摘要： The present disclosure is related to a low-nitrogen burner, comprising a base shell including a first air inlet, a second air inlet and a vent, wherein a housing is disposed on an upper end of the base shell, an air outlet cavity is arranged between the housing and the base shell, the first air inlet, the vent and the air outlet cavity are communicated, an inner cavity of the base shell is communicated with the second air inlet, the base shell is provided with a combustion part, and wherein a fire bridge is arranged at a top edge of the housing, and the fire bridge extends to an outside of the shell. The beneficial effect of the present disclosure is that: in the present structure, a fire bridge is provided at the top edge of the shell, and the fire bridge extends to the outside of the shell. The fire bridge extends to the adjacent burner and is not affected by the air blown out of the gap, thereby improving the flame transfer stability. In the present structure, the seventh recess and the eighth recess are used to divide the flow, so that the gas flow is more uniform and fully burned.

摘要： Described is a method of incinerating material using a co-current flow technique in which the hot exhaust gases are forced to flow, by fittings mounted above the furnace grate in the primary-combustion zone, along part of the length of the grate above the grate in the same direction as the material on the grate. In a first zone (zone A), the drying zone, a temperature of less than 900 °C is maintained, in a second zone (zone B), the destructive-distillation and gasification zone, a temperature of about 1000 °C, in a third zone (zone C), the final-combustion zone, a lower temperature again of about 900 °C and in a fourth zone (zone D), the sintering zone, a temperature of less than 900 °C. The primary-combustion air is fed from the undergrate region through the grate in each zone, additional air at a temperature equal to or lower than the combustion-chamber temperature being supplied to the combsution chamber through the side walls of the combustion chamber as a covering layer.

摘要： A combustor and a corresponding method for its operation, wherein the fuel, which is pulverized coal in the illustrative embodiment, is first reacted with at least a portion of oxidizer gas flow directed to the head end (20) of the combustor. Combustion in the head end proceeds at a substantially lower stoichiometric ratio than the overall ratio for the combustor, which therefore operates at a relatively low temperature and high thermodynamic efficiency, while maintaining good slag removal characteristics. Of the several embodiments disclosed, one group has an oxidizer inlet (12) from which oxidizer gas splits into a component directed toward the head end, where the first phase of combustion takes place, head-end and a component directed toward the exit end (18), where a second phase of combustion takes place. In another group of embodiments, oxidizer is directed only toward the head-end, and the resultant exiting gas is rich in combustibles.

摘要： The afterburner plates set includes at least two fire-proof plates (1,2,3,4) made of concrete, providing a heat accumulator and carrier. The concrete plates (1,2,3,4) are placed horizontally. The top plates (2,3,4) are located above the bottom plate (1). The bottom plate (1) is provided with a through opening (5), whilst the top plate (2) is located above the top plate (1) and covers the aforementioned through window (5). The top plates (2,3,4) are shorter than the bottom plate (1) and have their bottom surface formed as parallel ridges (11) separated by grooves (12). The central heating boiler has a body with flow-connected water compartments (15), wherein the front wall (13) of the boiler is provided with an inspection door (16), whilst a retort (7) is provided in the bottom part of the both. Labyrinth-type partition elements (19) of the heat exchanger are located in the top part of the interior of the boiler, above the horizontal partition wall (18). A flue gas inlet duct leading to the heat exchanger is installed between the rear edge of the horizontal partition wall (18) and the rear wall (14) of the boiler. The concrete plates set (1,2,3,4) includes plates placed horizontally one above another.

摘要： A system, apparatus and method whereby flameless combustion is precipitated and maintained in a combustion chamber having a surface that is either convex concave, straight or any combination thereof without the need for catalysts or high temperature oxidants. The apparatus allows the combustion chamber to operate in a conventional combustion mode and a flameless combustion mode. The method provides for hot air and fuel gas to both be inerted prior to their mixing so long as their blend temperatures are within the 10000F to the 14000F range. The inert hot air and the inert fuel gas flow side by side along the chamber's internal surface so that the two gases mix more uniformly, thereby allowing flameless combustion at lower temperatures resulting in low NOx emissions.
