secondary air is supplied through a second air-supply channel to the combustion chamber. The secondary air creates a low excess air ratio (e.g., below 1.5) for combustion in the combustion chamber. A totally sealed channel is defined from the air inlet of the fan to the heat exchanger tube.

A furnace which receives input information of various sources, distinct from a thermostat, and can vary heat output based on the input information. Examples of input information include without limitation exhaust temperature, temperature near the heat exchanger compartment, temperature sensors within the housing, air pressure, motor RPM, and/or motor amperage. Heat output may be varied by one or more of combustion fan output, fuel flow to burners, combinations or other ways.
