A burner includes a housing, a fan, a burning head and an ignition mechanism. An air inlet of the housing and an input end of the burning head form a pressure equalizing cavity. The ignition mechanism is arranged at an output end of the burning head. The burning head includes a main frame and at least one stable burning isolation strip, an interior of the main frame is divided into at least two ventilation areas by the stable burning isolation strip in a gas channel direction. A plurality of separation mechanisms is arranged in each ventilation area and divide the ventilation area into a plurality of through holes arranged in the gas channel direction, the through holes are used for allowing mixed gas to pass through and strengthening the mixing effect. The burning flame of a burning surface of the main frame can be divided into mutually independent flames by the stable burning isolation strip. The burner can be used in gas stoves, low-nitrogen combustion engines for a gas boiler, gas water heaters and gas heating water heaters.

Processes and apparatuses for heating process fluid in a furnace. Fuel to the furnace is either hydrocarbons or hydrogen. The fuels may be sent to different furnaces or be sent at different times to the same furnace. Furnaces that are configured to receive both types of fuels may have different exhaust paths. An exhaust path for hydrocarbon fuel flue gas includes a carbon capture process zone.

According to an embodiment, a fired heater includes a fuel and combustion air source configured to output fuel and combustion air into a combustion volume, the combustion volume including a combustion volume wall defining a lateral extent separate from an exterior volume. According to an embodiment, the fired heater includes a boiler heater and the combustion volume wall comprises a combustion pipe defining a lateral extent of the combustion volume, the combustion pipe being disposed to separate the combustion volume from a water and steam volume. The fired heater includes a mixing tube aligned to receive the fuel and combustion air from the fuel and combustion air source. The mixing tube may be separated from the combustion volume wall by a separation volume. The fired heater includes a bluff body flame holder aligned to receive a fuel and combustion air mixture from an outlet end of the mixing tube. The bluff body flame holder may be configured to hold a combustion reaction for heating a combustion volume wall. The combustion volume wall may include a combustion pipe. The combustion pipe may be configured to heat the water in the water and steam volume.

A combustor of an embodiment includes: a cylindrical combustor liner; and a fuel nozzle which is provided at one end of the combustor liner and jets a fuel and an oxidant into the combustor liner. The fuel nozzle includes: a plurality of fuel supply passages which each supply the fuel; and a plurality of oxidant supply passages which each supply the oxidant. Flow rates of the fuel supplied to the respective fuel supply passages and flow rates of the oxidant supplied to the respective oxidant supply passages are each individually regulated.

The can combustion chamber includes a casing housing a plurality of cans. Each can includes a wall and a perforated cooling liner around the wall. Cooling liners of adjacent cans have staggered perforations.

In a gas turbine combustor, a sectional shape in a radial direction of either one of an inner peripheral surface of a second inner tube member and an outer peripheral surface of a first inner tube member, in a fitting portion of a crossfire tube assembly, has a plurality of small-curvature portions having a curvature smaller than a reference curvature, the reference curvature being a curvature of a portion at a maximum distance from the center of the sectional shape. This configuration ensures the crossfire tube assembly is cooled, and the Possibility of thermal deformation or fire damage is lowered, without lowering the temperature of a combustion exhaust gas passing through the crossfire tube assembly of the gas turbine combustor.
