摘要： This invention concerns a boiler fitted with a burner suitable for wall heaters or built-in kitchen heaters in which a mantle-shaped heat exchanger made of pipe elements connected in parallel and/or series divides the boiler chamber into a combustion chamber and an exhaust chamber. The heat exchanger has openings for hot flue gases distributed over its mantle. The burner head disposed in the combustion chamber is suitable for burning oil and has a flame tube with an axial flame opening and a flame baffle element disposed at a distance from the flame opening which is constructed so that the flame is diverted into the space between the flame tube and the heat exchanger. In addition, a fire chamber mantle can be disposed between the heat exchanger and the flame tube to protect the heat exchanger from direct contact with the flame.

摘要： A round burner capable of being operated with reduced CO and NOx emissions includes a venturi tube positioned to direct a flow of air through the burner and into a combustion zone in a combustion chamber through an entrance in a wall of the combustion chamber. The venturi tube has inlet and outlet ends and a throat. The outlet end of the venturi tube has a larger internal diameter than either the inlet end or the throat and the same is positioned adjacent the entrance to the combustion chamber. The inlet end of the venturi tube is also positioned further from the entrance than the outlet end of the venturi tube. The burner may include a duct system that includes an inlet disposed in fluid communication with the combustion zone and an outlet disposed in fluid communication with the venturi tube adjacent the throat thereof. The system is arranged and adapted to recirculate a stream of flue gas from a location within said combustion chamber adjacent the combustion zone by induction into the venturi tube at a low pressure location adjacent the throat of the venturi tube so that the recirculated stream of internal flue gas is inducted into and intermixed with the flow of air at the throat of the venturi tube. Alternatively or cumulatively, the burner may include a fuel gas injector arrangement having an injector nozzle extending through the wall at a location adjacent the combustion zone. The injector nozzle is in fluid communication with the combustion chamber and is positioned to direct a flow of fuel gas into the combustion chamber at a location in the wall radially beyond the inner edge of the entrance. Also disclosed is a method for operating the burner to reduce CO and NOx emissions.

摘要： A pulverized coal burner includes a pulverized coal nozzle for jetting a mixture of pulverized coal and primary air, a secondary air nozzle and a tertiary air nozzle, concentrically arranged around the outer periphery of the pulverized coal nozzle, and a tube expanded portion at the end of a partition wall separating two adjacent air nozzles. A flow shift means such as a guide plate for shifting the secondary air in the secondary air nozzle so as to flow along the tube expanded portion is provided. The secondary air is jetted outwardly by the guide plate, and mixing of the secondary air and the tertiary air with pulverized coals is delayed, whereby an amount of NOx is decreased.

摘要： A radiant tube assembly comprises a radiant tube having a burner leg, an exhaust leg and a recuperator inside the exhaust leg and in a stream of products of combustion flowing in the exhaust leg. The recuperator has an air intake port at a first end and a mixing baffle at a second, hot end. The mixing baffle causes combustion air and products of combustion to be mixed at the hot end of the recuperator and provided to the burner leg for combustion. The mixing baffle includes a flow director which increases the amount of products of combustion mixed with the combustion air. The mixing baffle can also include a dome-shaped end which extends into the stream of products of combustion for reducing turbulence of the stream of products of combustion flowing in the exhaust leg.

摘要： In a boiler plant for heat generation, which consists essentially of a combustion space and of a burner acting on the head side of the combustion space, this combustion space is divided into two parts (17,102a) by the insertion of an annular disk (103). A limited internal backflow zone (24) forms in the front part (17) in interaction with this disk (103). This disk (103) then causes external backflow zones (106) fed by recirculated flue gases (30) to form within the front part (17) of the combustion space, the flue gases of said external backflow zones being introduced into the combustion process of the burner, said backflow zones (24, 106) being in each case separated locally from one another. Better flame stabilization, lower pulsations and markedly lower pollutant emissions can thereby be achieved when the burner is operating.

摘要： A water tube boiler using jet flames is disclosed which is capable of achieving low CO-emission combustion without enlarging a size of a combustion chamber. The water tube boiler comprises a combustion chamber 1 in which jet flames are generated and rows 3a to 3e of water tubes inserted through the combustion chamber. The group of water tubes provides a portion thick with the water tubes and a portion empty of the water tubes in a cross-section perpendicular to the direction of the jet flames, and at least the space Sa as an empty portion continuously extends through said group of water tubes in the direction of the jet flames. In the space Sa as an "empty" portion provided between the rows 3b and 3d of water tubes, recirculating flows (shown by arrows) of a combustion gas are generated. The recirculating flows are entrained by the jet flames existing the portion "thick" with the water tubes. Consequently, rapid temperature decrease of the jet flames is prevented. This enables the jet flames to flow downstream while maintaining a CO oxidation promoting temperature of about 1,000 to 1,500.degree. C., thereby promoting CO oxidation reaction. Accordingly, residual CO of an exhaust gas is greatly reduced.
摘要翻译：公开了一种使用喷气火焰的水管式锅炉，其能够实现低CO排放燃烧而不扩大燃烧室的尺寸。水管锅炉包括产生喷射火焰的燃烧室1和插入燃烧室的水管排3a至3e。一组水管在垂直于喷气火焰的方向的横截面中提供一部分与水管的一部分和水管的一部分，并且至少空间Sa作为空的部分连续延伸穿过所述组的水管在喷气式火焰的方向。在空间Sa中，设置在水管的排3b和3d之间的“空”部分，产生燃烧气体的循环流（由箭头所示）。再循环的流动被喷射火焰所夹带，并且水管中存在“厚”部分。因此，防止了喷气火焰的快速降温。这使得射流火焰在下游流动，同时保持约1000至1500℃的CO氧化促进温度，从而促进CO氧化反应。因此，废气的残留CO大大降低。

摘要： In a premix burner which essentially comprises at least two hollow conical sectional bodies (1, 2) which are nested one inside the other in the direction of flow and form an interior space (14), tangential air-inlet slots (21, 22) are formed by offsetting the center axes (1b, 2b) of these sectional bodies from one another. Feed ducts (25, 26) extend upstream of these tangential air-inlet slots, which feed ducts (25, 26) each end with an injector system (200) for the provision of combustion air (15) consisting of fresh air (19) and flue gas (20). A perforated plate (23, 24) belonging to the injector system runs parallel to the inflow planes (30, 40) of the feed ducts and is provided with injector nozzles (23a, 24a) whose inflow angle varies continuously in the longitudinal direction of the premix burner relative to the burner axis.

摘要： A burner provided for low NOx combustion of fuel with preheated combustion air in a combustion chamber of an industrial furnace and or a steam boiler has a plurality of fuel jets and at least a single air jet arranged to discharge the fuel and the preheated combustion air. The fuel jets and the air jet diverge from one another, provide dilution of fuel with combustion products, and generate multiple precombustion, combustion and post combustion reaction zones in the furnace.Thus, the burner provides the necessary process conditions and reaction zones required for minimizing the formation of prompt and thermal NOx in the precombustion and combustion reaction zones and for optimizing the decomposition of the formed NOx in the postcombustion reaction zones.
