An apparatus and method that enables a single person to remove and replace a part, for example a burner housing, from an industrial piece of equipment such as oilfield equipment. A base of the apparatus attaches, either removeably or permanently, to a portion of the equipment such as an exhaust stack, that is above the part. The apparatus has a plurality of arms which swing out from the base, including a beam which is rotated to be aligned with the part. Straps attached to the beam are tightened around the part, and the arms are then extended to remove the part from the equipment.

A burner sub-system, a furnace comprising the same, a fuel combustion process and steam cracking process carried out in the furnace. The burner sub-system comprises a barrier wall segment between the burner tip and the flue-gas recirculation (“FGR”) duct, effectively blocking direct gas flow between the burner tip and the FGR duct opening, but without encircling the whole burner tip. The presence of the partial barrier wall has the advantage of preventing the temperature inside the FGR duct from becoming too high, while achieving low NOx emissions from the combustion process without overheating the burner tip because of reduced amount of heat reflection to the burner tip compared to an annular barrier wall. The invention is particularly useful in furnaces where hydrogen-rich fuel gas is combusted.

A gas furnace includes a mixing pipe through which a mixture formed by mixing fuel gas and air flows; a burner assembly that generates combustion gas by burning the mixture that passed through the mixing pipe; and a heat exchanger through which the combustion gas flows. In this case, the burner assembly includes a burner in which flame generated when the mixture is burned is seated; and a mixing chamber that mediates delivery of the mixture from the mixing pipe to the burner, thereby significantly reducing NOx emission.

A cooktop and appliance is provided that may include a first hob zone having a fixed gas receptacle, a first interchangeable burner, a second interchangeable burner, and a first gas flow switch. The first interchangeable burner may be selectively positionable at the first hob zone and define a fuel output area. The second interchangeable burner may also be selectively positionable at the first hob and may define a fuel output area smaller than the fuel output area of the first interchangeable burner. The first gas flow switch may be disposed at the first hob zone to selectively engage one of burners. The first gas flow switch may include a valve upstream of the fixed gas receptacle to selectively restrict gas flow upon engagement of the first gas flow switch with one of the first interchangeable burner or the second interchangeable burner.

A high efficiency heating apparatus for heating fluids and cooking mediums, such as oil or shortening within a fryer, includes a natural draft (non powered) combustion chamber that is affixed to an exterior surface of a fry tank.

A burner assembly includes a burner box that defines an enclosure that has a burner plate opening. A mixing tube is in fluid communication with the burner box through a mixing tube opening that extends through the burner box. A baffle creates an enclosure that at least partially separates the mixing tube opening from the burner plate opening.
