    摘要: The present disclosure relates to a system and a method for combustion of solid fuels. The combustion system includes burners which supply a mixed flow of fuel and air through a fuel nozzle to the combustion chamber for example of a boiler. The mixed flow of fuel and primary air is supplied to the burner through a duct from a pulverizer where the fuel is grinded to the required finesse. The duct further bends in such a way that one portion is vertical with respect parallel to axis of the boiler 1 A-A is vertical duct and other portion is horizontal duct which is parallel to axis B-B of the fuel nozzle.

    摘要: A heater assembly can be used with a gas appliance. The gas appliance can be a dual fuel appliance for use with one of a first fuel type or a second fuel type different than the first. The heater assembly can include at least one pressure regulator, a housing, and an actuation member. The housing has a first fuel hook-up for connecting the first fuel type to the heater assembly, and a second fuel hook-up for connecting the second fuel type to the heater assembly. The actuation member can control a setting of the pressure regulator based on whether the first or the second fuel hook-up is used.

    摘要: A heating assembly can include a housing with a gas hook-up and an integrated nozzle structure. The nozzle structure can include a first nozzle and a second nozzle. The first nozzle and second nozzle can be concentrically positioned relative to each other. The first nozzle and second nozzle can be adjacent each other. The housing can also include a valve that has a first position in which flow is permitted through the first nozzle but not the second nozzle. The valve can have a second position in which flow is permitted through the first nozzle and the second nozzle.

    摘要: A low NOx combustion method includes steps of injecting reactants into a combustion chamber. A primary reactant stream, including fuel and combustion air premix, is injected from a premix burner port into the combustion chamber. A staged fuel stream is injected into the combustion chamber from a staged fuel injector port adjacent to the premix burner port. A stream of recirculated flue gas is injected into the combustion chamber from a flue gas injector port that is adjacent to the premix burner port and adjacent to the staged fuel injector port. In this manner, the stream of recirculated flue gas is injected into the combustion chamber unmixed with the primary reactant stream and unmixed with the staged fuel stream.

    摘要: The invention relates to a solid fired hot gas generator which comprises a plurality of solid burners for extending the regulating range, which form a multiple solid burner with an enlarged regulating range. A solid feed and a combustion air feed are assigned to each solid burner and with the aid of a dosing means a separate, dosed solid feed to each solid burner is guaranteed. The firing power of the multiple solid burner which is in particular a multiple impulse burner extends from the minimum power of one of the solid burners to the maximum power of all solid burners so that a regulation of all necessary load regions of a plant unit to be supplied is covered.

    摘要: A combustion apparatus 51 includes a plurality of burners 58, a plurality of fuel supply channels 89, a blower 53, an air supply passage 37, and a pressure regulator 56. The burners 58 are divided into a plurality of burner groups 71. The pressure regulator 56 is branched at a portion located immediately after a gas outlet 31 at downstream of the regulator 56 and connected to the respective fuel supply channels 89, so as to regulate gas supplied at a primary pressure to gas at a secondary pressure in response to a predetermined signal pressure sensed from one selected from a part of the air supply passage 37 and the blower 53 and to discharge the regulated gas through the pressure regulator 56. The fuel supply channels 89 each are configured to perform fuel supply to the respective burner groups 71 and are provided with a switching valve 75 for either shutting off or reducing the fuel supply to at least a part of the burner groups 71.
