摘要： This invention provides an after-air nozzle and a boiler having thereof capable of reducing NOx and CO at the same time.
This invention is characterized in that it has a vena contracta (24) such that an outside diameter of a flow passage diminishes towards the air-jetting port (16) which supplies air to a boiler (18), and a changing apparatus (26-32) of a flow passage cross-sectional area to change a flow passage cross-sectional area of the vena contracta (24).
Using the after-air nozzle of this invention makes it possible to reduce NOx and CO concentrations at the same time.-

摘要： The invention provides a boiler provided with low cost means which can reduce a concentration of CO, an unburned matter, an attached ash and the like near a side wall and maintain a combustion state well with a simple structure. In a boiler having a combustion chamber 13 formed by front and rear walls (burner walls) provided with a plural stages of burners 2, 3 and 4 on at least one of them and opposing to each other, and side walls 1a and 1b crossing to said burner walls 14a and 14b, a gas port 6 containing no fuel for making a pressure of a gas near said side walls 1a and 1b within said combustion chamber 13 higher than a pressure of a gas at a center portion of said combustion chamber 13 is provided between an outermost burner and the side walls 1a and 1b within a range of a height of said burner stages 2, 3 and 4. A combustion gas 16 can not come close to the side walls 1a and 1b due to the jet 18 of the gas.

摘要： Subject
A solid fuel burner and its combustion method suited for encouraging fuel ignition and avoiding slugging caused by combustion ash, wherein a gas of low oxygen concentration (exhaust combustion gas) is used as a carrier gas of such a low grade solid fuel as brown coal.
Means for Solving the Subject
An additional air nozzle (12) for jetting additional air having a velocity component in the circumferential direction of a fuel nozzle (11) is provided in the fuel nozzle (11), thereby encouraging mixing between the fuel and air in the fuel nozzle (11). Further, the amount of air supplied from the additional air nozzle (12) is adjusted in response to the difference in combustion loads. Under light load, the amount of air supplied from the additional air nozzle (12) is increased so as to increase the oxygen concentration of the circulating flow (19) formed downstream of the outside of the outlet of the fuel nozzle (11), whereby stable combustion is ensured. Under heavy load, by contrast, the amount of air supplied from the additional air nozzle (12) is decreased, and a flame is formed away from the fuel nozzle (11) in such a way that burner structures and furnace wall will be less subjected to radiant heat.-

摘要： An overfiring air port (100) of the present invention is to supply an incomplete combustion region with air making up for combustion-shortage, in a furnace in which the incomplete combustion region less than stoichiometric ratio is formed by a burner. Furthermore, the airport is characterized by comprising: a nozzle mechanism for injecting air including an axial velocity component of an air flow and a radial velocity component directed to a center line of the air port (100) ; and a control mechanism for controlling a ratio of these velocity components.
